Systematic Overview of Newly Available Technologies in the Green Maritime Sector

The application of newly available technologies in the green maritime sector is difficult due to conflicting requirements and inter-relation different ecological, technological economical parameters. governments incentivize radical reductions harmful emissions as an overall priority. If politics do not change, continuous implementation stricter government regulations for reducing will eventually result mandatory use of, what we currently consider, alternative fuels. Immediate radically strategies would significantly increase economic costs transport, thus jeopardizing its greatest benefit: transport massive quantities freight at lowest cost. Increased immediately disrupt global economy, seen recently during COVID-19 pandemic. For this reason, industry has shifted towards a gradual decrease through “better” transitional solutions until fuels become low-cost Since topic very broad interdisciplinary, our systematic overview gives insight into state-of-the-art with focus on following subjects: (i) fuels; (ii) hybrid propulsion systems hydrogen technologies; (iii) benefits digitalization aimed increasing vessel efficiency; (iv) hull drag reduction (v) carbon capture technologies. This paper outlines challenges, advantages disadvantages their implementation. results analysis elucidate current technologies’ readiness levels expected development over coming years.
