Vehicle air pollution emissions are being successfully tackled in many countries by technical solutions such as low-sulphur fuels, unleaded petrol and three-way catalytic converters. Many researchers advocate a similar approach for overcoming transport's climate change impacts. This study argues that finding a technical solution for this problem is not possible. Instead, the world will have to move to an alternative surface transport system involving far lower levels of motorised travel.Keywords:Green mobility; Fuel efficiency; Alternative fuels; Global climate change; air pollution1. IntroductionProvision of environmentally sustainable (or green) private transport throughout the world faces two main challenges. The first is urban and even regional air pollution, particularly in the rapidly growing cities of the industrialising world. The second is global climate change, caused mainly by rising concentrations of greenhouse gases (GHGs) in the atmosphere. These two barriers to green car mobility differ in several important ways. First, road traffic air pollution problems are more localised, because of the short atmospheric lifetimes of most vehicle pollutants and . Thus regional solutions are often not only possible, but also essential – Australian cities, for example, can (and must) solve their air pollution problems themselves. Matters are very different for global climate change. Except possibly for geo-engineering measuressuch as placing large quantities of sulphate aerosols in the lower stratosphere or erecting huge reflecting mirrors in space, one country cannot solve this problem alone. Climate change is a global problem. Nevertheless, it is possible for some countries to ‘freeload’ if the majority of nations that are important GHG emitter。

New Energy Vehicles: Driving the Future of Sustainable TransportationIn the contemporary era of rapid technological advancements, the automotive industry is undergoing a paradigm shift. The emergence of new energy vehicles (NEVs) represents a significant milestone in this transition, heralding a new era of sustainable transportation. These vehicles, powered by alternative sources of energy such as electricity, hydrogen, and solar, are revolutionizing the way we travel, reducing our dependency on fossil fuels and mitigating the environmental impacts of traditional automobiles.The rise of NEVs is not just a technological trend;it's a societal imperative. With the escalating concerns over climate change and air pollution, the need for eco-friendly modes of transportation has become increasingly urgent. NEVs offer a viable solution, offering reduced emissions, improved fuel efficiency, and quieter operation. This shift towards sustainability is not only beneficialfor the environment but also presents economicopportunities, driving innovation and job creation in the automotive sector.One of the most prominent types of NEVs is electric vehicles (EVs). These vehicles are powered by batteries, eliminating the need for internal combustion engines and the associated emissions. The popularity of EVs has grown significantly in recent years, with an increasing number of manufacturers offering a diverse range of models, from compact cars to heavy-duty trucks. The development of advanced battery technology has been a key driver in the widespread adoption of EVs, enabling longer driving ranges and faster charging times.Another noteworthy area in the NEV landscape is hydrogen fuel cell vehicles. These vehicles use hydrogen as a fuel source, converting it into electricity through a chemical reaction. This process produces only water as a byproduct, making hydrogen fuel cell vehicles truly zero-emission. While the infrastructure for hydrogen fueling stations is still in its infancy, the potential of this technology is immense, offering a clean and efficient alternative to fossil fuels.Moreover, the integration of renewable energy sources such as solar power into NEVs is gaining momentum. Solar-powered vehicles harness the sun's energy to charge their batteries, further reducing their carbon footprint. While solar-powered vehicles may not yet be suitable for all types of transportation, they represent a promising direction for future development.However, the widespread adoption of NEVs faces several challenges. One of the primary concerns is the cost of these vehicles, which is often higher than traditional gasoline-powered cars. Government incentives and subsidies can help offset these costs and encourage consumers to make the switch. Additionally, the infrastructure for charging stations and hydrogen fueling facilities needs to be expanded to support the growing number of NEVs on the road. Another challenge is the need for standardized charging and fueling protocols. Different manufacturers often use proprietary systems, which can create inconveniences for consumers. Establishing universal standards would greatly enhance the usability and adoption of NEVs.Despite these challenges, the future of NEVs looks bright. As technology continues to evolve and costs come down, these vehicles are expected to become more accessible and widespread. Innovations in battery technology, charging infrastructure, and renewable energy integration