The UK's largest hydrogen storage cavern project has shifted its location to Dorset, west of Weymouth, citing higher storage capacity and cost savings of £450m. UK Oil and Gas PLC plans to drill 24 salt caverns 1.3km underground, capable of storing one billion cubic meters of green hydrogen. While most UK hydrogen is currently 'blue hydrogen' derived from fossil fuels, UKOG reassures that the new caverns will store green hydrogen generated from renewable sources. The project is part of a broader shift towards sustainable energy solutions, with considerations for a green hydrogen plant at Portland Port. Salt caverns, traditionally used for storing natural gas, offer a promising solution for hydrogen storage and extraction. This development marks a significant step in advancing the green hydrogen sector in the UK.
