The geomechanics of hydrogen storage in salt caverns: environmental considerations

Summary

The UK is facing the challenge of developing large-scale hydrogen storage to support its Net Zero 2050 target, particularly concerning the geomechanical and environmental impacts of high-frequency storage cycles in salt caverns. This report, published by the Environment Agency, reviews existing knowledge and expert insights on the geomechanics of salt caverns for hydrogen storage, covering planning, operation, and decommissioning. It concludes with the need for further research into the effects of frequent temperature and pressure cycling on cavern integrity, offering strategies for mitigation and monitoring while the technology is still being developed.
