Part of the Hamburg Green Hydrogen Hub (HGHH), the plant is being developed by Luxcara and Hamburger Energiewerke, with Kraftanlagen Energies & Services serving as EPC contractor.

Using a PEM electrolyser provided by Siemens Energy, the system is expected to produce around 10,000 tonnes of green hydrogen per year once operational in 2027.

The produced volumes will be supplied to industrial users and the Port of Hamburg, while the plant will also feed hydrogen into the regional HH-WIN hydrogen network and a future truck loading station.

The initiative received federal and state funding approval in 2024 as part of Hamburg’s wider hydrogen strategy.

The old Moorburg coal plant has been partly demolished to make way for the start of construction. Electrolyser foundations are currently being laid.

Ground preparation works included installing 906 gravel vibro-compaction columns to stabilise the 16,000m² site.

“When politics, industry, and institutional investors work together reliably, a former coal-fired power plant can be transformed into a competitive, climate-neutral industrial site for Hamburg and far beyond,” explained Alexandra Bernstorff, Managing Partner at Luxcara.

“This requires stable framework conditions and functioning markets so that projects are not just announced but actually built, as is the case with our HGHH project.”

The company plans to finish the building for the electrolyser and compressors by mid-2026.
