Hybrid Cars Pros and Cons

http://www.thegreencarwebsite.co.uk/hybrid-cars.asp

Generally, and for the purposes of this guide, we will refer to hybrid cars in their most common form – HEVs.

How do hybrid cars work?

Hybrids have existed in various forms for years – the moped is one of the most common examples as it combines a petroleum engine with pedal power. Many locomotives also utilise both diesel and electric power, so the examples of hybrid vehicles are far and wide.

However, hybrid cars have been developed with the purpose of reducing carbon dioxide emissions in cars. Here, three types have emerged – series hybrids, parallel hybrids and plug-in hybrids:

  • Series hybrids – Utilise a combustion engine which generates electricity and powers an electric motor.
  • Parallel hybrids – Where the wheels are powered by the engine or by the battery-powered electric drivetrain.
  • Plug-in hybrid electric vehicles (PHEVs) – A petrol-electric hybrid with a battery pack that can be recharged.

In series and parallel hybrids, when the engine loading is low, energy is stored for later use – and when more energy is required, such as during acceleration, the storage device and main engine combine to provide the power that’s needed. By using energy in this way, hybrids are more economical and better for the environment.

Generally, hybrid cars are assisted by regenerative braking. This captures the kinetic energy and prolongs the charge of batteries. This effective top-up system for the batteries can reduce overall fuel consumption by 20 per cent. Read on for more about regenerative braking.

Plug-in hybrids run on battery power for the first 10-60 miles (16-100km) with the petrol engine used when faster acceleration is required. They are considered a good alternative to electric cars which have a limited range because plug-in hybrids revert to the petrol engine when the battery is nearly discharged – or you can go to a charging station.

Most hybrid cars are able to operate in electric mode – with zero emissions – when travelling at low speeds (for example, below 15mph). This means that they are considered ideal for urban driving.

What are the advantages of hybrid cars?

There are two primary reasons why hybrid cars have been introduced to the market – to assist the environment by reducing emissions and to cut motoring costs by reducing the reliance on oil. With more than 700million vehicles worldwide it is believed that if more consumers buy hybrid vehicles it will force car manufacturers to take a greener approach to manufacturing.

As they combine electric power with conventional burning of petroleum, harmful emissions are reduced and so is global warming. On European roads it has been estimated that petrol-hybrids can cut greenhouse gas emissions by around 25 per cent per mile. In the case of a vehicle such as the Honda Insight, which has CO2 emissions below 80g/km, lifecycle carbon emissions are actually slashed to half those of a traditional conventional car.

Indeed hybrid cars are advantageous in their reduction of all harmful emissions. Hydrocarbons, carbon monoxide and nitrogen oxides can be reduced by as much as 90 per cent.

Whether you have an environmental conscious or not, hybrid cars appeal to anyone who wants to save money – with statistics in the USA showing that the Toyota Prius can achieve approximately 60 miles to the gallon, doubling what is achievable in a conventional vehicle. With fuel prices reaching 120p/litre in the UK and $4/gallon in the USA, there are huge savings to be made over the lifetime of the vehicle.

Another advantage hybrid cars have is that they are ahead of other green car alternatives. Though electric cars, cars using biofuels, and vehicles powered by hydrogen fuel cells are emerging and may even be ‘greener’ than hybrids in the long term, they are all flawed in some way. Electric cars currently have limited range, biofuels are controversial because of the way they are produced and hydrogen fuel cells are a currently limited technology yet to be mass-produced. By comparison, hybrid cars are ‘ready to go’ in that they meet the demand of today’s society without compromise. They will also always be ahead of conventional cars in that no matter how low future emission standards may be a hybridised engine will always out-perform a conventional engine.

What are the disadvantages of hybrid cars?

There are a handful of disadvantages to hybrid cars. Though hybrids clearly reduce emissions greatly, they are less useful over continuous high speed driving, such as on a motorway where emission levels will increase. Indeed though electrics and hydrogen fuel cells are yet to be mass produced and break out into the mainstream in the manner that hybrid cars have achieved, it’s clear that they offer a stronger environmental solution should their issues be resolved.

