ClearSign Technologies Corporation, an emerging leader in industrial combustion and sensing technologies that improve energy, operational efficiency and safety while dramatically reducing emissions, today provides an update on operations for the first quarter ended March 31, 2022.

"I am encouraged by the recognition we are gaining in the industry said Jim Deller, Ph.D., Chief Executive Officer of ClearSign. "We have spent significant time this quarter meeting with customers, at industry conferences, in person and via web calls.  What has changed in these interactions is first, many have been requested by the customers or companies working on their behalf, secondly, we are entering into deeper discussions rather than an introduction of our technologies.  I do see growing recognition of our abilities in the industry.  Our goals are now to convert these inquires and proposals into orders for both our process burner and boiler burner product lines."     

Recent strategic and operational highlights during and subsequent to the first quarter of 2022 include:

Closed an underwritten public offering of Common Stock:  The Company closed an offering of 4,186,000 shares of its common stock at a price to the public of $1.11 per share. The total offering included 546,000 shares issued pursuant to the full exercise of the underwriter's over-allotment option.  Gross proceeds to ClearSign from this offering were approximately $4,646,460 before deducting underwriting discounts, commissions and other offering expenses.  ClearSign intends to use the net proceeds from the offering for working capital, research and development, marketing and sales, and general corporate purposes.

Awarded Grant from Department of Energy to Develop a Hydrogen Fueled Ultra Low NOx Process Burner: The Company was awarded a government grant through the Small Business Innovative Research (SBIR) program with the Department of Energy.  The goal of this project is to develop ultra-low NOx hydrogen burner technology which will enable the adoption of hydrogen fuel for industrial heating, leading to reductions in the industrial emissions of both carbon dioxide and nitrogen oxides. The project and funding are in phases.  The initial funding amount is approximately $250,000 and the project will last six months starting at the end of June. If needed, and upon completion of the Phase 1 work, the Company will be able to submit a follow-up proposal to continue the development work with a Phase 2 grant. Phase 2 grant funding can be up to $1.6 million for a two-year duration.

Announced Initial Order for Multi Heater Project from California Refinery:  The Company received an initial engineering order from a large independent national refiner as the first phase of a project to retrofit two process heaters for a total of twenty ClearSign Core™ burners in one of their California refineries. The order consists of engineering, drafting and CFD (Computational Fluid Dynamics) modelling of ClearSign Core burners operating in the destination heaters. The following phases of this project are expected to include a physical "first article" full size burner demonstration, then the supply of the twenty burners to be installed in the California refinery heaters.

Successfully Installed a Process Burner Order for a Super Major's European Refinery: The project consisted of engineering, fabrication, conducting a witness test and finally installing a replacement burner for a single burner process heater incorporating the ClearSign Core™ NOx reduction technology. In addition to meeting the requirements for this specific service, this order also serves as an initial demonstration of ClearSign Core's superior NOx emissions technology for deployment into refiners' fleet of global facilities to meet their emissions reduction goals.

Relocated Company Headquarters to Tulsa, OK: The Company's move to Tulsa provides both strategic and business development benefits.  Tulsa is the epicenter of the global high tech combustion industry, with a highly skilled workforce, and where leaders in the industry like ClearSign's partner Zeeco are based. Additionally, the Company has been awarded an incentive through the Oklahoma 21th Century Quality Jobs Act incentive program from the Oklahoma Department of Commerce.

Cash and cash equivalents were approximately $6,667,000 on March 31, 2022.
