Enerin Raises €15 Million Series A to Scale Modular High-Temperature Heat Pumps for Industrial Decarbonisation
Enerin, the Norway-based clean-technology company developing modular high-temperature heat pumps for industrial decarbonisation, has successfully closed an oversubscribed €15 million Series A funding round, marking a major step in its transition from technology pioneer to industrial-scale manufacturer. The investment underscores growing investor interest in scalable solutions that replace fossil-fuelled boilers with electrified and efficient heating systems in heavy industry.
Founded in 2017 and headquartered in Asker, Enerin has focused on creating its HoegTemp system — a modular high-temperature heat pump based on Stirling-cycle technology capable of delivering temperatures up to 250 °C. This range targets one of the most challenging decarbonisation gaps in industrial energy use, where traditional heat pumps have struggled to meet process demands and where fossil boilers remain dominant despite accounting for a large share of global CO₂ emissions.
The €15 million Series A round was led by a syndicate of strategic and climate-tech investors including Climentum Capital, The Footprint Firm, Johnson Controls and Move Energy. Additional participation came from PSV Hafnium and Momentum, rounding out a group that combines venture expertise with industrial and energy-sector insight.
Enerin’s leadership said the oversubscribed raise reflects strong confidence in both its technology and its team’s ability to scale production and serve the global industrial heat market. With this funding, the company plans to expand manufacturing capacity, transition to serial production of standardized HoegTemp modules, and accelerate development of next-generation heat pump systems designed to make electrified industrial heat both technically feasible and economically compelling.
In contrast to bespoke system builds, Enerin’s modular approach aims to offer factories a repeatable, scalable solution that can integrate with existing operations without the need for extensive process redesign. This standardisation is seen as a key differentiator in enabling broad adoption across sectors that rely heavily on high-temperature heat, such as chemical processing, food and beverage production, and other heavy industries.
One notable strategic dimension of the round is the participation of Johnson Controls, a global leader in energy systems and building solutions. Johnson Controls’ involvement not only provides capital but also opens pathways for commercial validation and global reach, tapping into its extensive worldwide network and experience in delivering sustainable technology solutions. Enerin’s leadership described this partnership as a powerful validation of the company’s business model and technical direction.
Enerin’s heat pump technology has already been tested in pilot deployments with several early adopters, including blue-chip industrial customers from sectors such as pharmaceuticals and feed processing. These pilots have demonstrated the ability of HoegTemp units to adapt to variable process conditions, delivering high-temperature heat with significant energy savings — reportedly reducing energy use by roughly 50–70 percent compared with conventional gas boilers.
The funding arrives at a moment when electrification of industrial heat is receiving increased attention as a crucial component of global decarbonisation strategies. Industrial boilers, particularly those burning fossil fuels, represent a persistent challenge due to the high temperatures and variable conditions involved. Enerin’s technology responds directly to this challenge by combining advanced thermodynamics with flexible operation that can fit into typical factory environments.
Enerin has framed its mission around enabling profitable decarbonisation — solving not only the technical but also the economic obstacles that have hindered widespread industrial electrification. Company executives have emphasized that industrial customers prioritise solutions that deliver reliable economics alongside emissions reductions, a combination that Enerin’s modular heat pump is engineered to achieve.
In addition to scaling manufacturing, the company plans to use part of the Series A capital to grow its commercial and engineering teams, further strengthening its ability to serve international markets and support customers through installation and long-term operation. Enerin also aims to continue innovating within its technology platform, keeping pace with evolving industrial needs and expanding the operational range of its systems.
The €15 million investment positions Enerin among a growing number of European clean-tech companies securing significant capital at the Series A stage, reflecting broader investor appetite for climate solutions that combine hardware, industrial-scale production, and measurable environmental impact. As industries worldwide set increasingly ambitious net-zero targets, technologies like high-temperature heat pumps are expected to play a pivotal role in enabling deep decarbonisation where electrification has historically been difficult.
Enerin’s funding success thus highlights a convergence of industrial demand, investor confidence, and technological readiness — key ingredients for scaling climate tech innovation from early adoption into mass industrial deployment. With capital and strategic backing now in place, Enerin is positioning itself to accelerate its transition from technology pioneer to industrial-scale provider of decarbonised heat solutions for global markets.
