Aemetis Achieves Major Engineering Milestone, Begins Procurement for Riverbank Cellulosic Ethanol Plant

CUPERTINO, CA – March 12, 2018 – Aemetis, Inc. (NASDAQ: AMTX) announced today that it has achieved a major engineering milestone with its engineering firm, ATSI, by completing front end loading (FEL) engineering for its 12 million gallon per year cellulosic ethanol plant in Riverbank, CA.  In early 2017, Aemetis and ATSI began the design of the integrated gas fermentation facility at the Riverbank plant, which combines LanzaTech’s gas fermentation technology with InEnTec’s arc furnace gasification technology.  After nine months of engineering, optimization and demonstration plant testing, Aemetis has now completed all engineering necessary to begin the procurement of long lead-time equipment for the Riverbank facility.  Aemetis is currently engaging with vendors and contractors to coordinate the construction of the initial 12 million gallons of cellulosic ethanol in California, in addition to each subsequent phased build out.

“Aemetis is very pleased to be working with ATSI’s world-class team to bring our Riverbank cellulosic ethanol plant to full commercial implementation,” said Eric McAfee, Chairman and CEO of Aemetis, Inc.  “We are equally excited to begin commercial discussions with key vendors and potential partners in the industry who will help us begin the procurement and construction phase for this and future projects.”

After an extensive vetting of leading engineering and EPC firms, Aemetis selected ATSI for their deep expertise and experience in both gasification design and the integration of back end process technologies.  The ATSI Sustainability team has been designing and executing capital projects for over 40 years,  and has a wealth of experience in renewable and traditional power, industrial, chemicals,  refining, metallurgical, gasification and biofuel facilities.  With extensive experience including evaluating the design of gasification projects in the industry, ATSI began engineering the Aemetis project by evaluating and confirming the selection of InEnTec as the best gasification option available for the Aemetis project due to the low contaminant loading, high yielding carbon monoxide and hydrogen ratios, and scalable solution.

“ATSI has vetted, designed, and executed projects with many similar processes over the past decade and believes this project offers strong potential economics and technologic readiness,” said Josh Dickenson, Director of Business Development at ATSI. “We believe this project has a positive future of technology deployment in California and around the globe.  ATSI’s goal is to be the partner and springboard that allows Aemetis realize their advanced biofuels mission through the development of its 12 MGY facility in Riverbank in addition to the additional planned deployment sites,” added Dickenson.
