“…Exergetic evaluation of H 2 FC buses have also been conducted [16]. Work on effects of light weighting has also been performed for automotive applications [17,18] as well as dealing with the challenges for modelling and integrating of light weighting into concept design [19]. However, there are no studies available on the effects of light weighting in relation to buses in general and H 2 FC buses in particular.…”

Hydrogen fuel cell (H 2 FC) buses operating in every day public transport services around Europe are assessed for their sustainability against environmental, economic and social criteria. As part of this assessment the buses are evaluated against diesel buses both in terms of sustainability and in terms of meeting real world requirements with respect to operational performance. The study concludes that H 2 FC buses meet operability and performance criteria and are sustainable environmentally when 'green' hydrogen is used. The economic sustainability of the buses, in terms of affordability, achieves parity with their fossil fuel equivalent by 2030 when the indirect costs to human health and climate change are included. Societal acceptance by those who worked with and used the buses supports the positive findings of earlier studies, although satisfactory operability and performance are shown to be essential to positive attitudes. Influential policy makers expressed positive sentiments only if 'green' hydrogen is used and the affordability issues can be addressed. No "show-stopper" is identified that would prevent future generations from using H 2 FC buses in public transport on a broad scale due to damage to the environment or to other factors that impinge on quality of life.

“…Automotive manufacturers have been adopting various technical strategies to address and comply with the legislation requirements. Among these technical strategies, aero-dynamical improvements, enhancement of powertrain efficiency, as well as the adoption of alternative propulsion systems and weight reduction continue to be investigated [5]. Research is focusing on the weight reduction of automobiles to address the pollution levels attributable to road transport.…”

“…Different researchers have demonstrated the feasibility of such a transition to lighter alloys, polymer composites and hybrid materials, even though some aspects of their environmental impacts have yet to be investigated [4,8]. Among the strategies that can be adopted to pursue the same scope, the most effective is the re-designing of vehicle parts, combined with material substitution [5].…”

The automotive sector has recently been taking measures to reduce fuel consumption and greenhouse gas emissions for the mobility of ground vehicles. Light-weighting, via material substitution, and the re-designing of components or even a combination of the two, have been identified as a crucial solution. Additive manufacturing (AM) can be used to technologically complement or even replace conventional manufacturing in several industrial fields. The enabling of complexity-for-free (re) designs is inherent in additive manufacturing. It is expected that certain benefits can be achieved from the adoption of re-design techniques, via AM, that rely on topological optimisation, e.g., a reduced use of resources in both the material production and use phases. However, the consequent higher specific energy consumption and the higher embodied impact of feedstock materials could result in unsustainable environmental costs. This paper investigates the case of the light-weighting of an automobile component to quantify the outcomes of the systematic integration of re-designing and material substitution. A bracket, originally cast in iron, has been manufactured by means of a powder bed-based AM technique in AlSi10Mg through an optimized topology. Both manufacturing routes have been evaluated through a comparative Life Cycle Assessment (LCA) within cradle-to-grave boundaries. A 69%-lightweighting has been achieved, and the carbon dioxide emissions and energy demands of both scenarios have been compared. Besides the use-phase-related savings in terms of both energy and carbon footprint due to the lightweighting, the results highlight the environmental trade-offs and prompt the consideration of such a manufacturing process as an integral part of sustainable product development.

“…On the other hand, any LCA study is highly influenced by the dataset used to develop the assessment (i.e. in this paper authors provided a study that involved a high number of components [25,26], materials and machining for a single product since its concept design [27,28]), IOP Publishing doi:10.1088/1757-899X/1275/1/012005 2 and it is not easy to manage a large set of data. To support the green design, the idea developed in this paper is to design and realize a simpler database that can be used as a gross dimensioning tool.…”

This paper presents a smart tool to support the determination of sustainability of automotive components. Many research and industrial activities have been concentrated in the field of sustainability of passenger vehicles through the development of smart materials, manufacturing technologies and production processes. However, the environmental impacts quantification phase is always the most difficult and challenging in the design process. Literature and technical regulations provide that the Life Cycle Assessment methodology needs a lot of resources (both human and economic resources) to be implemented because of its complexity. The base idea of this work is to design and realize a tool easy-to-use also by non-LCA experts, with a set of input and output GUIs (Graphical User Interfaces) to make the design process easier also from the point of view of impact characterization. As final result, the conceived method is targeted at representing a simple and ready-to-use tool, which allows the application of eco-design methodologies in the application to the automotive sector.
