Production of green hydrogen in Lubmin

The new German green energy company HH2E is one of the first companies in the country to produce hydrogen from renewable energies on a large scale. The hydrogen specialist is currently planning to build a large-scale electrolysis plant at the Lubmin energy site in Mecklenburg-Western Pomerania and wants to start producing green hydrogen there from 2026. HH2E is also relying on Aerzen's technologies and expertise. The delivery of three VRW 536M units was agreed for the plant on the Baltic coast. The partnership is to be intensified in the long term.

As a strong partner of the process gas industry, Aerzen is known for its high level of technology and solution expertise and is considered one of the most competent providers of technical solutions with the highest level of efficiency, reliability and cost-effectiveness. The hydrogen industry also relies on Aerzen's know-how and experience - as does the Hamburg company HH2E. Aerzen and HH2E have now decided to work together and are thus jointly driving forward the energy transition.

HH2E is driving the hydrogen transition

HH2E produces green hydrogen on an industrial scale using excess electricity from wind and solar energy and plans to install production plants in Germany with a total capacity of at least 4 GW by 2030. A plant is currently under construction in Lubmin. It uses the extensive energy infrastructure of the largest energy and industrial site in Mecklenburg-Western Pomerania and is designed for an initial capacity of 100 MW by 2026. This will enable it to produce around 6,000 tonnes (over 200,000 MWh) of green hydrogen annually. By 2030, the capacity is to be scaled to over 1 GW, which corresponds to an annual production of more than 60,000 tonnes of green hydrogen.

Aerzen supplies three VRW 536M for the hydrogen factory in Lubmin

For the hydrogen factory in Lubmin, HH2E and Aerzen have agreed to supply three VRW 536M units with a volume flow of approx. 4,700 m³/h each and a final pressure of 8.0 bar (a) each for an order value in the upper seven-digit range. The Aerzen VRW 536M was specially developed for the efficient and safe compression of hydrogen and combines the advantages of an oil-free compressor (no contamination of the medium) with a high pressure ratio (max. 10 bar (a)) and a high level of efficiency even with light gases (hydrogen/helium).

The explosion-proof unit offers a large control range and can therefore optimally handle the fluctuations that typically occur when using renewable energies. As a screw compressor, the VRW 536M can also process larger volume flows of up to 6,000 Nm³/h, making it the perfect link between the electrolyzer and high-pressure compressors. By pre-compressing (booster) the large H2 volume flows to higher intermediate pressures, the main compressors (piston compressors) can be made significantly smaller and cheaper. This enables significant cost savings.

Aerzen and HH2E are planning a long-term collaboration

"HH2E's projects are groundbreaking in green hydrogen production. We are pleased to be working with HH2E to make a contribution to the hydrogen transition and decarbonization of industry. The VRW 536M enables the compression of saturated electrolysis hydrogen with previously unattained efficiency and differential pressure, making it an important building block for the hydrogen transition," explains Christian Meyer from Aerzen.

Karsten Kinzig, Head of Procurement at HH2E, adds: "HH2E stands for the flexible mix of complementary technologies. This makes the use of renewable energies feasible on a large scale. Our goal is to offer hydrogen at fair prices. Innovative technology partners such as Aerzen support us in this. We are pleased to be building a long-term collaboration with Aerzen."
