Progress in hybrid and electric propulsion technologies for fishing vessels: an extensive review and prospects

In the highly competitive era of the maritime and fisheries sectors, the implementation of electric and hybrid propulsion systems in fishing vessels is becoming increasingly relevant. This study aims to review recent advancements in the application of electric or hybrid propulsion systems in fishing vessels. The method used to obtain publication references involved the use of VOSviewer, which functions as an additional tool for examining and displaying publication trends according to authors and keywords. The analysis shows that although some fishing vessels have adopted electric or hybrid propulsion systems, there is still a lack of understanding of the full benefits of this technology. According to recent studies, using environmentally conscious propulsion systems on fishing vessels has the potential to significantly reduce the release of greenhouse gases and improve operating efficiency. Therefore, future research is expected to fill this gap by exploring the potential application of state-of-the-art technology in the development of more efficient and sustainable fishing vessel propulsion systems. In this way, the fishing industry can make a greater contribution to achieving carbon neutrality and sustainability goals in the future.
