Potential of Renewable Energy in Jamaica’s Power Sector: Feasibility Analysis of Biogas Production for Electricity Generation

Abstract

Jamaica is heavily dependent on fossil fuels to meet its energy demand and is currently seeking to reduce consumption. Accordingly, it is essential to investigate the expansion of renewable energy systems to achieve its 2030 renewable energy goal of 50%, with 70% diversification in energy types, as outlined in the National Energy Policy 2009–2030. This study explores biogas feasibility in Jamaica and discusses the potential for electricity generation from combinations of dairy cow and Swine feces with sugarcane bagasse. The study’s primary purpose is to assess the feasibility of biogas production from livestock manure and sugarcane bagasse for electricity generation and manure treatment. Findings reveal that biogas anaerobic digestion and the co-digestion of different varieties of animal manure with sugarcane bagasse can generate up to 122,607.68 MWh or 2.49% of Jamaica’s total electrical energy generation in 2019. The findings indicate a high potential for the installation of community-based plants. Moreover, considering all scenarios and the remaining feedstock, potential electrical energy increases to 222,868.60 MWh (4.53% of total energy generation). This power may be fed to the electrical grid network or consumed by local producers. In addition, electric power generation from animal manure and sugarcane bagasse is feasible with improved technical capability and human development. Additionally, anaerobic digestion and co-digestion of sugarcane bagasse plus animal manure offer an excellent solution to mitigate climate change.
