Aemetis Biogas successfully completes testing of dairy biogas-to-RNG upgrading and compression facility

In California, Aemetis Biogas achieved a significant milestone by successfully completing testing of the $12 million dairy biogas-to-RNG upgrading and compression facility for the Aemetis Biogas Dairy Digester Project in California. The biogas upgrading unit is co-located at the Aemetis Advanced Fuels Keyes ethanol plant near Modesto, California and adjacent to the utility natural gas pipeline. 

The full system mechanical commissioning process for the biogas-to-RNG facility has been completed.  Pacific Gas & Electric (PG&E) is now conducting final tests of the utility gas pipeline interconnection unit that is already constructed, which will enable the injection of utility-grade renewable natural gas into the PG&E gas pipeline for delivery to customers.  

Site development, engineering, permitting, construction and successful operational testing of the Aemetis biogas upgrading facility and the PG&E interconnection unit was achieved over a three-year period within the original project budget.

When fully built out, the planned 60+ dairies in the estimated $380 million Aemetis biogas project are expected to capture more than 1.6 million MMBtu of dairy methane and reduce greenhouse gas emissions equivalent to an estimated 5 million metric tons of CO2each year, equal to removing the CO2 emissions from more than 1 million cars per year.
