HotGreen Solutions Raises £1.2 Million to Scale Ultra-Efficient Heat Pump Technology
- ByStartupStory | October 22, 2025
Cleantech startup HotGreen Solutions has secured £1.2 million in a pre-seed funding round led by Empirical Ventures, with strategic participation from Coca-Cola Europacific Partners (CCEP), First Imagine! Ventures, The Conduit Impact Fund, and Almanac Ventures.
The investment comes at a crucial time when industrial process heat — responsible for over 20% of global CO₂ emissions — demands urgent innovation. Faced with rising energy costs and ambitious climate targets, industries are seeking cost-effective, scalable solutions that can dramatically reduce their environmental footprint without major facility disruptions.
Revolutionizing Industrial Heat with Ultra-Efficient Heat Pumps
HotGreen Solutions is developing high-temperature, ultra-efficient heat pumps that produce low-carbon steam tailored for various industrial applications. Their technology integrates seamlessly with existing infrastructure and offers energy efficiencies up to four times greater than traditional boilers.
These systems provide a commercially viable pathway for industries such as breweries, distilleries, and dairy processing plants to reduce energy consumption and operating costs while cutting CO₂ emissions. Typical installations take just 3 to 5 days, minimizing downtime and interruptions to production.
Tangible Impact and Financial Benefits
Industries adopting HotGreen’s heat pumps can expect to save approximately €0.5 million annually on energy costs compared to conventional boiler systems, while avoiding around 3,000 tonnes of CO₂ emissions per year. With such savings, return on investment often occurs in under two years, making it a financially compelling and environmentally responsible choice.
Accelerating Growth and Commercial Deployment
The fresh capital injection will enable HotGreen Solutions to accelerate growth by expanding pilot projects and commercial deployments, particularly within the food and beverage sector — a key market due to its significant heat demand and emission footprint.
This funding round not only provides the means to scale but also validates the startup’s innovative approach to tackling one of the most challenging areas of industrial decarbonization.
Looking Ahead
With global energy demands increasing and climate regulations tightening, HotGreen Solutions’ technology offers a timely, scalable solution that helps industries meet sustainability goals efficiently. The company aims to become a leader in industrial heat decarbonization by enabling businesses to simultaneously achieve cost savings and significant environmental impact.
