Renewable Energy

A Sensible Government Would Say No To Expensive Wind Farm

SCMP – Updated on Jun 09, 2009

There has been a mixed reaction to CLP Power’s proposed erection of 67 wind turbines 135 metres high off Sai Kung.

Greenpeace said it regarded the project as a milestone for Hong Kong, though added it was a bit late compared to what has been achieved in China and Europe (“Cautious welcome for wind farm”, June 4). But the proposed scheme should be assessed on its merits and whether it can practically augment existing power supplies. Having wind turbines for the sake of establishing a milestone or success in other places can hardly be a sensible reason for their installation.

While WWF Hong Kong was concerned that the proposed wind farm would be in the flight path of migrating birds and adversely affect marine life, the Association for Geoconservation feared the wind farm would kill off the proposed geopark, because of its visual impact. Some aspects of this proposal are very clear.

The mega wind farm might cost as much as HK$2.8 billion and supply only 0.7 per cent of the city’s electricity needs. Under the proposed electricity market reform, investment in renewable energy would be rewarded with a permitted return of up to 11 per cent, according to a report in the South China Morning Post in 2006 (“Wind farm may blow more than it’s worth”). So, if the wind farm is allowed to go ahead, consumers will have to foot the bill for CLP Power’s capital expenditure and that will mean a necessary rise in the electricity tariff.

The power output from the farm – of less than 1 per cent of the city’s electricity demand – could be offset by electricity saved by simply switching off lights, appliances and equipment when not in use. This can be easily done at no cost and is environmentally most sensible. This consideration alone will surely render the proposed 200-megawatt wind farm absolutely superfluous to the city’s power requirements. Clearly, CLP Power’s proposed wind farm was never considered to benefit the city or our environment to begin with, other than the permitted return. A sensible government would certainly say no to this project.

200MW Wind Farm off Sai Kung Viable, CLP Power Says

Cheung Chi-fai, SCMP – Updated on Jun 03, 2009

An offshore wind farm at Sai Kung, capable of generating enough power for 80,000 households, was technically feasible and environmentally acceptable, CLP Power said yesterday.

The project, which the utility has been developing for three years, calls for 67 wind turbines 135 metres high near the Ninepin Islands, about 10km east of Clear Water Bay in Sai Kung. The turbines have been shifted 1km east in response to residents’ concerns about the visual impact.

“You won’t be able to see it clearly most of the time, especially in hazy weather as it is quite far away from land,” said Joseph Law Ka-chun, the project manager for CLP Power.

The farm would have a capacity of 200 megawatts – enough power for 80,000 households – avoid carbon emission, and help towards Hong Kong’s goal of getting 1 to 2 per cent of its energy from renewable sources in the next decade, the utility said.

CLP Power and its partner in the project, Wind Prospect, which designs and builds turbines, are today releasing their environmental impact assessment report, which they have submitted to the Environmental Protection Department for approval. The bureau still needs to review the business plan, and the project financing would then have to be arranged. Work would begin after 2011 and take three years.

But once completed, the wind farm, spread across 16 sq km, would be comparable to the world’s largest – 91 turbines with a 209MW capacity in the North Sea off the west coast of Denmark.

Hongkong Electric is also studying building a 100MW offshore wind farm adjacent to the CLP Power’s near Ninepin or south of Lamma Island. The utility said an estimate of the cost would only be available after detailed studies on the wind and the waves, which affect the size of the turbines. An earlier estimate by the utility, however, put the cost of a 100MW wind-farm development at about HK$3 billion.

Each CLP turbine would be set between 500 and 650 metres apart. The electricity would be transmitted via a 25km undersea cable that connected to CLP’s grid at Tseung Kwan O. If the wind was sufficiently strong and the technology worked, an alternative plan of installing 40 wind turbines of 5MW each would be considered.

The turbines would be coated only with non-reflective paint, and the air-traffic warning lights would point skywards, with the intensity carefully planned, CLP Power said. For security reasons, marine traffic in the area would be restricted to authorised vessels. But the utility has not ruled out some form of limited tourism at the site.

Mr Law said the construction method, similar to that used for offshore oil and gas drilling platforms, was endorsed by the Buildings Department after a pilot test last year.

It did not require dredging and avoided the negative impacts of conventional drilling and piling into the bedrock beneath a 30 metre layer of mud and sand.

No offshore wind farms had been built with this technology yet and the cost was similar to that of conventional piling.

