ClearSign Technologies Corporation announced that it has secured an engineering order for a fifth low‑emission retrofit flare burner and associated system components from a California energy company. The order covers a fully enclosed flare system to be installed in the San Joaquin Valley, with delivery scheduled for the third quarter of 2026.

The win adds a new customer to ClearSign’s growing list of retrofit projects and expands the company’s portfolio beyond its flagship process burners. By delivering quick‑turn, low‑emission flare systems, ClearSign can generate recurring revenue while its larger burner installations mature, supporting a broader strategy of diversified revenue streams.

ClearSign’s financial trajectory underscores the significance of the order. The company reported Q4 2025 revenue of approximately $3.6 million, a 510% year‑over‑year increase from Q4 2024, and projected full‑year 2025 revenue of about $5.2 million, up 44% from 2024. Although the company posted a net loss of $5.3 million in fiscal 2024, it maintains strong liquidity and a low debt‑to‑equity ratio. The new order is expected to contribute to continued top‑line growth and reinforce the company’s recurring‑revenue model.

Jim Deller, ClearSign’s CEO, said, “We’re pleased to continue to supply this key customer with advanced flaring solutions to modernize their fleet and operate within California’s clean air standards.” He added that the relationship validates the product line and positions ClearSign as a trusted provider of next‑generation, ultra‑low‑NOx combustion technology.

California’s stringent NOx regulations create a tailwind for low‑emission solutions, and ClearSign’s recent partnership with Zeeco, Inc. to launch a co‑branded burner line capable of firing natural gas and 100% hydrogen, further strengthens its competitive position. The company’s ongoing hydrogen‑fuel burner development, supported by a Department of Energy grant, aligns with the state’s clean‑energy trajectory.

The order demonstrates sustained demand for ClearSign’s technology, supports its strategic shift toward full flare systems and control upgrades, and represents a material development that could influence future revenue projections.
