UK-based Exergy3<\/a>, a thermal energy storage startup, has raised \u00a310 million (~$13.5 million) in a seed funding round, led by Axeleo Capital through its Article 9 Green Tech Industry I fund, with participation from Bayern Kapital and Kibo Invest.<\/p>\n\n\n\n

Existing investors Scottish Enterprise, Zero Carbon Capital, and Old College Capital, the University of Edinburgh\u2019s in-house venture investment fund, also participated in the round.<\/p>\n\n\n\n

The company will use the funding to accelerate commercialization, including scaling its modular thermal energy storage systems and expanding its presence across industrial markets in Europe.<\/p>\n\n\n\n

According to Exergy3, industrial heat accounts for a significant share of global energy demand and emissions but remains difficult to decarbonize because it relies on high, continuous temperatures across a wide range of processes.<\/p>\n\n\n\n

The company aims to address this gap by linking excess renewable generation to industrial energy demand through modular thermal energy storage units that convert renewable electricity into high-temperature heat.<\/p>\n\n\n\n

Exergy3 states that its technology is designed to deliver process heat ranging from 50\u00b0C to 1,200\u00b0C, allowing it to adapt to a wide range of industrial processes, from direct heat applications to steam generation, making it applicable across energy-intensive industries.<\/p>\n\n\n\n

Markus Rond\u00e9, CEO at Exergy3, said: \u201cThese are two sides of the same problem. Industry needs reliable, high-temperature heat, while large amounts of renewable electricity are going to waste. Exergy3 brings them together, turning surplus renewable power into reliable, low-cost heat for industry. That means lower emissions, lower energy costs, and a more resilient energy system. This funding allows us to move rapidly from pilot to commercial deployment.<\/p>\n\n\n\n

According to Mercom\u2019s Annual and Q4 2025 Funding and M&A Report for Energy Storage report<\/a>, VC funding in the Energy Storage sector in 2025 increased 30% YoY, to $4.8 billion across 75 deals, up from $3.7 billion across 84 deals in 2024.<\/p>\n\n\n\n

In March 2026,  MGA Thermal, a provider of thermal energy-based long-duration energy storage systems, secured<\/a> A$17 million (~$12 million) in funding. The latest round brings the total capital raised to more than A$50 million (~$35 million).<\/p>\n","protected":false},"excerpt":{"rendered":"
