The Solution

Underground energy storage in the form of compressed air and green hydrogen can provide one of the cheapest forms of energy storage using proven technology. This reflects long asset life (35 years plus), unlimited storage cycles, and significantly low capital costs.

The Green Hydrogen Hub Denmark project, of which Corre Energy is the consortium lead, utilises green hydrogen and CAES to provide sustainable energy for a range of purposes.

The EU market

The EU recognises the importance of energy storage in helping to achieve security of supply and decarbonisation objectives. Grid-scale, hydrogen-fuelled compressed air and hydrogen storage in salt caverns is pivotal in supporting the transition to the wider hydrogen economy on a continental scale.

The EU Green Deal calls for the acceleration of renewables, green hydrogen and storage, stating these are needed for deep decarbonisation and the achievement of the 2050 targets.

Corre Energy's project roadmap with solutions of hydrogen-fuelled compressed air and hydrogen storage in salt caverns are globally scalable technologies that can offer decarbonisation and accelerate the journey towards net-zero targets.

Energy transition

The EU’s objective is to reach over 80% renewable energy by 2050. Corre Energy is accelerating this energy transition through underground energy storage by developing, building and operating storage systems in salt caverns, specifically hydrogen-fuelled Compressed Air Energy Storage (CAES), green hydrogen production, and storage in salt caverns.

Corre Energy’s roadmap includes several potential projects in the pipeline, initially with two in the Netherlands and two in Denmark, Corre Energy has further underground energy storage projects located across the globe. These projects have been recognised by the European Network of Transmission System Operators for Gas (ENTSOG), and included on ENTSOG’s Ten Year Network Development Plan (TYNDP).
