Scientists Harvest Hydrogen from Water in Micro-gravity, necessary for Deep-Space Travel



A team of scientists announced they have harvested hydrogen from water in micro-gravity, a proof-of concept test that may one day lead to a way to acquire fuel or other resources during a long-distance, crewed space mission.

Hydrogen could serve as an important fuel for future spaceflight missions. But creating usable hydrogen fuel in microgravity isn’t easy. Without gravity, there’s almost no buoyancy, so the hydrogen bubbles that form in the water create a froth that stays put and stops atoms and ions from moving. The researchers constructed microscopic tower structures in the cell which helped guide and release the bubbles.

While its super useful to be able to harvest hydrogen from liquid water during a deep-space mission, there’s still an issue of where the water is coming from. But we’ve written before that water is one of the main resources that space-mining companies hope to harvest from asteroids.

This was just a first attempt at harvesting hydrogen from water, the International Space Station already has a system that splits carbon dioxide into carbon and oxygen. But this is first to directly split hydrogen from water in micro-gravity conditions.
