ENVIA Energy

First finished, saleable products achieved at commercial reference plant.

ENVIA Energy is a joint venture that was announced in March 2014 to produce renewable fuels and chemicals from biogas and natural gas using GTL. ENVIA Energy's Oklahoma City GTL project is located adjacent to the East Oak landfill site and uses a combination of landfill gas and natural gas as feedstock. The plant deploys Velocys' full-scale commercial Fischer-Tropsch (FT) reactors.

Under a secondment agreement with ENVIA, Velocys’ team of experienced GTL operations managers, operators and engineers were deployed on site in Oklahoma City during the second half of 2016. This Velocys operations team, which served under the ENVIA Plant Manager, brought essential support to the ENVIA team through commissioning, start-up and early stage operations. The Velocys team brought a wealth of operational GTL plant expertise including commissioning and plant performance optimisation, drawing on experience gained at a number of large-scale commercial GTL projects as well as from the Velocys pilot plant. A small number of key Velocys staff are being seconded to ENVIA over a longer transition period and the wider Velocys team remains available to support ENVIA operations, as needed.

First finished, saleable products have been produced at the plant - premium, renewable waxes, diesel and naphtha. The fuels produced at the plant are expected to qualify under the Renewable Fuels Standard (RFS) and generate tradeable credits in the form of Renewable Identification Numbers (RINs).

The performance data (for example, methane selectivity, liquid production, carbon monoxide conversion and activity index) that are available from the ENVIA plant meet the performance expectations set using models based on laboratory and pilot studies. Targets for the conversion of syngas to FT products and the yield of liquid products were achieved within 12 hours of the first start-up of the FT modules (the equivalent of one shift of plant operators).

The operations team is continuing to implement the pre-planned procedure of ramping up production to target operational capacity over the coming months.

In parallel, we are starting to welcome key stakeholders to visit the plant and witness first-hand Velocys’ technology in action.
