Spark develops local production sources of clean hydrogen.



Our proprietary technology, unique worldwide, uses non-thermal plasmas to convert (bio)methane into hydrogen and carbon black. This results in a zero or negative carbon footprint for hydrogen production, with a very low electricity requirement.



Spark aims to produce hydrogen directly on site through its modular system and addresses the need for a cost-effective source of clean hydrogen for industry and carbon-free heavy mobility.



Today, we are on the way to deploy industrial pilots to prepare commercialization.
