Electrical energy storage (EES) can reduce the installation capacity of electrolyzers owing to their steady and continuous operation. Adiabatic compressed air energy storage (A-CAES) systems can be effectively combined with large scale solid-oxide electrolysis cells (SOEC) for low-cost production of hydrogen.
Underground hydrogen storage in pipes and caverns offers economical storage costs ($1–15 kWh −1) that are 10–100× below the capital cost of energy storage in pumped storage hydropower and vanadium redox flow batteries (supplemental information).
Relevance: Overall Cost of Electrolysis. Precious metal costs at 50,000 kg/day are prohibitive at current loadings. Goal: Reduce by order of magnitude. Operating costs driven by efficiency. Oxygen overpotential and membrane ionic resistance drive 90% of stack efficiency losses. Goal: Increase catalyst activity by 10x.

Although pumped hydro storage (PHS) is a mature and widely used technology for bulk-scale energy storage, it is dependent on geological formations. Compressed air energy storage (CAES) is currently the only alternative commercially mature technology to PHS ( He et al., 2021, Zakeri and Syri, 2015 ).
