Mammoet starts work on the construction of a new combined cycle gas turbine power plant for the future use of hydrogen

With the construction of a new combined cycle gas turbine (CCGT) power plant in Altbach/Deizisau in Germany, EnBW is paving the way for the future use of low-CO2 or green hydrogen in the 2030s. As a first step, the site's electricity and heat production will be switched from coal to gas starting in 2026. The top priority is the uninterrupted supply to households and industry. To ensure this, it was crucial to find competent and reliable partners.

Mammoet was able to convince with a tailor-made engineering concept and comprehensive studies as well as its proven experience in power plant construction. The team had already demonstrated its expertise in the dismantling of Block 1 of the EnBW Neckarwestheim nuclear power plant.

The service package includes just-in-time delivery, handling and unloading, interim storage and the installation of HRSG modules, generators, turbines and transformers.

Andreas Franzke, Sales Manager & Segment Lead Power at Mammoet in Germany, explains: "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”.

On Mammoet's recommendation, a separate temporary jetty was built so that the power plant's fuel loading point would not be additionally burdened 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. In addition, SPMTs, a customized 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,” says Andreas Franzke.

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