ROTOBOOST, a Finnish company developing technology for the energy transition, has taken on a strategic investment from Aramco Ventures, the corporate venture capital arm of Saudi Aramco. The size of the investment was not disclosed.
The Helsinki-based startup plans to use the capital to scale up its methane pyrolysis technology. The process breaks down methane and other hydrocarbons into two outputs: low-carbon hydrogen and solid carbon materials, including graphene.
The deal was reported by Graphene-Info, which covers developments in the graphene and advanced materials sector.
How ROTOBOOST's Methane Splitting Works
ROTOBOOST describes its approach as thermal-catalytic decomposition. The method relies on a molten catalyst to separate hydrocarbon molecules into hydrogen and carbon without producing carbon dioxide in the way conventional methods do.
According to the company, the process generates far fewer emissions than steam methane reforming, the dominant way hydrogen is made today. It also claims the technology requires less energy than producing hydrogen by splitting water through electrolysis.
Turning Solid Carbon Into a Revenue Stream
A central part of the company's pitch is that the carbon byproduct is not waste. ROTOBOOST sells it as graphene nanoplatelets, which it characterizes as crumpled, three-dimensional sheets containing meso- and macropores.
The company argues that selling this material links decarbonization directly to revenue, a business model that could help offset the costs of clean hydrogen production. For the material, ROTOBOOST cites a volume resistivity of 0.003 Ω·cm and a BET surface area of 22 m²/g.
Target Markets for Graphene Nanoplatelets
ROTOBOOST lists a broad set of potential uses for its nanoplatelets. These include battery electrodes and conductive additives, concrete additives, tire reinforcement and coatings and polymers.
The company also sees a role for its carbon in heavy industry, specifically as a replacement for coal-based carbon in steel and aluminum production. It says it is already working with Hankook Tire on carbon materials for tires and with Chinese steelmaker Baowu on natural gas splitting for green steel.
Where the New Funding Will Go
The investment is earmarked for manufacturing commercial-scale methane pyrolysis systems and for increasing output of the company's carbon materials.
It will also support geographic expansion across the Middle East, Europe, Asia and North America. ROTOBOOST currently has its headquarters in Helsinki and operates offices in China and Malaysia.
What the Deal Signals for Energy Transition Startups
The investment reflects continued interest from major oil and gas companies in technologies that can reduce emissions from natural gas use rather than replace it outright. Methane pyrolysis offers one route for producers to keep using existing hydrocarbon resources while lowering their carbon footprint.
For founders in climate tech, ROTOBOOST's model highlights the appeal of pairing decarbonization with a sellable byproduct. Whether graphene markets can absorb large volumes of material at scale will be a key test as the company moves from development toward commercial deployment.
