Sustainable Aviation Fuel and Renewable Diesel

We create renewable fuels from wood waste and other biomass.

Aemetis’s sustainable aviation fuel (SAF) and renewable diesel will be created from biomass generated from scrap agricultural products like orchards and vineyards, combined with renewable vegetable oil and animal fats. There are more than a million acres of almond orchards in California. Almond trees are removed and new trees are planted every 15-25 years. Farmers typically burn more than two million tons per year of agricultural waste, resulting in high emissions and poor air quality for surrounding communities. New laws limit the ability for farmers to burn agricultural waste in California.

Through a process called gasification, the Aemetis facility will distill the wood fibers to create hydrogen. This hydrogen is then combined with vegetable oil and animal fat to produce sustainable aviation fuel and renewable diesel. The Aemetis facility is designed with flexibility in mind, with the ability to adjust the outputs to produce either renewable diesel only or a mix of renewable diesel and up to 50% SAF, allowing Aemetis to respond to changing market conditions for the two products.

Aemetis is purchasing a 125-acre, commercial/industrial site at a former ammunition facility in the Central Valley town of Riverbank that will be the site of the SAF/renewable diesel plant. It will be co-located with a Carbon Capture and Storage facility, allowing Aemetis to reduce atmospheric carbon levels as part of its SAF/renewable diesel production.

Why SAF and Renewable Diesel?

The U.S. consumes more than 40 billion gallons of diesel on U.S. roadways every year and more than 10 billion gallons of aviation fuel. Petroleum in transportation creates 1,700 Million metric tons of CO2 per year. Diesel and aviation fuel also emit soot, carbon monoxide, nitrogen oxides (NOx), and other hazardous air pollutants.

Renewable diesel meets the same standards and quality controls that traditional petroleum diesel meets. Renewable diesel performs comparably to traditional diesel but contains dramatically lower tailpipe and lifecycle emissions.

Additionally, our facilities will produce SAF and renewable diesel at or below the carbon intensity of comparable fuels in the market today. When combined with carbon capture and storage, our facilities permanently remove atmospheric carbon dioxide, lowering overall greenhouse gases. Transportation relies heavily on petroleum, and finding nature-based alternatives is one of the most powerful ways to stop greenhouse gas emissions.

We create renewable fuels from sustainable vegetable oil and animal fat.

Aemetis’s biodiesel is created from biomass generated from sustainable vegetable oil and animal fat. It is created through a transesterification process, generating a renewable, biodegradable fuel that can be used in many of the same ways as traditional petroleum diesel, including use as a transportation fuel, as heating oil, and as a textile lubricant.

Aemetis owns and operates a 50-million gallon per year integrated fuels and chemical production facility in Kakinada, India, which generates biodiesel, glycerin (a component in the chemicals industry), and edible oils. It is the largest biodiesel manufacturing plant in India. The biodiesel technology was supplied by ‘DeSmet-Ballestra’ from Italy, known for best-in-class available technology. In October 2008, Aemetis was amongst the first plants to commence biodiesel production in India.

Why Biodiesel?

India consumes more than 23 billion gallons of diesel annually. Diesel emissions include soot, carbon dioxide, carbon monoxide, nitrogen oxides (NOx), sulfur oxides (SOx), and other hazardous air pollutants. Biodiesel burns cleaner, improving overall air quality. Additionally, emissions standards in many countries call for decreased sulfur in petroleum diesel, which decreases the ability of the fuel to lubricate diesel engines. Mixing even a small percentage of biodiesel with traditional diesel restores the lubricity of the fuel, which supports the these emissions standards.
