SEATTLE, July 26, 2018 /PRNewswire/ -- ClearSign Combustion Corporation (Nasdaq: CLIR) ("ClearSign" or the "Company"), an emerging leader in industrial combustion technologies that improve energy and operational efficiencies while dramatically reducing emissions, today announced that it has signed a Non-Disclosure Agreement with an unnamed supermajor for the purpose of evaluating the Company's revolutionary Duplex™ combustion technology. ClearSign is actively working with the supermajor to identify equipment for an initial installation at one of its many refinery locations.

This is the second supermajor oil and gas company to evaluate and consider standardizing ClearSign's Duplex technology to existing heaters. As previously announced last November 27, 2017, ExxonMobil commissioned and completed a comprehensive set of qualification tests and is actively working with the Company to finalize plans for the deployment of Duplex at an initial refinery location.

Stephen Pirnat, ClearSign's Chairman and CEO, stated, "After achieving a key milestone with ExxonMobil last fall, we are encouraged that a second supermajor has decided to evaluate our Duplex technology for installation. We believe that this development serves as another important validation of our technology and represents an increasing commercial interest from global supermajors and a critical reinforcement for the deployment of our technology across an approximately $1 billion addressable market in the refinery, chemical and petrochemical industries."
