A groundbreaking project has been proposed in Morecambe Bay, United Kingdom, to excavate up to 20 subsea caverns for storing natural gas, hydrogen, or compressed air. Led by EnergyPathways, the initiative aims to significantly increase the UK's energy storage capacity and reduce the risk of blackouts and supply shortages. The caverns, reaching depths of 200 meters, could store vast amounts of energy, providing crucial backup during periods of low renewable energy production or high demand. This innovative approach utilizes salt cavern storage technology, a proven method for storing natural gas reserves around the world. The project's focus on long-duration energy storage reflects the growing need for stable backup systems to support the UK's renewable energy transition. By leveraging the unique geological features of Morecambe Bay, including the Marram gas field and existing wind farms, EnergyPathways plans to create a self-financing solution that does not burden consumers with added costs. The proposal aligns with national goals for a low-carbon energy system and has the potential to revolutionize how the UK manages its power supply, ensuring a reliable and sustainable energy future.