willfurther enhance the performance and sustainability of NEVs. Moreover, the automotive industry is collaborating with governments, research institutions, and other stakeholdersto address the challenges facing NEVs. These collaborations are focused on developing new technologies, improving infrastructure, and creating policies that support the widespread adoption of sustainable transportation solutions. In conclusion, new energy vehicles represent a pivotal shift in the automotive industry, ushering in a new era of sustainable transportation. While challenges remain, the potential benefits of NEVs are immense, offering reduced emissions, improved fuel efficiency, and economic opportunities. As technology and infrastructure continue to evolve, we can expect to see a growing number of NEVs onour roads, driving us towards a more sustainable future.**新能源汽车:驱动可持续交通的未来**在当今科技飞速发展的时代,汽车行业正经历着范式转变。

The electric car — a green transport revolution in the making?As the world's continuing energy crisis, and war and oil consumption and energy ----- car full with the amount of increase, decrease energy day by day, one day it will disappear without a trace. Oil is not living resources. Oil consumption in the net must be to find a substitute before. With the development of technology and social progress, the invention of the electric vehicles will be effective help ease the financial difficulty. Electric cars will become the ideal means of transport.Faced with high energy costs and rising consumer and government concern over the fate of the environment, the world's automakers are stepping up investment in the development of alternative power train technologies that promise to substantially cut fuel consumption and reduce greenhouse gas emissions.Much attention to-date has focused on advances by Japanese and American automakers in the development of hybrid and battery electric vehicles. Toyota's,Prius has emerged as the best-selling hybrid car in the world. TesIa Motors, a US-based start-up, has launched its first battery electric vehicle, the Tesla Roadster. By the end of 2010, GM plans to launch its much-touted Volt hybrid, while Chrysler has recently announced similar plans.The Chinese government also has the National High Technology Research and Development Program (863 Program) specifically listed, including hybrid vehicles, including electric cars of major projects. At present, China's independent innovation of new energy vehicles in the process, adhere to the government support to core technology, key components and system integration focusing on the principles established in hybrid electric vehicles, pure electric vehicles, fuel cell vehicles as a "three vertical "Several European countries as well as U.S,Japan,China and others, have recently announced bold plans for the introduction of electric vehicles. These include fiscal incentives, funding research on batteries and electric vehicles and plans for the deployment of a charging infrastructure. Major cities such as London and Paris have announced electric car-sharing systems, while public administrations and companies using large captive fleets are purchasing electric vehicles.At the same time, utilities, car manufacturers, battery producers and academics are joining forces on initiatives such as the EURELECTRIC Task Force on Electric Vehicles and EpoSS, the European Technology Platform on Smart Systems Integration. Together with the European Investment Bank the European Commission has launched the European Green Cars Initiative, with EUR 5 billion partly dedicated to the research, development and manufacturing of batteries and electric cars and to demonstration projects.This flurry of activity seems to indicate that the electric car is heading for a major breakthrough at last - but is it here to stay this time? History calls for caution. The production of electric vehicles began as far back as 1838 – 52 years before combustion engine vehicles. However, after 1913 the mass commercialization of the combustion engine led to a rapid decline in electric vehicles. Attempts to reintroduce electric vehicles in past decades have for the most part been unsuccessful and they still represent a very small, niche market.One of the biggest issues facing the potential take-up of electric vehicles is the rate of improvement in the performance of electric vehicle batteries.The biggest drag on electric vehicle performance comes from the lithium-ion battery, which can add another 220 kilograms to the total weight of a car, versus an ICE-powered vehicle.Since most passenger vehicles in China today are driven in urban areas, where shorter distances and slower speeds are the norm, this may not prove to be as vexing an issue as it is in other markets such as the US or Europe, where the average driving distance and top speed are considerably longer and higher. Continued research and development into electric battery technology is generating promising improvements in performance. US-based A123Systems,one of the world's largest producers of high-power lithium-ion batteries, Announced a battery capable of powering a car for 200 kilometersbetween charges. Toshiba recently announced the commercial launch of its Super Charge