Green Hydrogen Could Fill Big Gaps in Renewable Energy

When hydrogen burns, the only by-product is water—which is why hydrogen has been an alluring zero-carbon energy source for decades. Yet the traditional process for producing hydrogen, in which fossil fuels are exposed to steam, is not even remotely zero-carbon. Hydrogen produced this way is called gray hydrogen; if the CO2 is captured and sequestered, it is called blue hydrogen.

Green hydrogen is different. It is produced through electrolysis, in which machines split water into hydrogen and oxygen, with no other by-products. Historically, electrolysis required so much electricity that it made little sense to produce hydrogen that way. The situation is changing for two reasons. First,…

‘Green hydrogen’ from renewables could become cheapest ‘transformative fuel’ within a decade

Energy analysts said it suggested green hydrogen was likely to leapfrog hydrogen made with gas and coal as the most cost-effective form of the energy before the end of the decade, and by the time an industry could be developed at scale.
