Built. Operated. Proven.
In a groundbreaking deployment, Velocys led the successful commissioning and operation of the first commercial gas-to-liquids plant (GTL) in the U.S. powered by landfill gas. The project validated Velocys’ advanced Fischer-Tropsch (FT) technology and set a new benchmark for renewable fuel production from waste-derived syngas.
Partners: Waste Management, NRG Energy, Velocys, and a regional EPC firm
Location: East Oak Landfill, Oklahoma City, OK
Feedstock: Landfill gas (LFG)
Envia set out to build and operate a first-of-a-kind (FOAK) gas-to-liquids plant that would:
Velocys’ microchannel FT reactor system was integrated into a modular GTL plant that included a steam methane reformer (SMR) to convert landfill gas into syngas. This was then upgraded into high-quality synthetic crude and separated into finished fuels.
Velocys assumed operational leadership during the critical commissioning phase—ensuring optimized performance, safety, and regulatory compliance.
Velocys became the only FT technology licensor to operate a commercial-scale GTL plant using renewable feedstock.
Landfill gas volumes and quality can shift unpredictably—systems must be robust and flexible.
Unified systems reduce complexity and operational errors.
Design plants for in-house maintenance to lower OPEX and downtime.
Despite its technical success, the Envia facility ceased operations in 2018 due to economic and supply-side constraints. However, key systems were repurposed in a smaller-scale renewable natural gas (RNG) facility—demonstrating the durability and adaptability of Velocys technology.
Legacy impact:
Velocys proved its microchannel FT reactors can deliver:
This project remains a milestone in waste-to-fuel innovation and the commercial validation of distributed GTL solutions.
Velocys built and operated the first commercial-scale GTL plant using landfill gas. The project validated Fischer-Tropsch technology for converting renewable waste gas into fuels—proving its commercial viability with over 6,000 runtime hours and more than 1.6 million liters of product delivered.
Velocys is the only FT licensor with proven commercial-scale GTL plant runtime using renewable feedstocks.
The Envia project operated for more than 6,000 hours, producing over 1.6 million liters of renewable fuels.
This facility set a U.S. first—the only operational commercial-scale GTL plant using landfill gas.
