Assessment of underground energy storage potential to support the energy transition in the Netherlands

The Ministry of Economic Affairs and Climate commissioned in 2018 a technical assessment on the various options for underground storage in the Netherlands. The technologies investigated were those that can support the large-scale increase of renewables, secure energy supply, and can be implemented in the subsurface (depths >500 m) and deployed within the next 10-30 years. This paper presents part of the results showing the large potential storage capacity for natural gas (1939 Twht) and hydrogen (456 Twht) in depleted gas fields, and natural gas (184 TWht), hydrogen (43 TWht) and compressed air (0.58 TWh) in salt caverns.
