SCS Energy: CALGREN Digester Gas Utilization to RNG Using Dairy Feedstock
The RNG plant is configured to allow renewable natural gas pipeline injection to SoCalGas. SCS Energy: CALGREN Digester Gas Utilization to RNG Using Dairy Feedstock CALGREN Digester Gas Utilization SCS designed a 2,500 scfm dairy digester gas to a renewable natural gas (DG-to- RNG) plant in Pixley, California. The product gas capacity is 2,100 MMBtu/day. SCS also provided assistance in equipment procurement, construction oversight and startup/testing. SCS provided the supervisory, control and data acquisition (SCADA) system on a turnkey basis. In the initial phase of this project, the RNG will be used to ?re a combustion turbine, because the combustion turbine requires pipeline quality gas. The feedstock for the digester is dairy manure. The facility came online in August 2018, with gas b