Clear the Air Says – Go Hydrogen

source: www.alternative-energy-news.info

Hydrogen Powered Street Cleaner

We are hearing about many inventions and discoveries in the alternative energy sector. But we don’t get to read about many ‘actual’ finished products doing their work in real world. What we know is many models being tested in laboratories. But here we are seeing Bucher CityCat H2, the world’s first municipal utility vehicle powered by fuel cells, made its debut last week in Basel, Switzerland. This street-cleaning CityCat will be doing her work on an eighteen months trial basis. It will be a matter of study that how this vehicle nicknamed as Bucher CityCat H2 be helpful in reducing air pollution than traditional diesel engines. Empa and the Paul Scherrer Institute (PSI) have, in collaboration with Bucher Schoerling, Proton Motor, BRUSA Elektronik AG und Messer Schweiz, developed a hydrogen powered municipal street cleaning vehicle that was unveiled to the public on 14th May 2009 in Basel.

CityCat is powered by fuel cells. Fuel cells convert hydrogen into electrical current that drives the vehicle’s electric motor. So we can see that no pollutants come out from its exhaust pipe. Only water vapor is being emitted that is a result of the reaction between hydrogen and oxygen. This vehicle not only reduces pollution, but CityCat’s energy consumption is half compared to diesel engines and it reduces CO2 emissions by 40%. Such vehicles are especially useful in sensitive areas for example pedestrian precincts, railway station halls or even in enclosed structures such as exhibition halls.

Project Leader Christian Bach, Head of Empa’s Internal Combustion Engines Laboratory says, “Our aim is to take fuel cell technology from the laboratory onto the street.” The project — also named as ‘hy.muve’ i.e. (hydrogen-driven municipal vehicle) – is also used as a research platform for socio-economic studies. It can throw light on acceptance of hydrogen technology, its market introduction and its cost effectiveness.

But the big question is still unanswered; it’s about the possibility of hydrogen power. Because most of the hydrogen power is generated from non-renewable natural gas. CityCat presents a great opportunity to test whether hydrogen power is actually cost-effective for municipal use. Even if it is found to be cost-effective, hydrogen technology has a long way to go before it is accepted in mainstream vehicles.

BMW Hydrogen 7 Production

BMW has announced the start of production of the new BMW Hydrogen 7, the world’s first hydrogen-powered luxury saloon car. Destined to make its first public appearance on 28 November at the Los Angeles Motor Show, the Hydrogen 7 will be built in limited numbers and offered to selected users in 2007. The BMW Hydrogen 7 is based on the existing 7 Series and comes equipped with an internal combustion engine capable of running on liquid hydrogen or petrol. In hydrogen mode the car emits nothing more than water vapor. Powered by a 260hp 12-cylinder engine, the Hydrogen 7 accelerates from zero to 62mph in 9.5 seconds before going on to an electronically limited 143mph top speed.

YouTube: BMW Hydrogen 7

With its unique dual power engine, the driver of a Hydrogen 7 can switch quickly and conveniently from hydrogen to conventional petrol power at the press of a steering wheel-mounted button. The dual power technology means the car has a cruising range in excess of 125 miles in the hydrogen mode with a further 300 miles under petrol power. To make this possible the BMW Hydrogen 7 comes with a conventional 74-litre petrol tank and an additional hydrogen fuel tank holding up to 8kgs of liquid hydrogen. Such flexibility means the driver of a BMW Hydrogen 7 is able to use the vehicle at all times, even when the nearest hydrogen filling station is out of range.

The driver can switch between the two without any effect on driving behavior or performance. The car always gives priority to the use of hydrogen but, should this run out; it automatically switches to petrol power.

For undiluted driver enjoyment, engine power and torque in the Hydrogen 7 Unlike many previous hydrogen concept cars showcased by rival manufacturers the BMW Hydrogen 7 heralds a milestone in the history of the car. It is a full production ready vehicle, which has met all the stringent processes and final sign-off criteria that every current BMW model undergoes. A total of 100 BMW Hydrogen 7s will be built in 2007. Details on pricing and the destinations of the 100 cars will be announced at a later date.

Why hydrogen?
The BMW Group has been committed to hydrogen technology as a means of reducing car emissions, in particular CO2 emissions, for over 20 years. When running in the hydrogen mode, the BMW Hydrogen 7 essentially emits nothing but water vapor. And, unlike fossil fuels and traditional petrol, hydrogen is available in virtually infinite supply when renewable energies such as solar, wind and wave power are used to produce the liquid hydrogen. Stored in a hi-tech tank which keeps the fuel at a pressure of 3-5 bar and a consistent temperature of -250C, liquid hydrogen offers significant advantages in energy density compared to other possible alternative fuel sources to enhance the cruising range of the car.

BMW continues to develop ultra efficient, yet very dynamic petrol engines that significantly reduce fuel consumption and CO2 emissions. Together with clean performance diesel cars and the technologically advanced hybrid systems currently under development, the BMW Group has a clear strategy for sustainable mobility with hydrogen as the ultimate goal.

