The technical and economic potential of renewables in Indonesia and scenarios for power system decarbonisation

Indonesia has been dependent on its abundant coal reserves to meet its increasing electricity demand. The Indonesian government is aware of the negative environmental effects of coal combustion and pledged to become carbon neutral by 2060 or earlier by transitioning towards renewables. In principle, it is known that Indonesia has large renewable...

Geospatial analysis of Indonesia's bankable utility-scale solar PV potential using elements of project finance

Geospatial analysis is useful for mapping the potential of renewables like solar PV. However, recent studies do not address PV’s bankable potential for which project financing can be secured. This paper proposes a framework that incorporates project finance into geospatial analyses to obtain the bankable potential of renewables. We demonstrate...

The global techno-economic potential of floating, closed-cycle ocean thermal energy conversion

Ocean Thermal Energy Conversion (OTEC) is an emerging renewable energy technology using the ocean’s heat to produce electricity. Given its early development stage, OTEC’s economics are still uncertain and there is no global assessment of its economic potential, yet. Here, we present the model pyOTEC that designs OTEC plants for best economic...

Is bigger always better? Designing economically feasible ocean thermal energy conversion systems using spatiotemporal resource data

Ocean Thermal Energy Conversion (OTEC) produces electricity using the temperature difference between warm surface and cold deep-sea water. OTEC systems in literature only limitedly consider seasonal seawater temperature<br/>variations and thus might not be adequately sized for off-design conditions. This potentially leads to techno-economically...

Plant siting and economic potential of ocean thermal energy conversion in Indonesia a novel GIS-based methodology

Indonesia strives for a renewable energy share of 23% by 2025. One option to contribute to this goal is Ocean Thermal Energy Conversion (OTEC). Despite a global theoretical potential of up to 30 TW, its economically deployable share remains unknown. This paper proposes a novel methodology, which enables to determine OTEC's economic potential...

Recent progress in the economics of ocean thermal energy conversion: Critical review and research agenda

Ocean thermal energy conversion (OTEC) is a Renewable Energy Technology (RET) with a global theoretical potential of up to 30 TW. However, OTEC's economic potential is unknown as it is still an immature technology with no commercial plant operating. This paper reviews recent academic and industrial literature since 2005 to provide an overview...

National and Global Projection of the Economic Potential of Ocean Thermal Energy Conversion and Development of Implementation Scenarios

Ocean Thermal Energy Conversion (OTEC) is a renewable energy technology which could help tropical countries worldwide in their shift from conventional to sustainable energy systems. But despite a practicable global potential of 4.4 TW as well as benefits like continuous operation and wide-ranged scalability, OTEC's contribution to the energy...
