The technology group Wärtsilä and Finnish utility Vantaa Energy Ltd have signed a co-operation agreement for pre-engineering and development of a Power-to-Gas plant for Vantaa Energy. The plant planned to be commissioned in 2025 would be the largest in Finland and also the first to produce carbon-neutral, synthetic methane on a commercial scale with a fuel capacity of 10 MW. Synthetic methane is produced from captured carbon dioxide and hydrogen produced with renewable energy. In May 2020, the parties signed a co-operation agreement for a concept study examining the profitability of the Power-to-Gas plant in connection with the Vantaa Energy waste-to-energy plant. The decision to continue the project is based on the outcome supporting the further planning and development of the study.

Wärtsilä will lead the pre-engineering phase of the project. Once completed, the project will produce synthetic methane from renewable electricity sources by extracting hydrogen from water, as well as extract CO₂ out of emissions from an existing waste to energy plant. The resultant methane will be sufficient for use in up to 200 trucks per day, and replace conventional, fossil natural gas in district heating during heating peaks in winter.

The EU has set a common target of climate neutrality by 2050, and has recently raised its emissions reduction target to 55% by 2030. Finland aims for carbon neutrality by 2035. The plant will represent a crucial step in Vantaa Energy’s decision to be fossil-free by 2026. Phasing out the use of fossil fuels utilising versatile technologies is an important enabler for carbon-neutral Vantaa Energy in 2030. The Power-to-Gas plant will allow Vantaa Energy to start using electricity produced from renewable sources for reducing CO₂ emissions in district heating, other applications where gas is used, and transportation. The project demonstrates sector coupling of heat, electricity and transportation, which provides Vantaa Energy completely new business opportunities.
