Eneco, Corre Energy partner on Compressed Air Energy Storage

Storage

The Netherlands – Eneco and Corre Energy have agreed to work together to build a Compressed Air Energy Storage (CAES) facility in the municipality of Zuidwending, in the province of Groningen.

A CAES is a place where compressed air is kept for use in creating power by storing it in salt caverns. The facility’s 220 MW compression capacity and 320 MW production capacity will both be utilized in full by Eneco. There will be a further decrease in CO2 emissions as a result of this next step towards the sustainable energy system of the future.

The CAES is used by Eneco to help balance the electrical grid because of its high level of flexibility. Compressed air can be used to store excess renewable electricity generation. The facility will use the compressed air to generate electricity when there is a shortfall on the electrical grid. In this manner, the CAES can deliver renewable wind and solar energy when neither the wind nor the sun are shining.

Long Duration Energy Storage

Long Duration Energy Storage (LDES) is another name for Compressed Air Energy Storage (CAES). This system employs up to 220 MW to compress excess sustainable electricity into compressed air, which is subsequently stored in salt caverns below ground. When there isn’t enough wind or sunlight, compressed air can be directed toward a turbine to generate additional electricity. This project can save CO2 emissions by 250,000 tons annually by supplying the grid with power with a capacity of 320 MW for up to 3.5 days at a time. The decrease in CO2 emissions will rise to 450,000 tons annually once hydrogen can be used to power the system.
