Royal Society - Large Scale Hydrogen Storage / Ballylumford Power to X3 Sep 2024 11:28
In Sep 2023, the Royal Society published a GB focussed large-scale electricity storage policy briefing.

This policy brief considers the role large-scaleelectricity storage will need to play in a GBelectricity system supplied largely by wind andsolar. The analysis of the amount and type of storage that will be needed allows for baseload nuclear
power or gas with CCS. Ultimately, the optimum mix will depend on costs, security and sovereignty of supply and the level of carbonand methane emissions considered acceptable. Resilient planning assumptions will need to be made to reach net zero by 2050 cost effectively. The need for storage and how it can best be provided depend on local factors, including the demand profile, the weather and climate, and the potential storage technologies and available
sites. While this brief focusses on GB, the methodology and the conclusions on storage technologies are applicable elsewhere.
The Royal Society policy briefing says :
"What electricity storage will be needed, and what are the alternatives?
Electricity can be stored in a variety of ways, including in batteries, by compressing air, by making hydrogen using electrolysers, or as heat. Storing hydrogen in solution-mined salt caverns will be the best way to meet the long-term storage need as it has the lowest cost per unit of energy storage capacity."
In addition to the Atkins report, The Ballylumford Power to X project (approx 1m pounds, UK Govt, BEIS funded) highlights the role Islandmagee can play .
"The Ballylumford Power-to-X Project Phase One report proves that a fully green gas network for Northern Ireland is not just a pipe dream.
The first of its kind in NI, the research shows that a full cycle hydrogen economy can be achieved, fostering growth in the renewables sector, creating thousands of jobs, bringing inward investment, whilst helping the UK meet its net zero targets."
