Green Energy for Industry and Transport
Certified biomethane supply, energy trading and infrastructure enabling companies across Europe to transition to low-carbon energy systems.
Industrial Biomethane
Industrial biomethane enables companies to replace fossil natural gas with renewable gas without changing existing gas-consuming infrastructure.
Through the European gas grid and certified mass balance systems, biomethane can be used directly in industrial boilers, CHP systems, and production processes as a drop-in energy source.
By switching to biomethane, companies can significantly reduce greenhouse gas emissions while improving carbon performance in ESG reporting, Environmental Product Declarations (EPD), and other sustainability documentation. Renewable gas consumption can also reduce exposure to rising EU ETS carbon costs.
Using guarantees of origin (GoO) and certified supply chains, biomethane consumption can be transparently documented, while the physical gas is delivered through the same grid as fossil natural gas.
ISCC and RedCert certification frameworks ensure traceability and reliable reporting, supporting industrial companies across Europe in their transition toward lower-carbon energy systems.
Green energy for road
Transport & Maritime
Biomethane is a renewable fuel capable of reducing direct greenhouse gas emissions by more than 100%.
Its drop-in compatibility with LNG engines allows flexible blending from 1% to 100%, enabling a gradual transition to low-carbon fuels without changing existing vehicles, vessels, or infrastructure.
Across Europe, new climate regulations such as the EU ETS for shipping are increasing the cost of fossil fuels and creating strong incentives for cleaner alternatives. Companies with a clear fuel strategy can turn these regulatory changes into a competitive advantage.
In that sense, renewable gas plays a key role in decarbonizing heavy transport on both land and sea. Bio-CNG for heavy-duty trucks and Bio-LNG for long-haul and maritime transport provide a reliable, low-carbon alternative to diesel and conventional marine fuels.
Through ISCC-certified biomethane, guarantees of origin, and transparent supply chains, renewable gas consumption can be documented and integrated into ESG and sustainability reporting.
Let us help you solve your green transport challenges - from strategy and emissions calculations to operational solutions such as your own depot filling station. We help logistics companies, fleet operators, and shipping companies reduce emissions while maintaining reliable operations.
Combined
Heat & Power (CHP)
Certified biomethane supply for CHP plants across Europe. Produce renewable electricity and district heating through the existing gas grid.
Replace fossil natural gas with certified biomethane in CHP plants without changing existing infrastructure. Through the European gas grid and mass balance systems, Fremsyn supplies renewable biomethane to CHP installations across Europe.
This enables energy companies, municipalities and housing cooperatives to produce renewable electricity and district heating while significantly reducing the carbon intensity of their energy systems.
Fremsyn structures long-term biomethane supply agreements with guarantees of origin, providing reliable renewable fuel together with transparent sustainability documentation for ESG, EPD and carbon reporting.
While our strongest market positions are in Sweden and Switzerland, biomethane supply can be structured for CHP operators across the European energy market.
Gas Trading &
Guarantees of Origin
Access our green energy trading desk for physical biomethane, Guarantees of Origin (GoO), biogenic CO₂ and e-methane across European energy markets.
Through our trading company Biogem, we trade renewable gas from our own production facilities as well as from partner biogas plants, providing market access, certification management and structured sales channels for producers.
Supply can be arranged through day-to-day market transactions or long-term agreements of up to ten years, including bundled deliveries of biomethane and guarantees of origin, providing reliable proof of renewable gas consumption and supporting ESG and carbon reporting requirements.
This flexibility allows industrial energy consumers and utilities to balance operational needs with long-term decarbonization strategies.
All transactions are structured and verified through ISCC and RedCert-certified frameworks, ensuring transparent mass balance accounting and reliable sustainability documentation for industrial energy consumers and utilities.
