Emerging Opportunities For Advanced Flue Gas Treatment Systems

• Digitalization and AI-Driven Optimization: A primary opportunity is materializing from the integration of digital technologies, specifically IoT and Artificial Intelligence. AI-driven platforms can meticulously optimize combustion processes in real-time, resulting in substantial efficiency improvements. For example, a 2025 analysis of AI integration in waste-to-energy incinerators showed a power generation efficiency increase of over 1.7% in the flue gas treatment systems market. Moreover, the same analysis reported that the plant’s heat rate was reduced by approximately 58 kcal/kWh. This level of digital optimization not only lowers operational expenditures but also refines the precision of emission control, thereby creating a compelling value proposition for operators.
• By-Product Valorization: A second, equally powerful trend is the strategic conversion of captured pollutants into commercially viable products. Flue gas desulfurization (FGD) systems, for instance, produce synthetic gypsum, which is a highly sought-after raw material in the construction sector. In fact, global demand for FGD gypsum specifically for the wallboard industry is projected to reach 99.5 million tons per year in 2025. Similarly, captured fly ash is being increasingly repurposed for use in cement and concrete production. This "waste-to-value" model effectively transforms a compliance-related expense into a profitable revenue stream, aligning perfectly with circular economy objectives.

Circular Economy Principles Transforming Industrial By-Products Into Assets

A pivotal aspect currently defining the flue gas treatment systems market is the adoption of circular economy models, which focus on valorizing industrial by-products. This strategic shift is turning former waste streams into valuable assets, thereby creating a strong economic incentive for investment. The market for synthetic gypsum, a direct by-product of FGD systems, is particularly robust. For 2025, the global synthetic gypsum market is estimated to reach a value of US$ 1.75 billion. The demand is primarily fueled by the construction sector, where FGD gypsum is a key component for drywall and cement. Specifically, the global demand from the wallboard industry alone is projected to reach 99.5 million tons per year in 2025.

Furthermore, this trend is reinforced by the expanding reuse of other captured materials in the flue gas treatment systems market. The global fly ash market, another crucial by-product, achieved a value of US$ 13.9 billion in 2024. In the United States alone, total fly ash utilization is forecasted to increase to 27.8 million short tons by 2039. In addition, emerging carbon dioxide utilization technologies are creating new commercial pathways for captured CO2 in products like fuels, chemicals, and polymers. To illustrate, the total annual production capacity of polycarbonate resin using captured CO2 has already reached 1 million tons. The value of the U.S. carbon dioxide utilization market was estimated at US$ 1.68 billion in 2024 and is projected to expand to US$ 4.52 billion by 2032.

Blue Hydrogen Production Surge Is Creating A New Demand Frontier

The rapid acceleration of blue hydrogen production represents a significant and defining new demand driver for the flue gas treatment systems market. Critically, blue hydrogen is produced using steam methane reforming (SMR), a process that inherently generates a CO2-rich flue gas stream. This stream requires capture and treatment, directly linking hydrogen production to emission control. As nations invest heavily in hydrogen infrastructure, the corresponding need for these systems is soaring. In 2025, the U.S. blue hydrogen sector is expected to see over 1.5 million tons per annum of capacity reach a final investment decision, signaling a massive new demand pipeline.

Moreover, this growth of the flue gas treatment systems market is supported by substantial capital investments and clear project developments. For example, ExxonMobil's Baytown facility is targeting a 1 billion cubic feet per day hydrogen capacity, coupled with a 98% CO2 capture rate. Likewise, Linde's US$ 1.8 billion facility in Beaumont is engineered to sequester 1.7 million tons of CO2 annually. These projects clearly underscore the scale of the opportunity. By the end of the second quarter of 2025, the total active and pipeline CCS capacity linked to blue hydrogen production had reached 125 million CO2 tons per year. The U.S. Department of Energy has also announced US$ 7 billion in funding for clean hydrogen hubs, further cementing future demand.
