Fuel Tech, Inc., a company primarily known for its air pollution control (APC) and boiler optimization technologies, is quietly sitting on a potential gold mine that seems to have eluded the discerning eyes of Wall Street analysts. While the recent Q1 2024 earnings call focused on predictable themes like regulatory changes and the promising Dissolved Gas Infusion (DGI) technology, a closer look at the Q1 2024 Earnings Call Transcript reveals a subtle shift in the company's FUEL CHEM segment, a shift that could herald a significant resurgence in this underappreciated area of the business.

For years, Fuel Tech's FUEL CHEM segment has been viewed as a legacy business, tied to the declining coal-fired power generation industry. Warmer weather patterns and plant outages have further contributed to the segment's declining revenues, painting a picture of a business slowly fading into irrelevance. However, CEO Vince Arnone's comments on the Q1 earnings call suggest a different story, one characterized by renewed interest and a potential uptick in demand for FUEL CHEM's unique chemical treatment programs.

Arnone specifically highlighted "multiple additional FUEL CHEM development opportunities" that the company is pursuing, opportunities that could drive incremental revenue growth in the second half of 2024 and beyond. He went on to emphasize that these opportunities extend to both coal and biomass fired boilers, suggesting a broader market reach than previously anticipated.

Diversification Beyond Coal

This shift in the FUEL CHEM narrative is significant for several reasons. First, it challenges the prevailing assumption that the segment is solely dependent on the fate of the coal industry. By expanding its focus to biomass fired boilers, Fuel Tech is tapping into a growing market driven by renewable energy initiatives and a focus on sustainable fuel sources. This diversification of the FUEL CHEM customer base could significantly mitigate the risks associated with the coal industry's decline.

Second, the pursuit of "multiple" new development opportunities suggests a proactive approach to business development, a departure from the more reactive stance the company has taken in recent years. This proactive approach is further reinforced by Arnone's excitement about a new demonstration order for FUEL CHEM at a large coal-fired unit in the Western US, a demonstration that could translate into annualized revenues of $1.5 million to $2 million at historical gross margins.

This demonstration, coupled with ongoing discussions for a second coal-fired unit demonstration and potential opportunities with biomass-fired boiler operators, paints a picture of a FUEL CHEM segment poised for a potential turnaround.

Projecting the FUEL CHEM Resurgence

While it's too early to quantify the full impact of these new development opportunities, the potential for a FUEL CHEM resurgence is undeniable. Let's hypothesize, based on Arnone's comments, that Fuel Tech secures at least two new commercial accounts from these ongoing demonstrations and discussions. At an average annual revenue of $1.5 million per account (conservatively using the lower end of Arnone's estimate), this translates to $3 million in additional annual revenue for the FUEL CHEM segment. This represents a potential 11.5% increase over the segment's 2023 revenue of $26 million, a significant jump for a business previously considered stagnant.

Furthermore, the potential for higher-than-average revenue from these new accounts, coupled with the possibility of securing additional accounts beyond the two hypothesized here, suggests an even greater upside for FUEL CHEM.

Implications of a FUEL CHEM Revival

The implications of a FUEL CHEM resurgence are far-reaching. First, it would provide a substantial boost to Fuel Tech's overall revenue growth, exceeding the modest growth projected in the company's 2024 guidance. Second, it would contribute to higher profitability, as FUEL CHEM historically operates at attractive gross margins. Finally, it would diversify the company's revenue streams, reducing its dependence on the APC segment and its associated regulatory uncertainties.

This potential FUEL CHEM revival adds another layer of intrigue to Fuel Tech's story. While the company continues to build momentum with its DGI initiative and navigate the complex regulatory landscape for its APC segment, the FUEL CHEM segment is emerging as a potential hidden gem. The renewed focus on business development, coupled with a growing and diversifying customer base, could propel the segment back to its former prominence, creating a powerful engine for growth and profitability for Fuel Tech in the years to come.
