The Hydrogen Pilot Cavern (HPC) Krummhörn demonstration plant, part of Uniper's strategic plan, has been inaugurated in Lower Saxony, Germany. This project includes the storage of a gas mixture of natural gas and hydrogen in a pore storage facility. The pilot cavern in Krummhörn, with a volume of approximately 3,000 cubic meters, has been completed using solution mining techniques. The storage facility is set to store nearly 500,000 norm cubic meters of green hydrogen, representing one of the pioneering projects of its kind. The trial operation commenced with a gas tightness test, leading to future injection and withdrawal cycles to gain insights into equipment compatibility, gas quality, and process technologies. Uniper is investing a significant amount in this green project, with funding from the Lower Saxony Ministry for the Environment, Energy and Climate Protection. The project aims to enhance the region's energy landscape and strengthen Lower Saxony's position as an energy hub in Central Europe. Uniper's transition towards carbon neutrality by 2040 involves significant changes in its power generation, with a focus on increasing the share of zero-carbon capacity by 2030. The company is expanding its portfolio to include green gases like hydrogen and biomethane, emphasizing the importance of renewable energy sources for a sustainable future.
