All cases reflect a $4-5/kg cost for H2 production. The current cases ($5.14 vs. $5.12) and the future cases ($4.23 vs. $4.20) are similar in cost. The H2 cost reduction is greater moving from a current to a future case, compared with moving from a forecourt to a central case. Feedstock costs (electricity expenditures) are 65-80% of total costs.
Electrolysers are a critical technology for the production of low-emission hydrogen from renewable or nuclear electricity.
