P2X Solutions Oy Solutions has awarded Sunfire a contract to conduct the Front-End Engineering Design (FEED) study for a 40 MW hydrogen project in Joensuu, Finland. The new project builds on the success of the companies’ previous collaboration at P2X Solutions’ Harjavalta facility, where Finland’s first industrial-scale green hydrogen production was achieved earlier this year.

At the start of the year, P2X Solutions and Sunfire marked a historic milestone with the first industrial-scale green hydrogen production in Finland’s energy history. Building on this achievement, the two hydrogen pioneers are now further strengthening their partnership:

Sunfire has been selected by P2X Solutions to conduct the Front-End Engineering Design (FEED) study for the 40 MW hydrogen project in Joensuu, Finland. For this project, P2X Solutions is continuing to leverage the German electrolysis specialist’s industrial pressurised alkaline technology. The companies announced the ongoing collaboration today at the World Hydrogen Congress in Copenhagen. Herkko Plit, CEO of P2X Solutions, underlines: “The FEED study is an important milestone towards the investment decision of our next undertaking in Joensuu, which will triple our total capacity for green hydrogen production. We are very pleased to tackle this challenge together with Sunfire and its technology.”

Nils Aldag, CEO of Sunfire, states: “The commissioning of the Harjavalta plant showcased the strong execution capabilities of P2X Solutions and Sunfire in delivering commercial hydrogen projects. I’m excited that we are now taking our partnership to the next level in Joensuu — as a trusted technology partner alongside P2X Solutions, with a clear mission: to drive the growth of the hydrogen economy in Finland and Europe.”

Milestone for project implementation

Sunfire has already started the comprehensive FEED study, which, in close collaboration with the integration partners, defines the requirements and prerequisites for a 40 MW pressurised alkaline electrolyser. The outcome of the study represents a key milestone on the path to project realization and ensures effective implementation.

In Joensuu, the green hydrogen produced by the electrolysis plant will later be used to produce e-methanol — a synthetic fuel that plays a key role in reducing CO2 emissions, particularly in the shipping and aviation industries.

Shared vision

The collaboration between Sunfire and P2X Solutions reflects a pioneering spirit, hands-on hydrogen expertise and strong commitment to delivering results. A standout result of the close collaboration between the two companies is the successful commissioning of the 20 MW plant in Harjavalta. For the first time in Finland, an industrial-scale green hydrogen plant entered commercial operation, marking a historic milestone for the hydrogen market both nationally and across Europe. Alexander Stubb, President of the Republic of Finland, personally recognised the accomplishment and congratulated the partners involved.

At the Harjavalta plant, P2X Solutions relied on Sunfire’s pressurised alkaline technology — a proven solution recognised for its reliability, efficiency, and strong performance. With the new project in Joensuu, both companies aim to build on this success and continue their collaboration.

What is alkaline water electrolysis?

A hydrogen plant using pressurized alkaline technology employs alkaline water electrolysis in a high-pressure system to produce hydrogen and oxygen from water, with elevated operating pressure reducing the need for mechanical gas compressors, thereby increasing system efficiency and integration with renewable energy sources.

Stainless steel in pressurized alkaline H2 plants

In a pressurised alkaline hydrogen plant, stainless steel is used in electrolyser components like bipolar plates and endplates, in Balance of Plant (BOP) equipment including pressure vessels, tanks, and separators, and in water treatment systems to ensure high purity for the electrolysis process. High-performance austenitic or duplex stainless steel grades are chosen for their high strength, excellent corrosion resistance to high-pressure hydrogen and caustic environments, and formability.

About P2X Solutions

P2X Solutions is a Finnish pioneer in green hydrogen and Power-to-X technology. It is accelerating the rise of the hydrogen market in all areas of the value chain, and has built Finland’s first industrial-scale green hydrogen and synthetic methane production plant in Harjavalta. P2X operates as a producer and distributor of green hydrogen and synthetic fuel, and supplies hydrogen plants on a turnkey basis.

About Sunfire

Sunfire is leading producer of industrial electrolysers based on pressurised alkaline and solid oxide (SOEC) technologies. With its electrolysis solutions, Sunfire is addressing a key challenge of today’s energy system: Providing renewable hydrogen and syngas as climate-neutral substitutes for fossil energy.
