In this project Bright Biomethane realised a biogas upgrading system for upgrading biogas to biomethane in Jelsum, the Netherlands. The plant was originally constructed for generating electricity out of manure and co-products. Bright Biomethane completely repowered the installation with the latest available technologies for biogas upgrading. The original CHP has been replaced by the Bright Biomethane biogas upgrading unit. 180 Nm³/hr biomethane is produced out of 7,000 tons of manure and 7,000 tons of waste products. In early 2017 the first biomethane has been injected into the grid. More than 1 million Nm³ biomethane annually will be produced, which is equivalent to the natural gas consumption of 750 households.
