cleantechnica.com — Hydrogen cars may be feasible sooner than previously thought thanks to the efforts of a research team at the University of Crete in Greece. The scientists have developed a hydrogen storage model that can store up to 41 grams of hydrogen per liter? almost matching the US Department of Energy?s target of 45 grams per liter.

Yes, he probably COULD say something like that if we weren't all being monitored by the Bush administration.Now with my tin foil hat on, I am able to say whatever I want!Poopy Pants!

While it is true that it takes more energy to produce hydrogen fuel than it generates, keep in mind that we could develop the process to be more cost-efficient. For example it could harness the energy from renewable sources (solar energy). Can you say solar + electrolysis plants?As for the platinum... well, there are always alternatives. This is just a beginning.

Electrolysis is nowhere near as inefficient as mystlyfe thinks. Theoretically, it can reach arbitrarily close to 100% thermodynamic efficiency because there is no need for heat transfer in the process.Hydrolysis still isn't an interesting way to produce hydrogen though. One method that's being researched more is producing a catalyst, which when submerged in water will cleave water into hydrogen with energy from sunlight. Which is potentially much easier and cheaper than solar cells + electrolysis.Such catalysts already exist. It's a matter of improving on them.

Hey I know a great hydrogen binding / storage medium - CARBON! These fancy metals and nanotube graphene sheets still don't meet the energy storage density of a carbon backbone surrounded by hydrogen atoms, i.e. GASOLINE. Hydrogren has a very high gravimetric energy density (energy per weight) but has a very low volumetric energy density (energy per volume) so while your tank of hydrogen will weigh 1/3 your tank of gasoline, it will be 3 times larger (assuming it's liquid nitrogen, which boils off, and must be cooled) There is more hydrogen in a gallon of gasoline then there is hydrogen in a gallon of liquid hydrogen! All of these hydrogen binding contests are just a waste of resources, scammers jumping on alternative energy bandwagons, we should be looking at hydrocarbon based fuel cells and transition to using carbon as a temporary storage medium for hydrogen thus we can utilize the same infrastructure. These best solution is the lightest safe liquid hydrocarbon, either liquid propane or methanol. We all ready have Direct Methanol Fuel cells which are cost effective and take 30 seconds to warm up.
