Thank you, Devin. Good morning, and I'd like to thank everyone for joining us on the call today. We were pleased with our business progress along several fronts in 2023. Total revenue of $27.1 million was within our previous guidance range and represented our highest annual revenue level since 2019. Our APC business segment performed well, reflecting more than $8.3 million of new project awards during the year, and we ended the year with a backlog of $7.5 million at December 31, 2023. Further, we were pleased to announce the additional $2.1 million in new contract awards yesterday. We completed a successful trial of our dissolved gas infusion technology in an aquaculture setting, and we believe that we are well positioned to commercialize DGI in 2024. And lastly, we continue to maintain a conservative cost profile, with SG&A expenses up modestly from 2022 levels and ended the year in a strong financial position with $33.4 million in cash and investments and no long-term debt. We are most heartened by the progress we have made in our DGI business initiative in 2023. Last month, we announced the publication of a white paper that details the benefits of deploying DGI for oxygen injection at a shrimp farm in the United States. As a reminder, our DGI technology involves the efficient transfer of high concentrations of gas into a body of water through a patent saturator and a patent-pending injection array to drive chemical or biological reactions, such as for wastewater treatment, odor control and PH adjustment, or for process improvements in industrial applications, or in this case, aquaculture. Specifically, the use of DGI this location increased shrimp production compared to traditional aeration methods, and contributed to likely health improvements. Demand for shrimp is increasing globally, and inland shrimp farming is an important source to help meet the growing demand in a safe and sustainable manner, while reducing over fishing of the marine environment and lowering the overall carbon footprint by reducing transportation costs. By deploying DGI, producers now have an opportunity to improve stock health and yields while achieving more efficient operations immediately adjacent, to their customer locations. At present, we are utilizing DGI to deploy oxygen into bodies of water. However, we believe that DGI can be applicable for other gases as well such as, CO2 and Ozone. DGI's benefits include the precise control of dissolved oxygen levels, for all process applications and ability to extend plant capacity without major capital expansion or capital outlay odor reduction, and minimal bubble formation for extended residence time. We believe that DGI can be applied across several end markets including pulp and paper, food and beverage, chemical or petrochemical, water and wastewater treatment, horticulture and aquaculture. As a follow up, to the publication of our DGI white paper, we presented our technology and favorable findings from our aquaculture demonstration at the Aquaculture America 2024, conference last month. This annual conference provides members and participants, with the opportunity to stay current with technical advancements and inspect the latest in products and services, in the aquaculture industry. In recent months, in part driven by the interest generated after publishing and presenting our demonstration results, we have received a notable increase in inquiries regarding our DGI technology, from potential customers in multiple end markets including, municipal odor control, pH control, for -- municipal and industrial applications, agricultural applications and additional aquaculture applications. We are currently in negotiations, with potential customers regarding on-site demonstrations of DGI and we are targeting to sign our first commercial contract for DGI in 2024. Lastly, to further expedite the introduction of DGI into end markets, we have recently hired a former water and wastewater treatment executive on a consulting basis. This individual is well experienced in the application of Dissolved Gas Technologies and we look forward to his contributions over these next several months. Let's now, please spend a few minutes discussing our FUEL CHEM and APC business segments. As we had expected, revenues for our FUEL CHEM segment declined from 2022 levels, due to the effects of warmer weather across the US, which impacted overall demand and related unit dispatch. However, segment gross margin was essentially unchanged for the year, and remain at historical levels. Our base FUEL CHEM unit count, remains intact as we enter 2024, and for the first time in a few years, I'm very pleased to say that we are currently pursuing multiple additional FUEL CHEM development opportunities, which could provide incremental revenue contribution in 2024 and beyond. These opportunities are for both coal and biomass fired boilers. For 2024, excluding any material incremental revenue from new business development activities, we would expect that FUEL CHEM revenue would remain at parity, with 2023. With respect to international opportunities for the FUEL CHEM segment, we continue to follow the opportunity to expand the provision of our chemical technology in Mexico, be our partner in that country, to address the emissions created by the burning of high-sulfur fuel oil, which is being undertaken without the necessary environmental remediation, and at the expense of the health of surrounding communities. In 2023, we executed a two year extension to the program that we currently have in place at one facility. With the upcoming presidential election in Mexico in June of this year, we believe that political pressure is building in favor of our implementation of our FUEL CHEM program at additional facilities in this country. Our partner is currently in discussions with the state-owned utility CFE regarding the application of our technology at several units. Now turning over to our APC segment. We benefited in 2023 from the continued adoption of our Ultra SCR, SNCR and FTC emissions control solutions at natural gas and coal-fired units in the US, Europe, South Africa and the Pacific Rim, independence of the potential impact of favorable regulatory outcomes, which I will discuss here shortly. We remain well positioned to take advantage of current industrial end market trends, which include plant capacity expansion across several industries, the incentivized use of small turbines to replace traditional less clean power generation, the development of the biocarbon industry, the continued emphasis on the decarbonization on a global basis and the focus on using our ULTRA System as a safe source of ammonia for SCRs at hospitals and universities across the US. On the regulatory front, we continue to monitor progress related to the adoption of the US EPA's Cross-State Air Pollution Control rule to meet the Good Neighbor requirements of the Clean Air Act, which we believe can be a potential catalyst for APC growth in 2024 and for the remainder of this decade, as utility and industrial customers explore ways to further reduce NOx emissions. We have in fact received and responded to several requests for budgetary proposals, as customers prepare to address the upcoming compliance requirements as part of their capital budgeting requirements for 2024 and beyond. As discussed on previous calls, the rule currently obligates 23 states to reduce emissions of nitrogen oxides from power plants and certain industrial facilities to limit their impact on downwind states. The ultimate timing of the effectiveness of the rule is uncertain because several upcoming effective states and sources have challenged the efficacy of EPA's proposed regulation in multiple cohorts and stays of the effectiveness of their – of the rule have been issued for many upwind states. Last month, oral arguments were presented to the Supreme Court by both parties and we will closely monitor the potential impact of the Supreme Court's ruling on whether to stay the rule for all states when it is issued later this year. In addition to the Good Neighbor rule, we are also watching the progress of EPA's rule for large municipal waste combustors, which is independent of the Good Neighbor rule. This rule reduces the nitrogen oxide emissions requirements for large municipal waste combustor units. Fuel Tech has had a long history of assisting this industry in meeting their compliance requirements. And we have had discussions with customers in this segment to support them in their compliance planning. The municipal waste combustor rule is currently in a public comment period with compliance deadlines expected sometime in the next three years. Based on our effective backlog at year end, the business development activities we are pursuing and our previously noted expectations for FUEL CHEM, we expect that total revenues for 2024 will exceed the total revenues recognized in 2023 of $27.1 million and we will provide further guidance as we move throughout 2024. This base case outlook excludes any material contributions from DGI, as we are still in the early stages of commercial commercialization, any significant contributions to APC from the above referenced EPA regulations and the impact of material business development activities for FUEL CHEM. Now in closing, I want to take – to thank the Fuel Tech team for their contributions to the improvement of our business in 2023. It is their continued hard work, passion and dedication that drive our ability to be successful. Additionally, I thank our shareholders for their continued support. We expect that 2024 will be an important year in the growth and evolution of Fuel Tech and we look forward to keeping everyone apprised of our progress. With that said, I would now like to turn the call over to Ellen to talk about our financial statements. Ellen, please go ahead.
