Biofuels in Gas Turbines: A Critical Review of Combustion and Emission Studies

Abstract The growing demand for sustainable energy makes biofuels attractive to be used as an alternative fuel source to the fossil based fuels in gas turbines. This critical review discusses the combustion and emission performance of various biofuels in gas turbine applications. The aim is systematic assessment of various alternative fuels like biodiesel, bioethanol, bio-oil, hydrogenated vegetable oil and Fischer-Tropsch compared to petroleum diesel in terms of their physicochemical properties, efficiency of combustion and emissions characteristics are evaluated. The authors
conducted a systematic literature review, which included 72 peer-reviewed studies published between 2006 to 2024, with data extraction and synthesis in the form of descriptive statistical reports and meta-analysis. According to the hypothesis, biofuels can match combustion and
related emissions performance of fossil fuels. Results from six extensive tables show it is possible to get about 97-99 % combustion efficiency with biofuels. Good performance has been demonstrated with bioethanol, achieving 30-50% NOx reductions and 85-98% CO reduction. Particulate reductions are 45-85% and nitrogen oxides increase by 8-16%. All biofuels have 78- 92% less direct CO2 emissions. Discussion shows that emission trade-offs, molecular structure effects and atomization quality play a critical role on performance. This technology is still facing difficulties, such as fuel property fluctuation, combustion unstability and economic barrier. This review establishes the technical viability of biofuels for use in gas turbines, with bioethanol and HVO considered being the most promising fuels for sustainable power generation and aviation.
