A British energy company is in the process of planning a groundbreaking project to dig a massive salt cavern under Portland Port in the UK. This cavern, if constructed, would serve as a storage facility for hydrogen and is expected to receive fast-track approval and government support. The size of this storage facility would be unprecedented in the UK, with a capacity twice that of all existing salt cavern complexes combined. Additionally, plans for a second phase of development aim to double the storage capacity. Salt caverns are considered ideal for hydrogen storage due to their airtight properties, ease of excavation, and solid enclosure provided by the salt formations. The process involves creating caverns by drilling wells, injecting water, and dissolving out salt to the desired size. The strategic location of the facility at Portland Port positions it near key industrial sites, the Hinkley Point nuclear plant, and new offshore wind power sources, making it well-suited to support the UK's hydrogen storage needs and renewable energy goals. The facility is envisioned to provide a substantial portion of the UK's hydrogen storage requirements by 2035 and function as a hydrogen battery for balancing renewable power supply fluctuations. The Bacton Energy Hub, a core supplier, plans to produce hydrogen using carbon capture technology from natural gas and distribute it to the salt caverns for storage and distribution. The historical and operational significance of Portland Port, with its naval history and current role in agriculture, cruise lines, and offshore operations, adds to the project's uniqueness and potential impact on the energy landscape.