battery, which can be charged to 90 percent capacity in less than five minutes.Yet today the future looks brighter. A great deal of progress has been made in battery technology and electric vehicles are expected to re-enter the market on a large scale within the next couple of years. Based on a moderate growth scenario, by 2050, electric vehicles could represent more than 60%of new sales and constitute up to 25% of the global car fleet. However, estimates of the extent of future deployment vary greatly, as there is still some uncertainty in relation to the development of technology and future consumer behavior.One of the primary benefits of electric vehicles is, of course, the reduction of Green house gases emitted into the atmosphere. Our calculation of the total carbon abatement potential of alternative power train technologies counted not only the CO2 emissions that vehicles produce, but also emissions produced through out their entire life-cycle, from the CO2 emitted during the generation of electric power through to the transportation of fuel.Over a period of 8 months in 2008, a global McKinsey team studied the passenger vehicle industries in North America, Europe, China, and India. The team examined four power train technology alternatives, chosen on the basis of existing technologies and their near-term commercial feasibility. They contrasted them to conventional internalcombustion engine (ICE) vehicles that run on gasoline or diesel.Full hybrid vehicles: Running primarily on gasoline, full hybrids are powered by a battery during acceleration of the vehicle, but draw most of their power from an internal combustion engine. Full hybrids, equipped with ICE improvement technologies mentioned above, have a life-cycle carbon abatement potential of 56 percent.Compressed natural gas (CNG) vehicles: CNG vehicles are normally perceived to be a source of clean energy, but their life cycle carbon abatement potential depends wholly on the source of the gas一the greater the distance the gas needs to be transported, the higher this power train's "well-to-tank" emissions. CNG cars rank close to hybrids in their life-cycle carbon abatement potential at 55 percent, assuming the gas comes from local sources.Electric vehicles: Electric vehicles include plug-in hybrid vehicles (PHEV) and battery electric vehicles (BEV). Compared with full hybrids, plug-in hybrid vehicles contain a much bigger battery that can power the vehicle for a longer distance without the aid of an internal combustion engine, can be recharged by plugging them into standard electric sockets, and derive a smaller proportion of their propulsion from the internal combustion engine. Can be recharged by plugging them into standard electric sockets, and derive a smaller proportion of their propulsion from the internal combustion engine. Battery electric vehicles run solely on battery power without the aid of any internalcombustion mechanism. Given reliance on coal-fired plants for electricity.electric vehicles today only have a 19 percent carbon abatement potential over current internal combustion engine technologies; however, this can be increased to as much as 49 percent if diversifies its energy mix towards alternative energy sources for its supply of electric power.Electric vehicles have zero tailpipe emissions, but there are, of course, emissions involved in the production of electricity. As an example,with no concerted action to adopt new power train technologies, the level ofCO2 emissions from passenger cars in China could reach nearly 1.2 billion tons in 2030. However, our research showed that by adopting a mix of various alternative power train technologies, China could cut emissions from passenger vehicles by up to 45 percent. Relative to other power train technologies, electric vehicles demonstrate a some what weaker carbon abatement potential. While full hybrid cars have an abatement potential of 56 percent, electric vehicles' potential stands at 19 percent. This can be explained by the fact that China still relies on coal-fired plants for as much as 85 percent of its electricity supply. This can be explained by the fact that China still relies on coal-fired plants for as much as 85 percent of its electricity supply.It also can blossom into another electric car benefits of electricvehicles is th e “displacement “of harmful air pollutants from urban to rural areas, where population exposure is lower. Noise levels are also lower, particularly in urban driving conditions.Another major advantage of electric vehicles is their energy efficiency. With a tank-to-wheel efficiency in the range of 60 to 80 %, they outperform conventional cars four-fold. Generally, electric vehicles show greatest energy savings at low speeds and in situations involving frequently-changing driving dynamics, which is another reason why cities are a prime target market.Electric vehicles will also create opportunities for software developers. Electric vehicles require an electronic interface that informs the driver of the status of the car's vital statistics, from fuel and battery usage, to split-second updates in GPS navigation systems. Venture-backed start-up Better Place is developing a comprehensive information management