A recent report by Centrica and FTI Consulting has shed light on the potential benefits of hydrogen storage in the UK. It is estimated that by 2050, the country could save up to £1 billion annually through this approach. By repurposing existing facilities, such as the Rough gas storage site, to store hydrogen, the energy grid's stability can be enhanced while effectively managing the intermittency of renewable energy sources. Centrica has already pledged £2 billion towards this initiative, but further support from the government and regulators is crucial to make it a reality. Chris O’Shea, the Group Chief Executive of Centrica, envisions hydrogen as a significant energy reserve in a net zero system, offering electricity during periods of low wind and solar generation. The aim is to transform the Rough storage facility into the world's largest hydrogen storage site, marking a crucial step towards building the energy system of the future.
