Bio diesel as an alternative fuel for maritime transport
(Indian Maritime University, 2011-09-30) Misra, S. C.; Ramesh, U. S.
Movement of goods through seaways and rivers is one of the most energy efficient modes of transportation. Majority of the ships and boats in maritime transportation use Diesel engines for propulsion and power requirements burning a variety of grades of fossil fuel. However with the advent of the concept of sustainable environment, this industry is also looking towards improving its energy efficiently and environment friendliness. This paper outlines the regulatory requirements for fuels and emissions from diesel engines from ships operating in international trade. While Bio Diesel is one of the alternatives for reduction of maritime emissions due to its very low or negligible sulphur content and amenability to complete combustion, its testing in a marine environment in India is limited. The paper gives an overview of some of the results of studies conducted internationally on the use of Bio Diesels in marine transportation. An estimate of requirement of biodiesel for Coastal shipping in India is presented. The paper stresses the need for increased testing of Biodiesel blends in marine engines to quantify the benefits and cost implications for use in coastal and river movement of cargo and passengers.
