Such a lousy EROEI (energy return on energy invested) should immediately disqualify hydrogen from serious energy policy discussions.

Advocates appear to believe that a landslide of money can create a new green fuel industry. But a hydrogen fuel industry, if created, will be small and based entirely on government subsidies, not sound economics.

Extra electricity from renewable energy could be used to split water to obtain hydrogen - but methods to accomplish this are usually prohibitively expensive, need too much power, or draw on catalyst materials that too rapidly...

Future Mars colonists are going to need oxygen, and NASA has a plan to make it. Their Mars 2020 Rover will be equipped with a Mars Oxygen In-Situ Resource Utilization Experiment device, nicknamed MOXIE, which will attempt...

Scientists at the University of Glasgow have made an exciting clean energy production breakthrough: they've discovered a new method for extracting hydrogen from water that is not only safer than current methods, it's also...

When life gives you lemons, make lemonade. Or, if you are really clever, make a clock. The Citrus Clock by the international design studio Anna Gram harnesses the power of the tart fruits to power a timepiece. The clock uses...

Estuaries may be good for more than harboring wildlife and creating beautiful scenery; they could also supply power to the grid, according to researchers at the Dutch Center for Sustainable Water Technology, the University...

As far as sustainable energy systems go, nothing is quite as perfect as a plant: Through photosynthesis, plants create their own energy using only sunlight and water...
