BIOGAS UPGRADING TO BIOMETHANE

Bright Renewables offers a well-proven system to upgrade biogas to a methane-rich product gas, also known as biomethane. By applying highly efficient membranes the separation of methane from biogas can reach an efficiency of more than 99.5% and render biomethane suitable for injection in the national grid or compression to CNG. Read more about our technology.

Multiple applications

The methane-rich product gas can be used for different purposes. One of the options is to inject the obtained gas into the natural gas grid. Another option is to use the gas as transport fuel (bio-CNG) for vehicles. Our virtual pipeline technology is the solution for biomethane production when no gas grid infrastructure is in place at the production location. Biomethane is a CO₂neutral, clean fuel without particles, that provides a good alternative to fossil fuel. The CO₂that is removed from the biogas can be recovered and liquefied to create an extra source of revenue for the plant owner.

Why choose for biogas upgrading by Bright Renewables?

Reliable
Proven membrane technology achieving more than 97% operational availability. The biomethane plant is easily integrated with a biogas plant, provides optimal gas cleaning, a robust design, an advanced patented control system and the assurance of 24/7 service support.
Experience
Having constructed the world’s first commercial plant for upgrading biogas using a 3-stage membrane system, Bright Renewables successfully uses this proven design in its systems operating today.
Quick to grid
The advanced design and patented control system makes it possible to inject specification compliant biomethane to grid within a few minutes of start-up. Other technologies can take much longer to start-up with resultant methane losses and operational inconvenience. Bright Renewables plant operators have the option to stop and start the facility at their convenience with minimal methane loss and no wasted energy consumption.
Profitability
99.5% methane recovery, more than any other system. The lowest electricity consumption (0,22 kWh/Nm³biogas). No heat required for the biogas upgrading process. Heat recovery (> 0,25 kWt/Nm³ biogas) covering the main energy consumption of the biogas facility. Competitive price level.
CO2 Recovery
A Bright Renewables CO₂recovery unit can also be integrated with the standard 3 or 2 stage membrane upgrading systems. The high separation efficiency of the membranes means that the energy consumption of CO₂ liquification is much lower than conventional systems.
No chemicals, no waste(water)
No water or chemicals are needed in the Bright Renewables process which means that there are no disposal problems, such as acid water or chemicals that can be an unforeseen cost with other technologies.
Gas treatment
Bright Renewables is experienced in managing biogas produced from most forms of biomass feedstock, including municipal sludges and wastes. Based on this experience, reliable biogas pre-treatment solutions can be offered to ensure the correct biogas specification is achieved before upgrading.
