He national gas project in Dorset refers to a large-scale hydrogen storage project, with the main components being the development of salt caverns and the connection to National Gas's "Project Union" hydrogen pipeline network. UK Oil & Gas (UKOG) is leading the development, with a new plan to site underground caverns west of Weymouth. This project aims to store hydrogen in underground salt caverns and connect it to a national hydrogen backbone, contributing to the UK's energy transition.
Project details
Project lead: UK Oil & Gas (UKOG) is the primary developer of the storage project.
Project partner: National Gas is the company responsible for the national pipeline infrastructure (Project Union) and is partnering with UKOG.
Technology: The project will use underground salt caverns to store hydrogen, a renewable energy alternative to natural gas.
New location: Plans have been moved from the Port of Portland to a new site west of Weymouth in Dorset.
Cavern details: The new plans involve creating 24 salt caverns 1.3 km underground, potentially storing one billion cubic meters of hydrogen.
Project goals and connections
Energy storage: The caverns will store hydrogen, providing a large-scale method for energy storage to support a cleaner energy system.
National network integration: The storage facility will be connected to National Gas's "Project Union," a proposed national network for transporting 100% hydrogen through repurposed parts of the existing gas transmission system.
Energy security: This project is part of a larger effort to create a hydrogen economy across the UK and enhance energy resilience.
