- $500-1000/kW [1]
- MIT CEEPR report 2023 - [2]. Has author emails.
- Cost of alkaline, PEM, and oxide Fuel to Gas - [3]. From Guntherglenk.com. Prediction is $1.6/kg by 2030. DOE target is $1/kg - [4]
- 15% cost decrease for doubling of electrolyzer capacity
Electrolyzer System Cost
- System cost: [5], x axis is kW installed capacity:
- 20 year lifetime of electrolyzer
- 3.6 cent electricity cost for wholesale electricity.
Hydrogen Production Cost
Take a kg - which is a gasoline gallon equivalent.- Hydrogen production cost involves 70-90% electricity cost. Result is the following cost per kg hydrogen:
- Thus, look at 20 cent/kw PV panels. 30 year life. $200 cost for 65700 kWhrs. This is 0.3 cents/kWhr - 10x lower than the electricity cost in the study.
- Thus, total Levelized Cost is (fixed + capacity) of 40 cents + 15 cents for variable costs (electricity) = 65 cents/kg.
