Harnessing the Potential of Napier Grass (Pennisetum purpureum) for Sustainable Biofuel Production
Year: 2025
Type: article
Abstract: Napier grass (Pennisetum purpureum) is an energy-rich C4 perennial grass that has potential as a biofuel feedstock for sustainable growth. It originally comes from Africa but can cultivated in tropical and subtropical regions, producing 25–35 oven-dry tons per hectare per annum, much greater than other energy grasses. Its low-input growth requirements, weeding capacity, and intercropping system compatibility render it yet more desirable as a renewable power source. Napier grass is most useful to produce biofuel since it yields bioethanol and biogas with minimal interference in the food supply. Its cellular content, with high carbohydrate and lignocellulosic compound contents, provides effective biochemical conversion with minimum wastage. In addition, the grass shows resistance against drought, allowing it to grow well in water-scarce regions. This review examines the botanical traits, growth requirements, and biofuel production capacity of Napier grass, noting its strengths and potential in renewable energy projects. By overcoming challenges like genetic variability, disease tolerance, and water efficiency, Napier grass can be central to the shift toward sustainable bioenergy systems.
