Tulsa, OK, February 23, 2023 — ClearSign Technologies Corporation (Nasdaq: CLIR) (“ClearSign” or the “Company”), an emerging leader in industrial combustion and sensing technologies that improve energy and operational efficiency, and safety while dramatically reducing emissions, today announces that Susanne Meline is stepping down from the ClearSign Board of Directors.  Concurrently, the Company announces the appointment of industry veteran Catharine de Lacy to the open board position.


Catharine de Lacy is a widely recognized expert in ESG/Sustainability initiatives, public affairs, corporate governance, and risk management.  She is known for her track record working with companies to enhance relationships with regulatory authorities, investors, suppliers and customers and reduce cycle time to market for new products. Ms. de Lacy is well versed across diverse industries having worked for both public and privately held companies including Albemarle Corporation, the Clorox Corp., Sun Products, Cabot Corp, AlliedSignal, and Occidental Petroleum Corp. in her capacities of a Corporate Officer and Global VP.

Catharine is the co-founder and Managing Director of Riar Associates, LLC, a management consultancy where she continues to work as a business advisor and subject matter expert on ESG, sustainability, business strategy, public policy and advocacy, communications, and risk management matters for public and private companies, banking and investment firms, professional services firms, and nonprofit organizations. She is a former board member of TORC Oil & Gas, Ltd. (TSX:TOG), and is currently serving as a board member of privately-held NTES LLC, which provides strategic, financial, and operations management expertise in evolving energy markets and real estate investment; a member of the Environmental Law Institute’s Leadership Council; and in the Executive Advisory Council of the Responsible Battery Coalition. Ms. de Lacy also regularly contributes to ESG educational programs as a board member of the National Association of Corporate Directors’ Carolinas Chapter and leads its Member Engagement Committee.  She holds a Board Certificate in ESG from UC Berkeley’s Law School, is a Certified Director through the Harvard Business School, holds a certificate in Risk Governance from the DCRO, and is also a Qualified Risk Director®.  Ms. de Lacy received a B.A. from Merrimack College, and an M.S. from Tufts University.


“I want to thank Susanne for her five years of service and support of ClearSign,” said Jim Deller, Ph.D., Chief Executive Officer of ClearSign.  “Over her tenure, Susanne has led every board committee at ClearSign, including serving as our Lead Independent Director, and has been integral to achieving the best possible results in all of our capital raises.  I have appreciated her voice and counsel over the years and believe she has left the company in a good position to further our commercial growth,” continued Dr. Deller.


“I am very pleased to welcome Catharine de Lacy to the ClearSign board.  I look forward to working with her and the benefits of adding her industry experience and ESG-related capabilities to our collective board expertise,” said Jim Deller, Ph.D.


“I am proud of the advancements that ClearSign has made over my time serving on Board,” said Susanne Meline.  “I am excited about the addition of Catharine to the Board, and her potential to assist the Company’s future commercial growth including connecting with customers, resources, investors and other constituents who seek out the Company, its securities and its products not only for their own merit but also due to their ability to reduce the emission of toxic airborne pollutants.  The recent sales of boiler burners show that business segment is starting to gain traction while the continued execution of commercial orders in process burners will help the proliferation of the Company’s technology.  I have full confidence in Jim Deller’s leadership and look forward to the contributions that Catharine de Lacy can bring to the Board and Company.”
