LONDON (ICIS)–A report from the UK’s Royal Society published 8 September said that Great Britain needs as much as 100TWh of storage capacity by 2050 to manage periods of low renewable generation, with hydrogen storage in salt caverns the preferred option for storage.
The report states that GB could have as much as 200GW of renewable capacity available in the form of wind and solar, but this generation mix must be backed up by large-scale storage if renewable output is below demand expectations.
The report said that “meeting the need for long-duration storage will require very low cost per unit energy stored. In GB, the leading candidate is storage of hydrogen in solution-mined salt caverns.”
In its medium scenario (GB power demand of 570TWh/year by 2050) between 60TWh and 100TWh of hydrogen storage in salt caverns would be required, much less that the theoretical maximum capacity of around 3,000TWh, according to the British Geological Survey.
