Norway’s Enerin has raised €15 million in Series A funding, with participation from Climentum Capital, The Footprint Firm, Johnson Controls and Move Energy, with participation from PSV Hafnium and Momentum. The company develops modular high-temperature heat pumps capable of supplying industrial process heat up to 250°C, targeting sectors that rely on fossil-fuel boilers. Enerin plans to use the funding to expand manufacturing capacity, formalise serial production, and advance the next generation of its HoegTemp system.
Founded in 2017 and headquartered in Asker, Enerin aims to provide a standardised pathway for factories to reduce reliance on fossil-fuel heat without overhauling existing operations. The company’s next phase will test whether its technology can scale beyond pilot sites and meet cost and reliability expectations in global industrial settings.
“This investment marks our shift from pioneering to full industrialisation, bringing proven hightemperature technology from Norway to industries worldwide,” said Arne Høeg, Founder and CEO of Enerin AS. “Industrial companies are ready to decarbonise high-temperature heat, but the mass market has lacked simple, profitable solutions that fit everyday operations.”
Enerin’s technology targets one of industry’s most difficult decarbonisation gaps: heat demand above 100°C, where fossil-fuel boilers remain dominant. The company’s HoegTemp system—based on Stirling-cycle thermodynamics—is engineered to supply process heat up to 250°C using electricity and recycled heat. This temperature range accounts for a significant share of industrial CO₂ emissions, yet conventional heat pumps typically cannot operate efficiently or reliably under such conditions.
“Today, customers care first about economics. HoegTemp makes clean industrial heating profitable compared to gas boilers, reducing energy use by 50-70 percent,” said Høeg. “Because our automated system adapts to varying process conditions, it allows factories to decarbonize without redesigning operations. This blend of flexibility and standardisation is what finally makes clean industrial heat available and profitable at scale.”
The Series A financing will enable Enerin to expand its manufacturing capacity, standardise its modular heat-pump units, and accelerate development of next-generation designs. The move from bespoke builds to repeatable production is central to the company’s plan to serve larger industrial markets.
“Securing an oversubscribed international Series A in the current market demonstrates strong confidence in both our technology and the team’s ability to leverage our repeatable, standardized configuration to scale globally,” said Henrik Ree Eriksen, CFO of Enerin.
Enerin’s technology has already been tested with early adopters in pharmaceuticals, animal feed and biogas, including GE Healthcare, Pelagia, and IVAR IKS Biogas. It has also been named a finalist for New York State’s Empire Technology Prize, which focuses on clean-heating innovation.
Investor interest reflects the broader search for scalable solutions in mid-temperature industrial heating—an area still dominated by fossil fuels despite being central to decarbonisation strategies.
“Decarbonization and energy efficiency are strategic pillars of Johnson Controls, critical for the environment while delivering business growth for our customers. Across our projects we have consistently helped customers cut energy costs and emissions by up to 50–60 percent compared to conventional gas boilers. Our investment in Enerin extends that impact to higher temperature ranges where electrification is most challenging,” said Gilad Domb, Vice President of Product Management, Strategy, and Ventures at Johnson Controls.
Other investors emphasise the absence of mass-market technologies capable of operating at this temperature range with compactness and flexibility.
“After years of tracking industrial heat-pump technologies, we consistently found solutions that were either too large, too niche, or too bespoke for true mass-market adoption. Enerin changes that. Their Stirling-cycle design combines efficiency with the compactness and operational flexibility needed to replace gas boilers across the vast mid-size segment,” said Stefan Mård, Partner at Climentum.
From a European climate-investment perspective, the opportunity lies in addressing a segment of heat demand where electrification could significantly reduce emissions if technical barriers are removed.
“Industrial heat in the 100–200°C range represents a massive yet untapped decarbonization opportunity, still dominated by fossil fuels. Enerin is breaking new ground by turning industrial waste heat into clean, reliable thermal energy. This is exactly the kind of innovation that can move the needle on industrial emissions at scale, and we’re thrilled to co-lead this round,” said Sofie Käll, Chief Investment Officer at The Footprint Firm.
For the board, the round represents validation from both corporate and venture investors that the technology may be able to scale across varied industrial contexts.
“Having Johnson Controls together with leading European VCs as investors is a powerful validation of what Enerin is building,” said Raymond Carlsen, Chair of Enerin and former CEO of Scatec ASA. “I’ve spent an essential part of my career enabling renewable energy generation on the supply side. Now it’s time to decarbonise the demand side without a green cost premium.”