There are also concerns over the environmental impact of the hybrid car battery which is usually made from either nickel metal hydride or lithium ion. Both are considered more environmentally friendly than lead batteries, but nickel-based batteries are known as carcinogens and there are concerns about the health problems they can cause though this is still the subject of much research.

Furthermore, there are concerns about a raw material shortage of dysprosium which is required to fabricate many of the advanced electric motors and battery systems. Some analysts predict a shortage by 2012 although a few new sources are being developed.

Plug-in hybrids also face issues of their own in that a good, cheap battery pack is required. If everyone plugged into the utility grid at the same time the combustion problems caused by petrol and diesel cars would simply be displaced by the surge in use of generally coal-powered electric generating plants. Therefore it is hoped that cars can be charged late at night to create more efficiency and that initial generation can be made from renewable sources such as wind, hydro and tide power.

However, perhaps the biggest issue with hybrid cars is that they are generally more expensive than conventional cars and the initial retail price can be off-putting. Though money can be saved over the lifetime of the vehicle, a large initial outlay is still required and this puts hybrids out of reach for many drivers.

Why have hybrid cars earned celebrity status?

Hybrid cars are sometimes referred to as the ‘car of the stars’ thanks to their incredible popularity in Hollywood. Cameron Diaz was the first to publicly announce her support of the vehicles and regularly drives a Toyota Prius. Indeed many A-list celebrities have followed her lead including Tom Hanks, Jack Black, Larry David, Harrison Ford, Woody Harrelson and Kurt Russell. Leonardo Di Caprio was also famously quoted as saying that his hybrid car is just like any other vehicle except that he only has to fill it up once every three weeks.

What is it like to own a hybrid car? How much do hybrid cars cost?

As mentioned in the ‘disadvantages of hybrid cars’, they are typically more expensive than conventional vehicles – you can expect to add around £1,000-£2,000 on to the typical retail price of a £14,000 model depending on its hybrid design.

However, once over that initial hump in buying a hybrid car, ownership becomes easy – and much more cost-effective.

Hybrid cars are refuelled in exactly the same way as conventional cars and therefore you can use any normal petrol station in the UK. This lack of a technical barrier means that hybrid cars could soon emerge as the ‘norm’ across the UK and replace standard petrol and diesel vehicles.

Aside from the huge reduction in fuel costs, typically 15-30 per cent less fuel per mile, there are other savings to enjoy. For example, if you live in the London area, most hybrid cars are exempt from the London Congestion charge though you must register with the Transport of London and pay an annual £10 fee. Nevertheless with so much to be saved on a daily basis, this exemption alone could save you around £2,000 a year if you regularly travel into London. To see if your car qualifies check out the cars that are exempt.

You will also save money by being placed in a lower tax band – typically hybrid cars fit into the tax bands A-C. If your car emits less than 100g/km of CO2 it will be exempt from taxation altogether. By contrast, a car in the highest tax band could be charged more than £400 a year.

The cost of repairs is still a question with hybrid cars. It may be necessary to go to a specialist centre, although as hybrid cars become more common this should be less of an issue.

What hybrid cars are available?

A Comprehensive Guide to Plug-in Hybrids

HybridCars.com

What Is A Plug-in Hybrid Car?

A plug-in hybrid car is similar to a conventional hybrid vehicle—both use a gasoline engine as well as an electric motor. However, a plug-in hybrid uses larger battery packs that can be recharged by connecting to common household electricity. Plug-in hybrids can be driven for long distances—from a few miles to as much as 40 miles—without using any gasoline.

http://www.hybridcars.com/files/plug-in-prius-610.jpgToyota has demonstrated a plug-in concept version of the Prius, but has not committed to a production date.

Plug-in hybrids provide the benefits of an electric car, while maintaining the same driving range as conventional vehicles. Plug-in hybrid drivers travel in an all-electric mode for the vast majority of common local driving. When the battery’s electric charge is depleted, a downsized gas engine is used to either recharge the batteries (as the car moves), or as the primary source of propulsion until recharging the batteries via a plug.

Plug-in hybrid cars are also known as plug-in hybrid electric vehicles or PHEVs. Plug-in hybrid cars that use a gas engine exclusively for recharging batteries—rather than directly powering the wheels—are also called Extended-Range Electric Vehicles or E-REVs.

