“…For shipping, the fuel conversion options represented in the model are greatly based on a previous study that summarized pros and cons of different marine fuels ( Carvalho et al., 2021a ). While shipping fuel options are relatively diverse, the aviation sector is restricted to conventional kerosene and fully drop-in alternatives (therefore, options such as natural gas and hydrogen are not allowed to be used by aircrafts).…”

“…For simplicity, low-carbon fuels and renewable fuels are treated as synonyms over the text. They include conventional/advanced biofuels and renewable hydrogen-based fuels) ( Carvalho et al., 2021a ). This limitation refers to the whole set of potential mitigation measures that can help lower aviation and shipping energy intensities, including constructive and operational measures (e.g., improvements in hull and aircraft design, wind assistance, slow steaming, weather routing) ( Bouman et al., 2017 ).…”

“…Owing to these subsidies, such as tax reduction, RWG investors can get the opportunity to decrease establishment costs [16]. Carvalho et al [17] focused on the energy investments in Brazil. They reached a conclusion that for the effective management of the levelized energy costs, high establishment cost problem can be handled.…”

Energy costs are the key factors regarding the selection of appropriate renewable energy (RWG) alternatives. All costs of a power plant, such as investment, operation, maintenance, and repair are considered in the scope of levelized costs. Therefore, for the effective determination of the selling price of the energy, levelized cost has a guiding role. Because the levelized costs of RWG alternatives develop the sustainable production and energy consumption for the long term, the leading indicators of these costs should be analyzed significantly. Accordingly, in this study, it is aimed to investigate the levelized cost of RWG alternatives by using bipolar q-rung orthopair fuzzy (q-ROF) hybrid decision-making approach. The novelty of this study is to recommend an integrated decision-making model based on bipolar and q-ROFSs with golden cut. At the first stage, bipolar q-ROF multi stepwise weight assessment ratio analysis (M-SWARA) is employed for weighting the selected criteria of levelized costs of RWG alternatives. At the following stage, bipolar q-ROF technique for order preference by similarity to ideal solution (TOPSIS) is considered to rank the alternatives in terms of the levelized cost performance. On the other side, vise kriterijumska optimizacija i kompromisno resenje (VIKOR) model is also considered to rank the alternatives. In addition to this issue, the sensitivity analysis is also performed with four cases comparatively. Hence, consistency, reliability and coherency of the proposed model can be measured. It is identified that capacity loss has the greatest importance regarding the levelized cost of RWG projects. Solar is found as the best clean energy type with respect to the levelized cost management performance. In this context, it would be appropriate for investors to design projects close to the center. This will contribute to increasing the efficiency and productivity of these projects.

“…As such, low-carbon fuels are regarded as a key mitigation option for shipping 19 . Candidate alternative fuels are diverse both in terms of production routes and nal energy carriers 20 . Using some of them depends on implementing new motorisation options, such as dual-fuel engines and electrochemical powertrains.…”

In recent years, the decarbonisation of international shipping has become an important policy goal. While Integrated Assessment Models (IAMs) are often used to explore climate mitigation strategies, they typically provide little information on international shipping, which accounts for around 0.75 GtCO2/yr. Here, we perform the first multi-IAM analysis of international shipping, drawing on the results of six global models. Results indicate the need for decreasing emissions in the next decades, with reductions up to 88% in 2050. This is primarily achieved through the deployment of low-carbon fuels. Models that represent several potential low-carbon alternatives tend to show a deeper decarbonisation of international shipping, with drop-in biofuels, renewable alcohols and green ammonia standing out as the main substitutes of conventional maritime fuels.
