Biomass fuel technology is undergoing a period of rapid innovation that is reshaping the economics of renewable power generation from organic materials. Insights published by Market Research Future indicate that the Biomass Power Market was valued at USD 137.81 billion in 2024, with forecasts projecting USD 143.87 billion in 2025 and USD 221.3 billion by 2035, representing a 4.4% CAGR throughout the forecast period. This growth is powered significantly by advances in how biomass is converted into useful energy—improvements that are narrowing the cost gap with fossil fuels and expanding the range of feedstocks that can be economically utilized.
The technology dimension matters because biomass is not a single fuel but a diverse category of organic materials, each with different moisture content, energy density, ash composition, and combustion characteristics. The conversion technology determines which feedstocks can be used, what emissions profile results, and what capital and operating costs are incurred. As conversion technologies improve, the addressable feedstock pool expands and the economics of biomass power strengthen.
Combustion: The Established Foundation
Combustion technology holds the largest market share in the biomass sector, leveraging organic material to produce energy through a well-understood process with established infrastructure. Direct combustion in boilers produces steam that drives turbines, a configuration that has powered the forest products industry for decades and now supplies electricity to grids in Europe, North America, and Asia.
The dominance of combustion reflects its maturity and reliability rather than its efficiency. Modern combustion plants incorporate improvements in boiler design, combustion control, and emissions treatment that have substantially reduced pollutant output compared with older installations. Co-firing—blending biomass with coal in existing power plants—has emerged as a lower-capital pathway to biomass utilization, allowing utilities to reduce carbon intensity without constructing entirely new facilities. Drax Group's conversion of its UK power station from coal to biomass stands as one of the largest examples of this transition, and the company reported 7.0 TWh of biomass generation in the first half of 2026 with a new biomass CfD from April 2027 allowing dispatch of up to 2.6 GW according to system needs.
Gasification: The Efficiency Frontier
Gasification is the fastest-growing technology in the biomass sector, converting organic material into syngas that can be used for power generation and other applications. Unlike combustion, which releases energy as heat, gasification produces a combustible gas that can be burned in engines, turbines, or fuel cells, enabling higher electrical efficiency and greater flexibility in plant configuration.
The appeal of gasification lies in its potential to achieve higher conversion efficiencies than combustion, particularly at smaller scales where conventional steam cycles lose efficiency. Advances in gasifier design, syngas cleaning, and process control have improved reliability and reduced tar formation, which historically limited gasification's commercial viability. Growing concerns about greenhouse gas emissions and the need for alternative energy solutions are propelling gasification to the forefront as an innovative and environmentally friendly option within the biomass power landscape.
The technology also opens pathways to produce liquid fuels and chemicals from biomass, extending its relevance beyond power generation. In 2024, it was estimated that technological advancements could increase biomass energy output by up to 40%, with gasification contributing significantly to that potential.
Anaerobic Digestion: Waste-to-Energy Integration
Anaerobic digestion is gaining traction as an emerging technology, converting organic waste into biogas through the action of microorganisms in the absence of oxygen. This method offers an effective way to manage waste while providing a clean energy source, appealing to industries aiming for sustainability.
The technology is particularly well-suited to agricultural residues, food processing waste, and municipal sewage sludge—feedstocks that would otherwise require disposal. Biogas can be burned directly for heat and power or upgraded to biomethane for injection into natural gas networks or use as vehicle fuel. The dual benefit of waste management and energy production makes anaerobic digestion attractive to policymakers seeking solutions that address multiple objectives simultaneously.
As interest in renewable energy solutions continues to rise, the anaerobic digestion segment showcases significant potential for growth, particularly with increasing investments and innovations aimed at improving efficiency. Advances in digester design, microbial culture management, and biogas upgrading are reducing costs and improving output, making the technology more competitive with alternative waste treatment and energy options.
Feedstock Technology and Supply Chain Innovation
Technology extends beyond conversion equipment to feedstock preparation and supply chain management. Woody biomass requires chipping, drying, and densification to achieve consistent quality for combustion or gasification. Pelletization has emerged as a key enabling technology, converting low-density biomass into dense pellets that can be transported economically over long distances and fed into automated combustion systems.
