There are many ways to make hydrogen, but only green hydrogen is climate-neutral—unfortunately, it isn't nearly as cost competitive as other energy sources.
A new proof-of-concept reactor, developed by scientists at Shinshu University in Matsumoto, Japan, aims to split water using photocatalysts and good ole sunlight.
Although the idea needs more time in the oven before being commercially viable, it offers a possible pathway for green hydrogen to be a useful for tool for helping humanity kick its fossil fuel addiction.
Hydrogen fuels come in many colors—each one an indicator of how the fuel was initially created. Blue hydrogen refers to fuel created from steam and capturing the resulting carbon underground, pink hydrogen means nuclear energy powers the electrolysis process, and black and brown carbon (as their name denotes) splits H20 using fossil fuels, which isn’t exactly helpful with the whole cutting emissions thing.
