About Caldera
Caldera is on a mission to make sustainable, zero-carbon heat accessible and affordable for industry. Leveraging patented technology that has captured attention from 12 sectors across 15 countries, we’re tackling one of the climate crisis’s most overlooked challenges: industrial heat.
Based in Hampshire, just outside London, our headquarters serve as a comprehensive centre for innovation. Here, we manage everything from initial product development and prototyping to full-scale production. Our team, united by a passion for climate solutions, brings together a diverse range of expertise and backgrounds. Together, we’re not just imagining a cleaner future; we’re building it.

We invent our vacuum insulation and heat extraction systems and combine our newly developed technologies in a 100kWh prototype.
We fit the first 100kWh unit in our CEO’s home. It’s still there today and shows that our technology is a safe and reliable solution to provide heat using 100% sustainable energy.

Our crowdfunding campaign is a big success – 1,300 people invest on CrowdCube, raising £1.5m and exceeding our goal by 250%.
We’re awarded a total of £0.8m in UK government funding to help us achieve the full potential of our technology. We put ten 100kWh units on long-term test in homes and a church and begin development of a larger-scale unit for industrial heat decarbonization.

We win £4.3m of UK government funding for a follow-on project to develop a full-scale test facility at our factory and demonstrate a 4MWh industrial storage boiler.
We celebrate another highly successful crowdfunding campaign, raising £1.5m. Our industrial storage boiler demonstrator is commissioned and achieves its target to charge at 1MWe, and discharge steam at 1,000kg/h.
