(PhysOrg.com) -- If hydrogen is to ever to serve as an onboard energy carrier for the transportation industry, a material will be needed that can store large amounts of hydrogen at ambient temperature and pressure.

(PhysOrg.com) -- There are many ways to generate hydrogen, such as water electrolysis and steam reforming of gas, but the hydrogen produced by these methods tends to be combined with other byproduct and residual gases. For this reason, a second step to purify the hydrogen is usually required after it is produced. Now in a new study, scientists have developed a method for generating hydrogen with a purity of more than 99% within a single membrane, eliminating the need for a separate purification step.

There aren't very many hydrogen cars on the road these days, but there might be soon. And when there are, it will be possible to take the dirty water from your toilet and turn it into fuel. Wastewater--the stuff that goes down the toilet when you flush--is often treated and used for everything from creating artificial snow to watering golf courses.

Is hydrogen actually clean, or just clean compared to fossil fuels? Even though it mostly produces water, there are some nasty side effects no one is talking about

Trapping antihydrogen atoms at the European Organization for Nuclear Research (CERN) has become so routine that physicists are confident that they can soon begin experiments on this rare antimatter equivalent of the hydrogen atom, according to researchers at the University of California, Berkeley.

As an eco-fuel, hydrogen has numerous advantages, including clean emissions. Storing hydrogen, however, has been proven difficult and dangerous--until now. The Department of Energy has achieved a nanotech breakthrough that will allow for the safe storage and transport of hydrogen