Electric Cars Not the Only Option for Cleaner Air

SCMP – May 15, 2009

I applaud the government’s leading role in introducing electric vehicles (EVs) as a solution to the problem of air pollution. We finally have an alternative to driving polluting vehicles. However, I am sceptical whether they will be an immediate, widespread success.

When it comes to cars, people are brand-conscious. They care more about how the vehicles look and what they cost than they do about the environmental impact. People also tend to switch cars every few years – an issue with EVs, which offer a limited choice of models, and are apparently more expensive than many standard cars. EVs are also a new technology. I imagine many people have worries about the maintenance of the cars, and anticipate a frustrating wait for spare parts.

Our government says it has fought hard to ensure it receives at least a small quota of EVs from the manufacturer every year. This suggests the success of the scheme may be limited. For this reason, the government should consider more viable alternatives, such as allowing drivers to use ethanol-blended fuels.

High ethanol blends achieve much the same mileage as petrol, but are almost pollution-free. No modifications to vehicles are required to use an E50 blend. For higher blends, car owners only need to make a slight adjustment to pistons.

People will not have to make a sacrifice on the look or cost of their vehicles.

Triple Hybrid Fuel Cell Bus Unveiled

www.thegreencarwebsite.co.uk – 14 May 09

A presentation near Munich marked the debut of the first passenger bus to use a triple hybrid fuel cell system developed by Fuel Cell GmbH, a subsidiary of Proton Power Systems.

The vehicle has been born from co-operation between Skoda Electric, UJV Nuclear Research Institute and Proton Motor. Skoda Electric was responsible for the vehicle including its electric drive system and system integration. The project was then co-ordinated by UJV with Proton Motor supplying the propulsion system.

So how does the triple hybrid system work?

Well it combines a 50kW PM Basic A 50 fuel cell system with a battery pack and ultra-capacitors. With regenerative braking taken into account the system enables energy savings in excess of 50 per cent compared to a conventional diesel bus and is emission free in operation.

The vehicle itself is a basic 12 metre bus with a weight of 18tonnes. Its nominal output is 120kW and it has a maximum speed of 40mph. It carries around 20kg of compressed gaseous hydrogen at 350 bar and the filling process takes less than 10 minutes.

The vehicle is now scheduled to go into operation from mid-2009 onwards in Prague.

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.

Zero Emissions Motorcycle

www.alternative-energy-news.info – 13 May 09

When we think about green energy vehicles we often think about modest designs and low speeds. But 6 final-year engineering students of Kingston University have designed a bike that dispels all myths about green vehicles. This bike has the ability to reach speeds of 102mph, race around a 38 mile mountainous course and is powered by batteries that can be charged from a standard household socket! They will take this bike to the world’s first zero-emissions Grand Prix this summer. The Kingston team will be competing with 24 eco-bikes from America, India, Italy, Germany and Austria at the 2009 Isle of Man TTXGP. Mr. Paul Brandon who is the Course Director for motorsport and motorcycle engineering shared his views, “Being green doesn’t have to mean slow. There are too many skeptics when it comes to electric vehicles but we all need to reduce our CO2 output and this initiative is taking a huge leap in that direction. The ideas we and others put to the test on the racing circuit are the ones most likely to become commonplace on the road

Proton Motor and Skoda Electric Have Presented the Worlds First Fuel Cell Triple Hybrid Bus

www.fuelcelltoday.com – 12 May 2009

Proton Motor Fuel Cell and Skoda Electric today presented a preview of the worlds first fuel cell triple hybird linenbus, which will go into operation this summer in Prague.

The project is a cooperation between Skoda Electric, the systems integrator and electrical components, the UJV Nuclear Research Institute, R&D and project coordination and Proton Motor, which produced and delivered the fuel cell triple hybrid propulsion system.

The triple hybrid system is a world first combination of a fuel cell, batteries and ultra capacitors, allowing saving and further use of useful braking energy. The system is reported as saving upto 50% of energy as compared with a conventional bus drivetrain.

