US-based Eos Energy Enterprises and UK developer Frontier Power have signed a memorandum of understanding (MoU) for a 5GWh framework agreement for Eos’ Zynth battery technology.
The agreement covers Frontier Power’s projects, which it plans to submit into the first application window of Ofgem’s new long-duration energy storage (LDES) cap and floor scheme.
It is Eos’ first foray outside of the US, but the zinc hybrid cathode battery firm said the collaboration could extend to international markets too. The agreement will add to Eos’ pipeline numbers starting from March 31, 2025.
Frontier Power also recently announced a deal with another non-lithium battery company, vanadium redox flow battery (VRFB) firm Invinity Energy Systems, to submit bids for projects in the LDES scheme with Invinity’s tech too.
The developer has now signed a joint development agreement with Ethos Green Energy for exclusive access to multiple grid connection points which could support up to 20GWh of LDES projects using multiple technology solutions, Invinity recently said.
Frontier has reserved up to 2GWh of Invinity’s manufacturing, but the Eos announcement is further evidence of it considering multiple different technologies.
Last month, Eos said it expects 2025 revenues to be around ten times higher than last year’s, when it saw US$15.6 million.
