<p>The identification of alternative transport modes is urgently required as fuel price inflation is adversely affecting Samoa’s energy security and increasingly its economic and social well-being. The Samoan government has recognised the society-wide implications of fuel dependency and is moving towards improving fuel use efficiency of the national transport fleet and the identification of viable alternative transport fuels. This research analysed findings from global transport stakeholder organisations and modelled the energy consumption of electric vehicles (BEVs) under Samoan conditions. The results pointed to lower operating cost of BEVs which led to stakeholder support for the eCar pilot project aimed at establishing the feasibility of electro-mobility. The study adopted a postdevelopment approach as it provided information about BEV technology and invited Samoan transport stakeholders to contribute to mutual learning about alternative transport modes via a series of participative workshops. Postdevelopment thinking also pointed to assumptions made under prevailing conceptions of the modernist development project which may see the promotion of electro-mobility in the form of a commercial technology which is unaffordable to the majority of Samoans. The study concludes that in order to make electro-mobility accessible to a wider section of society, the concept of electro-mobility needs to be deconstructed into its components and rebuild to suit Samoa’s conception of modernity. This could literally mean BEV retrofit conversions of second hand cars to take advantage of the well documented energy efficiency of the electric motor and discounting the status enhancing ownership of a commercial BEV.</p>

AbstractRechargeable Li-based battery technologies utilising silicon, silicon-based, and Si-derivative anodes coupled with high-capacity/high-voltage insertion-type cathodes have reaped significant interest from both academic and industrial sectors. This stems from their practically achievable energy density, offering a new avenue towards the mass-market adoption of electric vehicles and renewable energy sources. Nevertheless, such high-energy systems are limited by their complex chemistry and intrinsic drawbacks. From this perspective, we present the progress, current status, prevailing challenges and mitigating strategies of Li-based battery systems comprising silicon-containing anodes and insertion-type cathodes. This is accompanied by an assessment of their potential to meet the targets for evolving volume- and weight-sensitive applications such as electro-mobility.

The problem of urban logistics operations in the context of their impact on the environment has become the key challenge. Due to that, there has been a growing interest in increasing the use of alternative fuels, including electro-mobility. However, an important barrier to the utilisation of electric freight vehicles (EFVs) is their travel range and battery capacity. The paper is focused on the idea of EFV utilisation improvement by implementation of charging stations in unloading bays. First, the Authors analysed the efficiency of chosen vehicles during daily work. Next, the potential improvement of their travel range was analysed, considering the short-time charging processes carried out during delivery operations, using the charging systems provided in unloading bays. Moreover, the concept of wireless chargers utilisation was proposed as a challenge for future work. According to the analysis, utilisation of unloading bays equipped with short-time battery chargers could improve significantly the travel range of EFVs. As a result, it could improve the efficiency of electric vehicles in last mile deliveries in city areas.

Electro-mobility (EV) is an emerging transportation method, whose charging infrastructure development concerns a key-factor for its growth. EV charging infrastructure has not grown yet in Greece, regardless of the ambitious national targets that have been grounded for 2030 towards a climate-neutral mobility. This study introduces a multi-criteria decision-making (MCDM) framework for EV charging infrastructure deployment and operation, which respects both the economic and the technical aspects for public charging stations. The analytic hierarchy process (AHP) was followed for the MCDM framework’s definition, which used criteria that were in the corresponding literature and performed with interviews by experts from the EV growing market in Greece. The results show that the installation and operation of public EV charging stations, located in private spaces to ensure their protection against vandalism, within the urban areas is the preferred deployment approach. Moreover, this article tests a market model for the EV charging infrastructure ownership and operation. Findings show that the incentive for investment in EV charging infrastructure market in Greece, is driven by the direct investments of limited vendors, while it is not economically oriented, but it focuses on sustainability and environmental protection.

This paper presents a novel evaluation framework to assess the effectiveness of city transformation projects related to energy efficiency and sustainable mobility actions. The evaluation framework is part of an Urban Regeneration Model designed to accelerate the urban transformation toward the smart city concept, taking into account all aspects of sustainability. This model has been developed and validated in the three EU cities (Valladolid, Spain; Nottingham, United Kingdom; and Tepebaşı, Turkey) where interventions in the energy, mobility, and ICT fields have been deployed. This model relies on an Evaluation Framework to support its main phases considering two levels of evaluation: city level, to assess globally the smartness and sustainability of the city, and project level, to support the decision-making and assess the impacts of specific implementations. This paper is focused on the second level and its application through the evaluation-supporting tool STILE in the assessment of the energy efficiency and sustainable urban mobility actions implemented in the city of Valladolid. The assessment analysis has allowed assessing how the energy efficiency interventions carried out in the Valladolid district have reduced the energy consumption, increased the use of renewable energies, and reduced the CO2 emissions. In addition, it has allowed evaluating other aspects such as the air quality, thermal comfort, and energy bill, which have been also improved for the residents. Considering the analysis of the sustainable mobility interventions, the evaluation framework supports the assessment of the reduction of emissions and air pollutants and how the actions have converted electro-mobility into a real option for citizens. The evaluation of results after the implementation of this kind of actions is key to ensuring that successful actions can be replicated in other places achieving smarter and more sustainable cities.

The development of electro-mobility is one of the centerpieces of European country attempts to reduce carbon emissions and increase the quality of life in cities. The goals of reducing emissions from the transport sector and phasing out fossil-fueled vehicles in (urban) transport by 2050 present unrivaled opportunities to foster electro-mobility. This paper provides a comprehensive review of the literature and provides a detailed analysis of the current development of electro-mobility in Europe, assessing social, economic, and environmental aspects under a circular economy (CE) context. It also examines the existing challenges and suggests ways of addressing them towards improving the environmental performance of electro-mobility and the urban quality of life. The paper argues that a narrow technology-only agenda in electro-mobility will be less successful without the imperative of the CE, including not just materials and resources but also energy, to unlock the medium-term co-benefits of de-carbonization of both the transport as well as the building and energy sectors. The paper critically reviews some of the anticipated future developments that may guide the growth of this rapidly growing field into a CE.
