UKRI’s new £28 million Ultra-LDES Challenge backs 100-hour discharge systems—advanced batteries and underground hydrogen storage—to bridge multi-day renewable gaps.
To help fortify the UK’s electricity grid during those frustrating stretches when wind and solar power take a back seat, UK Research and Innovation (UKRI) is rolling out the Ultra-Long Duration Energy Storage (Ultra-LDES) Challenge. They’ve got a hefty £28 million in public funding backing this initiative, which aims to bolster systems capable of storing and delivering clean power for at least 100 hours—enough to cover those pesky gaps that can last up to four days or longer when renewable energy generation dips.
Why Multi-Day Storage Matters
As we see more and more wind and solar energy contributing to the…
