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 (P2G) 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.
Power-to-x technologies change electricity to another form of energy. Carbon dioxide and hydrogen are needed as raw materials. The manufacturing process is carried out with renewable electricity. Power-to-x-technologies are believed to play a key role in climate change management and the ongoing energy transition, as they allow synthetic electric fuels produced to replace fossil fuels in cars, ships, air transport and energy production without hardware changes.
