Project Summary
Expanding electric fleets require the energy infrastructure of zero-emission charging stations in ports. This project proposes a novel solution using a floating solar power plant combined with wireless charging technology for electric vessels, which is scalable and easy to use in various port locations. The project will deliver a lab prototype followed by a comprehensive design based on the Port of Dover, where the growing fleet of electrical vessels still lacks access to charging infrastructure. This will include site identification, solar harnessing and energy storage plan, vessel charging system and procedure, a logistic plan, and a cost-impact assessment.
Project Achievements
A systematic approach was applied from solar panel farm design to wireless charging points for vessels. Using PVGIS-SARAH2 satellite data, the System Advisor Model (SAM) simulated total energy generation, land usage, and component requirements such as PV panels and batteries. Economic analysis used data from previous projects in the USA and Canada, while environmental analysis compared CO2 emissions from combustion engines to electric vessels. A logistic plan for infrastructure development considers current technologies and future advancements. A small-scale 50W floating solar wireless power transfer system was designed, optimised through MATLAB and ANSYS simulations, and successfully tested experimentally.
Conclusions
This project proposed a floating solar farm with wireless charging points at the Port of Dover for vessels crossing between Dover and Calais, aligning with the green industry revolution to achieve net-zero emissions by 2050. It accelerates the decarbonisation of the port while providing social, economic, environmental, and societal benefits. Socially, it enhances energy independence, creates jobs, and develops skills. Economically, selling solar-generated energy boosts the port’s revenue, promoting sustainability. The automatic charging process improves staff safety, reducing electric shock risks. The project supports a low-carbon maritime system, advancing the transition to electric vessels, cutting emissions, and reducing reliance on fossil fuels. Finally, participation in the TRIG program provided expert guidance and networking opportunities, which led to potential collaborations and funding to scale up the wireless power transfer solution.
Next Steps
The project has enabled Cranfield University, the Port of Dover and other partners to submit a joint proposal to a national major research council (total project value 2 million GBP). The project has passed the proposal stage and is currently awaiting the interview and then a decision. If successful, a pilot site will be built in the real sea environment of the Port of Dover, exploring and testing the potential of floating solar power plants in the maritime decarbonisation trajectory. The next steps also include looking into other funding calls, and work with other stakeholders (ship operators, ports). Cranfield University is leading the co-innovation of the UK national maritime research hub, equipping us with a robust network to support further collaborations.
