Abstract
This white paper aims to provide a strategic and technical overview of OTEC, highlighting its potential, challenges, and pathways for large-scale deployment. Building on the 2024 White Paper OTEC, which provided a broad analysis of economic considerations, scalability challenges, key components, and mitigation strategies, this document goes deeper into the specific requirements for commercial implementation. Given the unique energy needs of Small Island Developing States (SIDS) and tropical coastal regions, it serves as a practical guide for decision-makers looking to integrate OTEC into national and regional energy strategies.
The document outlines the role of OTEC as a stable, baseload renewable energy source, highlighting its multifunctional applications. It evaluates environmental and social considerations, addressing marine ecosystem impacts and community engagement strategies to ensure responsible deployment. Additionally, it identifies key economic, policy, and regulatory barriers, emphasizing the need for financial mechanisms, workforce development, and supportive policy frameworks. It also explores technological advancements and deployment strategies, leveraging lessons from offshore wind, and assessing scalability through existing industrial supply chains. Finally, it provides strategic recommendations for OTEC’s global expansion.
