Representatives of Aemetis Inc. discussed progress with the company’s biogas, ethanol, cellulosic biofuel and carbon capture and storage (CCS) initiatives during a third quarter earnings call, held Nov. 11.
Andy Foster, president of Aemetis Advanced Biofuels, highlighted progress being made by the company’s biogas subsidiary. He said Aemetis completed phase one of its dairy digester project in September, with operations commencing at the first two covered lagoon digesters, including onsite dairy biogas cleanup and pressurization. Phase one also included the development of a 4-mile pipeline and a boiler unit to utilize biogas as process energy at the company’s ethanol plant in Keyes, California. The use of biogas at the ethanol plant has allowed the facility to lower the carbon intensity (CI) score of the ethanol it produces.
Foster said Aemetis is now working on phase two of the dairy digester project, which includes a centralized biogas cleanup facility, a utility pipeline interconnection, and a renewable natural gas (RNG) fueling station located at the Keyes plant. Phase two also includes the addition of 15 more dairy digesters and 32 miles of pipeline. According to Foster, phase two development is on schedule for completion in the third quarter of 2022.
To date, Foster said Aemetis has signed agreements with 22 dairies to install digesters. In addition, the company is in advanced discussions with five more diaries, with agreements for those digesters expected to be signed before the end of the year. Aemetis is also engaged in discussions with more than a dozen additional dairies, according to Foster.
