On-demand Hydrogen Edges Closer, Could Start a 'Green and Sustainable Energy Era,' Scientists Say

ydrogen could play a key role in cultivating a "green and sustainable" source of energy to power portable fuel cells of the future, researchers say.

Hydrogen is believed to be a feasible alternative to fossil fuels because of its affordability and environmental friendliness. It is found throughout the environment, but producing it involves efficiently separating it from the compounds it is contained it. There are currently a number of ways this can be done, but methods can be slow and expensive.

However, a team of scientists has now said hydrogen fuel could be generated "on-demand" thanks to a separation process structured around the chemical element bismuth, a team of scientists has said.

The findings, from researchers with the Chinese Academy of Sciences and Tsinghua University, are published today in the Journal of Renewable and Sustainable Energy.

Their paper says hydrogen fuel cells converting chemical energy to electrical energy could be used to power "aircraft, vehicles and portable devices." However, that is only possible if cells have a high-quality, stable, hydrogen supply—a problem them attempted to overcome.

Researchers used an alloy, consisting of gallium, indium, tin and bismuth metals, to generate hydrogen by making it come into contact with an aluminum plate immersed in water.

The hydrogen is then connected to a proton exchange membrane fuel cell (PEMFC), which is able to convert the chemical energy into electrical energy.

The research suggested bismuth had a "large effect" on hydrogen generation when compared to an alloy previously tested, which was composed of gallium, indium and tin. The alloy that included bismuth was found to produce a more stable and durable reaction.

Author Jing Liu, a professor at the Chinese Academy of Sciences, said the technique had a higher conversion efficiency when compared with traditional power generation methods.

This would piss off the Muslims.

Yeah, that's the only problem.

Hydrogen isn’t an energy source. There are no hydrogen wells or mines.

It’s an energy storage material, and a very difficult one to work with. The molecule is very small, so it is difficult to make containers with acceptable leakage rates. It causes embrittlement in steel, which is also problematic. And I’m just getting started with the issues with hydrogen.

No sale.

I used to like to make Hydrogen as a kid, one inverted test tube at a time.

Any technological solution, however effective, that doesn’t involve destroying Western civilization would be unacceptable to the global warming cult.

Hydrogen! Awesome idea!

Hydrogen works really well on airships

Come on Freedom. Why hydrogen is....IT BURST INTO FLAMES!!!

Going green causes some issues.

Looks like a 10 year old who flunked English wrote this one.

Another fancy non-oil energy source the leftards can drool on. I swear these clowns want us to go back to living in caves and climbing trees for fruit..

Producing it isn’t the problem. In the nineties we vented enough waste hydrogen into the atmosphere (mostly in the plastics industries) to meet eighty percent of the needs for civilian automotive use.

But transporting it and storing it? A tank to hold enough hydrogen to give a car the same range as the typical gas engine car would need a tank the size of the entire trunk.

[P.O.E.]

We wouldn’t need as much helium. It would certainly add excitment to the blowing-out-candles part of birthday parties.

Remember the Hindenberg. Boom!

Applying a current to water, were we?

I used a red devil lye and aluminum foil. Exothermic, could inflate a balloon.

I'm all for clean, sustainable, inexhaustible energy.

Make it safe, inexpensive, easy-access, reliable and I'm in.

Bad idea.Breaking down water is a recipe for disaster. Water is a finite resource. Once it is gone all life on the planet is done

CO2 is good for life
