UK Oil and Gas PLC (UKOG) has decided to relocate its plans for the UK's largest hydrogen storage caverns project from the Port of Portland to a new site in Dorset. The move is driven by the prospect of higher storage capacity and estimated cost-savings of £450 million. The project at the new location west of Weymouth involves the drilling of 24 salt caverns 1.3km underground, with the potential to store one billion cubic meters of hydrogen. While salt caverns are primarily used for natural gas storage globally, their use for hydrogen storage is limited. Hydrogen can be produced sustainably by splitting water with renewable energy sources like wind and solar power. Despite the prevalent production of 'blue hydrogen' in the UK, extracted from fossil fuels with significant CO2 emissions, UKOG assures that the caverns will be dedicated to storing 'green hydrogen.' In addition, UKOG is contemplating plans for a green hydrogen plant at Portland Port, which could be associated with the new storage site. The relocation decision has been met with positivity by the Port of Portland, which welcomes the opportunity to explore the potential for a green hydrogen pilot plant at the port, signaling a step towards cleaner energy production and storage in the region.
