"We are pleased to announce this engineering order for a large multi burner heater retrofit from a name brand petroleum company," said Jim Deller, CEO of ClearSign Technologies.

ClearSign’s technologies are designed to enhance combustion systems and fuel safety systems across various industries including energy, commercial/industrial boiler, chemical, petrochemical, transport and power sectors.

The announcement comes as industrial operators face increasing pressure to reduce emissions while maintaining operational efficiency. The company stated in its press release that its technology helps industrial operators reduce emissions, increase efficiency and safety, and support the use of cleaner fuels including hydrogen.

The company experienced a significant increase in revenue, reporting $133,000 for the quarter, compared to $45,000 in the same period last year. Despite this revenue growth, ClearSign did not meet earnings per share expectations, according to analysts’ forecasts. In another update, the company announced it has regained compliance with Nasdaq’s board and audit committee composition requirements after recent changes to its board of directors. This follows a notice from Nasdaq indicating non-compliance due to board member resignations.
