Mammoet has started work on a combined cycle gas turbine (CCGT) plant in Germany, which will ultimately be capable of being powered by hydrogen.

Mammoet begins construction of CCGT plant for future use of hydrogen

The plant, which is in Altbach/Deizisau and run by EnBW, will initially look to switch the site’s electricity and heat production from coal to gas, starting in 2026.

Mammoet landed the work with a proposal that includes just-in-time delivery, handling and unloading, interim storage and installing heat recovery steam generator modules, generators, turbines and transformers. It also has experience in power plant work, including dismantling Block 1 of the EnBW Neckarwestheim nuclear site.

“A completely new concept has been developed in close cooperation with the client and our project team. This means a secure energy supply, fewer interfaces and smooth processes on the construction site,” said Andreas Franzke, sales manager and segment lead power at Mammoet in Germany.

On Mammoet’s guidance, a separate temporary jetty was built so that the power plant’s fuel loading point would not be additionally hampered by unloading for the construction site. A 1,350-tonne crawler crane will allow all heavy lifting for unloading and installation to be carried out safely and efficiently from one crane location. SPMTs, a customised gantry system and other special equipment will also be used.

“We are very pleased to be involved in this important construction project, which is part of the energy transition in Baden-Württemberg. It is a significant step into the future of using green hydrogen in facilities in Germany and beyond,” added Franzke.

The Mammoet team will work on behalf of the Sener Bonatti joint venture.
