Electrolyser cost

Get latest insights into electrolyser cost by technology in Europe (EU27, EFTA and UK).

The datastream provides CAPEX (EUR/kW) and OPEX (EUR/kW/year) of an electrolyser system for projects based in Europe. The results are presented for two technologies: alkaline and PEM. The CAPEX are divided in three categories: stack, balance of plant (BoP) and other engineering, procurement, and construction (other EPC).

Reference year is 2023.

Note

The data aim to reflect a project of total size of 20 MWel that is under construction or in an otherwise advanced stage. 

Assumptions

  • The stack cost includes all the electrolysis cells and their respective components.
  • The balance of plant cost includes rectifier, transformer directly connected to the rectifier, gas/liquid separation, water/lye feeding, gas purification, water cooling, water purification, control system, other equipment such as gas container and compressor.
  • The other EPC cost includes equipment installation, civil engineering, project design, procurement, management, product shipping and housing at construction site.
  • Electricity is excluded from the OPEX.
