Helen has selected Sweco as EPCM partner in the implementation of its first production plant for green hydrogen. Production of hydrogen is set to start in 2026, with the aim of supplying the heavy-duty transport sector. The excess heat from production will be utilised in Helen's district heating network and is expected to increase the plant's energy efficiency to over 90%.

Helen is one of Finland's largest energy operators and has worked with Sweco for many years. For example, Sweco has taken the role of Engineering, Procurement, and Construction Management (EPCM) partner in several heating and cooling plant projects. The new 3H2 Helsinki Hydrogen Hub is Helen's first hydrogen investment and it will be a pilot plant with the capacity of approximately three megawatts.

As EPCM partner, Sweco is responsible for planning the project's regional infrastructure, including architectural, structural engineering and plant design, as well as project management, procurement and site management services. The electrolyser and related equipment are designed, supplied, and installed by a different partner. In the energy transition, Sweco supports its clients by bringing together expertise in areas of strategic importance for energy supply.

These range from renewable energy production, expansion of the electricity transmission and distribution grid, efficient energy consumption, and technological development in areas such as hydrogen energy storage, carbon capture and storage (CCS) and carbon capture and utilisation (CCU).
