Leading the way in Biogas-to-RNG engineering services

ESI is an industry leader in Renewable Natural Gas (RNG) facility engineering, design, and technical consulting. With Federal and State incentives driving an ever-increasing demand for RNG within the United States, ESI has carried the flag in supporting developers with the technical skills and experience needed to execute these demanding projects. As a single source provider, ESI provides a full suite of technical services for RNG projects including: process, mechanical, electrical, and controls engineering services. ESI’s technical proficiency in gas separation of biofuels includes experience, integration, and understanding with a wide variety of technologies including: membrane, PSA, TSA, amine, water wash, biological scavengers, bulk media removal, and more. As a true third party engineer, ESI is technology agnostic but maintains relationships with most of the major RNG technology suppliers in the industry. ESI helps RNG investors develop biogas resources such as landfill gas, animal waste, agricultural waste, recycled organics, and other anaerobic digester sources. ESI is committed to providing clients with the best RNG solution for each project’s unique needs.
