The start-up Sakowin, which specialises in hydrogen production via methane plasmalysis, has partnered with V-Zug to help decarbonise the household appliance manufacturer’s operations.

After four years of research, Sakowin is moving into the industrial phase. Its technology, which combines plasma with a microwave generator, can produce low-cost, decarbonised hydrogen at scale. Plasma catalysis breaks down biomethane molecules without oxygen, generating hydrogen and solid carbon—both of which can be repurposed in other industries—all without CO₂ emissions.

Sakowin likens its process to a carbon atom filter. Crucially, it allows manufacturers to replace natural gas with hydrogen at a competitive cost.

“The demonstration of this industrial pilot is a major milestone for Sakowin,” said Gérard Gatt, the company’s founder and chairman. “The next challenge is to optimise energy consumption to 10 kWh per kilogram of hydrogen, enabling us to scale up.” The company aims to roll out additional pilot projects in 2026.

With 4 kg of natural gas, the plasmalysis process can produce 1 kg of hydrogen and 3 kg of solid carbon. Using a 100 kW reactor, Sakowin can currently generate 200 kg of hydrogen per day. By 2027, with multiple units in operation, production is expected to reach several tonnes per day.