system it calls AutOS.that will, among other things, inform the driver of the nearest battery-charging stations.While other technologies such as fuel cells hold great promise in reducing CO2 emissions, its commercial application remains years away. Investing in electric vehicles, however, does not mean Chinese OEMs and suppliers should stop their research into other technologies. Rather, they should maintain a balanced technology portfolio, with electric vehicles being a near-term solution, while viewing other technologiessuch as fuel cells as a potential long-term solution that could yield returns once the technology becomes commercially viable.Thanks to their energy efficiency, and assuming that electricity generation will be even greener in the future, electric vehicles could contribute to a considerable reduction in greenhouse gases. Given the ongoing debate on climate change, this could prove to be an important factor. Indeed, transport is responsible for more than a fifth of the EU’s greenhouse gas emissions and it is the only sector with growing emissions. While the improvement of internal combustion engines still offers considerable potential for reducing emissions per kilometer driven, reductions in greenhouse gas emissions over and above 50 % will require new technological solutions, such as the electric vehicle.Compared to conventional vehicles, and based on the current average European electricity supply, electric vehicles have 50 % less emissions. Further benefits can be achieved if the carbon intensity of power generation continues to decrease with further greener and renewable energy sources.The electric car finally seems to be on the verge of breaking through, offering significant environmental benefits, especially in urban areas. There are, however, still some obstacles related to green electricity supply, the as yet expensive battery technology, the limited driving range and the need for a dense network of electric chargingfacilities. To overcome these obstacles, innovative business models are being developed to help transform automotive transport.电动车:正在进行的绿色交通革命?随着世界上持续的能源危机,战争和石油消费以及汽车数量的增加,能源日益减少,有一天它会消失得无影无踪。

英文原文:The History of the Electric CarIntroduced more than 100 years ago, electric cars are seeing a rise in popularity today for many of the same reasons they were first popular.Whether it’s a hybrid, plug-in hybrid or all-electric, the demand for electric drive vehicles will continue to climb as prices drop and consumers look for ways to save money at the pump. Currently more than 3 percent of new vehicle sales, electric vehicles sales could to grow to nearly 7 percent -- or 6.6 million per year -- worldwide by 2020, according to a report by Navigant Research.With this growing interest in electric vehicles, we are taking a look at where this technology has been and where it’s going. Travel back in time with us as we explore the history of the electric car.THE BIRTH OF THE ELECTRIC VEHICLEIt’s hard to pinpoint the invention of the electric car to one inventor or country. Instead it was a series of breakthroughs -- from the battery to the electric motor -- in the 1800s that led to the first electric vehicle on the road.In the early part of the century, innovators in Hungary, the Netherlands and the United States -- including a blacksmith from Vermont -- began toying with the concept of a battery-powered vehicle and created some of the first small-scale electric cars. And while Robert Anderson, a British inventor, developed the first crude electric carriage around this same time, it wasn’t until the second half of the 19th century that French and English inventors built some of the first practical electric cars.Here in the U.S., the first successful electric car made its debut around 1890 thanks to William Morrison, a chemist who lived in Des Moines, Iowa. His six-passenger vehicle capable of a top speed of 14 miles per hour was little more than an electrified wagon, but it helped spark interest in electric vehicles.Over the next few years, electric vehicles from different automakers began popping up across the U.S. New York City even had a fleet of more than 60 electric taxis. By 1900, electric cars were at their heyday, accounting for around a third of all vehicles on the road. During the next 10 years, they continued to show strong sales.THE EARLY RISE AND FALL OF THE ELECTRIC CARTo understand the popularity of electric vehicles circa 1900, it is also important to understand the development of the personal vehicle and the other options available. At the turn of the 20th century, the horse was still the primary mode of transportation. But as Americans became more prosperous, they turned to the newly invented motor vehicle -- available in steam, gasoline or electric versions -- to get around.Steam was a tried and true energy source, having proved reliable for powering factories and trains. Some of the first self-propelled vehicles in the late 1700s relied on steam; yet it took until the 1870s for the technology to take hold in cars. Part of this is because steam wasn’t very practical for personal vehicles. Steam vehicles required long startup times -- sometimes up to 45 minutes in the cold -- and would need to be refilled