Finnish energy company Helen has selected Sweco as EPCM partner in the implementation of its first production plant for green H₂. Production of H₂ is set to start in 2026, with the aim of supplying 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%.

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 H₂ Hub is Helen’s first H₂ investment and it will be a pilot plant with the capacity of approximately three megawatts.

“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 H₂, gained from numerous projects in Finland and also 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 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 H₂, and the flexibility between them. For Helen, H₂ is an essential part of our new strategy, and we are committed to investing in the development of the H₂ business. It is great to continue our smooth cooperation with Sweco by building Helsinki’s first green H₂ production plant together,” said Sari Mannonen, SVP, New Business and H₂ of Helen.
