Delivery of the RNG systems is part of a big revamp project from partner Martin Energy Group, which includes an overhaul on five existing digesters and replacing the CHP’s with Bright’s RNG technology.

This system will produce 216 SCFM of renewable natural gas (460 Nm3/hr of biomethane) from 350 SCFM biogas (567 Nm3/hr), but can be extended in the future to produce more biomethane.

The produced biomethane is both directly injected into the national grid and transported trough a virtual pipeline. This virtual pipeline technology allows to compress and transport gas in a mobile unit to a gas injection point (CNG/LNG fueling station) and to deliver it at the right pressure.

In addition to the production of biomethane, the system can also be extended with a Bright CO₂-liquefaction system to recover and liquefy the CO₂.
