Sweden-headed international engineering and architecture consultancy firm Sweco Group has announced that it has been selected by Finnish municipal energy company Helen Oy as Engineering, Procurement, and Construction Management (EPCM) partner in the implementation of its first production plant for green hydrogen.

Helen is one of Finland’s largest energy operators and has worked with Sweco for many years. For example, Sweco has been an 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 a capacity of approximately 3 MW.

Production of hydrogen is set to start in 2026, to supply the heavy-duty transport sector. The excess heat from production will be utilized in Helen’s district heating network and is expected to increase the plant’s energy efficiency to over 90 percent.

Sweco has extensive experience of working as an advisor and EPCM partner to Helen and we have joint operating methods in place for smooth project delivery. This successful cooperation is now being extended to include Sweco’s considerable expertise in hydrogen, gained from numerous projects in Finland and across Europe. It is fantastic to continue together towards achieving Helen’s carbon neutrality targets, as part of the ongoing green transition, said Thomas Hietto, Business Area President of Sweco Finland.

As an 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 electrolyzer and related equipment are designed, supplied, and installed by a different partner.

The 3H2 project is the first of its kind in the world and combines four different sectors: electricity, transport, heating, and hydrogen, and the flexibility between them. For Helen, hydrogen is an essential part of our new strategy, and we are committed to investing in the development of the hydrogen business. It is great to continue our smooth cooperation with Sweco by building Helsinki’s first green hydrogen production plant together, said Dr Sari Mannonen, SVP of New Business and Hydrogen at Helen.

Sweco supports its clients in the energy transition by bringing together expertise in areas of strategic importance for energy supply.

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