Abstract

The maritime industry is under increasing pressure to decarbonise, presenting an important pathway of transforming the power systems from conventional marine fuels to electric-based. This study proposes an innovative solution to support maritime decarbonisation through the integration of a floating solar clean energy harnessing and wireless power transfer (WPT) technology for electric vessels. The paper presents the design and experimental tests of the integrated system specifically, based on a model of an electric yacht. This study provides an in-depth analysis of application of floating solar to provides an off-grid wireless power transfer system that can scale for larger vessels such as ferries. The off-grid modularity proposed enables scalable, flexible, and sustainable energy delivery for maritime applications and decarbonisation with specific attention to challenges in WPT alignment and environmental condition. Simulations using ANSYS Maxwell were performed to model the magnetic field interactions and ascertain the optimal power transfer efficiency. Subsequently, a reduced-scale prototype system was designed, built and tested in a wave tank. The experimental results demonstrated efficient wireless charging with an average efficiency of 82 %, and the docking system proved effective in maintaining alignment even when the ship has wave-induced motions. The findings support the feasibility of using floating solar WPT systems for maritime vessels and pave the way to larger-scale studies.

电动船舶用浮动太阳能无线传输系统:设计和实验室试验
海运业面临着越来越大的脱碳压力,这是将电力系统从传统船用燃料转变为电力系统的重要途径。本研究提出了一种创新的解决方案,通过集成浮动太阳能清洁能源利用和电动船舶无线电力传输(WPT)技术来支持海上脱碳。本文以某型电动游艇为例,详细介绍了该综合系统的设计和实验测试。本研究对浮动太阳能的应用进行了深入分析,以提供一种离网无线电力传输系统,可以扩展到渡轮等大型船舶。提出的离网模块化为海事应用和脱碳提供了可扩展、灵活和可持续的能源输送,特别关注WPT对齐和环境条件方面的挑战。利用ANSYS Maxwell进行了磁场相互作用的仿真,确定了最优的功率传输效率。随后,设计、建造了一个缩小尺寸的原型系统,并在波浪槽中进行了测试。实验结果证明了无线充电的效率,平均效率为82%,并且对接系统被证明即使在船舶有波浪引起的运动时也能有效地保持对准。这些发现支持了在海上船只上使用浮动太阳能WPT系统的可行性,并为更大规模的研究铺平了道路。
