German hydrogen playe HH2E AG & the Swiss MET Group have announced a partnership to develop one of the largest green hydrogen production plants in Europe to date in Lubmin Mecklenburg-Vorpommern on the German Baltic coast. The project aims to construct a new generation power-to-X plant with a capacity to produce around 6,000 tonnes, over 200,000 MW, of green hydrogen per year. A second-stage expansion is planned to increase capacity to over 1 GW, which will produce more than 60,000 tonnes of green hydrogen per year and help avoid more than 800,000 tonnes of direct CO2 emissions annually.The technology mix developed by HH2E for the green power plant in Lubmin is another step towards 100% renewable energy, for all sectors and around the clock. The volatility of renewable energy production is solved by combining a 50 MW alkaline electrolyser with a 200 MW high-capacity battery, which enables constant production of green hydrogen without a permanent supply of renewable power. The renewable power input is to be secured through long-term power purchase agreements from offshore and onshore wind farms as well as solar parks in the region.The partnership between HH2E and MET Group is taking shape with the foundation of the project company H2 Lubmin GmbH, which will be responsible for the development of the project, the construction and long-term operation of the new plant.Construction of the first phase of the plant in Lubmin with total investments of over 200 million euros is to begin as early as 2023. Commissioning is planned for 2025. Commissioning of the second stage is scheduled for 2030. The total investment can exceed 1 billion euros.