Future Hydrogen Fuel Cell Cars

September 30th, 2006

Forget ethanol or biodiesel. The next big thing in automotive fuel may very well be hydrogen. Automakers rapidly are closing in on making hydrogen fuel cell vehicles an everyday fact of life, with several test models set to debut over the next few years. Hydrogen fuel cells to power vehicles is desirable, experts say, because hydrogen is a renewable fuel that can be used to create electricity to run cars. A chemical reaction between oxygen and hydrogen produces the electric power, and when pure hydrogen is used, the only emission from the tailpipe is harmless water vapor.

Can China Clean Up Its Act?

BusinessWeek by Adam Aston – May 14, 2009

Beijing has big plans to curb pollution and start a cleantech industry. But the global recession and looming trade frictions will test its resolve

China’s unprecedented growth in recent years has come at a terrible price. Two-thirds of its rivers and lakes are too polluted for industrial use, let alone agriculture or drinking. Just 1 in 100 of China’s nearly 600 million city dwellers breathes air that would be considered safe in Europe. At a time when arable land is in short supply, poisoned floodwaters have ruined many productive fields. And last year, ahead of most forecasts, China passed the U.S. to become the world’s largest source of greenhouse gases.

The immensity of these troubles has produced a result that may surprise many outside China: The nation has emerged as an incubator for clean technology, vaulting to the forefront in several categories. Among all countries, China is now the largest producer of photovoltaic solar panels, thanks to such homegrown manufacturers as Suntech Power (STP). The country is the world’s second-largest market for wind turbines, gaining rapidly on the U.S. In carmaking, China’s BYD Auto has leapfrogged global giants, launching the first mass-produced hybrid that plugs into an electrical outlet. “China is a very fast follower,” said Alex Westlake, a director of investment group ClearWorld Now, at a recent conference in Beijing.

GOVERNMENT SUPPORT

Understanding they are in a global race, China’s leaders are supporting green businesses with policies and incentives. Beijing recently hiked China’s auto mileage standards to a level the U.S. is not expected to reach until 2020. Beijing also says it will boost the country’s share of electricity created from renewable sources to 23% by 2020, from 16% today, on par with similar targets in Europe. The U.S. has no such national goal.

While most environmentalists applaud these developments, China watchers are voicing two very different sets of concerns. Some question whether China will really stand by its ambitious targets and are worried by signs of backsliding as the recession in China’s key export markets drags down economic growth. Another group, interested mainly in America’s own industrial future, fears that China’s growing dominance in certain green technologies will harm budding cleantech industries in the U.S. After all, China’s emergence comes just as the Obama Administration is trying to nurture these same types of ventures, hoping to generate millions of green jobs. Many of these U.S. businesses will have trouble holding their own against low-price competitors from China.

Beijing’s green intentions will soon be put to the test. China is in the midst of the biggest building boom in history. A McKinsey & Co. study estimates that over 350 million people—more than the U.S. population—will migrate from the countryside into cities by 2025. Five million buildings will be added, including 50,000 skyscrapers—equal to 10 New York Cities. And as quickly as new offices and houses multiply, they are filled with energy-hungry computers, TVs, air conditioners, and the like, sharply increasing demand for electricity, which comes mainly from coal-powered plants.

Environmental groups say it is therefore critical that Beijing promote rigorous, greener standards. And to some degree, that’s happening. A government mandate states that by the end of next year, each unit of economic output should use 20% less energy and 30% less water than in 2005. Portions of Beijing’s $587 billion economic stimulus package are earmarked for cleantech. On top of that, in March the Finance Ministry unveiled specific incentives to spark solar demand among China’s builders. Included was a subsidy of $3 per watt of solar capacity installed in 2009—enough to cover as much as 60% of estimated costs to install a rooftop solar array.

USING WASTE HEAT
Steps like these will help Himin Solar Energy Group in Dezhou, Shandong Province. Founded in 1995 by Huang Ming, an oil equipment engineer turned crusader against the use of fossil fuels, the company is the world’s largest producer of rooftop piping systems that use the sun’s rays to heat water. Its eye-catching headquarters, the Sun-Moon Mansion, showcases these heaters, which Himin cranks out in immense volumes—about 2 million square meters’ worth each year, equal to twice the annual sales of all such systems in the U.S. Because its water heaters sell for as little as $220, they are becoming standard in new housing complexes and many commercial buildings across the country.

Broad Air Conditioning, based in Changsha, Hunan Province, is also set to profit as Beijing pushes toward its green targets. By using natural gas and so-called waste heat from other machines and appliances instead of electricity, Broad’s big chillers can deliver two to three times more cooling per unit of energy than a conventional unit. In a similar fashion, Haier, headquartered in Qingdao, Shandong Province, combines low-cost manufacturing and a variety of advanced technologies to create affordable, energy-sipping refrigerators and other appliances. During the 2008 Beijing Olympics, Haier supplied more than 60,000 such devices for visiting athletes and tourists to use.

