Aemetis Biogas Expands Renewable Natural Gas Production with Multi-Dairy Digester

Aemetis, Inc., a leading renewable fuels company, has announced the completion of initial construction on a multi-dairy anaerobic digester in Merced County, California. The facility, designed to process waste from approximately 14,000 dairy cows, is expected to commence operations by the end of 2024 and produce over 200,000 MMBtu of renewable natural gas (RNG) annually.

This development represents a significant expansion of Aemetis' biogas production capabilities. The new multi-dairy digester, along with two other digesters scheduled to come online, will boost the company's RNG production from the current 300,000 MMBtu per year to approximately 550,000 MMBtu annually. The project is part of Aemetis' broader Central Dairy Project, which aims to eventually generate more than 1.6 million MMBtu of RNG per year from 48 dairies, potentially yielding annual revenues of $250 million.

The strategic importance of this expansion lies in its alignment with growing demand for renewable energy sources and the reduction of greenhouse gas emissions. The project leverages California's Low Carbon Fuel Standard and will benefit from Production Tax Credits under the Inflation Reduction Act starting in January 2025, showcasing the intersection of environmental initiatives and economic incentives in the renewable energy sector.

For the dairy industry, this project offers a solution for waste management while creating a valuable energy resource. The multi-dairy digester's proximity to four dairies, all within half a mile, demonstrates an efficient model for localized renewable energy production. Connected to Aemetis' 36-mile biogas pipeline, the project illustrates the potential for scaling up biogas infrastructure in agricultural regions.

The implications of this development extend beyond Aemetis and the dairy industry. It represents a growing trend in the renewable energy sector towards utilizing agricultural waste for energy production, potentially influencing future energy policies and investment strategies in the field of sustainable agriculture and renewable fuels. As the demand for low-carbon intensity products continues to rise, projects like this could become increasingly crucial in meeting renewable energy goals and reducing the carbon footprint of both the agricultural and energy sectors.
