Aemetis Inc., a renewable natural gas (RNG) and renewable fuels company focused on negative carbon-intensity products, announced that its subsidiary Aemetis Biogas is ready to launch phase 2 of biogas production by completing the construction of its 3rd dairy digester and successfully testing the 7-mile section of biogas pipeline to be used by the next 5 dairy digesters in Phase 2 of the Aemetis Biogas Central Dairy project.
Testing was recently completed for the $12 million dairy-to-RNG biogas upgrading and compression facility which is co-located at the Aemetis Advanced Fuels Keyes Ethanol Plant near Modesto, California, and at side of the natural gas pipeline. The PG&E Gas Pipeline Interconnect Unit has been built and is currently being tested by PG&E. Conversion of biogas to RNG and injection of RNG into the PG&E pipeline is planned for early May 2022, once PG&E completes testing.
“Completing the construction and filling of the first dairy digester in Phase 2 of the Aemetis Biogas Central Dairy project is a major milestone in our May RNG production schedule for delivery of gas into storage as we complete the CARB pathway approval process for generating LCFS credits. said Eric McAfee, President and CEO of Aemetis. “In addition to the three completed dairy digesters and over 16 miles of biogas pipeline we have built, Aemetis is under construction or final engineering to add the next 10 dairy digesters to our network to meet the growing demand for products. low-cost, low-emission, carbon-negative RNG to replace petroleum diesel in trucks, buses and other heavy-duty transport vehicles.
When fully constructed, the more than 60 dairies planned under 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 about 5 million metric tons of CO2 every year, which is equivalent to eliminating the CO2 emissions of more than one million cars per year.
