Bio Energy solutions
Let Fremsyn help you align your ambitions
for the green transition.
Industrial Biomethane
Industrial biomethane allows companies to replace fossil natural gas with renewable gas without changing existing infrastructure. As a drop-in fuel, biomethane can be used directly in industrial processes, boilers and CHP systems, providing a practical way to reduce greenhouse gas emissions.
By switching to biomethane, companies can reduce reliance on EU ETS allowances while improving carbon performance reporting, Environmental Product Declarations (EPD) and other sustainability documentation.
Through guarantees of origin and certified supply chains, our renewable gas from own or corporation biomethane plans, consumption can be transparently documented.
Standards such as ISCC and RedCert ensure traceability and reliable reporting, helping industries across Europe transition toward lower-carbon energy systems.
Biogas for Transport & Maritime
Renewable gas plays an important role in decarbonizing heavy transport. Sustainable bio-CNG for heavy-duty trucks with own depot fulling station and access to European bio-LNG terminals, we provide a low-carbon alternative to diesel and conventional marine fuels while maintaining reliable vehicle and vessel performance.
Biomethane is compatible with existing gas infrastructure and engine technologies, bio-CNG and bio-LNG allow fleets and shipping companies to reduce emissions without major operational changes. Certified ISCC-biomethane can significantly lower greenhouse gas emissions across transport operations.
Through guarantees of origin and certified supply chains across Europe and the United States, renewable gas consumption can be transparently documented.
This enables logistics companies and maritime operators to reduce emissions, strengthen ESG reporting and accelerate the transition to low-carbon transport.
Combined Heat & Power (CHP)
Biomethane-based combined heat and power (CHP) systems convert renewable gas into both electricity and useful heat in a single, highly efficient process.
Widely used in Sweden and Switzerland, CHP installations support local energy systems by supplying renewable power alongside district heating for communities and industry.
By utilizing biomethane as a fuel, CHP plants deliver stable energy production while significantly lowering the carbon intensity compared with conventional fossil-based generation.
Technology enables reliable cogeneration that supports industrial operations, district heating networks and local energy resilience.
With certified biomethane supply and transparent sustainability documentation, CHP solutions help utilities and energy producers expand renewable electricity generation while contributing to lower-emission heating and power systems.
Gas Trading & Guarantees of Origin
Professional green gas trading solutions provide access to OTC biomethane contracts and European guarantees of origin for gas, enabling companies to secure certified renewable gas for their energy supply.
Trading can be structured both as short-term deliveries and day-to-day market transactions, as well as long-term supply agreements extending up to ten years.
This flexibility allows industrial energy consumers and utilities to balance operational needs with long-term decarbonization strategies.
ISCC-compliant trading structures ensure transparent mass balance accounting and verified sustainability documentation, providing reliable proof of renewable gas consumption and supporting ESG and carbon reporting requirements.
Battery Energy Storage Systems
Battery energy storage systems provide flexible energy management and improved grid stability for industrial and commercial energy users but also EV-supercharging on small and unstable grids.
By storing electricity when supply is high and releasing it when demand increases, our solutions help balance fluctuating renewable energy production and optimize energy consumption.
Get CAPEX-free EV-charging infrastructure for fleets and heavy-duty transport with battery buffer technology and scalable BESS installations up to 4.5 MWh support a wide range of applications, including peak shaving, backup power and participation in grid services.
These systems enhance energy resilience while enabling businesses to manage energy costs and integrate larger shares of renewable electricity into their operations
