“…is trend fits within the broader call in the maritime industry to reduce ocean shipping's carbon footprint [4]. In response to this call, maritime researchers have examined a range of alternatives, from the use of alternative fuels, to the setting of emission standards, speed optimization, and the use of shore power (e.g., see [5][6][7]).…”

“…ere are a number of interesting findings. First, compared to the single-well case, the 5-well rail car model can result in lower utilization since it introduces the additional constraint (7). For example, in instances 7 and 8 the utilizations are 0.75 and 0.94, respectively, which corresponds to a decrease of 6.25% and 2.08% compared with the single-well car model.…”

With the growth in global trade and its environmental footprint, sustainable modes of freight movement are increasingly important in today’s globalized world. This study focuses on on-dock rail, where the rail terminal is located within the marine container terminal. On-dock rail has in recent years become an essential mode of transportation to move containers out of congested marine container terminals. This study contributes to the literature by presenting tailored exact solution algorithms for a recently proposed optimization model to optimize the loading of double-stack trains. In particular, a 3-stage solution framework is presented for the case when rail cars have a single well. A complementary solution algorithm for the case when a rail car has multiple wells is also provided. Our results show that computational times can be drastically reduced, from 2+ hours to a matter of seconds, rendering the model suitable for practical use.

“…The efforts were made to understand the difficulties of implementation, evaluation system and operation method ( Innes and Monios, 2018 ) and control grid's disruption ( Sciberras et al, 2015 ; Radwan et al, 2019 ; Mao et al, 2020 ). Qi et al (2020) reviewed studies of shore power's economic challenges from the perspective of ship owners, port authorities, and governments. The basic cost models were summarized for different interested parties.…”

Carbon emission reduction of shore power from power energy structure in China

et al. 2022

With the construction of China’s ecological civilization and the proposal of carbon peaking and carbon neutrality goals, shore power has been vigorously developed as an important technology for the future green development of ports. However, China’s electricity is still mostly coal-fired, which produces many carbon emissions. Coupled with regional differences, shore power is by no means certain to lower carbon emissions compared with fuel throughout China. Considering the power energy structure in different regions, this paper establishes a carbon emission correlation model between fuel and shore power during ship berthing, calculates the feasibility and actual emission reduction effect of shore power in coastal ports, and studies the restriction condition of starting time for the use of shore power for ships attached to ports according to the national policy of mandatory use of shore power. The results show that only a small part of coastal provinces and cities are suitable for using shore power, and it is limited by the berthing time of the ship. However, this condition is not related to the size of ships but related to the proportion of power generation. Therefore, the government should develop shore power according to local conditions, and vigorously increase the proportion of clean energy, so that the shore power truly achieve zero carbon emissions.
