  • $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:

Learning curve indicates 16% cost reduction per capacity doubling. X axis is in kW installed capacity.

    • 20 year lifetime of electrolyzer
    • 3.6 cent electricity cost for wholesale electricity.

Hydrogen Production Cost 2030

  • Check.pngTake a kg - which is a gallon gasoline equivalent.
  • Hydrogen production cost involves 70-90% electricity cost. Result is the following cost per kg hydrogen [6], expected to be reached by 2030:

Cost per kg

  • 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 of 3.6 cents/kWhr in the study.
  • Thus, total Levelized Cost is (fixed + capacity) of 40 cents + 15 cents for variable costs (electricity) = 65 cents/kg - prediction for real cost by 2030.

2024 Cost

  • learning curve from 2020 to 2030 is halving of system cost from $1/W to $0.5/W"

Electrolyzer cost decrease per Watt.

  • This makes cost/kg double the 40 cent fixed cost - 80 cents - plus 15 cents for electricity or 95 cents per kg.
