This study investigates the performance and emission characteristics of biofuel blends in gas turbines, aiming to evaluate their feasibility as alternative fuels in aviation and power generation applications. With increasing environmental concerns and regulatory pressures to reduce greenhouse gas emissions, biofuels have emerged as a promising solution to enhance sustainability in the energy sector. The research examines various biofuel blends, including biodiesel and renewable diesel, in combination with conventional fossil fuels. Experimental analyses are conducted to assess key performance indicators such as thermal efficiency, power output, and combustion stability. Additionally, emission profiles, including nitrogen oxides (NOx), carbon monoxide (CO), and particulate matter (PM), are evaluated to determine the environmental impact of using biofuels in gas turbines. Results indicate that specific biofuel blends can achieve comparable performance to traditional fuels while significantly reducing harmful emissions. This study provides valuable insights into the viability of biofuel integration into gas turbine operations, contributing to the ongoing pursuit of cleaner and more sustainable energy solutions. The findings highlight the potential for biofuels to play a crucial role in reducing the carbon footprint of gas turbines and promoting greener energy technologies.
