This study concludes that introducing hydrogen into the energy system would, theoretically, reduce the total EU oil consumption by vehicles on the road by 40%, and by 2050. Also, on releasing the study results, the EU approved funding for a joint technology initiative to develop fuel cell and hydrogen technology. This recognition of hydrogen by the EU raises the possibility that hydrogen could realistically be used in future green solutions.

I'm going to make a prediction today: you will never drive a hydrogen fueled car. Although hydrogen does indeed have some benefits in certain applications, it's my task today to separate the reality of useful fuel cells from the hydrogen hype. That may seem like a bold statement to you now, but by the end of this article, you'll understand why.

Hydrogen is a better source of energy than you think, according to Fujitsu. The Japanese electronics giant inaugurated a 200-kilowatt hydrogen fuel cell from UTC on Friday that will provide electricity as well as heat to the buildings on its campus here. The fuel cell--which sits in the parking lot and looks like a pair of giant green dumpsters--provides two types of energy to the facility. First, a unit heats methane with steam to create hydrogen. The hydrogen is passed through a proton exchange membrane (PEM). The electricity produced by the reaction with the PEM runs lights, computers and other equipment

The marketers out there are selling on-board hydrogen generators which are claimed to provide enough hydrogen to reduce gas consumption by 30-40 percent or more. Is this plausible? Not even close.

"You can use this calculator to obtain the heating value of a given mass or volume of hydrogen or other fuels, or to calculate the mass or volume given a certain heating value. Choose whether you want to convert to heating value or to mass/volume, and then choose the fuel type. Then enter the value you want to convert and its units, and click Convert to initiate the conversion."

An ancient organism from the pit of a collapsed volcano may hold the key to tomorrow's hydrogen economy. Scientists from across the world have formed a team to unlock the process refined by a billions-year old archaea. The U.S. Department of Energy Joint Genome Institute will expedite the research by sequencing the hydrogen-producing organism for comparative genomics.

A new process for using aluminum alloys to generate hydrogen from water could make fuel-cell vehicles more practical,

A hydrogen refuelling station which could be installed in the home as an alternative to visiting a petrol station has been unveiled. Users will need a hydrogen-powered car to go with it although the system can also be used for heating and cooking. Hydrogen has long been touted as an alternative energy source to carbon-hungry fossil fuels.

As fuel cell technologies are developed, hydrogen-powered vehicles are receiving more interest. The hydrogen economy, particularly hydrogen-powered vehicle penetration into the Korean transportation market, is studied in this paper. Market share was predicted using the currently available data. The results showed that the hydrogen era will not be as bright as predicted by many people. The main barrier is the fuel cell cost.

A recent study by Logan group at Penn State University also demonstrated similar findings in that the energy contained in hydrogen gas not only can offset the energy used for the desalination process but has surplus that can be used for downstream processing.

Several years ago even the mobile phones were very expensive, not to mention computers and airplane flights.

The example of mobile phones is of little relevance here, because cost reduction is driven by the scaling laws of microelectronics. However, the reducing cost of flights - in a way the ultimate energy application - offer a good benchmark. What will happen to flights though if commodity and energy prices go up in the long run?

UK scientists have made hydrogen from water in a simple experiment on a lab bench. Fraser Armstrong, at the University of Oxford, and colleagues attached an enzyme and a light-harvesting dye to titanium dioxide particles to make a hydrogen-producing system powered by sunlight.

University Park, Pa. -- A greener, less expensive method to produce hydrogen for fuel may eventually be possible with the help of water, solar energy and nanotube diodes that use the entire spectrum of the sun's energy, according to Penn State researchers. "Other researchers have developed ways to produce hydrogen with mind-boggling efficiency, but their approaches are very high cost," says Craig A. Grimes, professor of electrical engineering. "We are working toward something that is cost effective."

Another advance on the solar energy front. The article itself summarises the importance of this article "while we do not pretend to understand the nitty gritty of dye usage and other such nonsense, we do know that such a system could eventually attain 15% or so efficiency, providing a nice and clean way to gather power for that fuel cell car of the future".

The Commission is also more keen on electric than hydrogen cars...
