What Coolbrook does
Coolbrook is a Finland-based industrial technology company founded in 2011 that has developed and patented RotoDynamic Technology (RDT), a rotating turbomachinery platform that generates process heat up to 1700°C entirely from electricity, replacing fossil-fuel combustion in hard-to-abate heavy industries. The platform is commercialized in two product lines: the RotoDynamic Heater (RDH) for high-temperature process heating in cement, steel, iron, aluminum, and chemicals, and the RotoDynamic Reactor (RDR) for electrified steam cracking of hydrocarbons to produce olefins (ethylene, propylene). Coolbrook claims it is the only electric technology able to reach 1700°C, with claimed efficiency benefits of ~30% energy reduction and up to 20% higher ethylene yields versus conventional processes, and has demonstrated 100% plastic-waste-derived pyrolysis oil cracking at its large-scale pilot at Brightlands Chemelot Campus, Geleen, Netherlands.
The company's business model combines technology licensing, bespoke equipment supply, and engineering services, sold through direct enterprise sales to large industrial producers. It operates a partner ecosystem of tier-1 engineering and manufacturing firms — ABB (automation), Linde Engineering (RDR plant integration), Tenova (metals), Doncasters (precision castings), Trac Precision Solutions (machining), and Schmidtsche Schack/Arvos (transfer line exchangers) — and has signed cooperation agreements with major customers including Adani Group, JSW, UltraTech, CEMEX, SABIC, Braskem, Shell, and ArcelorMittal. The first commercial RDH unit was delivered to Adani Cement's Boyareddypalli plant in India in November 2025, marking the transition from pilot to commercial rollout. Funding to date is limited to a 5.5 million EUR Dutch government grant and 7 million EUR from Finnish private investors supporting a ~12.5 million EUR pilot program; the firm is privately held with offices in Finland, the Netherlands, India, and the United Kingdom.
Headcount is listed at 1–10 in firmographics, which understates apparent operating scope across multiple countries; this discrepancy should be flagged by any investor. Coolbrook's growth strategy is anchored on multi-plant frameworks with anchor customers (e.g., Adani Group's stated ambition of 5+ additional projects within two years) and on expanding the RDR pipeline beyond naphtha into circular plastics feedstocks.

Coolbrook product offering
Product offeringCore offering
Coolbrook develops and sells RotoDynamic Technology, a patented rotating turbomachinery platform that generates high-temperature process heat up to 1700°C using renewable electricity to replace fossil-fuel combustion in hard-to-abate heavy industries. The company delivers two main product applications — the RotoDynamic Heater (RDH) for high-temperature industrial process heating (cement, steel, chemicals) and the RotoDynamic Reactor (RDR) for electrified steam cracking of hydrocarbons into olefins. Revenue is generated through technology licensing fees, equipment sales, and engineering integration services to large multinational industrial customers.
Product overview
Coolbrook offers the RotoDynamic Technology platform with two main product applications: the RotoDynamic Reactor (RDR) for electrified steam cracking in the petrochemical industry to produce olefins (ethylene, propylene) without CO2 emissions, and the RotoDynamic Heater (RDH) for electrified high-temperature process heating across cement, iron and steel, aluminum, chemicals, and pulp and paper industries. Both products use the same patented rotating turbomachinery technology to generate heat up to 1700°C using renewable electricity. The company operates a large-scale pilot facility in the Netherlands for technology validation. The RDH achieved its first commercial deployment at Adani Cement in India in November 2025.

Coolbrook competitors and assessment
Company assessmentDirect peers
- Rondo Energy: Rondo Energy provides industrial heat decarbonization solutions using electric heat battery technology and industrial heat electrification for hard-to-abate sectors. It is a direct competitor in electrifying high-temperature process heat for cement, steel, and chemicals, mirroring Coolbrook's RDH value proposition.
- Heliogen: Heliogen develops concentrated solar thermal technology to deliver carbon-free high-temperature heat for industrial processes. It targets the same hard-to-abate industrial heat market as Coolbrook's RDH, focusing on high-temperature process heating above 1000°C for cement, steel, and petrochemical applications.
- Electrified Thermal Solutions (ETS): ETS (formerly known as Joule Unlimited) is developing Joule-heated thermal storage and electrified industrial process heat for hard-to-abate industries. It is a direct competitor to Coolbrook in providing high-temperature electrified heat solutions for industrial decarbonization.
Emerging players
- Boston Metal: Boston Metal is commercializing molten oxide electrolysis for primary steelmaking, directly targeting decarbonization of the steel industry. Like Coolbrook's RDH for steel applications, Boston Metal offers an electrified alternative to fossil-fuel-based blast furnace and DRI processes.
- Sublime Systems: Sublime Systems is developing electrified cement production technology that eliminates CO2 emissions from cement manufacturing. Like Coolbrook's RDH for cement calcination, Sublime targets the same cement industry decarbonization opportunity with a different electrified process route.
- Sunfire: Sunfire develops high-temperature electrolyzer technology for green hydrogen and synthetic fuels, serving hard-to-abate industrial sectors. While focused on hydrogen rather than direct electrification like Coolbrook, it competes for the same industrial decarbonization budget at petrochemical and steel customers.
- CarbonCure: CarbonCure Technologies provides carbon dioxide utilization technology for the concrete and cement industry. While focused on carbon capture rather than electrification, it competes with Coolbrook's RDH for cement industry decarbonization budgets and customer mindshare among major cement producers.
Broad incumbents
- Linde: Linde is a global industrial gases and engineering company and a key Coolbrook partner for RDR plant integration. As a broad incumbent serving petrochemical and industrial customers worldwide, Linde could both enable and ultimately compete with Coolbrook's electrified cracking technology at scale.
- Siemens Energy: Siemens Energy is a global leader in turbomachinery, power generation, and industrial electrification. With deep expertise in gas turbines and rotating equipment, it represents both a potential incumbent competitor and a partner channel for high-temperature industrial electrification solutions like Coolbrook's RotoDynamic Technology.
- ABB: ABB is a global leader in industrial automation, electrification, and motion, providing motors, drives, and control systems. As a Coolbrook technology partner for RDH/RDR systems, ABB could potentially develop or acquire competing electrified industrial heat solutions.
