Alan Shaw, the chemist and executive who led a six-year effort to turn inedible crops into fuels to displace gasoline, has renounced the industry he helped pioneer and decided the future instead lies with natural gas. …

A pioneering program by one of the world’s largest cities to switch its vehicle fleet to clean fuel has not significantly improved harmful vehicle emissions in more than 5,000 vehicles – and worsened some vehicles’ climate impacts – a new University of British Columbia study finds. The study – which explores the impacts of New [...]

Designs for the Riversimple urban car, capable of a 50mph top speed and a 240 mile range, will be freely available online in a bid to help grow the hydrogen market. A new hydrogen-powered car, whose designs will be “open source” and posted for free use on the web, was unveiled today in London. The [...]

Empa and the Paul Scherrer Institute (PSI) have, together with Bucher Schoerling, Proton Motor, BRUSA Elektronik AG und Messer Schweiz, developed a hydrogen powered municipal street cleaning vehicle which was presented to the public on 14th May 2009 in Basel. The vehicle is named the “Bucher CityCat H2″ and is the first municipal utility vehicle [...]

Natural gas is a mixture of hydrocarbons, primarily methane (CH4) but also containing ethane and propane and other gases such as nitrogen, helium, carbon dioxide, hydrogen sulfide, and water vapor. Natural gas does have a high octane rating and excellent properties for spark-ignited internal combustion engines and is relatively clean burning. It is non-toxic, non-corrosive, [...]

Propane, which is generally known as liquefied petroleum gas (LPG or LP-gas), or AutoGas in Europe, is a three-carbon alkane gas (C3H8). Propane has one of the highest energy densities of all alternative fuels, so propane vehicles can go farther on a tank of fuel. This is one of the reasons that it is used [...]

In 2003, President George Bush, in his State of the Union address, announced a $1.2 billion hydrogen fuel initiative with the express intention to reduce America’s dependence on foreign oil and to provide the fuel we need to reduce gasoline consumption in our vehicles.  That financial commitment enabled scientists to direct more energy into developing [...]
