Uniper is embarking on a pioneering project in Krummhörn, Lower Saxony, to demonstrate the full potential of green hydrogen storage in salt caverns. The Hydrogen Pilot Cavern (HPC) project involves setting up a pilot cavern with a volume of around 3,000 cubic meters, aiming to store almost 500,000 cubic meters of green hydrogen. The project launch attracted significant attention, with Lower Saxony's Minister for Economic Affairs and Uniper's CEO attending the event, alongside 300 local visitors. Uniper's plans include expanding the Krummhörn site to offer a storage capacity of 250 GWh of hydrogen and developing a total capacity of up to 600 GWh by 2030 across various locations in Lower Saxony and North Rhine-Westphalia. The project will involve rigorous testing of equipment, materials, real-life storage conditions, and hydrogen quality. With a gas-tightness test scheduled and operational cycles planned, this initiative signifies a significant step towards advancing hydrogen storage technology in Germany.