Enviva Holdings expanded its production capacity by acquiring a new facility in the southeastern United States in September 2025, strengthening its supply chain for wood pellets and reflecting the growing importance of feedstock logistics in the biomass value chain. The acquisition not only increases output but also improves distribution efficiency, allowing the company to meet growing demand for biomass energy.
Agricultural residues present different technical challenges. Their seasonal availability, variable moisture content, and higher ash content require preprocessing to ensure consistent combustion. Advances in baling, storage, and pretreatment are making agricultural residues increasingly viable as a feedstock, contributing to the rapid growth of this segment. The diversity of feedstocks not only supports local economies but also contributes to waste management solutions, creating value from materials that would otherwise be discarded.
Sustainability Technology and Certification
Technology is also being deployed to verify and document sustainability, an increasingly important requirement in European and North American markets. Orsted issued a Forest Biomass Policy in February 2026 requiring 100% certified forest biomass for bioenergy and BECCS applications, with sustainable-residue sourcing, independent audits, regeneration requirements and biodiversity safeguards governing biomass procurement. Such commitments reflect the industry's recognition that biomass's environmental credentials depend on responsible sourcing, and that technology-enabled traceability is essential to demonstrating compliance.
Orsted also reported completing a 98% emissions-reduction transformation with 99% renewable energy production in November 2025, citing conversion of its remaining heat-and-power plants to certified sustainable biomass. This achievement illustrates how technology, sourcing standards, and operational discipline combine to deliver verifiable sustainability outcomes.
Carbon Capture and the Negative Emissions Opportunity
The integration of carbon capture with biomass combustion—bioenergy with carbon capture and storage, or BECCS—represents one of the most significant technology frontiers. Because biomass absorbs carbon dioxide during growth and releases it during combustion, capturing and storing that carbon creates net negative emissions. Drax Group announced a partnership with a leading technology firm in August 2025 to develop advanced carbon capture and storage solutions, positioning itself as a frontrunner in the biomass sector as regulatory pressures mount for carbon reduction.
The economics of BECCS depend on carbon pricing mechanisms and policy support, but the technology offers a pathway for biomass power to transition from low-carbon to carbon-negative, potentially commanding premium prices in markets that value negative emissions.
Digitalization and Operational Optimization
Digital technologies are increasingly embedded in biomass operations. Orsted launched a new initiative in July 2025 aimed at integrating artificial intelligence into its biomass operations, expected to optimize energy production processes and improve operational efficiencies. By leveraging AI, companies can improve combustion control, predict maintenance needs, and optimize feedstock blending—all of which contribute to lower costs and higher reliability.
Challenges Facing Technology Adoption
Technology adoption faces several constraints. Capital costs for advanced conversion technologies remain substantial, limiting deployment to larger facilities or those with access to favorable financing. Feedstock variability complicates technology standardization, as equipment designed for one biomass type may perform poorly with another. The skills required to operate advanced gasification and anaerobic digestion systems are scarce, creating operational challenges. And the policy environment, while generally supportive, varies significantly across jurisdictions, creating uncertainty for long-term technology investments.
Future Outlook
The trajectory toward 2035 points toward continued technology refinement. Opportunities lie in the development of advanced biomass gasification technologies that further improve conversion efficiency, expansion of biomass supply chain logistics through improved preprocessing and densification, and investment in hybrid biomass-solar energy systems that combine dispatchable biomass generation with low-cost solar production. Fortum's approval of approximately €85 million to retrofit its Zabrze CHP plant in Poland for biomass and refuse-derived fuel, reducing coal capacity by 0.1 GW and targeting an annual reduction of approximately 280,000 tonnes of direct fossil CO₂ emissions, illustrates how technology retrofits can extend the life of existing assets while cutting emissions. Biomass fuel technology has become a genuine source of competitive advantage, and its evolution will shape the US Water Desalination Market as conversion efficiency improves and feedstock flexibility expands.
