About Spark Cleantech
Developer of a plasma technology designed to turn greenhouse gases into hydrogen fuel. The company's technology follows a process called plasmolysis that uses cold pulsed plasma discharges to convert methane or carbon dioxide and methane mixtures into value-added products such as hydrogen, solid carbon, and carbon monoxide, which offers competitive hydrogen, produced directly on the consumption site, as a substitute for fossil gas to decarbonize industrial heat, enabling the transport industry to have carbon-neutral hydrogen fuel.
