Hydrogen Storage in Caverns 2023

Home » Events » Hydrogen Storage in Caverns 2023

HyDEX will be running a number of events this year for partners, businesses and organisations with an interest in our programme.

Loading Events

Energy storage is going to be absolutely central to the timely achievement of Net Zero. That storage will have to be applied over a vast spectrum of times ranging from fractions of a second to many months – and possibly more than a year.

Storing pure hydrogen in caverns has a vital role to play in this, because the transformations from primary energy to hydrogen and back to usable energy are so relatively straightforward.

This event, which takes place at the Geological Society in London on Wednesday 29th March, sets out to explore some of the key challenges involved in deploying the necessary amounts of hydrogen storage in caverns.

Event Summary

The event will examine:

  • The potential in the UK for making salt caverns to store hydrogen
  • The technical challenges of storing hydrogen in caverns
  • How hydrogen storage blends with large-scale compressed air energy storage and other thermo-mechanical energy storage solutions much better suited to shorter timescales than hydrogen.
  • Examination of case studies of hydrogen storage in caverns

It will conclude with a panel session comprising experts from academia and industry.
