If there is ever going to be a national hydrogen economy, we’re going to need to change a few things. One of them is how we produce hydrogen itself, the vast majority of which comes from fossil fuels. SunGreenH2 brings a nanotech-level advance to green hydrogen production, supercharging electrolysis so orders of magnitude more hydrogen can be cleanly made directly from water.

Hydrogen is in use all over the place, but the lack of a scalable, green option for producing it has slowed its adoption. What’s the point of having a hydrogen battery system for renewables if you have to source that hydrogen from natural gas, oil and coal?
