“Further reductions in electrolyzer and renewable energy costs will bring the costs of producing green hydrogen below $1.50/kg by 2030. Production costs of this magnitude are highly competitive. In the long term, the cost of green hydrogen production may reach $1/kg or below by 2050. This outcome can occur if electrolyzer costs drop further to $400 per kilowatt, with renewable energy costs falling below $10/MWh.”
