EnBW commissions hydrogen-ready power plant in Stuttgart EnBW has officially commissioned one of Germany’ s first hydrogen-ready gas turbine power plants at its Stuttgart-Münster site. The new combined heat and power( CHP) plant will supply the city of Stuttgart with 124 MW of electricity and 370 MW of thermal energy, generated by two 62 MW SGT-800 gas turbines from Siemens Energy.
The Stuttgart-Münster site focuses primarily on waste incineration and operates on the CHP principle to maximize fuel efficiency, supplying both electricity and heat to the district heating network. Until now, three coal-fired boilers provided additional heat during winter when waste incineration output was insufficient. These have now been replaced by the new hydrogen-ready plant.
The existing infrastructure includes coaland waste-fired boilers, steam turbines, and, since April 2024, a large heat pump contributing up to 24 MW of thermal energy. The new plant, also equipped with waste heat and hot water boilers, serves both base and peak load demand.
Following around five years of planning and construction, and after successful trials, the plant will soon enter full commercial operation. The older coal and fuel oil units will be decommissioned by spring 2026 – an important step towards Stuttgart’ s climate goal of net-zero emissions by 2035.
Cornerstone laid for green hydrogen production plant in Salzgitter On 12 February 2025, the cornerstone was laid at the Salzgitter Flachstahl site in Salzgitter, Germany, for one of Europe’ s largest green hydrogen production plants. Beginning in 2026, the plant will produce approximately 9,000 tons of green hydrogen per year for use in carbon-reduced steel production.
This milestone marks the industrial adoption of hydrogen in SALCOS ® – Salzgitter Low CO 2
Steelmaking, which aims to achieve virtually carbon-free steel production. The 100 MW electrolysis plant will be supplied on an EPC basis by ANDRITZ, utilizing HydrogenPro’ s pressurized alkaline electrolysis technology.
SALCOS ® is being implemented in phases and consists of a direct reduction plant, an electric arc furnace( both already under construction), and the 100 MW electrolysis plant for hydrogen production. Salzgitter Flachstahl GmbH plans to launch products from this new process as early as 2026. The full conversion to near-carbon-free steel production at the Salzgitter facility is scheduled for completion by 2033.
Gerd Baresch, Managing Director of the Technical Division of Salzgitter Flachstahl GmbH, said:“ Today’ s cornerstone laying represents a further major step in our SALCOS ® program. This shows that the transformation of our company to low-carbon steel production is progressing on schedule. With this system for on-site hydrogen production, we are fulfilling our side of the bargain. The onus is now on governments to create suitable framework conditions for green production. The priorities here are competitive grid costs and a committed incentivization for the promotion of the hydrogen economy.”
