Flow-through electrodes make hydrogen 50 times faster

Electrolysis, passing a current through water to break it into gaseous hydrogen and oxygen, could be a handy way to store excess energy from wind or solar power. The hydrogen can be stored and used as fuel later, when the ...

Researchers go 'cuckoo' over Antarctic penguin poop

Antarctica's king penguins emit such copious amounts of nitrous oxide, or laughing gas, via their faeces that researchers went a little "cuckoo" studying them, according to a Danish scientific study published Thursday.

Slivers of land could power cheaper, greener nitrogen fertilizers

Nitrogen-based fertilizer contributes to the high yields expected from crops in the developed world, but its high use also damages nearby waters and ecosystems. Conversely, developing countries that most need yield improvements ...

Technique could enable cheaper fertilizer production

Most of the world's fertilizer is produced in large manufacturing plants, which require huge amounts of energy to generate the high temperatures and pressures needed to combine nitrogen and hydrogen into ammonia.

New ethane-munching microbes discovered at hot vents

Researchers from the Max Planck Institute for Marine Microbiology in Bremen have discovered a microbe that feeds on ethane at deep-sea hot vents. With a share of up to 15%, ethane is the second-most common component of natural ...

Water heaters' methane leaks are high, but fixable

Natural gas escapes from water heating systems through leaks and because some is not combusted by the burner. These tiny inefficiencies can add up: The resulting emissions of methane—a powerful greenhouse gas—for water ...
