German power firm Uniper has entered into a conditional supply contract with organic solid flow battery company CMBlu Energy for the delivery of at least 5GWh of its technology.<\/p>\n\n\n\n

The long-term framework agreement runs until 2037 and gives Uniper the option to take delivery of battery systems from CMBlu in tranches of at least 100MWh each, starting in 2027.<\/p>\n\n\n\n

It follows a site acceptance test (SAT) of CMBlu\u2019s battery system by Uniper. Both companies are headquartered in Germany.<\/p>\n\n\n\n

CMBlu\u2019s SolidFlow battery is based on the unique and patented combination of organic redox flow technology with solid-state storage materials and is specifically designed for market-driven use in the multi-hour range, the company said.<\/p>\n\n\n\n

It claims high cycle stability, a lifespan of several decades and non-flammable electrolytes. It also benefits from the absence of critical raw materials such as lithium, cobalt, or nickel, as with most other non-lithium-based battery technologies.<\/p>\n\n\n\n

Uniper first announced plans to pilot CMBlu\u2019s tech at a project in Germany back in 2023. It has also tested other flow battery technologies, including that of Dutch firm Elestor, announced the previous year<\/a> in 2022. It has also looked at the economic feasibility of large-scale green hydrogen storage, winning a small grant from the EU for a project the same year<\/a>.<\/p>\n\n\n\n

Uniper is a spinout of the larger German-headquartered utility and power firm E.ON.<\/p>\n\n\n\n

While the firms didn\u2019t which countries they were targeting for deployments, both are headquartered in Germany so the first projects may well be there.<\/p>\n\n\n\n

If so that could represent a shift in appetite for the technology. In 2022, a flow battery executive speaking anonymously lamented that the country\u2019s energy sector \u2018did not think it needed flow batteries\u2019<\/a>, instead believing that a combination of lithium-ion for short-duration and green hydrogen for long-duration would suffice.<\/p>\n\n\n\n

However, since then the green hydrogen sector has struggled to scale. Perhaps in related developments, flow batteries appear to have become more viable for large-scale projects. In that time, a flow battery firm VoltStorage raised a \u20ac30 million venture loan<\/a>, a 10MWh project has been completed<\/a>, and power firm LEAG seriously considered building a 500MWh project using iron flow batteries from ESS Inc<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
