China is already making green hydrogen today at USD $2.20-2.40/kg, in Ningxia, using alkaline electrolyzers. This is in line with the cost of blue hydrogen, and getting close to the cost of grey. Mostly what's missing at the moment is economies of scale, which is coming. For example, a facility ten times the size of the Ningxia one goes online in 2023, in Inner Mongolia. Combine this with standard cost reductions in PV and wind, and electrolysis of hydrogen will likely be cheaper than SMR by the end of the decade.
