Spark Cleantech

Spark Cleantech is a French deeptech company founded in 2021 and based in Gif-sur-Yvette.

It specializes in developing and operating on-site systems that convert (bio)methane into decarbonized hydrogen and solid carbon materials. The company utilizes a patented methane plasmalysis process that employs non-thermal, cold pulsed plasma to separate methane without combustion, resulting in clean hydrogen and carbon black. The company designs and operates modular hydrogen production units tailored for industrial clients, providing a cost-effective solution for decarbonization. Spark Cleantech aims to replace fossil gas in industrial processes, significantly reducing emissions by approximately 85%. Its technology is particularly relevant for heavy industry and carbon-free heavy mobility, with applications in sectors such as metals, glass, polymers, and batteries. Spark Cleantech has raised over €34 million in funding and is positioned as a scalable alternative for industrial decarbonization.
