Latest Corre Energy announcements, branding and media information.


Corre Energy B.V is focused on the development, construction, & operation of grid-scale underground long-duration energy storage, combined with the production and sale of green hydrogen. Corre Energy is headquartered in the Netherlands.

Compressed Air Energy Storage (CAES) is a proven energy storage technology that involves using electricity to compress air in underground storage caverns, which can later be released and combined with hydrogen to generate electricity. Corre Energy has developed a system where renewable electricity is used to compress air and generate green hydrogen, both of which are stored in separate co-located underground caverns. When electricity demand is high/supply is low, air and green hydrogen are combined by an electrolyser to generate electricity in a decarbonised system.

Corre Energy has two projects at a progressed stage of development – the first is a joint project in the Netherlands (ZW1) where Corre Energy has partnered with Infracapital (part of M&G Group). The second project is in Denmark, with Corre Energy currently owning 100%. Both projects are expected to come on-stream in 2025/ 2026 and reach full profitability by 2030. These projects cost €300-500m each (depending on project type) to construct and are expected to generate EBITDA of circa €80m each at maturity.

In addition to the two projects under construction, the Company also has a pipeline of additional EU designated projects across the Netherlands, Germany and Denmark.

The Technology

Underground energy storage in the form of compressed air provides a low-cost storage solution for a minimum of 10-12 hours, and subject to cavern sizes, a duration of 80-100 hours can be achieved for 300 MW+ of energy storage. A combination of relatively unlimited storage cycles and significantly lower capital costs provides for much lower annualised costs for CAES versus lithium-ion battery.

Compressing air or hydrogen in salt caverns is an economically viable, scalable storage technology that will be able to reach true grid scale (100s of megawatt (“MW”) per installation) and offer both short and long-term duration storage.

CAES has been operating reliably and safely since 1978 in Germany and 1991 in the U.S. The technology uses specifically designed underground storage caverns created in geological salt deposits by a process known as solution mining or leaching.

During operation of the CAES facility, in the storage phase, electricity is used to compress air into the storage cavern. In the generation phase, the compressed air is released and pre-heated using a fuel to drive turbines, producing electricity when required.

One CAES cavern of 1 million cubic metres can generate 320MW of power within a 12-24 hour duration.
