Renewable Methane from Your CO₂ — Biological, at 55 °C, in Containers.
METHANICA converts biogenic carbon dioxide and green hydrogen into renewable methane using naturally occurring methanogenic microorganisms. Standardized 20-ft modules, thermophilic at 55 °C, near-atmospheric pressure, load-flexible between 10 and 110 % — grid-injectable into the existing natural gas network.
The Challenge of Renewable Energy
Renewable energy generation is increasing rapidly, yet storing surplus electricity and reducing carbon dioxide emissions remain significant challenges. Existing energy systems require efficient solutions that connect renewable power generation with long-term energy storage.
CO₂ Emissions
Industrial carbon dioxide emissions remain an underutilized resource.
Surplus Renewable Energy
Renewable electricity cannot always be consumed when generated.
Energy Storage
Efficient long-term storage solutions are essential for a stable energy supply.
Industrial Integration
Sustainable technologies must integrate seamlessly into existing infrastructure.
The solution: a biological process instead of high-temperature technology
Natural microorganisms (archaea) live on a purpose-built carrier material and combine waste CO₂ with hydrogen from surplus electricity into grid-injectable methane — thermophilic at 55 °C, pressureless, without high-temperature peripherals.
The product replaces fossil natural gas and can be used in the existing gas grid — storable for months.
Mild process at around 55 °C
instead of 300–550 °C — no expensive special components
Load-flexible between 10 and 110 %
follows volatile electricity prices in real time
Tolerant of typical trace substances
from biogas and sewage gas — suitable for real existing plants
Standardized container design
series-manufacturable, deployable decentrally
How Biological Methanation Works
In four steps from industrial CO₂ residual stream to grid-injectable e-methane — standardized, biological, and modular.
Capture CO₂ from your plant
Capture of biogenic CO₂ from sewage gas facilities, biogas plants, or industrial point sources.
Generate green hydrogen from renewable electricity
Electrolytic production of H₂ powered by wind, solar, or surplus renewable electricity.
Biological methanation in CarboFerm® reactor at 55 °C
Thermophilic biological conversion of CO₂ and H₂ by specialized methanogenic microorganisms inside a 20-ft container.
Drying, conditioning and gas grid injection
Quality conditioning of e-methane for direct injection into existing natural gas grids or CNG/LNG utilization.
For Your CO₂ Source
Methanica's modular technology connects flexibly to various biogenic and industrial CO₂ streams — without replacing existing infrastructure.

Sewage Gas Plants
CO₂ from digester gas processing at municipal wastewater treatment plants — a concentrated residual stream that has gone unused until now.

Biogas Plants
Rule of thumb: a 500 kW biogas plant delivers around 120–150 Nm³/h of raw-gas CO₂ — ready to feed directly into an MSU cascade.