The chasis of the new bus is a standard 12 meter with 18 tonne combined weight. The new drivetrain allows produces upto 120 kW of power, can travel up to 65 km/hr and with a full tank can travel 250km before refuelling. The hydrogen is stored on board in 350 bar compressed cylinders and carriers 20kg of hydrogen when full.

Honda and Nissan Consider Plug-in Hybrids

HybridCars.com –  April 28, 2009

Honda and Nissan have been banking on fuel cells and electric cars as the long-term strategy for sustainable mobility. Company executives are now warming up to plug-in hybrids.

Since their introduction in the US in late 1999, hybrid cars have been repeatedly dismissed as a “bridge technology”—a euphemism for a short-lived second-rate technology that briefly serves a purpose until it can be replaced with something better and longer lasting. But in recent statements coming within days of one another, executives from Honda and Nissan are reconsidering the role that hybrids will play in the coming decades.

Honda began leasing a limited number of its FCX Clarity hydrogen fuel cell cars last year, and still sees hydrogen as the long-term alternative to gasoline. However, for the first time, Honda executives are now speaking of hybrids and plug-in hybrids as a mainstream technology with staying power. Nissan is also beginning to consider plug-in hybrids.

For both companies, the plug-in hybrid is seen as the next stage of hybrids and as the key to the technology’s longevity. Honda was banking on a transition to fuel cell cars, while Nissan was primarily moving toward the pure battery-electric vehicle.

Honda began leasing a limited number of its FCX Clarity hydrogen fuel cell cars last year, and still sees hydrogen as the long-term alternative to gasoline. But Honda President Takeo Fukui believes that the cost of fuel will need to increase before hydrogen-powered cars are ready for significant growth. In an interview published by Bloomberg, he said, “Oil prices are going to go up. When that time comes, fuel cells, solar panels, hydrogen, those will be the key words. We will have packages that will be very competitive at that time.” In the meantime, he said the company is “thinking about plug-in hybrids.” He added, “We aren’t thinking about commercializing one right away.” Honda will need to modify its current mild hybrid system—or develop a new approach—in order to produce plug-in hybrids.

The Bridge Gets Much Longer

Honda’s views on plug-in hybrids are also motivated by new consumer tax credits—as much as $7,500 for a robust plug-in hybrid. Fukui said, “We understand the situation, in terms of government and incentives. Naturally, we’re going to have to accommodate that too.”

Nissan also sees a future jump in oil prices as the key to its long-term efficient technology: the electric car. “When GDP growth comes back on a worldwide basis, there will be again attention on the oil market, which will trigger an oil price increase,” said Carlos Tavares, Nissan executive vice president. “We will be in the right tempo to face that environment.”

Mark Perry, Nissan product planner, told HybridCars.com, “Zero emission vehicles are clearly our focus and we believe it’s the future state of transportation. Some segments of the market in the near term may best be served by high efficiency internal combustion engines, diesels, hybrids or extended range electric vehicles [also known as plug-in hybrids].” He added that these technologies are “all bridge technologies to the time when battery electric vehicles and fuel cell vehicles can cover every market segment.”

The Key Question: When?

The key question for both companies is how long it will take until electric cars and fuel cell vehicles can reach levels approaching the current hybrid market. After 10 years on the market, hybrids represent less than 3 percent of the new car market.

Speaking at the Society of Automotive Engineers’ 2009 World Congress last week, Minoru Shinohara, Nissan corporate senior vice president, said that plug-in hybrids will be an important transition solution to the pure electric vehicle because they don’t need an extensive public charging infrastructure. The cost of building the public charging infrastructure will cost many billions of dollars; therefore, most analysts believe that it could take decades to construct.

Hybrids will not necessarily disappear even after an electric-recharging or hydrogen-refueling infrastructure is built. Kenji Nakano, senior chief engineer, Honda R&D, also appearing at the World Congress, said, “Hybrid technology is also applied to fuel cell vehicles, range-extender vehicles, and plug-in hybrid vehicles. Thus, instead of being a bridge technology, hybrids are expected to remain in the mainstream for quite some time.”

Second Pact To Push Electric-vehicle Use

Fanny W. Y. Fung – Apr 23, 2009

The government will today sign a memorandum with a second Japanese car manufacturer to promote the use of electric vehicles in Hong Kong, as part of its clean-air initiatives in the budget.

