London, United Kingdom, 15th October 2025 – A UK clean-technology startup is developing ultra-efficient high-temperature heat pumps to electrify industrial process heat. The Pre Seed round led by Empirical Ventures includes strategic participation from Coca-Cola Europacific Partners (CCEP), First Imagine!, The Conduit Impact Fund, and Almanac Ventures.
Industrial process heat accounts for more than 20% of global CO2 emissions, yet has been historically overlooked by innovation. With industry facing significantly higher energy bills in recent years, there is an urgent need for solutions that cut operational costs while meeting climate commitments. The company’s ultra-efficient high-temperature heat pump technology provides a commercially viable pathway for industries to reduce both energy consumption and costs. Crucially, these heat pumps integrate seamlessly with existing infrastructure at legacy industrial facilities, delivering four times the efficiency of traditional boilers, enabling immediate impact without requiring costly facility overhauls.
Each installation takes 3-5 days and could help a typical industrial facility, such as a Brewer, Distiller or Dairy processing plant, save €0.5M annually on energy bills compared to traditional boilers, while also avoiding 3,000 tonnes of CO2 emissions* each year. With energy savings of this scale, facilities typically achieve payback in under two years, making this a financially compelling investment that delivers both immediate cost savings and long-term environmental impact.
“This funding milestone is a significant step toward our mission to help industrial plants save cost while cutting carbon. My co-founder and I built HotGreen Solutions out of frustration for the lack of affordable solutions industry had to decarbonise profitably. We saw a clear unmet need for a low-carbon, commercially-viable solution that industry could adopt at scale. Despite rising energy bills and its substantial carbon footprint, industrial heat has seen little innovation. It’s the elephant in the climate-tech room, but also a major market opportunity. Our isothermal compressor technology delivers a leading heat pump solution with clear cost and operational benefits for sectors struggling with energy costs and emissions” said Georgia Ware, CEO and co-founder of HotGreen Solutions.
The investment announced today will accelerate the growth of HotGreen Solutions to scale its ultra-efficient heat pump technology through pilots and deployments within the food and beverage sector.
