UK Oil & Gas (UKOG) has decided to prioritize the advancement of its South Dorset hydrogen storage project over the initial proposal for the Isle of Portland. This shift in focus was driven by the South Dorset project's potential for significantly higher future annual revenue and a more competitive stance for government revenue support. UK Energy Storage, a subsidiary of UKOG, is spearheading the South Dorset project involving 24 salt caverns 1.3km below ground. The project boasts a capacity up to 2.9 times greater than the Isle of Portland proposal, with a maximum storage capacity of 30.2 TWh per year. Additionally, the use of a cushion gas scheme in South Dorset is expected to slash project development costs by 36% in comparison to the original site. With estimated costs of £800 million, the South Dorset endeavor is notably more cost-effective than the Portland project. UKOG intends to seek government support for only one of its projects, deeming South Dorset as the more economically competitive choice and therefore abandoning the Portland project. By focusing on South Dorset and its East Yorkshire counterpart, UKOG anticipates project construction to commence before 2030, with initial operations projected between 2030 and 2032. The company received support from RWE for its hydrogen storage plans and acquired its East Yorkshire site with investor funding. The UK is witnessing increased investment in hydrogen storage, with various oil and gas companies like Centrica and Kistos exploring projects for energy transition and decarbonization.