As these and other domestic players bump up against technological obstacles, they can draw on the expertise of many of the world’s top multinationals. In return for access to its domestic market, Beijing asks such companies as General Electric (GE), DuPont (DD), 3M (MMM), and Siemens (SI) to share their technology, help upgrade their China-based supply chains, and spread industrial processes to make manufacturing more efficient. These aren’t simply green practices, says Changhua Wu, Greater China director of the Climate Group, a consultancy in London that partners with companies to combat climate change. “They’re best practices.”

GE, for example, has transferred expertise to Chinese partners in everything from wind turbine construction to the building of low-pollution factories. At the Beijing Taiyanggong power plant, waste heat from the combustion process is recycled, resulting in around 80% efficiency, more than double the rate of most conventional power plants in the U.S. The bulk of GE’s sales of turbines for power plants in China are the ultra-efficient models. David G. Victor, a Stanford University professor who has studied China’s electric grid, says some of the coal plants being built there are “much more advanced than those we see in the U.S.”

Wal-Mart Stores (WMT), which buys some $9 billion worth of goods in China each year from some 20,000 vendors, infuses its supply chain with the latest ideas about energy efficiency. For example, Chinese factories that work with Wal-Mart are obliged to track vast quantities of data on energy use and make the information available for audits. “Many Western companies can’t track their own energy consumption,” says Andrew Winston, consultant and co-author of the book Green to Gold.

TORPEDOING U.S. SOLAR?
China’s early achievements in cleantech owe a lot to collaborations such as these. The benefits: China cleans up its own pollution, and the government-backed initiatives in solar and wind help drive down the cost of renewable energy systems in countries around the world.

But there is a downside. The rock-bottom prices for made-in-China green technology could make it impossible for cleantech ventures in the U.S., Europe, or Japan to compete. How, for example, will they go up against Suntech Power, based in Wuxi, Jiangsu Province, the world’s lowest-cost manufacturer of standard solar panels? The U.S. boasts plenty of advanced technology. But any efforts by Washington to nurture this sector could be quickly undercut by a flood of Chinese-made solar panels. Such a deluge is likely if there is a big increase in public subsidies for rooftop solar systems. “What [that would] do is create 10,000 Chinese jobs,” says Roger G. Little, chief executive of Spire Corp. (SPIR), a leading U.S. maker of manufacturing equipment for photovoltaics. “If we import all the [solar] modules, it will obliterate U.S. manufacturing” in this area.

A similar scenario exists in the much heralded area of electric vehicles. BYD, headquartered in Shenzhen, started selling its first plug-in hybrid, the F3DM, last year. It beat Toyota (TM) and General Motors (GM), both of which are developing such “plug-ins,” and hit the market with a price tag they probably can’t match: just $22,000. Henry Li, a BYD general manager, says the company will roll out a version of the car in the U.S. in 2011. Chevy’s answer to this car, called the Volt, is expected to cost about twice as much and won’t be out until next year.

How did BYD pull off this coup? Part of it is just being the new kid on the block. Today’s automobiles, with their advanced combustion engines, are the most complex mass-produced goods ever made, assembled from thousands of highly engineered parts provided by a web of suppliers. It’s difficult for a Chinese startup to compete on such a sophisticated playing field. But the emergence of a new, green-vehicle category clears the way. BYD was able to break in by leveraging its background as a battery maker. When it ran into technical hurdles, the company could draw on a deep pool of inexpensive, well-trained talent at China’s top engineering schools. BYD is also a leader in pure electric vehicles, the logical next step. The government is now putting some muscle behind BYD’s push. It is heavily subsidizing electric-car sales in about a dozen cities—in a stroke, making China the world’s biggest market for such advanced vehicles. Its goal is to boost domestic output of battery-powered vehicles to a half million per year in 2011.

How Washington and the beleaguered U.S. auto sector might respond to a wave of inexpensive electric vehicles from China is difficult to predict. And it is also unclear how China’s cleantech efforts in cars, energy, and other areas will be affected if key markets such as the U.S. and Europe don’t recover quickly from the recession. Chinese makers of solar photovoltaics, including Suntech, export about 98% of their production. They have been battered this year by a collapse in demand in Germany, Spain, and Japan, China’s top markets for solar gear. Suntech’s factories are currently running at half of last year’s capacity.

Even inside China, academics and business executives say Beijing needs to do more to bolster cleantech initiatives and make them recession-proof. For example, without better information on how such policies as the current Renewable Energy Law are to be enforced, “many of the terms are meaningless,” complains Himin’s Huang. And even when the terms are clear, companies don’t always adhere, says Zhou Weidong, the Guangzhou-based China director at the Business for Social Responsibility, a global consultancy promoting sustainable business practices: “Paying penalties is cheaper than complying with the law in many areas.”

