Norway-based Enerin has closed an oversubscribed €15 million Series A funding round led by Climentum Capital, The Footprint Firm, Johnson Controls, and Move Energy. The round, which also saw participation from PSV Hafnium and Momentum, positions the company to move from custom projects to standardized production of its HoegTemp high-temperature heat pump technology.
The funding comes as industries worldwide search for economically viable alternatives to fossil-fueled boilers, which account for nearly 20% of global CO₂ emissions. Unlike conventional heat pumps that struggle with industrial process demands, Enerin's modular system automatically adjusts to factory conditions while delivering temperatures up to 250°C.
Industrial decarbonization has long been stalled by a fundamental problem: traditional heat pumps can't handle the variable conditions and high temperatures that factories require. Enerin designed its solution around this constraint rather than against it.
"Industrial companies are ready to decarbonise high-temperature heat, but the mass market has lacked simple, profitable solutions that fit everyday operations," said Arne Høeg, Founder and CEO of Enerin.
The company's HoegTemp system uses Stirling cycle technology to deliver steam or hot water with what the company describes as exceptional efficiency and control. More importantly for industrial operators, it reduces energy consumption by 50-70% compared to gas boilers while adapting to changing process requirements without operational redesign.
Enerin has focused on making the business case work first, recognizing that environmental benefits alone won't drive industrial adoption at scale.
"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 flexibility, and standardisation is what finally makes clean industrial heat available and profitable at scale."
The approach has attracted blue-chip pilot customers including GE Healthcare, Pelagia, and IVAR IKS Biogas in the pharmaceutical and animal-feed sectors. Separately, New York State named HoegTemp as a finalist for the $10 million Empire Technology Prize for clean heating applications.
The Series A capital will fund Enerin's transition from project-based manufacturing to standardized module production. This shift represents a critical inflection point for a company that has spent years proving its technology works in demanding industrial environments.
"This investment marks our shift from pioneering to full industrialisation, bringing proven high-temperature technology from Norway to industries worldwide," said Høeg.
Henrik Ree Eriksen, CFO of Enerin, emphasized the significance of closing an oversubscribed round in today's funding environment. "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," he said.
Johnson Controls' participation as both investor and lead adds strategic weight beyond capital. As one of the world's largest energy systems providers, the company brings manufacturing expertise, distribution networks, and customer relationships that could accelerate Enerin's international expansion.
"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.
The investor syndicate combines climate-focused venture capital with industrial expertise. Climentum Capital and The Footprint Firm bring experience scaling climate tech companies, while Move Energy adds sector-specific knowledge of energy transition technologies.
Founded in 2017 and based in Asker, Norway, Enerin has spent seven years developing and refining its high-temperature heat pump technology. The company chose to base its system on the Stirling cycle, an engine design that offers better performance characteristics for industrial applications than traditional heat pump architectures.
The modular, standardized approach allows factories to install units that match their specific heating requirements without extensive customization. As production scales, this design philosophy should enable faster deployment and lower costs compared to bespoke industrial heating solutions.
With proven technology, early customer traction, and capital to industrialize production, Enerin is positioning itself to address one of the more stubborn challenges in industrial decarbonization.
