    Behind Spark Cleantech are two co-founders with complementary expertise:

    • Erwan Pannier, PhD CentraleSupélec, specialist in plasmalysis and energy.

    • Patrick Peters, former CEO of Suez BioEnergies, seasoned entrepreneur in industrial transitions.

    They have assembled around them an international multidisciplinary team, recognized for its ability to deliver both cutting-edge research and industrial execution.
    ‍
    The company also relies on an exceptional scientific advisory board, including a Nobel Prize winner in Physics and former R&D directors from Aramco and Hutchinson. This level of excellence reassures manufacturers engaged in a complex transformation: decarbonization without operational disruption.

    "Decarbonizing heavy industries is a major challenge. If it isn't economically viable, it won't happen. In Spark Cleantech, we've found a pragmatic solution and a team that fully understands the industrial challenges.“— Thomas Nivard, Partner, 360 Capital.

     

    A technology unique in the world: pulsed plasmalysis

     

    Spark Cleantech relies on a unique innovation: pulsed plasmalysis, developed at Stanford, further refined at CentraleSupélec, and then industrialized in France. The process is easily integrated between the gas network and industrial burners, where it separates methane without combustion using a pulsed plasma.
    ‍
    This reaction produces two decarbonized materials: clean hydrogen, immediately usable, and a solid carbon nanomaterial with high added value, capable of replacing petroleum-based materials.
    ‍
    The result: an 85% reduction in emissions and a fourfold increase in economic value.

    Already tested by several manufacturers in the metallurgy, glassmaking, polymers and battery industries, the technology demonstrates simple integration, stable performance and real potential for massive deployment.
