Experimental development of biodiesel fuel derived from freshwater microalgae for improved engine performance and reduced emissions

Year: 2024

Type: article

Abstract: This study is conducted to research the production of biodiesel from Chlorella vulgaris microalgae and its feasibility as a renewable, low-emission alternative to fossil diesel fuel. Test results of the biodiesel in a single-cylinder diesel engine show a 60 % decrease in CO₂ emissions and a 20 % reduction in NOx emissions at various operating loads and speeds. It also yielded consistent results in terms of engine efficiency, with only slight power trade-offs at high-load scenarios—an indication that this biodiesel is compatible with conventional diesel engines. Further, by GC-MS detailed analysis for validation of the chemical composition and purity of the biodiesel, it indeed contained major fatty acid methyl esters, including methyl oleate, methyl linoleate, methyl palmitate, and methyl stearate. These results affirm the conformity of biodiesel to the requirements of industry standards and support its feasibility as a clean, renewable fuel. This study contributes to the dual environmental and performance benefits of microalgal biodiesel and underlines its place in sustainable energy systems and carbon footprint reduction.