with water, limiting their range.As electric vehicles came onto the market, so did a new type of vehicle -- the gasoline-powered car -- thanks to improvements to the internal combustion engine in th e 1800s. While gasoline cars had promise, they weren’t without their faults. They required a lot of manual effort to drive -- changing gears was no easy task and they needed to be started with a hand crank, making them difficult for some to operate. They were also noisy, and their exhaust was unpleasant.Electric cars didn’t have any of the issues associated with steam or gasoline. They were quiet, easy to drive and didn’t emit a smelly pollutant like the other cars of the time. Electric cars quickly became popular with urban residents -- especially women. They were perfect for short trips around the city, and poor road conditions outside cities meant few cars of any type could venture farther. As more people gained access toelectricity in the 1910s, it became easier to charge electric cars, adding to their popularity with all walks of life (including some of the “best known and prominent makers of gasoline cars” as a 1911 New York Times article pointed out).Many innovators at the time took note o f the electric vehicle’s high demand, exploring ways to improve the technology. For example, Ferdinand Porsche, founder of the sports car company by the same name, developed an electric car called the P1 in 1898. Around the same time, he created the world’s first hybrid electric car -- a vehicle that is powered by electricity and a gas engine. Thomas Edison, one of the world’s most prolific inventors, thought electric vehicles were the superior technology and worked to build a better electric vehicle battery. Even Henry Ford, who was friends with Edison, partnered with Edison to explore options for a low-cost electric car in 1914, according to Wired.Yet, it was Henry Ford’s mass-produced Model T that dealt a blow to the electric car. Introduced in 1908, the Model T made gasoline-powered cars widely available and affordable. By 1912, the gasoline car cost only $650, while an electric roadster sold for $1,750. That same year, Charles Kettering introduced the electric starter, eliminating the need for the hand crank and giving rise to more gasoline-powered vehicle sales.Other developments also contributed to the decline of the electric vehicle. By the 1920s, the U.S. had a better system of roads connecting cities, and Americans wanted to get out and explore. With the discovery of Texas crude oil, gas became cheap and readily available for rural Americans, and filling stations began popping up across the country. In comparison, very few Americans outside of cities had electricity at that time. In the end, electric vehicles all but disappeared by 1935.GAS SHORTAGES SPARK INTEREST IN ELECTRIC VEHICLES Over the next 30 years or so, electric vehicles entered a sort of dark ages with little advancement in the technology. Cheap, abundant gasoline and continued improvement in the internal combustion engine hampered demand for alternative fuel vehicles.Fast forward to the late 1960s and early 1970s. Soaring oil prices and gasoline shortages -- peaking with the 1973 Arab Oil Embargo -- created a growing interest in lowering the U.S.’s dependence on foreign oil and finding homegrown sources of fuel. Congress took note and passed the Electric and Hybrid Vehicle Research, Development, and Demonstration Act of 1976, authorizing the Energy Department to support research and development in electric and hybrid vehicles.Around this same time, many big and small automakers began exploring options for alternative fuel vehicles, including electric cars. For example, General Motors developed a prototype for an urban electric car that it displayed at the Environmental Protection Agency’s First Symposium on Low Pollution Power Systems Development in 1973, and the American Motor Company produced electric delivery jeeps that the United States Postal Service used in a 1975 test program. Even NASA helped raise the profile of the electric vehicle when its electric Lunar rover became the first manned vehicle to drive on the moon in 1971.Yet, the vehicles developed and produced in the 1970s still suffered from drawbacks compared to gasoline-powered cars. Electric vehicles during this time had limited performance -- usually topping at speeds of 45 miles per hour -- and their typical range was limited to 40 miles before needing to be recharged.ENVIRONMENTAL CONCERN DRIVES ELECTRIC VEHICLES FORWARD Fast forward again -- this time to the 1990s. In the 20 years since the long gas lines of the 1970s, interest in electric vehicles had mostly died down. But new federal and state regulations begin to change things. The passage of the 1990 Clean Air Act Amendment and the 1992 Energy Policy Act -- plus new transportation emissions regulations issued by the California Air Resources Board -- helped create a renewed interest in electric vehicles in the U.S.During this time, automakers began modifying some of their popular vehicle modelsinto electric vehicles. This meant that electric vehicles now achieved speeds and performance much closer to gasoline-powered vehicles, and many of them had a range of 60 miles.One