Switzerland’s first industrial Power to Gas (PtG) facility based on biological methanation, the plant serves as a landmark project supporting Switzerland’s Energy Strategy 2050.
By converting fluctuating renewable electricity into storable and transportable gas, the Dietikon PtG plant demonstrates how Power-to-Gas technology can strengthen energy security, support decarbonization, and set a precedent for future renewable gas projects across the country.

Solution
The facility uses renewable electricity from the WtX plant to produce hydrogen via electrolysis. This hydrogen is then combined with CO₂ from sewage gas in Kanadevia Inova Schmack’s bioreactor, where microorganisms convert the mixture into methane. After purification, the resulting green gas is fed into the local grid, providing a CO₂-neutral substitute for natural gas. The plant’s output enables annual CO₂ savings equivalent to the emissions of approximately 2,000 households.
