Spain Flue Gas Desulfurization Market Overview, 2031

Key Insights

• According to the research report, "Spain Flue Gas Desulfurization Market Outlook, 2031," published by Bonafide Research, the Spain Flue Gas Desulfurization Market is anticipated to add to more than USD 56.24 Million by 2026-31.
• Spain's Flue Gas Desulfurization (FGD) market is driven by stringent environmental regulations governing sulfur dioxide (SO₂) emissions from industrial combustion sources. Spain's climate and energy strategy supports a rapid transition toward cleaner energy, targeting 48% renewable energy consumption by 2030 and climate neutrality by 2050. As coal-fired generation declines, demand for FGD systems is increasingly concentrated in industrial sectors such as cement, steel, refining, waste-to-energy, and biomass.
• Spain completed the phase-out of conventional coal-fired power generation in 2025, with the remaining coal assets either retired or converted to alternative fuels. As a result, demand for new utility-scale FGD installations has declined, while retrofit, modernization, and maintenance opportunities are increasingly concentrated across industrial combustion facilities.
• Spain's cement industry remains an important end-use sector for industrial emission-control systems. Rising cement demand together with compliance under the Industrial Emissions Directive (IED) continues to support investment in air pollution control equipment, including sulfur dioxide and particulate emission reduction technologies.
• Spain's steel industry continues to invest in environmental upgrades across integrated steelmaking operations. Projects at ArcelorMittal's Asturias facilities, including sinter plant modernization, dust collection systems, and flue gas treatment upgrades, continue supporting demand for industrial emission-control technologies.
• Spain's waste-to-energy and biomass sectors are emerging growth areas for flue gas cleaning technologies. Recent biomass boiler projects supplied by Valmet and DP CleanTech incorporate advanced flue gas treatment systems, while existing waste-to-energy facilities continue upgrading emission-control equipment to comply with increasingly stringent environmental standards.

Market Outlook

• Spain's Flue Gas Desulfurization market is evolving from a utility-driven market toward an industrial emission-control market following the completion of the country's coal phase-out. Future demand is expected to be supported primarily by retrofit projects across cement, steel, refining, biomass, waste-to-energy, and other industrial combustion facilities operating under increasingly stringent European emission standards.
• Although coal-fired generation has largely disappeared from Spain's electricity mix, remaining industrial combustion facilities continue to require flue gas treatment systems to comply with environmental regulations. Biomass and waste-to-energy plants are emerging as important applications for modern flue gas cleaning technologies.
• Spain's cement industry continues to generate stable demand for flue gas treatment systems as producers invest in emission-control equipment to comply with Best Available Techniques (BAT) under the Industrial Emissions Directive.
• The Spanish FGD market is increasingly characterized by retrofit, modernization, digital monitoring, and aftermarket services across cement, steel, refining, biomass, and waste-to-energy facilities as operators focus on extending equipment life while maintaining regulatory compliance.

Policies & Regulatory Landscape

• Spain's emissions projections show significant SO₂ reductions. Compared to 2005 levels, Spain achieved a -91% reduction in SO₂ emissions by 2025 and projects -92% by 2030. SO₂ emissions are projected at 107 kilotonnes in 2025 and 98 kilotonnes in 2030, down from 1,207 kilotonnes in 2005. The program aligns with Spain's commitments under the UNECE Convention on Long-Range Transboundary Air Pollution.
• Spain implements the EU Industrial Emissions Directive (IED) through its national environmental permitting framework. The revised IED strengthens emission-control requirements across industrial sectors, supporting continued investment in flue gas treatment technologies.
• Spain formally brought forward its coal phase-out date from 2030 to 2025. As of December 2025, only two coal-fired units remained in operation. Aboño Unit 1 (360 MW) was retired in December 2025, while Aboño Unit 2 (556 MW) was converted to natural gas. Spain's Just Transition Strategy was designed to manage the phase-out of publicly subsidized coal production and coal-fired plants.
• In June 2025, Royal Decree 214/2025 of 18 March 2025 was issued creating the carbon footprint reporting framework, allowing authorities to include carbon footprint considerations as environmental criteria in tender procedures. Spain requires large companies to report their carbon footprints and develop GHG emissions reduction plans.
• Several Spanish regions have implemented air pollution taxes covering sulfur dioxide (SO₂) and nitrogen oxides (NOₓ) emissions from industrial installations, with tax-free thresholds and rates per tonne. Galicia has a tax on atmospheric pollution covering SO₂ and NOₓ.
• Spain must transpose the EU's revised Air Quality Directive and IED requirements into national law. The IED revision strengthens the EU's industrial-emissions framework in line with the European Green Deal and the zero-pollution ambition for air, water and soil.

FGD Procurement and Industry Impact

• Spain's FGD procurement market is increasingly driven by retrofit, modernization, and aftermarket projects across cement, steel, refining, and waste-to-energy sectors rather than new coal-fired power plant installations. The completion of the coal phase-out in 2025 has fundamentally reshaped the market toward industrial applications.
• Spain's cement industry continues generating procurement opportunities through modernization of emission-control equipment, driven by higher production activity and compliance with evolving environmental regulations.
• Steel producers continue investing in gas-cleaning infrastructure, including sinter plant upgrades, dust collection equipment, and flue gas treatment systems to improve environmental performance and comply with BAT requirements.
• Spain's waste-to-energy and biomass sectors represent growing procurement opportunities for flue gas cleaning technologies. Valmet received an order from Saica Group to supply a biomass boiler and flue gas cleaning system for its plant in Zaragoza, scheduled for handover at the end of 2026. DP CleanTech was awarded a major contract for a 50 MWe biomass boiler and flue gas cleaning system for the La Robla Green Project in Castilla y León.
• Aftermarket services continue to represent an important revenue stream for FGD suppliers through replacement components, absorber refurbishment, corrosion-resistant materials, instrumentation, inspection services, and long-term maintenance contracts supporting Spain's installed industrial emission-control base.
