Decarbonizing energy with scalable e-methane solutions.
Utilizing renewable power to reduce the European climate impact
• About Us
Arctic Sisu develops industrial-scale e-methane production facilities in Finland.
By combining green hydrogen and captured biogenic CO₂, we produce a fully drop-in compatible renewable gas that can replace fossil natural gas all around the world. Our team brings innovation and sustainability together to deliver scalable energy solutions.
brings value
Our e-methane plants are co-located with industrial partners to utilize their biogenic CO₂ emission and to exchange energy streams such as heat and steam, as well as oxygen, creating efficient circular energy systems. Industrial integration not only enables cost-effective production of renewable synthetic fuels but also improves the sustainability and business of our industrial partners.
E-methane is chemically identical to natural gas, allowing it to be transported, stored, and used within the existing gas infrastructure without requiring investments into new transport pipelines or storage systems. E-methane can be liquefied into e-LNG similarly as natural gas is liquefied and e-LNG can be used as fuel identically to fossil or bio LNG.
The compatibility of e-methane with the existing infrastructure and applications enables users to transition from fossil natural gas or LNG into sustainable renewable e-methane or e-LNG quickly. Trade of e-methane or e-LNG can take place over the European gas market based on mass balance of gas and trading of gas certificates. No new investments are needed for transport and use of e-methane, and end-use can be scaled-up as needed when the regulatory mandates for emission reductions tighten.
Utilization
Captured biogenic CO₂ is used as a feedstock, turning industrial emissions into a valuable resource within a circular carbon cycle.
Despite being called “decarbonization”, carbonaceous fuels and chemicals are still needed in many applications in the transport, energy and industry sectors. E-methane production utilizes biogenic CO2, which would otherwise be emitted to the atmosphere from existing industrial processes, as a feedstock. In this way, the atmospheric carbon cycle is closed and when the produced e-methane is used to replace fossil natural gas, also fossil CO2 emissions are directly reduced. As a by-product, a new value chain is built around industrial CO2 emissions, benefitting both the climate as well as the industry.
Deployment
Arctic Sisu's plant design has since day one focused on scalability, cost-effectiveness and operational effectiveness. Our experience in engineering production facilities based on process technologies from industry-leading equipment vendors ensures that our plants are cost-effective and compatible with the local industrial environment, the infrastructure as well as the prevailing power grid conditions. Through experience and close collaboration with equipment vendors and engineering partners, our plants will only get better as we build more of them.
• The Problem
The world needs scalable decarbonization solutions.
Many sectors, including heavy industry, marine transport, and heating, still rely heavily on fossil natural gas. Electrification alone cannot fully decarbonize these sectors. Renewable gas solutions that integrate with existing infrastructure are essential to accelerate the energy transition.
Sustainable Impact
Each plant reduces fossil fuel dependence and contributes to a carbon-neutral energy transition.
Circular Energy Use
Our plants integrate with industrial operations to capture and reuse by-products like heat, steam, and oxygen, maximizing efficiency and sustainability.
CO₂ Capture
Biogenic CO₂ from industrial processes is captured and used as feedstock.
Methanation
Hydrogen reacts with CO₂ to produce renewable methane compatible with existing gas infrastructure.

• FAQ
Frequently asked questions.
E-methane is a synthetic renewable gas produced by combining green hydrogen with captured carbon dioxide. The resulting methane molecule is chemically identical to natural gas but can be produced with significantly lower lifecycle emissions.
E-methane is produced using renewable electricity, hydrogen generated through electrolysis, and captured carbon dioxide. Hydrogen reacts with CO₂ in a process called methanation, producing renewable methane that can be used in existing gas infrastructure.
Many sectors still rely on natural gas for energy and heat. E-methane provides a renewable alternative that can be transported and used within existing pipelines and energy systems, enabling faster decarbonization.