At times, it seems as though Beijing is pedaling in the wrong direction. Late last year, China’s Environmental Protection Ministry loosened review standards on potentially polluting industrial projects. In an economic crunch, “environmental protection is downplayed to second, or third, or even fourth priority,” observes Guo Peiyuan of SynTao, a corporate social responsibility advisory firm in Beijing.

While acknowledging there has been some backsliding, most China watchers say the government is unlikely to stage a full-throttle retreat. Too much of its export growth is contingent on meeting strict environmental regulations. And Beijing recognizes that Chinese society can’t tolerate much more environmental degradation. The World Bank estimates damage from pollution—everything from decimated fisheries to premature human death—saps nearly 6% of China’s gross domestic product each year as well. For economic reasons alone, it will be difficult for China to turn back the clock.

China to Focus on Renewable Energy

Kari Cameron, Voice of America – 1 May 2009

China is battling air pollution and high costs for imported energy with an aggressive focus on renewable energy.

ap_china_renewable_energy_01may09_210

Workers build a highway near a wind farm in the Gobi desert, in China's northwest Gansu province (File)

China’s government says it will have 100 gigawatts of wind-power capacity by 2020 – enough to power more than 60 million homes. That figure is more than three times the target the government laid out just 18 months ago.

Steve Lyons is the director of CWE Renewables, a wind energy company based in Hong Kong. His company is setting up wind farms in Inner Mongolia, funded mainly by Chinese investors. Despite the global economic crisis, the company has seen continued interest from investors and from provinces.

“There are provinces that have good wind resources, no wind capacity, and have asked us to help them put in place what needs to be put in place for a wind developer to come in,” he said.

China’s government has vowed to increase the use of alternatives to oil and coal for energy, such as wind, solar and nuclear power. The goal is to reduce the thick air pollution that blankets its cities and to reduce expensive imports of oil.

Companies from start-ups to well established businesses such as General Electric, see China’s drive to clear the air as an opportunity. They are tapping the market hoping to capitalize on Beijing’s push to for cleaner energy sources.

Renewable energy could play significant role

Adrian Ho is the director of CWE Renewables. He thinks China’s use of renewable energy will increase in coming years to play a significant role in meeting the nation’s energy needs.

“There is a high chance that I believe China will go to 25 percent some day and that 25 percent will keep expanding,” he said.

Today, renewable sources produce just eight percent of China’s total energy. But Beijing aims to increase that to 15 percent by 2020. In comparison, the United States hopes to generate 10 percent of its energy from renewable sources by 2012.

The roots of China’s push for renewable energy are in a 2005 law that gives incentives such as fixed rate tariffs and carbon credits to renewable-energy companies. The law also makes clear that provinces are expected to meet new clean energy guidelines.

Chris Flavin is the president of the Worldwatch Institute, a U.S. environmental group. He says the law works thanks to China’s entrepreneurs and a government that is making the move to clean energy a priority.

“The Chinese government, I guess in part of the fact that it does not have some of the kind of democratic complexities that Western countries do, is able to do things quicker and without the kind of resistance from narrow economic interests that might make it more difficult,” said Flavin.

China’s wind energy capacity has doubled

The World Wind Energy Association says China’s wind energy capacity has doubled every year since the law was put in place, to 12 gigawatts. Wind is the fastest growing renewable energy in China, with 60 percent more capacity since 2005.

But pollution takes much longer to clean up than it does to create. China is failing to hit targets for bringing pollution and carbon emissions under control.

U.S. Secretary of State Hilary Rodham Clinton has said she will push developing nations such as China and India to commit to reducing carbon emissions as part of a new international treaty on fighting climate change. Emissions from fossil fuels, such as coal and oil, are thought to contribute to global warming.

Flavin says that it is not that China does not want to reduce emissions – the problem is their lack of a better option.

“The main driving force is that China is not rich in any fossil fuel except for coal and coal is a heck of a lousy way to fuel an economy,” he said.

Stimulus plan is helping

Things are changing. Wind and nuclear power are getting a boost from China’s almost $600 billion economic stimulus plan, which promises to help with grid infrastructure and nuclear development.

“If you look at where we are today and compare with what anybody might have expected or even hoped for five years ago, I think it’s really extraordinarily encouraging what they’ve accomplished,” Flavin added.

As China continues to build its renewable energy capacity, the world’s most populous nation is emphasizing that clean energy is not a luxury but a necessity for its survival. Renewables will help reduce pollution in the long term, quelling Beijing’s concerns about social unrest over pollution-related illness. China also needs clean energy to increase its role on the global stage – a lack of natural resources make clean energy the only possibility for China to achieve energy independence.

