Design of a Combined Offshore Renewable Energy System for Bonny Nigeria based on Comparative Feasibility Analysis

Nkemjika Mirian Asiegbu

Abstract


The design and feasibility analysis of a combined offshore renewable energy system for Bonny coastal area in Nigeria have been conducted. Statistical parameters obtained from resource assessments of ocean tidal current/range, offshore wind and wave energy sources were used to determine the configuration of the conversion technologies adopted. Then, the combined system integrated with pumped hydro storage was designed using the result of the obtainable resource for the location. Simulations were carried out using MATLAB codes to optimize the system. Results identified tidal energy as the most economical offshore renewable energy source at the location. Offshore wind velocities were higher than land wind velocities when compared with other research findings for the region. The average wind velocities at the offshore location were 3.9 m/s and 5.1 m/s at elevations of 10 m and 100 m above sea levels. The offshore renewable energy climate at Bonny compared well with locations in other countries where pilot or full-scale power generating systems already exist. The present designed system can provide a stable 187 [MW] mean daily power at a unit cost of 0.226 [$/kWh] using a project life span of 25 [years]. The system configuration utilizes 10% wind, 10% wave, 25% tidal range and 55% tidal current energy sources. Lower interest rates and little or no inflation made the system more feasible. These findings contribute to preliminary database of offshore renewable energy resource assessments intended to attract government funding, incentives and subsidies to drive research and development in offshore renewable energy utilization in Nigeria.
