The long-term prospects for the U.K. economy are inevitably uncertain, and the most recent Department of Energy long-term projection puts forward three scenarios for the next 30 years with GDP growth rates of roughly 2.5, 1.5 and 0.5% p.a. The highest value corresponds to slightly less than the 1948 - 72 average, the central value is close to the long-run average over the last 80 years, and the lowest figure is similar to the performance during the current recession since 1973.

Because transportation is such a large contributor to global warming, both globally and in the United States, climate and energy experts say finding clean alternatives to gasoline is also key to replacing fossil fuels and slowing global warming. Just as there is debate and competing research about which type of alternative transportation fuel should be developed to produce electricity, however, there is also competition among possible new transportation fuels. So far, in the United States, significant funding has been put into two transportation technologies—ethanol and hydrogen fuel cells. Many energy commentators say cars powered by electric batteries are the technology closest to mass production capability, however. (more…)

The European Automobile Manufacturers Association (ACEA) has offered, and the European Commission (EC) has accepted, a voluntary commitment to reduce the CO2 emissions from new light-duty passenger vehicles, with firm fleetwide targets of 140 g CO2 /km (B41 mpg for gasoline) by 2008, measured under the new European test cycle (Directives 93/116/EC and 99/100/EC). This represents approximately a 25% reduction from the 1995 average of 187 g/km (B30 mpg) on this cycle. The European cycle is likely to produce lower fuel economy ratings than the U.S. combined urban/ highway cycle, so the ‘‘U.S. equivalent’’ miles per gallon ratings of the year 2008 European fleet will likely be higher than 41 mpg if the targets are met.

The commercialization prospects for fuel cell vehicles depend not only on their performance and cost, but also on how well they can compete with other technology options that address similar market and policy needs. While market forces have not traditionally motivated design change for reasons of environmental performance, customer values and expectations can evolve and such characteristics could grow in importance. However, inherent market conservatism will favor less disruptive ways to address evolving needs, which might be met by improved gasoline and diesel vehicles, including hybrid-electric versions. Yet looking over the long run, particularly the need to substantially reducing greenhouse gas emissions, hydrogen fuel cells may well provide a solution that is superior to other alternatives.

Biofuels are made from living matter, plant or animal, and are strongly favored by agricultural interests because of the large boost they bring to domestic farms. Most U.S. biofuels is made from corn (ethanol) or soybeans (biodiesel), although several unusual fuel sources are emerging, including algae and oil waste from deep-frying of foods. The biofuels industry experienced meteoric growth in 2005, 2006 and early 2007, but then it began to slow because of high feedstock prices. Private investment in biofuels finished off 2007 at $2.1 billion, according to ‘Global Trends in Sustainable Energy’, a report by New Energy Finance and United Nations Environmental program. (more…)

Most alternative fuel vehicles on the road today were originally designed for gasoline, but converted for use with an alternative fuel. Because the petroleum industry has successfully responded to the competitive threats of alternative fuels by developing reformulated gasoline that burn much cleaner, the conversions are typically performed more for economic reasons (when the alternative fuel is less expensive, which has occurred with propane) rather than environmental reasons.

Hydrogen has many applications when it comes to fuel. It can be used both in internal combustion engines and hydrogen fuel cells. Hydrogen engines are using the same principle the same way as gasoline fuels or hydrogen natural gas burned combustion, while the chemical energy of hydrogen used to generate electricity and heat transmission. Since the electrochemical reactions produced more efficient energy compare to the combustion energy, fuel cells are created more efficient fuel compare to internal combustion engines. In the long term it will benefit to the more efficient hydrogen conversion process. (more…)
