What Green2x does
Green2x (legal entity Green2x a/s, headquartered in Hellerup, Denmark) is a pre-revenue industrial biotechnology company developing large-scale facilities that convert biomass waste, primarily agricultural straw, into bioenergy. Its core technology is a patented, optimized biogas process in which straw is compressed into high-density briquettes and processed through an advanced fermentation step to produce biogas, which is upgraded to biomethane and can be further processed into advanced biofuels such as bio-methanol. The company claims the process lowers CO2 emissions by approximately 85% compared to conventional gas and uses a single, widely available feedstock with only fertilizer-grade residue as byproduct.
Green2x sells its output on a B2B basis to industrial manufacturers, heavy goods transport and maritime shipping operators, and energy utilities through long-term offtake agreements, with its first such agreement signed in September 2024. The go-to-market motion is enterprise field sales with custom contract negotiations tied to volume commitments. Distribution is direct to enterprise counterparties with no third-party channel partners identified.
The company is currently in project-development stage. Its flagship 100,000+ square meter facility at Vordingborg Port, Denmark (3x the output of the current largest plant in the world) is targeted to begin processing straw into green energy in late 2028, with a pilot plant under construction in 2025. A second site reservation exists with Copenhagen Malmö Port (2024), and the company has publicly stated intent to expand globally before 2030. Founded as Vordingborg BioFuel in 2020 and renamed in 2022, Green2x is led by CEO Mikkel Sjølin Kiil and has raised an undisclosed angel round (2020), an undisclosed largest round (2022), and $15.5M in November 2025 from Export and Investment Fund and Equinor.

Revenue model
- Biogas/Biomethane Sales: Green2x produces biogas through its proprietary process, upgrades it to biomethane, and sells the output to industrial customers and energy providers. Revenue is generated through long-term offtake agreements with enterprise buyers in manufacturing, transport, and energy sectors. The Vordingborg facility will produce biogas for sale to replace natural gas and fossil fuels.

Green2x product offering
Product offeringCore offering
Green2x converts biomass waste (primarily straw) into bioenergy through a patented advanced fermentation process, producing biogas that is upgraded to biomethane and further to bio-methanol. The company develops, constructs, and operates large-scale processing facilities (with the flagship Vordingborg site spanning 100,000+ square meters) to deliver these renewable fuels to industrial manufacturers, transport operators, and energy utilities as replacements for natural gas and fossil fuels.
Product overview
Green2x operates a single unified technology platform that transforms biomass waste into bioenergy. Their core process converts straw and other biomass through a patented advanced fermentation system into biogas, which is then upgraded to biomethane, and can be further processed into bio-methanol. The company develops, constructs, and operates large-scale processing facilities to deliver these energy products, positioning their technology as a scalable solution for the green transition across road transport, marine fuel, industrial production, and electricity/heat sectors.

Green2x competitors and assessment
Company assessmentDirect peers
- EnviTec Biogas: German-based biogas plant builder and operator with hundreds of agricultural and waste-to-biogas installations across Europe. Closely comparable to Green2x in the technology stack (anaerobic digestion of agricultural residues into biomethane) and in targeting industrial and gas-grid offtake.
- European Energy: Danish renewable energy developer with a sizable biogas and Power-to-X portfolio, building large biomethane and e-methanol facilities in Denmark and abroad. Comparable to Green2x as a Danish-headquartered developer of large-scale biomethane and renewable fuel projects for industrial offtake.
- Nature Energy: Denmark's largest biomethane producer, operating large-scale agricultural-waste-to-biogas plants across Denmark and internationally. Direct overlap with Green2x on feedstock category (organic waste), geography (Denmark) and product (upgraded biomethane injected into the gas grid).
- Bigadan: Danish biomethane producer with multiple large biogas plants processing manure and organic industrial waste into upgraded gas. Overlaps with Green2x on Danish geography, agricultural-waste feedstock, and biomethane sold to utilities and industrial users.
Emerging players
- Sunfire: German electrofuel and bio-methanol developer using Power-to-X and biomass-to-methanol pathways to produce renewable fuels for shipping, chemicals, and road transport. Comparable to Green2x on the bio-methanol product angle and the same renewable-fuel end-markets (maritime, industry).
Broad incumbents
- Ørsted: Danish-headquartered global renewables major with a stated ambition in renewable gases (green hydrogen and biomethane) for hard-to-abate sectors. Comparable to Green2x as a Danish incumbent entering the same biomethane/renewable-gas market for industrial offtake.
- Neste: World-leading producer of renewable diesel and sustainable aviation fuel from waste and residue feedstocks, with growing biomethane and renewable-chemicals exposure. Comparable to Green2x as a scaled renewable-fuels producer competing for the same industrial and transport offtake customers.
- Shell (biogas/biomethane segment): Global energy major that acquired Nature Energy in 2024 and is scaling biomethane and renewable-fuels capacity worldwide. Comparable to Green2x as a buyer and builder of biomethane volumes and as a competitor for long-term industrial offtake contracts in Europe.
- Equinor: Norwegian energy major that is both an existing Green2x equity investor and an active player in biomethane, biofuels, and renewable hydrogen in Northern Europe. Relevant as a strategic/financial peer shaping the same industrial renewable-fuels supply chain Green2x targets.
Regional players
- BioEnergy AT: Austrian developer of medium- and large-scale agricultural-biogas and biomethane plants across Central Europe. Comparable to Green2x in feedstock (agricultural residues), technology (anaerobic digestion/upgrading), and end-customers (industrial gas users and utilities), though focused on DACH rather than the Nordics.
