Advancing Marine Renewable Energy for Island Nations: Design and Development of a 20 kW Floating Kuroshio Turbine (FKT)

Received: 15 September 2025;  Published: 10 December 2025;  doi: 10.21926/jept.2504017

Abstract

Taiwan relies heavily on imported fossil fuels, with over 98% of its energy demand supplied by foreign sources, posing significant challenges to national energy security. To explore alternatives, this study investigates the potential of marine renewable energy by developing a 20 kW floating hydrokinetic turbine prototype designed for deployment in the Kuroshio Current. The research encompasses system design, model validation, and both tank and at-sea testing to evaluate hydrodynamic performance [...]

Framework for the Secured Integration of Renewable Energy into Power Systems

Received: 11 June 2025;  Published: 05 December 2025;  doi: 10.21926/jept.2504016

Abstract

This research introduces a blockchain framework to improve security and transparency for the use of renewable energy in power systems. The framework utilizes a permissioned blockchain architecture and IoT-based real-time monitoring to ensure data integrity and confidentiality and support efficient peer-to-peer (P2P) energy trading. Compared with traditional centralized energy management systems, the proposed design increases transaction security by 35%, decreases verification wait times by 28%, [...]

BESS Sizing Optimization Combined with Optimal Scheduling Method Considering the Battery Degradation Using PSO

Received: 17 June 2025;  Published: 24 October 2025;  doi: 10.21926/jept.2504015

Abstract

Recently, renewable energy projects using storage systems have gained significant attention. This innovative technology requires a comprehensive investigation to overcome the technical and economic issues, which are related to optimal storage system capacity and operational requirements. In this study, an extensive battery energy storage system (BESS) sizing method was proposed considering four variables: charging and discharging scheduling, state of charge, BESS rate energy and power capacity, [...]

Bridging Togo’s Energy Gap: Renewable Energy Potentials, Policy Challenges, and Strategic Pathways for Sustainable Development

Received: 22 December 2024;  Published: 13 October 2025;  doi: 10.21926/jept.2504014

Abstract

This work investigates the potential of renewable energy to significantly reduce Togo’s energy deficit, offering a critical analysis of the country’s current energy landscape. It evaluates the availability and viability of renewable energy sources—particularly solar and small-scale hydropower—and examines the mismatch between energy supply and growing demand. The study highlights Togo’s heavy reliance on biomass and energy imports from neighbouring countries such as Ghana, Côte d’Ivoire, and Nig [...]
