Neovolt and Woikoski are making Finland a forerunner of green hydrogen

Mediatiedote suomen kielellä

Neovolt Oy and Woikoski Oy are determined to make Finland a pioneer in the field of green hydrogen. The first joint project has now been successfully completed. This work allowed us to identify several ways of improving energy efficiency of the green hydrogen production using water electrolysis.

Neovolt has analyzed three hydrogen production lines of Woikoski in Kokkola. Based on the project results, Neovolt together with Woikoski identified measures to improve the current hydrogen production process efficiency and possibly extend the lifetime of the deployed water electrolysers.

An essential competitive factor for a hydrogen producer is the understanding of the usage of electrical energy in the production process. This means identification of the process losses and an optimization potential.  The extensive measurements of the hydrogen production plant carried with Neovolt and deep analysis of the results have significantly increased our understanding of the production process and provided a solid basis for the investment preparation, comments Mr. Olli Bergmann, Woikoski Technical Director, on the project results.

The project has been successfully completed. We achieved our objectives of providing Woikoski a more accurate picture of their hydrogen production process. Moreover, we improved Neovolt’s expertise in the industrial-scale hydrogen production and its requirements. Based on the achieved results, we will continue cooperation in the future, says Neovolt CEO Mr. Samuli Räisänen.

The war in Ukraine creates further pressure for reduction of fossil fuels

The demand forecasts for the growth of green hydrogen have been promising for years. Now, replacing fossil fuels is even more important because due to the war in Ukraine natural gas and oil prices are rising and the availability of them in long term is uncertain.

Finland is in key position to become a forerunner in development and production of green hydrogen technologies. There is advanced research and business in the field of green hydrogen and green hydrogen has been produced in Finland for decades. Hydrogen is expected to revolutionize the whole society and especially the energy sector.

Green hydrogen is emission free. It is produced with renewable electricity generated with, for example, wind or solar power. Therefore, green hydrogen production and usage do not cause carbon emissions. This process is overall called Power-to-X -technologies where electricity is converted to another energy carrier. Green hydrogen is produced with water electrolysis, where water is split into oxygen and hydrogen. Green hydrogen can be directly used in replacing natural gas in various heavy industrial processes such as steel and fertilizer production. When green hydrogen is used as a fuel in fuel cells, it is converted back into electricity and the only emission is water.
