Hydrogen fuel promises to be a clean and abundant source of energy in the future – as long as scientists can figure out ways to produce it practically and cheaply, and without fossil fuels.

A new study provides us with another promising step in that direction.

Scientists have described a relatively simple method involving aluminum nanoparticles that are able to strip the oxygen from water molecules and leave hydrogen gas.

The process yields large amounts of hydrogen, and it all works at room temperature.

That removes one of the big barriers to hydrogen fuel production: the large amounts of power required to produce it using existing methods.

This technique works with any kind of water, too, including wastewater and ocean water.

"We don't need any energy input, and it bubbles hydrogen like crazy," says materials scientist Scott Oliver from the University of California, Santa Cruz (UCSC).
