The conference news feed carried an item on accelerating green hydrogen production to terawatt scale. The phrase is ambitious: it implies a manufacturing and deployment effort far beyond current electrolyser capacity.
Reaching that scale would require cheaper stacks, faster permitting, abundant renewable electricity, better water management and a supply chain that can deliver components on time. It would also require a market for the hydrogen, whether in industry, transport or power.
The item reflected a shift in the conference conversation from whether electrolysis works to how quickly it can be manufactured and installed.
