<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt"><FONT STYLE="color: black">SEATTLE, WA &ndash; AUGUST
2, 2012 - ClearSign Combustion Corporation (Nasdaq: CLIR),</FONT> an emerging leader in combustion and emissions control technology
for industrial, commercial and utility markets, reported today that it has successfully demonstrated the ability to apply its proprietary
Electrodynamic Combustion Control&trade; (ECC&trade;) technology to a combustion system without requiring an electrode to have
physical contact with the flame.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">According to Joe Colannino, the company&rsquo;s Chief
Technology Officer, this demonstration points the way to powerful new options for system designers to integrate ECC technology
into both retrofit and new build installations. ECC technology works by applying a computer-controlled, high-voltage electrical
charge to a flame in order to achieve improved control of flame shape, flame stability, flame chemistry and heat transfer in combustion
systems.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&ldquo;In our earlier efforts, we have applied charge
to the flame by mounting an electrically conductive fixture inside, or directly in contact with, the flame. While physical electrodes
may continue to be the preferred approach in many applications,&rdquo; Colannino explained &ldquo;the use of a 'non-contact electrode'
may simplify the job of retrofitting ECC technology to existing systems and/or designing it into new ones.&rdquo;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&quot;We have demonstrated several novel and very
effective approaches to transferring the pulsed charge into the flame region,&quot; said Colannino. &quot;One method involves transmitting
the charge into the larger flame through a smaller secondary or 'pilot' flame in contact with the main flame. We believe that this
'flame-on-flame' technique is unprecedented and we are also encouraged by the broader implications with regard to the electrical
characteristics and behavior of flames.&rdquo;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&quot;Charging the flame without physical contact
with the flame body significantly expands the design options available to manufacturers and system engineers. In some cases the
electrical charge can now be effectively applied at the air inlet, before the fuel and air mixture combust at the burner, simplifying
some system designs and enabling ECC technology to be more rapidly and easily integrated.&quot;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&nbsp;</P>

that will enable the practical commercial use of our technology while making it both convenient and cost-effective to implement,&rdquo;
Rutkowski emphasized. &ldquo;By eliminating one more design constraint, we simplify the adoption of our technology. This is the
kind of innovation that can accelerate market entry and allow us to address the broadest possible market.&rdquo;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&ldquo;Protecting enabling techniques for system design,
such as this, is a fundamental part of our intellectual property strategy, and we believe, further enhances our competitive position.&rdquo;
Rutkowski added. &ldquo;Advances such as non-contact electrodes make strong additions to our large and rapidly expanding intellectual
property portfolio.&rdquo;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 4.5pt">&ldquo;Our goal is to turn the economics of emissions
control on its head.&quot; said Rutkowski. &ldquo;We believe our technology will enable our customers to reduce multiple types
of emissions by suppressing them at the source and at the same time, will increase system efficiency, throughput and overall productivity.
The ability to combine increased efficiency with emissions control is unprecedented and, potentially, a sea change. We&rsquo;re
talking about a world where environmental compliance is no longer a cost but instead a source of additional profit and return on
invested capital. That&rsquo;s great news for both industry and the environment.&rdquo;</P>
