Aemetis Begins Deliveries of Carbon Dioxide under Supply Agreement with new Messer CO2 Plant

Ethanol Plant to Provide About 450 tons of CO2 Daily for use in Food, Beverage and Other Industries; Helps Meet Market Shortage Caused by COVID-19 Crisis

CUPERTINO, CA – May 1, 2020 – Aemetis, Inc. (NASDAQ: AMTX) announced today that it has commenced deliveries under a long-term agreement with Messer to supply carbon dioxide (CO2) to a newly-constructed, state-of-the-art CO2 plant located adjacent to the Aemetis ethanol plant.

This week, the Aemetis 65 million gallon per year ethanol plant began supplying CO2 to Messer for processing into liquid CO2 – a key product in the food freezing and chilling, carbonated beverage, and electronics sectors. Due to the ongoing COVID-19 pandemic, the supply of liquid CO2 has been significantly disrupted in California and throughout the United States as ethanol production plants have decreased production rates. The Messer plant will serve existing and new customers in Northern California and surrounding states via truck and rail.

For the past two years, Aemetis worked closely with Messer on the construction of a new CO2 facility which is connected via pipeline to the Aemetis ethanol production facility. Aemetis anticipates selling Messer approximately 450 tons of CO2 daily from the company’s ethanol fermentation process. Messer will then purify and convert the supplied CO2 into liquid form, which it sells to a variety of customers.

“Aemetis is pleased to be supplying Messer with CO2, especially in this time of critical need,” said Eric McAfee, Chairman and CEO of Aemetis. “It is essential that California’s supply of CO2 remain uninterrupted for the many industries that depend on this important product.”
