Aemetis Biogas signs $27-MM agreement with Centuri to build gas cleanup systems for 15 dairy digesters
Aemetis, Inc., a renewable natural gas and renewable fuels company focused on low and negative carbon intensity renewable fuels, announced that its Aemetis Biogas subsidiary has signed a $27-MM equipment agreement with Centuri Holdings, Inc., a $2.6-B infrastructure services contractor, to build biogas cleanup systems for 15 dairy digesters.
This signed agreement, and expected future agreements with Centuri, will enable Aemetis Biogas to rapidly scale up the construction of dairy digesters to produce renewable natural gas (RNG) for a total of 50 dairies that have already been signed by Aemetis Biogas. This summer, 16 dairies are scheduled to be operating in the Aemetis Biogas Central Digester Project near Modesto, California, with 36 miles of biogas pipeline and a central biogas-to-RNG production facility already in operation delivering RNG into the PG&E utility gas pipeline.
“Our expanding strategic relationship with the experienced team at Centuri ranges from this agreement for biogas equipment to plans for construction management and pipe assembly to build upcoming energy efficiency, carbon sequestration and other projects,” stated Eric McAfee, Chairman and CEO of Aemetis. “We expect that Centuri will play a key role in building Aemetis projects on time and on budget, given their expertise in constructing industrial facilities, large scale gas pipeline projects. and utility electrical systems.”
“Centuri’s vast utility distribution expertise includes a growing number of renewable natural gas projects in multiple geographies, making the work with Aemetis a natural fit,” stated Dylan Hradek, President of US Gas at Centuri. “We expect to add significant value to upcoming projects at the Riverbank site and to support their ongoing work and plans to deliver innovative, renewable energy solutions across their portfolio.”
Aemetis renewable energy and energy efficiency projects include the expansion of dairy renewable natural gas production to generate more than 1 MMBtu of renewable natural gas from 50 dairies that have signed agreements; the Keyes ethanol plant mechanical vapor recompression system that is expected to generate $32 MM of increased annual cash flow starting in 2026; the Riverbank carbon sequestration project to inject 1.4 MMtpy of CO2 underground; the 78 MMgpy sustainable aviation fuel and renewable diesel plant which has already received the Authority To Construct air permits and the other key approvals; and negotiations underway for other large scale industrial and electrical projects at the Riverbank site.
