First of a kind hydrogen storage facility set for HyNet


Costain is set to oversee the development and front end engineering design (FEED) study for a first of a kind hydrogen storage facility for the HyNet project.

On 8 October, Costain detailed how the facility would be developed in the southern part of Holford Brinefield in Cheshire, storing up to 1.3TWh of hydrogen underground in salt cavities. Excess hydrogen will be stored here in periods of low demand, before then being discharged into the network during peak winter periods. This will ensure that supply and demand can be balanced within the HyNet hydrogen system.

Costain will be tasked with undertaking an initial concept study that can demonstrate the requirements of the import, storage and export of hydrogen at the facility. This will form the basis of a targeted FEED study package for the hydrogen facility.

HyNet itself, once completed, will directly remove over 1mn tonnes of CO2 from regional industry, potentially saving more than 25mn tonnes of carbon each year. It will create the UK’s first full chain, integrated low carbon hydrogen supply system of production, distribution network, bulk storage and consumption.
