Analysis of Ocean Renewable Energy (ORE) Research and Application in West African Region – A case study of Liberia

upervisor: Prof. Alan Lewis Abstract The global transition towards renewable energy has underscored the significance of ocean  renewable energy (ORE) as a sustainable and viable alternative to fossil fuels. Liberia, with  its extensive coastline along the Atlantic Ocean, possesses untapped potential for various  ORE technologies, including tidal, Ocean Thermal Energy Conversion (OTEC), saline grid  conversion, wave, and wind energy. However, the absence of empirical research on the  feasibility, structural implications, and economic impact of these technologies in the  Liberian context poses a critical gap in energy planning and policy formulation. This study  aims to bridge that gap by evaluating the viability of ORE in Liberia through a  multidisciplinary approach that integrates geospatial analysis, economic modeling, and  stakeholder consultations. The research employs a mixed-method approach, combining qualitative and quantitative  data collection techniques to assess the structural and economic impact of ORE adoption in  Liberia. Primary data sources include field measurements, stakeholder interviews, and  surveys, while secondary data is drawn from existing literature, government reports, and  global case studies. Key analytical tools include statistical modeling, cost-benefit analysis,  and geospatial mapping of potential ORE sites along the Liberian coastline. Ethical  considerations are incorporated to ensure responsible data collection and stakeholder  engagement. Findings from the study indicate that Liberia has significant potential for ORE development,  with wave and wind energy demonstrating the highest feasibility in terms of structural  sustainability and energy output. Economic analysis reveals that initial capital investments  in ORE infrastructure can be offset by long-term energy cost savings and reduced  dependency on imported fossil fuels. Additionally, ORE development is projected to create  employment opportunities, stimulate local economies, and contribute to climate change  mitigation efforts. However, several challenges, including policy gaps, technological  limitations, and financial constraints, must be addressed to facilitate large-scale ORE  deployment. This research contributes to the growing body of knowledge on ORE in West Africa by  providing an evidence-based framework for assessing renewable energy potential in  coastal regions. The study's recommendations emphasize the need for policy incentives,  public-private partnerships, and international collaboration to accelerate ORE adoption in  Liberia. Future research should focus on long-term environmental monitoring, pilot  projects, and hybrid renewable energy integration to enhance the reliability and efficiency  of ORE systems. Through strategic investment and regulatory support, ORE can play a  transformative role in Liberia’s energy security and sustainable development agenda.