of the most well-known electric cars during this time was GM’s EV1, a car that was heavily featured in the 2006 documentary Who Killed the Electric Car? Instead of modifying an existing vehicle, GM designed and developed the EV1 from the ground up. With a range of 80 miles and the ability to accelerate from 0 to 50 miles per hour in just seven seconds, the EV1 quickly gained a cult following. But because of high production costs, the EV1 was never commercially viable, and GM discontinued it in 2001.With a booming economy, a growing middle class and low gas prices in the late 1990s, many consumers didn’t worry about fuel-efficient vehicles. Even though there wasn’t much public attention to electric vehicles at this time, behind the scenes, scientists and engineers -- supported by the Energy Department -- were working to improve electric vehicle technology, including batteries.A NEW BEGINNING FOR ELECTRIC CARSWhile all the starts and stops of the electric vehicle industry in the second half of the 20th century helped show the world the promise of the technology, the true revival of the electric vehicle didn’t happen until around the start of the 21st century. Depending on whom you ask, it was one of two events that sparked the interest we see today in electric vehicles.The first turning point many have suggested was the introduction of the Toyota Prius. Released in Japan in 1997, the Prius became the world’s first mass-produced hybrid electric vehicle. In 2000, the Prius was released worldwide, and it became an instant success with celebrities, helping to raise the profile of the car. To make the Prius a reality, Toyota used a nickel metal hydride battery -- a technology that was supported by the Energy Department’s research. Since then, rising gasoline p rices and growingconcern about carbon pollution have helped make the Prius the best-selling hybrid worldwide during the past decade.(Historical footnote: Before the Prius could be introduced in the U.S., Honda released the Insight hybrid in 1999, making it the first hybrid sold in the U.S. since the early 1900s.)The other event that helped reshape electric vehicles was the announcement in 2006 that a small Silicon Valley startup, Tesla Motors, would start producing a luxury electric sports car that could go more than 200 miles on a single charge. In 2010, Tesla received at $465 million loan from the Department of Energy’s Loan Programs Office -- a loan that Tesla repaid a full nine years early -- to establish a manufacturing facility in California. In the short time since then, Tesla has won wide acclaim for its cars and has become the largest auto industry employer in California.Tesla’s announcement and subsequent success spurred many big automakers to accelerate work on their own electric vehicles. In late 2010, the Chevy V olt and the Nissan LEAF were released in the U.S. market. The first commercially available plug-in hybrid, the V olt has a gasoline engine that supplements its electric drive once the battery is depleted, allowing consumers to drive on electric for most trips and gasoline to extend the vehicle’s range. In comparison, the LEAF is an all-electric vehicle (often called a battery-electric vehicle, an electric vehicle or just an EV for short), meaning it is only powered by an electric motor.Over the next few years, other automakers began rolling out electric vehicles in the U.S.; yet, consumers were still faced with one of the early problems of the electric vehicle -- where to charge their vehicles on the go. Through the Recovery Act, the Energy Department invested more than $115 million to help build a nation-wide charging infrastructure, installing more than 18,000 residential, commercial and public chargers across the country. Automakers and other private businesses also installed their own chargers at key locations in the U.S., bringing today’s total of public electricvehicle chargers to more than 8,000 different locations with more than 20,000 charging outlets.At the same time, new battery technology -- supported by the Energy Department’s Vehicle Technologies Office -- began hitting the market, helping to improve a plug-in electric vehicle’s range. In addition to the battery technology in nearly all of the first generation hybrids, the Department’s research also helpe d develop the lithium-ion battery technology used in the V olt. More recently, the Department’s investment in battery research and development has helped cut electric vehicle battery costs by 50 percent in the last four years, while simultaneously improving the vehicle batteries' performance (meaning their power, energy and durability). This in turn has helped lower the costs of electric vehicles, making them more affordable for consumers.Consumers now have more choices than ever when it comes to buying an electric vehicle. Today, there are 23 plug-in electric and 36 hybrid models available in a variety of sizes -- from the two-passenger Smart ED to the midsized Ford C-Max Energi to the BMW i3 luxury SUV. As gasoline prices continue to rise and the prices on electric vehicles continue to drop, electric vehicles are gaining in popularity -- with more than 234,000 plug-in electric vehicles and 3.3 million hybrids