catalystcoop, On the potential for green H2 cost reductions through experience:
"electrolyzers account for only around one third of the cost of green hydrogen. The rest is driven either by the cost of green electricity – already far down its own experience curve – or by the cost of heavy engineering components – stuff like compressors, tanks, valves, pipes, power supplies and site infrastructure, which are not about to fall off a cliff."
