Green Gas Solutions

Who we are

Green Gas Solutions (GGS) is a Danish specialist in renewable-gas hardware and turnkey solutions. We position ourselves as a one-stop partner for the biogas and green gas value chain—covering upstream upgrading, purification, liquefaction and grid-transport & injection.
With more than 15 years of industry know-how, GGS works with leading international equipment suppliers and focuses on the Nordic market while supporting export opportunities as well.

What we do

Our core capabilities span:

• Biogas upgrading – transforming raw biogas into high-quality biomethane suitable for grid injection or transport applications.

• H₂S removal / desulphurization – advanced systems (e.g., biological processes) for reducing hydrogen sulfide in high-load biogas and CO₂ streams.

• CO₂ and biomethane liquefaction / LBG – hardware for turning CO₂ (from biogas or other sources) and biomethane into liquid form for storage, transport or industrial use.

• Grid injection & refuelling solutions – compressors and gas-stations (CNG/biomethane) plus grid compression/injection modules, including compressor solutions for H₂ and CO₂.

• Air & odour treatment, filtration – specialist filtration of biogas, gas streams and large volume of air, to ensure reliability, longevity and compliance.

• Service & maintenance – support, lifecycle service, maintenance contracts via local partners to ensure uptime and operational reliability.

Why we matter

• We bring together best-in-class technology suppliers under one roof, so that our clients don’t need to piece together multiple fragmented vendors.

• Our local Nordic market strength means we understand the regional regulatory, operational and feedstock contexts (e.g., high moisture, varying biomasses, grid injection requirements).

• Because we handle the “hardware & technology enabling” side—from upgrading to liquefaction to injection—our solutions support the full chain from raw biogas → green gas → grid/transport form.

• For partners, developers or investors in biogas / CCUS / sector-coupling projects, GGS offers a reliable technical platform and commercial anchor in the Nordic region.

What we offer to clients & partners

• A transparent hardware-focused offering: you get systems (not just components) that are proven, modular, and tailored to biogas/green gas projects.

• Expertise in matching hardware to project conditions: feedstock, gas composition, local grid/transport requirements.

• A partner able to coordinate with EPCs, utility clients, and technology vendors, simplifying project interfaces.

• A Nordic reference list—meaning experience and established operational service arrangements.

• Flexibility: suitable for greenfield plants, retrofit/upgrades, grid injection, transport solutions.
