LCOH considers the average cost of hydrogen weighing in all discounted costs, e.g., the initial investment cost, return on capital, operation cost, electricity cost, maintenance cost, and the cost associated with the disposal of the electrolyzer, all divided by the accumulated sum of the produced hydrogen.
The economic viability of hydrogen production is highly dependent on electricity pricing and carbon taxes. With the current electrolyzer costs, electricity prices need to drop below 22 USD/MWh for green hydrogen production to compete with grey hydrogen produced from natural gas priced at around 20 USD/MWh.
A major goal for electrolyzer providers is to achieve "fossil parity" — meaning the electroyzer can produce green H 2 for the same price as using an SMR with natural gas ("gray" hydrogen).
