Hycamite produces clean hydrogen and industrial-quality solid carbon by splitting methane using proprietary zero-emission technology. It is based on the thermo-catalytic decomposition (TCD) of methane molecules — in other words, we break the methane with our catalyst and heat. The novel methane pyrolysis technology requires only 13% of the energy needed to produce hydrogen using electrolysis. Hycamite’s technology enables the production of low-carbon or even carbon-negative hydrogen. Hydrogen can be produced from biomethane, methane from natural gas, or synthetic methane. As a cutting-edge carbon capture, utilisation and storage (CCUS) technology, Hycamite’s solution enables the creation of carbon sinks, providing clients with industrial-quality carbon fit for demanding applications, such as Li-ion batteries, composite materials and filter purifiers. Hycamite’s production is environmentally friendly. There are no emissions into the atmosphere and the catalysts used are sustainable. Hycamite is a privately owned company headquartered in Kokkola, Finland.