CLP To Pay HK$730m For Wind Power Assets

Denise Tsang, SCMP – Apr 08, 2009

Electricity supplier CLP Holdings (SEHK: 0002) has agreed to buy mainland wind-power projects from its Australia-based partner for HK$730 million, making its first move to restructure its renewable energy investments overseas.

The deal involves the acquisition of a 49 per cent stake in 10 wind farms largely in Jilin and Shandong provinces from Roaring 40s Renewable Energy, a 50-50 joint venture between CLP and Hydro Tasmania of Australia.

The acquisition will add 122 equity megawatts to CLP’s renewable energy capacity, increasing it to more than 1,200MW, or 9 per cent of its total generation capacity.

To lift the renewable energy capacity ratio to 20 per cent of its total generation capacity by 2020, CLP yesterday said it would acquire Roaring 40s’ green energy portfolio in India “in the near future”.

A CLP spokesman said the India acquisition involved one wind farm. The price is still being negotiated.

Group chief executive Andrew Brandler said the restructuring of ownership of Roaring 40s’ mainland portfolio would instantly boost CLP’s exposure to the country’s fledgling green energy market while bringing its target non-carbon-emitting generating capacity closer to reality.

The company would keep its interest in Roaring 40s, which would in turn focus on renewable investments such as geothermal and solar energy in Australia after the asset restructuring, he said.

Two of the 10 wind farms are in Jilin and one in Shandong. The rest were under construction, a CLP spokesman said.

Some analysts said investment on renewable energy development was commercially viable on the mainland because of incentives such as lower tax, higher on-grid tariffs and government subsidies.

CLP, which has been accused by green groups of being Hong Kong’s biggest polluter, has aggressively expanded its clean-energy investments in hydro, wind, biomass, solar and geothermal power on the mainland, in Australia, India, Thailand and Laos as part of its non-carbon-emitting vision for 2050.

Mainland Allows HK Firms To Run Green Projects – Relaxed Rules Give Conditional Access To Greenhouse Gas Market

Cheung Chi-fai, SCMP – Apr 08, 2009

Hong Kong companies will receive conditional access to massive carbon-reduction markets across the border after mainland authorities eased the eligibility rules.

The change came about after the National Development and Reform Commission “reinterpreted” the rules recently, Secretary for the Environment Edward Yau Tang-wah said.

Beijing had previously insisted that only companies with at least half their equity supplied by Chinese capital in a strict sense would be eligible to develop projects on the mainland under the Clean Development Mechanism (CDM).

Now, it says Hong Kong-registered companies based in the city and run by Chinese nationals or Hong Kong permanent residents who constitute half of the company’s board membership will also be acceptable.

Other criteria include a minimum threshold of 50 per cent of non-circulating shares for a listed company.

Under the UN-supervised CDM – the world’s second-biggest greenhouse-gas market after the European Union’s emissions-trading system – developing countries can sell certified emission reductions generated from qualified projects, such as renewable energy, to developed nations to meet their Kyoto Protocol commitments to cut carbon emissions.

The changes will put Hong Kong back into the growing CDM market on the mainland, which is the biggest supplier of CDM projects in the world, accounting for a third of the 1,500 projects already registered with the UN. The mainland is estimated to deliver more than 100 million credits a year from the projects, with each credit equalling a tonne of carbon reductions.

Mr Yau, who said he had been informed of the change in Beijing last week, hailed it as a “turning point”.

He said Hong Kong companies were set to benefit from new business opportunities in the huge CDM market all over the mainland.

But it would be difficult to assess what kinds and sizes of companies would benefit from the relaxed rules as they would still have to satisfy the national requirements for qualifying CDM projects, he said.

“The most important thing in the change is that it has lowered the bar for entering the market,” Mr Yau said. “Without that, no matter how big or small a company is, it just can’t participate.”

Industry sources said local utilities such as CLP Power (SEHK: 0002), which had a growing investment in renewable energy such as wind or hydro power, would be major beneficiaries.

The Hong Kong General Chamber of Commerce, which had advocated the change for some time, said it would allow genuine Hong Kong companies to take part in the green-technology market on the mainland.

Last year, Beijing also relaxed rules for CDM projects in Hong Kong, allowing companies registered in the city to develop projects without paying the administrative fee imposed on the mainland.

William Yu Yuen-ping, head of WWF Hong Kong’s climate programme, said the change might draw more companies to Hong Kong – including those that specialise in verifying and certifying CDM projects.

ANALYSIS-In Big Green Push, Australia Thinks Too Small On Solar

Reuters By Leonora Walet and Bruce Hextall – Wed Apr 8, 2009

HONG KONG/SYDNEY – At first glance, a new day seems to be dawning for the overshadowed solar sector in Australia, the world’s sunniest continent.

