ClearSign Secures 32-Burner Engineering Order from Global Supermajor

By: ACCESS Newswire

Planned Retrofit of Two Process Heaters at a California Refinery Underscores Growing Adoption of ClearSign's Higher Efficiency, Low-Emission Combustion Solutions

TULSA, OK, OK / ACCESS Newswire / October 7, 2025 / ClearSign Technologies Corporation (Nasdaq:CLIR) ("ClearSign" or the "Company"), a leader in advanced combustion and sensing technologies that help industrial operators dramatically reduce emissions, increase efficiency and safety, and support the use of cleaner fuels including hydrogen, today announces that it has received the initial CFD and engineering order from a supermajor refiner as the first phase of a process heater retrofit for a total of 32 ClearSign Core™ burners to be installed in one of its California refineries.

"We are pleased to announce a new order for another large-scale project from a supermajor refiner," said Jim Deller, Ph.D., Chief Executive Officer of ClearSign. "This is another new and major client for ClearSign, and, assuming we are successful in the completion of this project, it will provide a new field installation in one of our key target markets. We believe that this is further validation that our technology is continuing to gain recognition and momentum in the refining industry."

The initial CFD and engineering order was received directly from the customer for burners to be installed in two heaters in the supermajor refiner's California facility. The Company expects the project to commence imminently and be rolled out in phases over the coming 15-18 months.
