Biodiesel is an alternative fuel, has many benefits. It is biodegradable and non-toxic. Compared to petroleum based diesel, biodiesel has a more favourable combustion emission profile, such as low emissions of carbon monoxide, particulate matter and unburned hydrocarbons. These merits make biodiesel a good alternative fuel source to petroleum based fuel. Biodiesel feedstocks derived from microalgae and macroalgae have emerged as one of the most promising alternative sources alternative fuel because of lipid content, high photosynthetic efficiency to produce biomass and their higher growth rates and productivity compared to conventional crops. In addition to their fast reproduction, they are easier to cultivate than many other types of plants and can produce a higher yield of oil for biodiesel production. This study was undertaken to know the performance of seaweed as biofuel by comparing testing of B5 on engine test bed (CUMMINS NT 855-M Marine Diesel Engine) and mathematical estimation of energy yield from B5 and Seaweed. The performance test conducted for this study includes the speed, torque, Input Power, Brake Power, Break Specific Fuel Consumption and overall efficiency. https://www.biotech-asia.org/vol13no4/study-the-performance-of-biofuel-from-b5-and-laminaria-seaweed-on-engine-test-bed-for-marine-transportation/ Biodegradable; Biodiesel; B5; Emission; Performance
