Upscaling scenarios for ocean thermal energy conversion with technological learning in Indonesia and their global relevance

Ocean Thermal Energy Conversion (OTEC) is a promising renewable energy technology that the most economical at large scale. But contemporary literature does not address how OTEC could reach such scale with current technology, and what techno-economic impact of location-dependent factors technological learning are. This paper tackles these issues by simulating OTEC's upscaling model implements to meet local electricity demand extrapolates global relevance OTEC. The uses rate for investment costs cost finance. study shows up 45 GW capacity can be installed in Indonesia national coverage 22% 2050. Even small reduction rates, profitable cost-competitive against other power generation technologies an aggregated Net Present Value (NPV) US$ 23 billion. funded via state budget reallocation or international financial institutions, e.g. feed-in tariff suggested paper. However, large-scale only feasible regions high until size reached, must coordinated globally, proposed strategy. To contribute transition, needs grow 28% per year, similar wind solar PV. provides good reasons fight attention decision makers future research focus on refining concepts this study.
