Helen to invest in Helsinki’s first green hydrogen production plant

In Finland, Helen said it will build a green hydrogen production plant in Vuosaari, Helsinki. The facility will be Helen’s first hydrogen project with which the company aims to increase its expertise to meet the needs of large-scale hydrogen production. The capacity of 3H2 – Helsinki Hydrogen Hub pilot plant project – will be approximately 3 MW. The produced hydrogen will primarily be used through a hydrogen filling station to be built in connection with the plant, which is mainly intended for heavy transport. The plant will be located in the vicinity of Helsinki’s district heating network and the  Vuosaari Harbour. The waste heat generated in the production process will be utilized in Helen’s district heating network, which means that the overall energy efficiency of the plant is over 90%, Helen said. “The 3H2 project is the first of its kind in the world, combining four different sectors: electricity, transportation, heating and hydrogen as well as flexibility between them. Hydrogen is an essential part of Helen’s new strategy and we are committed to investing in the development of the hydrogen business. We are excited to start building Helsinki’s first green hydrogen production plant,” said Sari Mannonen, SVP, New business and hydrogen. The aim is to launch the hydrogen production in the new plant in 2026 and open the filling station in 2027, the company said.