The government is pushing through a carbon trading scheme that will penalise big greenhouse gas emitters; a major piece of renewables legislation is due for approval within months, setting a target of 20 percent green energy by 2020.

But supporters say these shiny targets may be undermined by policymakers who think too small — limiting the most generous rebates for renewables to the first 1,500 watts of capacity, or about half the minimum of the 3,000-5,000 watts used by the average Australian home.

“The limit of something like 5 KW would have been a really useful driver,” said Muriel Watt, chair of the Australian Photovoltaic Association. “But the limit being 1.5 KW, it’s not going to drive the large systems we’d like to see.”

Australia draws just about 5 percent of its electricity from renewable sources, mostly hydropower and wind. Solar power comprises less than one percent.

The Clean Energy Council, Australia’s main clean-tech body, has urged the government to raise to 200 KW the limit for renewable energy installations eligible for generous rebates.

Instead, say campaigners, Australia needs to adopt a nationwide feed-in tariff structure that would allow users to generate revenue by selling excess power back to the grid.

Such “feed-in” tariffs in Germany, for example, led to the country’s solar power installations increasing 11-fold since it introduced a generous gross feed-in tariff eight years ago.

China and Japan are also ramping up solar investment, with China last month announcing a subsidy of 20 yuan ($2.93) per watt peak for large solar projects. Japan offers a further $200 million subsidy to boost home solar panel usage for the year from April 1 after a $90 million outlay from January to March.

Australia’s policies have not proved as enticing. BP Plc’s (BP.L) solar unit in Sydney, which operated the only panel-making plant in the country, closed down last month to cut costs.

That leaves the Australian market open to Japan’s Kaneka Corp (4118.T) Sanyo Electric Co Ltd (6764.T) and Sharp Corp (6753.T), and China’s Suntech Power (STP.N) and JA Solar (JASO.O).

Australian firms that have persevered despite the obstacles include electricity and gas supplier Origin Energy Australia (ORG.AX), Dyesol (DYE.AX) and Silex SLX.AU, which are working on individual solar cell technologies.

“GREENHOUSE MAFIA”

Solar, though, remains costly compared with wind power, and particularly with coal, which generates 80 percent of Australia’s energy, making it one of the most coal-reliant nations in the world.

“That’s one of the hardest things for us to compete against. There’s a real inadequacy of government programmes and inconsistencies but whatever they do it’s still competing against cheap brown coal,” said Simon Troman, vice-president of the Australian and New Zealand Solar Energy Society.

He said coal-fired power generators had long enjoyed subsidies from taxpayers, with for example, transmission lines linking power stations being built for free.

The coal lobby — together with other carbon-intensive export-oriented industries such as mining — also wields tremendous political influence, not only because of the higher costs but for fear of unstable electricity supplies in a country that regularly faces sporadic shortages.

“Everyone knows perfectly well what’s holding things back,” said renewable energy policy expert Mark Diesendorf of the Institute of Environmental Studies at the University of New South Wales in Sydney.

“It’s a group called the greenhouse mafia. It consists of the coal industry, oil, aluminium, iron and steel, cement and motor vehicle makers,” he told Reuters.

The government has backed mandatory renewable energy target legislation (MRET) that ramps up existing targets to 20 percent national green energy production by 2020. Parliament is expected to pass the law within months.

The law is expected to attract renewable energy investment of A$20 billion to A$30 billion by 2020, with wind power capturing the most investment initially, analysts say.

LITTLE INCENTIVE

Australian states and territories have introduced, or want to introduce, schemes to reward householders for power fed back into the grid. But so far, only the tiny Australian Capital Territory has opted for the more generous gross feed-in tariff from March this year for systems up to 30 KW.

Solar Shop Australia, the country’s largest installer of domestic solar systems, wants the federal government to implement a national gross feed-in tariff, instead of the less generous nett tariff backed by most states.

Diesendorf said there was no incentive for large-scale solar power from the federal government, a view echoed by the manager of an energy systems supplier.

“Even for very small commercial installations of 20 to 50 KW on buildings or small farms, there’s very little incentive,” said the manager, who did not want to be named. “The feed-in tariffs designed in most states exclude commercial solar projects.”

But engineering firm WorleyParsons Ltd (WOR.AX) announced plans last year to build the world’s largest solar plant, a 250 MW project, in Australia.

The plan would be reliant on big mining firms funding the A$1 billion ($710 million) project. Mining firms want to invest in renewable power to cut fuel costs and curb carbon emissions to meet targets under national emissions trading, expected to begin in the middle of next year.

WorleyParsons said it aimed to deliver 40 percent of Australia’s renewable energy needs with 34 solar power plants by 2020 but carbon credits would have to be priced at well over A$10 a tonne to make the solar power plants commercially viable.

