Unlock the Full Value of Your Biogas
Gas Upgrading
& CO₂ Capture Systems
Biogas contains valuable renewable energy, but its full potential can only be realized through effective gas upgrading and purification. At Grants Biotech Ltd, we provide advanced gas upgrading and CO₂ capture solutions that convert raw biogas into high-quality biomethane while recovering biogenic carbon dioxide for commercial and industrial applications. Working with leading technology partners, we supply and support both membrane-based and PolyCapture™ gas upgrading systems, helping clients maximize the value of their anaerobic digestion projects while reducing environmental impact.
Our Advanced Gas
Upgrading Technologies
We source and install two primary types of gas upgrading systems, allowing us to deploy the ideal technology based on your project scale, purity targets, and budget:
PolyCapture™ Gas Upgrading Systems
A highly specialized, robust purification system optimized for agro-industrial settings. PolyCapture™ technology offers exceptional reliability, low chemical overhead, and high-efficiency separation to yield premium gas outputs even under varying raw gas compositions.
Membrane Separation Systems
Utilizing state-of-the-art, high-permeability polymeric membranes, this system dries, compresses, and filters biogas. Methane molecules are cleanly separated from CO_2 via pressure differentials, offering a highly automated, compact, and easily scalable footprint.
Commercial Applications for
Upgraded Outputs
By upgrading your biogas with GBL systems, your facility generates two distinct revenue or cost-saving streams:
1. High-Quality Biomethane
Can be compressed (CNG) for use as a clean vehicle fuel for logistics fleets, used as a direct pipeline substitute for natural gas, or burned in high-efficiency CHP engines for reliable corporate power.
2. Biogenic CO2 Capture
Reclaim carbon dioxide that would otherwise be vented. This green, non-fossil CO_2 can be purified for use in commercial greenhouses to accelerate plant growth, or utilized in industrial processing, drastically improving your facility's carbon accounting.
