Spark Cleantech is developing a process that replaces the combustion of hydrocarbons in high-temperature industrial furnaces and in materials production with an alternative that is not only fully decarbonised, but also economically competitive and requires only minimal adaptation to existing industrial processes.
The funding round will also support the qualification of Spark Cleantech's first commercial carbon grades, one of the two materials generated by pulsed plasmolysis. The company intends to expand its team with 20 new roles across commercial operations, engineering, and R&D.
“Following our seed round in the summer of 2023, we succeeded in deploying a first industrial pilot in under a year” said Patrick Peters, Co-Founder of Spark Cleantech. "We have validated clear market traction and assembled a world-class international team. This funding will enable the scale-up that industrial players are seeking to reduce their carbon footprint cost-effectively and to accelerate commercial deployment."
“The decarbonisation of heavy industry is one of the defining challenges of the decades ahead” added Thomas Nivard, Partner at 360 Capital. "But we must be candid: without economic viability, it simply will not happen. In Spark Cleantech, we found a team of entrepreneurs and industrial leaders who share this pragmatic view and who are delivering a technology that responds directly to it."
Spark Cleantech's modules are installed between the client's existing gas network and their high-temperature industrial burners. Through pulsed plasma, the technology removes carbon from the gas prior to combustion, leaving only hydrogen, a fully decarbonised energy source.
The extracted carbon is transformed into a solid nanomaterial, essential for polymers and battery manufacturing. Spark Cleantech's carbon, produced without emissions, replaces a petroleum-derived material with a high carbon footprint.
This is made possible through a world-unique technology. Initially invented at Stanford University in California, further developed at CentraleSupélec, and industrialized by Spark Cleantech in France, pulsed plasmolysis minimizes the energy required for separation while producing a high-value carbon nanomaterial.
In practical terms, pulsed plasmolysis converts a hydrocarbon, without combustion, into two decarbonised materials whose combined economic value is multiplied by four.
Spark Cleantech's technology is currently being tested by major clients across metallurgy, glassmaking, polymer production, and battery manufacturing.
The company's modules will be installed directly on industrial sites consuming natural gas, enabling hydrogen to be produced exactly where it is needed, without transport or large-scale storage. The solid carbon will be collected and routed to industrial sectors that use this nanomaterial.
Advanced discussions are under way with several industrial groups, and initial contracts have already been signed to prepare the deployment of commercial units in 2027.
