Data item details

Name: Typical structure of the levelised cost of hydrogen for an alkaline electrolyser in Germany using electricity from the grid during the least cost hours – October 2025 (EUR/kg and EUR/MWh)

Source: ACER, using the LCOH calculation tool of the European Hydrogen Observatory and 2024 wholesale day-ahead market data for Germany from ENTSO-E’s transparency platform.

Comment: The default cost and technical assumptions of the LCOH calculation tool for an alkaline electrolyser were used for the calculations. Grid fees were set to zero. A theoretically optimal operation of the electrolyser is assumed with a perfect foresight of the market prices leading to operation during the less expensive hours of the year for each bucket of operating hours. Day-ahead wholesale electricity prices are based on ENTSO-E’s Transparency Platform.
