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

Aemetis, Inc., a leader in renewable natural gas and fuels, has announced a major expansion of its biogas production capabilities with the completion of initial construction on a multi-dairy anaerobic digester in Merced County, California. The new facility, expected to begin operations by the end of 2024, will process waste from approximately 14,000 dairy cows and produce over 200,000 MMBtu of renewable natural gas (RNG) per year.

This development represents a significant step forward in Aemetis' efforts to reduce greenhouse gas emissions and provide sustainable energy solutions. The multi-dairy digester is designed to collect waste from four dairies located within a half-mile radius and is connected to the company's existing 36-mile biogas pipeline. This strategic placement maximizes efficiency and reduces transportation costs associated with waste collection.

The expansion of Aemetis' biogas production capacity comes at a crucial time when the demand for renewable energy sources is rapidly increasing. The company's focus on converting dairy waste into RNG not only addresses the environmental concerns associated with agricultural waste management but also contributes to the reduction of methane emissions, a potent greenhouse gas.

Currently, Aemetis generates biogas from ten dairy-based anaerobic digesters, producing approximately 300,000 MMBtu of RNG annually. With the addition of the new multi-dairy digester and two other facilities, the company's production capacity is set to increase to around 550,000 MMBtu per year, sourced from a total of 16 dairies. This substantial increase in production underscores the scalability and potential of dairy-based biogas as a renewable energy source.

The economic implications of this expansion are significant. Aemetis is poised to benefit from credits under the Low Carbon Fuel Standard and Production Tax Credits from the Inflation Reduction Act, starting in January 2025. These incentives are expected to support further construction of digesters for additional dairies, potentially leading to job creation and economic growth in the renewable energy sector.

Looking ahead, Aemetis has ambitious plans for further expansion. The company has signed agreements with 48 dairies and aims to add another 27 to its biogas portfolio. When fully operational, the Aemetis Biogas Central Dairy Project is projected to generate more than 1.6 million MMBtu of RNG annually, with expected revenues of $250 million per year. This level of production would represent a substantial contribution to the renewable energy market and a significant reduction in greenhouse gas emissions from dairy operations.

The implications of Aemetis' expansion extend beyond the company itself. As the world grapples with the challenges of climate change and the need for sustainable energy sources, projects like this multi-dairy digester demonstrate viable solutions for reducing carbon emissions while creating value from agricultural waste. The success of this project could serve as a model for similar initiatives across the United States and globally, potentially transforming the dairy industry's approach to waste management and energy production.

Moreover, the increased production of RNG could have far-reaching effects on the energy market, providing a reliable source of renewable fuel for various applications, including transportation and industrial processes. As governments and industries worldwide seek to reduce their carbon footprints, the availability of RNG at scale could accelerate the transition away from fossil fuels in multiple sectors.

In conclusion, Aemetis' completion of the initial construction phase of its multi-dairy digester marks a significant milestone in the company's growth and in the broader renewable energy landscape. As the facility moves towards full operation, it will be closely watched by industry observers, environmental advocates, and policymakers as a potential blueprint for sustainable waste management and renewable energy production in the agricultural sector.
