Green hydrogen is a crucial component in the global effort to decarbonize hard-to-abate sectors, like long-haul transportation, construction, and manufacturing. A process first discovered in the early 19th century may hold the key to scaling its production.

This clean fuel is produced by splitting water molecules using renewable electricity, a process called electrolysis. Unlike traditional hydrogen, which is often produced using fossil fuels, green hydrogen creates no carbon emissions, making it a promising option for industries with ambitious sustainability goals.

The current development of 100 MW-class systems, as demonstrated by projects like the Kawasaki pilot plant, is likely just the beginning. Industry experts anticipate gigawatt-scale plants becoming feasible within the next decade, which would dramatically increase production capacity and potentially drive down costs through economies of scale.