The government estimates credits under its scheme will initially trade above A$20 a tonne of carbon pollution. (A$=71 U.S. cents) (Additional reporting by David Fogarty; Editing by Clarence Fernandez)

4 Clean-energy Plants Approved

Eric Ng in Beijing, SCMP – Updated on Mar 13, 2009

The central government has approved the construction of four clean-energy projects that could cost up to 19.8 billion yuan (HK$22.45 billion), as part of the country’s effort to reduce pollution.

The National Development and Reform Commission yesterday said it had given China Huadian Group the green light to build the 920-megawatt (MW) Luding hydropower station on Dadu River in Sichuan province.

It had also approved the construction of the 880 MW Dongqingshui hydropower project on Beipan River in Guizhou autonomous region by mainland-listed Guizhou Qianyuan Power.

China Huadian, one of the five state-owned generation firms, is the parent of Hong Kong and mainland-listed Huadian Power International Corp.

The top economic policy planner has also cleared the 100.5 MW second-phase wind farm development in Rudong, Jiangsu, by China Longyuan Electric Power Group, a unit of China Guodian Group – one of the five state power majors.

Huadian Power’s 100.5 MW Guyuan wind farm in Hebei province also gained approval.

An Asia utilities analyst said the cost of building hydropower plants in China ranges from 6 million yuan to 10 million yuan per MW, while that of wind power varied between 7 million yuan and 9 million yuan.

Based on these figures, the total investment cost of the four projects, with a combined capacity of 2,001 MW, could reach 19.8 billion yuan.

The National Energy Commission plans to build six large wind farm bases, each with more than 1,000 MW of capacity, in Inner Mongolia, Gansu, Xinjiang, Hebei and Jiangsu provinces and autonomous regions, according to Xinhua.

Inner Mongolia has the most ambitious plan, with 5,000 MW of capacity.

According to a long-term renewable energy plan released by the NDRC in mid-2007, Beijing wants to raise the country’s hydropower generating capacity to 190,000 MW next year and 300,000 MW in 2020, from 171,520 MW at the end of last year.

Wind power capacity is targeted to rise to 5,000 MW next year and 30,000 MW by 2020. Next year’s target has now been exceeded, as capacity stood at 8,940 MW last year-end.

Beijing aims to have 10 per cent of the national energy consumption coming from renewable sources by next year and 15 per cent by 2020. The ratio was 8 per cent last year.

Hydrogen Fuel From Non-food Sources

February 21st, 2009 – Alternative Energy

Tomorrow our vehicles may derive power by enzymes. These enzymes may originate from the cellulose of woodchips or grass and instead of emitting poisonous gases they will exhale hydrogen. We know that when hydrogen is burned, the only emission it makes is water vapor, so a key benefit of hydrogen fuel is that when burned, carbon dioxide (CO2) is not produced. Clearly, hydrogen is less of a pollutant in the air because it omits little tail pipe pollution. Hydrogen also has the potential to run a fuel-cell engine with better effectiveness over an internal combustion engine.

A team of scientists from Virginia Tech, Oak Ridge National Laboratory, and the University of Georgia says it has successfully generated hydrogen gas. Normally these kinds of fuels are derived from starch. Jonathan Mielenz, who is the leader of the Bioconversion Science and Technology Group at ORNL, says, “It is exciting because using cellulose instead of starch expands the renewable resource for producing hydrogen to include biomass.”

This hydrogen gas is clean enough to power a fuel cell by combining 14 enzymes, one coenzyme, cellulosic materials from non-eatable sources, and water heated to about 90 degrees Fahrenheit (32 C). The researchers utilized cellulosic materials which is isolated from wood chips. But researches also claim that crop waste or switchgrass could also be used for this purpose. These research outcomes are being published in ChemSusChem. The research is supported by the Air Force Office of Scientific Research; Zhang’s DuPont Young Professor Award, and the U.S. Department of Energy.

Percival Zhang who is assistant professor of biological systems engineering in the College of Agriculture and Life Sciences at Virginia Tech, states, “In addition to converting the chemical energy from the sugar, the process also converts the low-temperature thermal energy into high-quality hydrogen energy – like Prometheus stealing fire.” This group declares the benefits of their “one pot” process. The first advantage is they are using a unique combination of enzymes. The second advantage is that hydrogen generation rate is as fast as natural hydrogen fermentation. The third advantage is the chemical energy output is greater than the chemical energy stored in sugars. The maximum hydrogen yield is produced from the cellulosic materials.

Percival Zhang said that if we can utilize a small fraction (two or three percent) of annual biomass production (at global level) for sugar-to-hydrogen fuel cells for transportation, it can lead us to transformational fuel independence. For U.S.A. the figure varies a bit. If U.S. wants to get rid of fossil fuels from transport they actually need to convert about 10 percent of biomass – which would be 1.3 billion tons of usable biomass.
