Fuel cells and hydrogen economy

Viability of a Hydrogen Fuel Based Economy

Some “alternates within alternates” are studied and possible improvement of our energy policies are explored. The viability of a hydrogen fuel economy is reviewed. Methanol, ethanol or ammonia versus hydrogen is one area of interest. Others include liquid hydrogen versus jet fuels, the use of geothermal, solar, wind or water energy for production of hydrogen gas versus development of deep earth...

Prospects on Fuel Economy Improvements for Hydrogen Powered Vehicles

Fuel cell vehicles are the subject of extensive research and development because of their potential for high efficiency and low emissions. Because fuel cell vehicles remain expensive and the demand for hydrogen is therefore limited, very few fueling stations are being built. To try to accelerate the development of a hydrogen economy, some original equipment manufacturers (OEM) in the automotive...

Beyond Batteries: Portable Hydrogen Fuel Cells

Global Fuel Economy Initiative

The critical distinction between the technical potential to improve fuel economy and how much of that technical potential is realized .. Summary The Global Fuel Economy Initiative was launched in early 2009. It set a target of improving the average fuel economy (in litre/100km terms) for the global vehicle light-duty vehicle fleet by at least 50% by 2050 (50by50). In terms of miles per gallon t...
