PG&E Pipelines Transport RNG to California Transportation Sector

Project Captures More Than 1.6 MMBtu of Dairy Methane

Pacific Gas and Electric Company (PG&E) today joined with Aemetis, Inc. to officially commission the interconnection of a new Renewable Natural Gas (RNG) facility in Keyes, Calif. The partnership between PG&E and Aemetis will enable transportation of clean RNG to California transportation customers and capture more than 1.6 MMBtu of dairy methane per year that would otherwise be emitted into the atmosphere.

“We are proud to partner with Aemetis and California dairies to deliver clean renewable natural gas to Californians. This project is a key milestone in our goal to expand our renewable energy mix within our gas supply and evolve our system to be a safe, affordable, and reliable net zero energy delivery platform,” said PG&E’s Senior Vice President, Gas Engineering Janisse Quiñones.

At full build-out, a 40-mile gathering line will receive RNG produced at the Aemetis Biogas Central Dairy Digester Project and transport it through PG&E’s transmission pipeline system to end-use customers. Currently, the RNG transported from this project will directly support the transportation sector. The project estimates that emissions captured from more than 60 contributing dairies is equal to that of 1.1 million cars.

“Commissioning the biogas cleanup unit and interconnecting with PG&E’s gas pipeline is a significant milestone for Aemetis,” said Eric McAfee, Chairman and CEO of Aemetis. “Our ability to fuel trucks with negative carbon intensity RNG will contribute to California’s goal of carbon neutrality and will reduce transportation air pollution created by diesel emissions.”

The Aemetis Biogas Central Dairy Digester Project marks PG&E’s fourth RNG interconnection in the last six months. A fifth RNG project is slated to come online by Dec. 2022, advancing PG&E’s efforts to decarbonize the natural gas system and reduce emissions as outlined in the recently released Climate Strategy Report. The report details the company’s path to become net-zero on greenhouse gas emissions by 2040, and “climate positive,” or going beyond net zero emissions and actively removing more greenhouse gases from the environment than it emits, by 2050.
