- Abstract
- The purpose of this study is to review existing and potentially applicable maritime renewable energy technologies which can be also commercially viable. Through literature review, hybrid research methodology and sorting of reviewed systems, a joint technologies’ concept has been developed. A brief technical study, separately on each element of the full concept, which consists of photovoltaic panels, wind turbines, piezo acoustic panels, a magnetic shaft generator and an energy storage system, being retrofitted on a Kamsarmax bulk carrier, has been conducted. Finally, a scenario-based environmental and economic analysis of the joint technologies concept, applied on the case study vessel trading between EU and US, along with deployment variations of the included components, has been carried out. The ten different comprised scenarios are the full concept application at maximum capacity, then independently, photovoltaic panels options at 100% and 50% hatch coverage panels, helical savonious wind turbines at collapsible and aerodynamic non-collapsible configurations, the piezoacoustic energy harvesting panels, the magnetic shaft generator under 3 operating modes and finally an optimum combination of the two most cost efficient technologies. The scenarios which included photovoltaics or magnetic shaft generators, resulted in considerable environmental benefit and commercially viable outcomes. A full concept’s application may reduce emissions up to 6.5% at open sea with optimum operation of all systems and up to 12.8% at port, solely from photovoltaics’ usage. Full concept’s required initial investment of approximately 8 million euros would require 12.5 years for amortization. The reviewed vertical axis wind turbines, without taking into account any possible aerodynamic deployment benefit, and piezoacoustic panels options are considered non-efficient due to very high installation costs, relatively low power production and non viable return of investment periods. On the contrary, even if independently installed, the solar panels and magnetic shaft generator options can provide viable return of investment periods between 9 and 16 years. The return of investment for the most efficient configuration, which consists of photovoltaic panels at full hatch coverage and the magnetic shaft generator under optimum usage, has been calculated at 10.5 years period, while providing up to 6.1% total average reduction of emissions and the flexibility of zero usage of vessel’s diesel generators, while at open sea. The existing renewable energy technologies can provide both actual environmental and economic benefits, though more bold steps within the shipping industry are necessary in order vessels being able to sail and operate more efficiently, environmentally wise.
