Production of green hydrogen to supply up to 40 buses from 2027
Darmstadt. Construction of an innovative hydrogen production plant on the site of the Darmstadt waste-to-energy plant (MHKW) will begin in October 2025. ENTEGA AG has awarded the contract to FEST GmbH . The project is part of the DELTA real-world laboratory and is funded by the German Federal Ministry for Economic Affairs and Energy .
The new plant has a capacity of three megawatts and is scheduled to enter regular operation in the first quarter of 2027. Using green electricity, water will be split into oxygen and hydrogen in the electrolyzer. Approximately 310 tons of green hydrogen will be produced annually—enough to operate approximately 40 buses save up to 4,000 tons of CO₂ annually compared to diesel .
Hydrogen for public transport in southern Hesse
The hydrogen produced is collected on-site via a trailer filling station and then used to public transport companies in the region . The focus is on local public transport, where switching to hydrogen propulsion can make a significant contribution to reducing emissions.
Dr. Marie-Luise Wolff , CEO of ENTEGA AG, emphasizes:
"This project demonstrates once again that ENTEGA is a pioneer of the energy transition. Green hydrogen is becoming increasingly important to achieve climate protection goals. We are pleased that ENTEGA can make an exemplary contribution here."
The waste-to-energy plant is owned by the Southern Hesse Waste Recycling Association (ZAS) , while ENTEGA is responsible for its operation. With the start of plant construction, the hydrogen strategy for the South Hesse region a key milestone.
