Biomethane Production & CO2

Biomethane is a clean, renewable alternative to fossil natural gas. By upgrading raw biogas, we produce grid-quality biomethane suitable for gas-to-grid injection, as well as for the production of BioCNG and BioLNG used in industrial and transport applications. Bright Renewables’ PurePac biogas upgrading systems use proven membrane technology to deliver high-efficiency purification.

Adding a CO2 liquefaction system to your biogas upgrader achieves 100% methane recovery and creates new revenue streams. Bright’s CO2 technology recovers CO2 from biogas upgrading or carbon capture processes and produces food-grade liquid bioCO2. Liquid bioCO2 has a wide range of applications. It is used in beverage carbonation and food preservation, enriches greenhouse atmospheres to boost plant growth, and serves as an eco-friendly refrigerant. It also plays a role in water treatment for pH control and is a key component in fire suppression systems.

These modular solutions can be combined to maximise efficiency, sustainability, and profitability for your biogas project.

What makes Bright’s biogas upgrading technology unique?: Bright’s systems feature a three-stage membrane separation process that ensures high methane yield and minimal methane slip/loss (<0.5%). The modular, containerised design reduces installation time and footprint, while fully automated operation and remote monitoring simplify management. Optional heat recovery systems further improve efficiency by converting compressor energy into usable heat, reducing operational costs.
What is CO2 recovery and why is it important in biomethane production?: CO2 recovery captures carbon dioxide separated during biogas upgrading and converts it into liquid CO2 through a cooling and compression process. This food-grade CO2 can be used in the beverage industry, refrigeration, or greenhouse enrichment to promote plant growth. CO2 recovery and liquefaction creates an additional revenue stream and supports circular economy principles by turning a waste product into a valuable resource.
Are Bright’s systems easy to install and operate?: Yes. Bright’s solutions are delivered as containerised, pre-tested units, minimising on-site installation time. The systems are fully automated, with advanced controls that respond quickly to biogas fluctuations. Remote monitoring and 24/7 support ensure optimal performance and reliability.
Can these systems be scaled for different applications?: Absolutely. Bright’s modular design allows systems to be tailored for small-scale agricultural projects or large industrial facilities. Options such as BioLNG production, CO2 liquefaction, heat recovery, and CNG compression can be added based on specific project requirements.
