Aemetis completes biogas-to-RNG testing
Aemetis Biogas has completed testing of its $12 million (€11 million) dairy biogas-to-RNG upgrading and compression facility in California.
The biogas upgrading unit is co-located at the Aemetis Advanced Fuels Keyes ethanol plant near Modesto and adjacent to the utility natural gas pipeline.
The full system mechanical commissioning process for the biogas-to-RNG facility has been completed. PG&E is now conducting final tests of the utility gas pipeline interconnection unit that has already been built, which will enable the injection of utility-grade RNG into the gas pipeline for delivery to customers.
“Completing the construction and successful testing of the biogas upgrading and compression facility is a significant milestone that will allow Aemetis to sell -426 carbon intensity RNG to fleet customers across California,” said Eric McAfee, chairman and CEO of Aemetis.
“In addition to our two operating dairy digesters and 16 miles of biogas pipeline, Aemetis continues to be on schedule to add five dairy digesters to our network this summer to meet increasing demand for lower cost, low emission, carbon-negative RNG to replace petroleum diesel in trucks, buses and other heavy transport vehicles.”
When fully built out, the planned 60+ dairies in the estimated $380 million (€349 million) Aemetis Biogas Dairy Digester 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 tonnes of CO2 annually.
Recently, Aemetis acquired an 8.5-acre property in California, close to the Keyes renewable ethanol plant, to develop its Carbon Zero projects. The corner property, acquired for $2 million (€1.8 million), is a strategic location for operations supporting the company’s Carbon Zero projects, including dairy RNG and CCS.
