Eos Energy and Frontier Power have signed a memorandum of understanding to advance long-duration energy storage in the UK, marking Eos’ entry into the British market with a 5GWh framework agreement.
The deal supports Frontier’s plans to bid into Ofgem’s new long-duration energy storage (LDES) cap and floor scheme using Eos’ Znyth™ zinc-based battery technology, they said.
Justin Vagnozzi, senior vice president of global sales at Eos, said: “We are proud to partner with Frontier Power, a respected leader in UK energy development, to bring Eos’ safe and recyclable storage technology to a new market.
“The novel cap and floor scheme incentivises investments in long-duration storage technologies that are critical for grid stability and renewable integration.
“Our participation in this scheme with an established global supply partner like Frontier furthers our commitment to scale our operations, expand our market reach and encourage the adoption of alternative technologies for the energy storage market.”
The companies also intend to explore opportunities to collaborate in new international markets and consider establishing local manufacturing in the UK.
Joe Mastrangelo, CEO of Eos, said: “We can co-locate manufacturing capacity near customer demand and not only provide innovative energy storage, but sustainable jobs in regions that have demand for our technology.
“As that demand grows, both domestically and internationally, we’ll expand our manufacturing footprint, and we’re excited to partner with Frontier to execute on that vision in the UK market and beyond.”
Humza Malik, CEO of Frontier Power, added: “This agreement reflects Frontier Power’s commitment to driving innovation in clean energy while fostering international collaboration.
“By working with Eos, we are advancing our portfolio of long-duration storage projects and strengthening trade relations between the US and UK.
“The prospect of local manufacturing in the UK could further boost economic growth and job creation.”
The UK’s LDES scheme, administered by Ofgem and the Department for Energy Security and Net Zero, aims to incentivise investment in innovative energy storage technologies by offering long-term revenue certainty.
Eos said its eight-hour Znyth™ battery technology is well suited to the scheme’s objectives and supports the UK’s broader goals for grid stability and renewable integration.
The agreement will be incremental to Eos’ reported pipeline as of 31 March 2025.
