This is a rare, conviction-sized bet on European industrial decarbonisation because it backs heavy hardware at the exact point where most investors hesitate: the jump from pilot to commercial delivery.
Dutch company RIFT has raised EUR 113.8 million in funding to scale its Iron Fuel Technology, a system that uses iron powder as a circular energy carrier to generate high-temperature industrial heat without direct CO₂ emissions. The round was led by pension investor PGGM, which committed EUR 83.1 million, alongside Invest-NL, Oost NL, Rubio Impact Ventures, Brabantse Ontwikkelings Maatschappij (BOM) and Energietransitiefonds Rotterdam.
The financing was described as one of the largest investments in a Dutch sustainable energy company in recent years. That scale matters: RIFT is not funding another demonstration unit. It is funding the operational reality of commercial production, supply chain build-out and first-of-a-kind execution risk.
Why this round stands out
Cleantech funding has been selective, and hardware-heavy decarbonisation plays typically face a tougher path than software-led climate solutions. RIFT’s Series B is therefore notable not just for its size, but for who wrote the cheques.
A pension-led round signals appetite for long-duration, infrastructure-like decarbonisation assets, provided the technology has a credible route to deployment. The participation of national and regional development finance institutions reinforces that this is being treated as strategic industrial capability, not a speculative science project.
RIFT has also secured a EUR 30.7 million EU Innovation Fund grant, awarded under a highly competitive process for large-scale decarbonisation projects. While grants do not eliminate execution risk, they materially improve the capital stack and indicate policy-aligned validation.
What RIFT is selling: heat, not a lab concept
Industrial heat is one of the hardest parts of the energy transition. Sectors such as food processing, chemicals and building materials still rely heavily on fossil fuels, particularly natural gas. Industrial heat demand is large, continuous and often requires high temperatures, making electrification and fuel switching complex.
RIFT’s Iron Fuel Technology burns iron powder to produce heat. The process emits no direct CO₂ at the point of use. The resulting iron oxide is then regenerated back into iron in a closed-loop circular system, effectively using iron as a reusable energy carrier.
The commercial proof point is crucial. RIFT’s first commercial deal is with Kingspan Unidek, where an iron fuel boiler is expected to deliver 340 GWh of heat annually. Over 15 years, the project is expected to avoid more than 1 million tonnes of CO₂. RIFT has also positioned the solution as requiring minimal changes to existing infrastructure, an important adoption lever in industrial sites where downtime and retrofits are expensive.
Strategic read-through for investors and buyers
The strategic logic is straightforward: if RIFT can deliver reliable, high-temperature heat with a circular fuel loop, it becomes a scarce asset in Europe’s decarbonisation toolkit.
- A defined first commercial deployment with quantified heat output and emissions impact, moving the story from potential to contracted delivery.
- Institutional capital leadership (PGGM) alongside public finance, supporting the longer timelines and capex intensity typical of industrial energy infrastructure.
- A focus on hard-to-abate heat, where the value of decarbonisation options is higher because alternatives are limited.
Risks that will decide the outcome
This round buys RIFT time and industrialise-or-die runway. The key risks are execution, not awareness:
- Scale-up and reliability: moving from pilot systems to commercial uptime at industrial duty cycles.
- Fuel loop economics: the cost and energy intensity of regenerating iron oxide back to iron will determine whether the model competes at scale.
- Supply chain and permitting: building production capacity and operating within safety and regulatory requirements for powder handling and industrial combustion.
If RIFT can deliver the Kingspan Unidek project and replicate it across similar heat users, the company will have done what much of European climate tech has struggled to do: turn an elegant decarbonisation concept into repeatable industrial infrastructure.
