Decarbonizing energy with scalable e-methane solutions.
Integrating hydrogen, CO₂ capture, and methanation into scalable energy systems.
• 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.
Our e-methane plants are co-located with industrial partners to utilize biogenic CO₂ and exchange energy streams such as heat, steam, and oxygen, creating efficient circular energy systems.
E-methane is chemically identical to natural gas, allowing it to be transported, stored, and used within existing gas infrastructure without requiring new systems.
Utilization
Captured biogenic CO₂ is used as a key feedstock, turning industrial emissions into a valuable resource within a circular carbon cycle.
Our modular plant design enables efficient scaling, supporting large-scale implementation and accelerating emissions reduction across industries.
• 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.

Renewable methane can directly substitute fossil natural gas in existing pipelines and energy systems.
Biogenic carbon dioxide from industrial processes becomes a valuable feedstock for renewable fuel production.
E-methane allows renewable electricity to be stored and transported through existing gas infrastructure.
Our plants exchange energy streams such as heat, steam, and oxygen with nearby industries, increasing overall system efficiency.
• 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.