on the road in the U.S. today.THE FUTURE OF ELECTRIC CARSIt’s hard to tell where the future will take electric vehicles, but it’s clear they hold a lot of potential for creating a more sustainable future. If we transitioned all the light-duty vehicles in the U.S. to hybrids or plug-in electric vehicles using our current technology mix, we could reduce our dependence on foreign oil by 30-60 percent, while lowering the carbon pollution from the transportation sector by as much as 20 percent.To help reach these emissions savings, in 2012 President Obama launched the EV Everywhere Grand Challenge -- an Energy Department initiative that brings together America’s best and brightest scientists, engineers and businesses to make plug-in electric vehicles more as affordable as today’s gasoline-powered vehicles by 2022. Onthe battery front, the Depar tment’s Joint Center for Energy Storage Research at Argonne National Laboratory is working to overcome the biggest scientific and technical barriers that prevent large-scale improvements of batteries.And the Department’s Advanced Research Projects Age ncy-Energy (ARPA-E) is advancing game-changing technologies that could alter how we think of electric vehicles. From investing in new types of batteries that could go further on a single charge to cost-effective alternatives to materials critical to electric motors, ARPA-E’s projects could transform electric vehicles.In the end, only time will tell what road electric vehicles will take in the future.中文译文:电动车的历史介绍了100多年前,电动汽车的第一次流行在今天看来有越来越多的相同的原因。

There are more than 40 states in accordance with the policy of the federal government, law, drawn up on the mandatory state and encourage the use of clean fuel CNG vehicles, such as policies and measures to promote the CNG filling station development and construction of motor vehicles. At present, more than 40 countries around the world have a gas car, mainly in the rich natural gas resources in Italy, New Zealand, Argentina, Brazil and other countries and stricter environmental regulations the United States, Japan and other countries.Second, natural gas vehicle (CNG) fuel and other environmental and economic benefits comparedCompressed natural gas vehicles:20MPa compressed natural gas in the car to compressed natural gas cylinders in use by the supply of internal combustion engine after the pressure reducer.To CNG fuel for vehicles compared with gasoline has the following advantages: l, reduce pollution and improve the atmospheric environment: natural gas is a clean energy, with a high calorific value, high efficiency, pollution, etc., the comparison is totally burned, not carbon deposition, CO, NOx and particulate emissions than gasoline, significantly reduced exhaust pollution. Motor vehicle exhaust is the major source of urban air pollution, one of which is carbon monoxide harmful ingredients (C0), hydrocarbons (HC), nitric oxide (N0) and nitrogen dioxide (NO2) and so on. According to the data, the use of gas as a motor fuel and gasoline as fuel can reduce emissions compared to 90% CO, 90% S02, 72% HC, 39% NOx, 24% CO2, non-dust emissions, to improve the urban environment has a significant role in .A typical diesel engine and gasoline engine emissions and gas machine is shown in table l.2, CNG vehicle for a higher securityCompared with gasoline, compressed natural gas is a relatively safe fuel. (1) natural gas explosion limit is 5% higher than gasoline (lower explosion limit for the l%) high, methane ignition for 645 ℃, ignition than gasoline high 218 ℃, compared to not ignite. Low density of methane, the relative density of about 0.55, resulting in leakage of gas will soon be distributed in the air, in the case of the natural environment it is difficult to form a hot combustion conditions, once the compressed natural gas from the tank or pipe leaks, leak immediately surrounding the formation of low-temperature zone, so that the difficulties of natural gas combustion. Therefore is a fairly safe CNG motor fuel. Natural gas and fuel properties of gasoline is shown in table 2(2) Department of natural gas vehicle cylinder pressure vessel(20MPa), its materials and manufacture and testing in order that all States have strict control, in China there are "compressed natural gas cylinder vehicle standards)) (GBl7258-1998).Cylinders fitted with explosion-proof facilities, pressure reducer, valves and other equipment, strict standards high, and gas supply system is safe and reliable and will not tip over due to vehicle collision or cause fire or explosion, and the petrol tank of motor vehicles department of non-pressure vessels, fire easily after the explosion.3, will help ease the contradiction between energy supply and demand tension. China's economy is in a stage of rapid development, the number of vehicles to 1 million / year above the rate of increase of a substantial increase in gasoline demand of resources, our need to import large quantities of crude oil per year, refined oil and LPG. Optimize the use of gas carsMotor fuel supply structure has changed only motor fuel gasoline, diesel patterns, not only eased the problem of shortage of petrol and transport services to meet the needs of the development.4, extend engine life.
