3H2 – Helsinki Hydrogen Hub
We are building a hydrogen production plant in Vuosaari, Helsinki. This is Helen’s first hydrogen project with which we will increase our expertise to meet the needs of large-scale hydrogen production and enhance the flexibility to the entire energy system. This is also the first plant for hydrogen produced using renewable electricity to be built in Helsinki. The aim is to launch the hydrogen production in the new plant in 2026.
We enhance the flexibility to the entire energy system
In the 3H2 plant, hydrogen will be produced with renewable electricity. This is the world’s first hydrogen project, which is designed to be an integral part of the optimisation of society’s overall energy system in the electricity, heat, transport and hydrogen markets as well as to serve as the solution for the flexibility of the energy system. The capacity of the 3H2 plant will be approximately three MW.
We produce renewable hydrogen for heavy transport
Reduction of emissions makes hydrogen produced using renewable electricity an attractive alternative especially for heavy transport in which electrification is challenging. The produced hydrogen will primarily be used through a hydrogen refuelling station to be built in connection with the plant, which is mainly intended for heavy transport. The refuelling station, slated for operation by 2027, aims to meet the EU's AFIR target standards.
Waste heat put to good use for Helsinki residents
The waste heat generated in the production process will be utilised in Helen’s district heating network, and the facility is planned to achieve an overall energy efficiency of over 90%. The plant will be located in the vicinity of Helsinki’s district heating network and the busy Vuosaari Harbour which enables the seamless utilisation of waste heat in Helsinki’s district heating network and the provision of hyrdogen-based fuel solutions for heavy transport.
