30 million euros in Series A for Spark Cleantech

Spark Cleantech has successfully completed its Series A financing and raised a total of EUR 30 million, including EUR 17 million in equity. The round was led by 360 Capital and Taranis. The Île-de-France Reindustrialization Fund (initiated by the Île-de-France region and operated by Innovacom), Asterion Ventures and existing investors were also involved.

The company is developing a new process that replaces the combustion of fossil fuels in high-temperature furnaces and in material production with a completely CO₂-free, economically competitive alternative. This can be done without major adjustments to existing industrial processes.

The fresh funding will accelerate the scaling of the company. Spark Cleantech intends to use it to finalize and operate its first production module and then roll it out to industrial customers. At the same time, the first commercial carbon products, one of the two materials produced by pulsed plasmolysis, will be qualified. The team is growing by around 20 specialists in sales, engineering and R&D.

This investment now enables the scale-up that industrial companies need to cost-effectively reduce their CO₂ emissions and commercialize the technology.

An international high-performance team

The founders Erwan Pannier (PhD, CentraleSupélec) and Patrick Peters (former CEO of Suez BioEnergies) have built a multidisciplinary team of experts with both technological and industrial expertise. The development is also supported by globally recognized specialists - including a Nobel Prize winner in physics, a former R&D director of Aramco and a former R&D director of Hutchinson.

The decarbonization of heavy industry is one of the key challenges of the coming decades and cannot be implemented without economic viability. Spark Cleantech combines entrepreneurial vision with industrial expertise and delivers a technology that addresses precisely this challenge.

85% fewer emissions, two CO₂-free materials and four times the economic value

Spark Cleantech's modules are connected between an industrial customer's existing gas network and its high-temperature burner. Pulsed plasma energy is used to remove the carbon from the gas, leaving pure hydrogen as a fully decarbonized energy source.

The separated carbon is further processed into a high-quality nanostructured material that is used in polymer and battery production, among other things. This CO₂-free carbon replaces a petroleum-based material with a very high emission profile.

The process, initially developed at Stanford University, further refined at CentraleSupélec and industrially implemented by Spark Cleantech, minimizes the energy required for separation while generating a valuable by-product.

In practical terms, this means that a fossil fuel is converted into two CO₂-free materials without combustion, quadrupling their combined economic value. Industrial companies in metallurgy, glass production, polymer production and battery manufacturing are already testing the technology.

Series module

Spark Cleantech's modules are installed directly at gas consumers in industry and enable the production of hydrogen at the point of use, without transportation or large-scale storage. The solid carbon is collected and passed on to processing industries.

Several major industrial partners are in advanced talks and initial contracts have been signed. Delivery of the commercial units is planned for 2027.

The startup was founded in 2022 in the laboratories of CentraleSupélec and is developing an emission-free alternative to fossil fuel combustion in energy-intensive industries (glass, metal, polymers, batteries). Based in the Paris-Saclay innovation cluster, the company employs an international team of experts and has raised 34 million euros since its foundation. It is supported by the "21st by CentraleSupélec" accelerator, among others.
