The contract was announced and ordered through Advanced Combustion and Process Controls, the oil producer's prime contractor and ClearSign's representative in Southern California.

The results of the testing were independently confirmed by the customer and Advanced Combustion and Process Controls. This project consisted of retrofitting multiple units, including larger capacity units, and brought them in line with requested performance characteristics. This multi-phase project is the first application of ClearSign’s technology for the ground flare market. The companies and contractor are in discussions for future flare projects.

"With the close of this initial project we have penetrated a new market vertical and demonstrated a broader application for our Duplex technology. Our initial analysis shows that there are over 2000 enclosed ground flares in the US alone that would greatly benefit in reduced emissions through the use of ClearSign's Duplex technology," said Steve Pirnat, ClearSign's Chairman and CEO. "At the onset of the project we were presented with a challenging emissions situation and were able to provide a solution for the producer with an application of our Duplex technology. We are extremely pleased that we are able to satisfy the customer's demanding performance requirements, and look forward to working with them on future projects."
