First finished products at ENVIA Energy's GTL plant

Velocys plc (VLS.L), the company at the forefront of smaller scale gas-to-liquids (GTL), is pleased to report the successful production of first finished, saleable products at ENVIA Energy's GTL plant in Oklahoma City. Fischer-Tropsch products are now being fractionated to produce premium, renewable waxes, diesel and naphtha, meeting customer product specifications.

The on-site operations team has completed the debugging of several units of the plant - activities that are routine during the start up of a plant of this complexity - and is continuing the implementation of the pre-planned programme of ramping up production to target operational capacity over the coming months.

David Pummell, CEO of Velocys, said:

"We're pleased that another milestone has been successfully achieved at the ENVIA Oklahoma plant. The exceptional quality of these products further verifies the performance of our technology and underlines its ability to deliver a slate of high value premium products at smaller scales."
