Abstract
The study analyzed the alternative energy sources for marine transportation in Nigeria. The aim of the study was to assess the relative importance of identified economic sub-criteria that influence ship operators’ preference of alternative energy sources for marine use, and to compare the scalability potentials of available alternative energy options for marine transportation in Nigeria, using identified scalability factors. The study used a survey method in which expert opinion of sampled population of ship-owners and operators on the comparative importance of the identified economic sub-criteria and the scalability factors was obtained. Questionnaire was used as the survey instrument, augmented with interview. The primary data generated from the survey was analyzed using the Analytical Hierarchical Process (AHP) tool, implemented by the use of an open AHP excel solver to determine the relative importance of the economic sub criteria of alternative energy options for marine transportation in Nigeria. The Analysis of variance (ANOVA) method was also used to compare the scalability scores of the alternative energy options. It was found that; LNG alternative energy option has maintenance cost with relative importance score of 0.63 as the most important economic concern and consideration by ship-owners for its full implementation for marine transportation in Nigeria. Electric drive and advanced bio-fuel (HVO) alternative energy options, has capital cost with respective relative importance scores of 0.39 and 0.41 as the most important economic concerns of ship owners and operators rather than energy cost and maintenance cost. Ammonia, hydrogen gas and methanol alternative energy sources, have energy cost with respective relative importance scores of 0.34, 0.41 and 0.79 as the most important economic consideration by ship owners and operators in Nigeria. The result also indicates that based on the three scalability sub-criteria, LNG has a scalability ranking of 1 and highest mean scalability score. As a result, LNG is the alternative energy source with the most scalability potentials and maturity for implementation for marine use in Nigeria. This is seconded by electric drive with a maturity for scalability ranking of 2.
