HotGreen Solutions is developing ultra-efficient high-temperature heat pumps to electrify industrial process heat.
A UK cleantech startup HotGreen Solutions, has closed a £1.2 million pre-seed round, led by Empirical Ventures, with strategic participation from Coca-Cola Europacific Partners (CCEP), First Imagine! Ventures, The Conduit Impact Fund, and Almanac Ventures.
Industrial process heat accounts for over 20 per cent of global CO₂ emissions yet has seen limited innovation. As energy costs rise, industry needs solutions that cut operating expenses while meeting climate goals.
HotGreen Solutions is addressing this challenge by developing ultra-efficient, high-temperature heat pumps that produce low-carbon steam for industrial applications. The systems integrate with legacy infrastructure, deliver up to four times the efficiency of traditional boilers, and offer a commercially viable way to cut energy use and costs without costly facility overhauls.
Installations take 3–5 days and can help a typical industrial facility, such as a Brewery, Distillery, or Dairy processing plant, save around €0.5 million per year on energy costs versus traditional boilers, while avoiding around 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.
With this new investment, HotGreen Solutions will accelerate its growth and scale up its ultra-efficient heat pump technology through pilot projects and commercial deployments in the food and beverage sector.
