The Kotka Project

Arctic Sisu’s first state-of-the-art e-methane production facility is located in Kotka, Southern Finland.

Project Overview

The Kotka project is a planned industrial-scale e-methane production facility located in Southern Finland. It combines renewable hydrogen production with captured biogenic CO₂ to generate drop-in compatible renewable gas for European energy markets.

Project Scope

The project is designed to integrate with local industrial infrastructure, enabling the use of biogenic CO₂ streams and efficient energy exchange. The facility is intended to operate at large scale, supporting the production of renewable methane that can be used within existing gas systems without modifications.

What We Have Done

  • Developed the initial concept for a large-scale e-methane production facility in Kotka.
  • Identified integration opportunities with local industrial CO₂ sources.
  • Defined a phased development approach for scalable implementation.
  • Engaged with stakeholders around industrial energy integration and feasibility.

Project Approach

The Kotka project follows a circular energy model where renewable electricity is used to produce green hydrogen via electrolysis. This hydrogen is combined with captured biogenic CO₂ from nearby industrial processes to synthesize renewable methane through methanation.

The approach emphasizes:

  • Industrial integration
  • Efficient use of existing infrastructure
  • Circular carbon utilization
  • Scalable deployment in phases

Results

The project is currently in development and planning stages. When operational, it is expected to produce large-scale volumes of renewable methane (in the range of ~900–950 GWh annually in full-scale configuration), contributing to the decarbonization of industrial energy use and transport fuels.

Final Thoughts

The Kotka project represents a key step in demonstrating how renewable hydrogen and captured CO₂ can be combined into scalable, infrastructure-ready energy solutions. It highlights the potential of industrial collaboration in accelerating the transition toward carbon-neutral energy systems.