The news was announced by Secretary for the Environment Edward Yau Tang-wah yesterday as he appealed to legislators to support the budget. “Not only can the extensive use of clean transportation improve roadside air quality, but it can also give rise to the birth of an electric- vehicle accessory industry,” he said.

Mr Yau would arrive in Tokyo tonight to meet representatives of three car companies, an Environment Bureau spokeswoman said.

One of the companies is Mitsubishi, with which the government signed a memorandum in February. Mr Yau would take a ride in an i MiEV car, a four-seater powered by a lithium-ion battery.

One will arrive in Hong Kong next month for government departments to test its performance.

The minister would sign a memorandum with another company tomorrow, with details yet to be announced, and meet a third company to discuss electric vehicles, the spokeswoman said.

Mr Yau said the moves would help develop an electric-car market in Hong Kong. The government would continue to discuss with the business sector provision of battery-charging facilities and other infrastructure.

He is to leave Japan on Sunday to visit the Canadian cities of Toronto and Ottawa, and Washington and Boston in the US for talks on other environment-related issues before ending his tour on May 1.

Financial Secretary John Tsang Chun-wah announced in his recent budget a five-year extension of the registration-tax waiver for electric vehicles, to March 2014.

A committee headed by Mr Tsang is to study problems relating to the introduction of the vehicles.

Environmental Benefits of Electric Cars Dismissed as ‘Fiction’

By Melissa Kite, Deputy Political Editor – 18 Apr 2009

The environmental benefits of electric cars are denounced as “fiction” by new research into green methods of transport.

The amount of energy used by coal fired power stations to create the electricity to recharge electric vehicles makes them half as efficient as diesel cars, according to the research.

Britain’s carbon emissions could even go up if there is a sudden surge in demand for electric cars, the new research warned.

It will call into question a £250 million government scheme announced last week offering consumers £5,000 subsidies to buy a new electric car.

The research conducted by the group Transport Watch found that diesel powered vehicles emit approximately half as much CO2 as electric cars when the use of fossil fuels to produce electricity is taken into account.

The research paper says: “We conclude that the notion that electric cars will reduce emissions is a fiction.”

Factors making the rechargeable cars less efficient include the amount of electricity lost on the journey between the coal fired power stations which generate it and the point where it recharges the car, and the energy lost by the batteries and the motor.

The researchers calculated that of the energy burned in a power station, only a quarter reaches an electric car after leakages and losses along the supply chain are considered, giving the vehicle an energy efficiency score of 24%.

A modern diesel engine, by contrast, achieves 45% efficiency.

The research suggests that if fossil fuels are to be burned, it is much more efficient to do it within the engine of a vehicle rather than at a power station and then try to send it via the National Grid, where a lot of energy is wasted, and finally to store it in a battery which in itself might leak power.

Currently the bulk of the electricity used to charge the batteries of electric vehicles is generated by fossil fuel burning power stations.

Only 20% of UK electricity is generated by ‘clean’ methods such as nuclear power.

The research by Paul Withrington of Transport Watch concludes that CO2 emissions could actually go up if there is suddenly a big demand for electricity to recharge batteries as it would have to come from existing fossil fuel power stations.

He calculated that in China, where most generation of electricity is coal fired, electrification of diesel powered transport would double the emissions from that sector.

There are also big financial and environmental costs involved in setting up a battery charging network.

Mr Withrington said: “The government should re-examine their assumptions and should not encourage this until they have decarbonised the generating industry. At the moment, it is nuts. If you bought an electric car now you would be looking at generating the same amount of carbon or more.”

The Government’s plans have also drawn criticism from motoring groups.

Philip Gomm, of the RAC Foundation, said: “Electric vehicles are not a panacea. They are good for generating headlines but not necessarily at saving the planet, at least not in the short term. For today and tomorrow, a lot more attention needs to be paid to refining existing petrol and diesel technology, and making cars smaller and lighter as a way of saving fuel – something recognised by the Committee on Climate Change. These are proven solutions to an immediate problem.”

The RAC has also questioned where the Government derived its £5,000 incentive per vehicle figure, when previous grants to buy electric cars have been £1,000.
