This paper presents the concept and design of a tanker powered by, and carrying, liquid hydrogen (LH2). Beyond the realization of a complete reduction in carbon emissions, the concept is closely related to the authors’ proposal for a rethinking of ship operation with a substitution of Just-in-Time (JIT) by Warehouse-in-Transit (WIT). Ways to fund a LH2 tanker is also reviewed and suggested.

Long Distance Travel

Long-distance (LD) travel accounts for over 30% of person-trip miles, with important energy and emissions impact. LD business travel can often be replaced by remote participation, so targeting such trips for cost, time, and emissions savings may be a wise strategy for protection of the climate, budgets, and human health. To appreciate Americans’ LD travel choices better, a 73-question online survey was conducted in 2019 that captured 2,327 LD (over 100 mi each way) trips made by 929 respondents during the previous 12 months, of which 490 round trips were for business purposes. Predictive models for LD trips per adult per year, overnights, LD travel times, and willingness to participate remotely and/or purchase carbon offsets for those trips were developed using respondents in Austin only. As expected, those educated to degree level tend to travel more often, for both business and nonbusiness purposes; everything else is constant. People who undertake LD travel more frequently are more likely to spend less time in transit/en route. Single people or those from large households educated to degree level are more likely to be willing to pay for the carbon emissions produced by their flights. Out of the 298 LD business trips made by Austinites, remote participation is possible for approximately a quarter, and the respondents involved are willing to participate remotely in 44% of those trips. In other words, Austinites appeared willing to participate remotely in slightly over 10% of their business trips overall, at least before the COVID-19 pandemic. This is definitely not enough to address climate change concerns as a result of carbon emissions from LD travel.

Behavioural Aspects

Developments in digitisation and the need to reduce carbon emissions have increased attention on port call optimisation. Just-in-time arrival for ships is recognised in the literature as being achieved more readily in container trades than in bulk trades. This paper examines the governance and trade logistics conditions in the bulk trades of Vancouver, Canada, as the increasing number of ships at anchor gives rise to the need to explore the absence of initiatives to limit anchorage and to identify what is done elsewhere to manage the incidence of anchorage. Newcastle, Australia, is used to identify critical governance and logistics factors that played a role in the development of innovative practices to reduce anchorage. The major obstacles to port call optimisation lie in the organisational and behavioural aspects of maritime logistics, not in the technology of digitisation.

This chapter presents a decision support tool that can be used to evaluate the level of carbon emission and duration of delivery time for alternative distribution systems charged with just-in-time product delivery. An Excel-based transportation model is solved using linear programming to model transport truck carbon emissions and delivery time for a product landed at seaports in the United States and transported to meet customer demand at inland locations under stochastic demand conditions. The alternative network designs examined provide insights as to the viability of the optimal network design as determined by the transportation model. The model is illustrated using simulated demand scenarios and the robustness of the solution methodology is examined using a sensitivity analysis.

Significance Cost-control is no longer the overriding consideration, given regulatory and investor demands to address environmental, social and governance (ESG) concerns, and consumer demands for customisable and just-in-time goods and services. Linear supply chains are becoming reconfigurable value-adding networks where proximity to customers, suppliers and innovation ecosystems offer firms a competitive advantage.

This research design using survey method with data collection in cross-section through a questionnaire. The samples using simple random sampling with the number of respondents is 132 Managers in Manufacturing Company in Makassar Industrial Area. Data analysis method used in testing the hypothesis was Structural Equation Modeling (SEM). The results of the study provide evidence that just in time has no significant effect on the performance of the company. Supply chain management and competitive advantage have significant influence on the performance of the company. Supply chain management has significant influence on the competitive advantage. Competitive Advantage is a complete mediation in describing just in time for the performance of the company while in explaining the effect of supply chain management on the performance of the company, acting as a competitive advantage partial mediation. The practical implications of this research may provide an improved understanding of managers in improving company performance through competitive advantages influenced by supply chain management and just-in-time. Limitations of this study on a sample size of only using the manager just limiting the generalization the research finding. Originality of this study provide a basis for the development configuration modeling using SEM and conceptual models that prove the influence of supply chain management and just-in-time to the improvement of the performance of the company by entering a competitive advantage as mediation relationships between variables, which in previous studies carried out separately.
