100 MW Electrolyser in Hamburg



The companies Vattenfall, Shell, Mitsubishi Heavy Industries (MHI) and Hamburg’s municipal heat supplier Hamburg Wärme are planning to build one of the world’s largest electrolysers in the Port of Hamburg to produce green hydrogen. The new electrolyser will have a capacity of 100 megawatts and be built on the site of the former Moorburg coal-fired power plant by 2025. The four companies have now signed a letter of intent for the project. In addition, the future development of the site into a so-called “Green Energy Hub” is also planned.

According to the four partner companies, the energy site offers ideal conditions for further use. It is connected to the national 380,000-volt transmission grid as well as to the 110,000-volt grid of the city of Hamburg. In addition, overseas ships can dock directly at the site and use the quay and port facility as an import terminal. In addition, the city’s gas network company intends to establish a hydrogen network in the port within ten years and is already working on the necessary distribution infrastructure. Numerous potential customers for green hydrogen are located in the vicinity of the site so that the entire hydrogen value chain – from production to storage and transport to concrete application in the various sectors – will be represented locally.
