“…Most papers rank ethanol fuels higher in comparison to other fuels [46,48] or consider them better suited for light vehicles [31,47,52,54,59,60], but less for buses or trucks [32,44]. Biodiesel, HVO and BTL [32,39,47,48,52,[54][55][56], as well as BEV, HEV and PiHV, score relatively well [23,29,32,34,35,39,46,47,55,56].…”

“…Further, our analysis provides evidence that evaluations with MCDA methods are highly dependent on the evaluation criteria (e.g., Maimoun et al [38] and Heo et al [12]) and weight settings (e.g., Aydın and Kahraman [44] and Vahdani et al [50]). Also the context in which the analysis is embedded, in particular the regional background (e.g., Iran in Sehatpour et al [31]) and the vehicle type assessed (e.g., light vehicles vs. buses), play a vital role. In this sense, variances in the results can often be traced back to specific factors and criteria going into the evaluation.…”

Multi-Criteria Decision Analysis (MCDA) methods help decision makers to consider and weigh diverse criteria that include economic, environmental, social and technological aspects. This characteristic makes them a popular tool to comparatively evaluate road transportation fuels and vehicles (RTFV). The aim of this paper is to systematically classify and analyse the literature applying MCDA methods on the evaluation of RTFV. To this end, 40 relevant papers are pinpointed and discussed. We identified a great number of evaluation criteria employed in the reviewed papers from which we have established a concluding list of 41 criteria, that can serve as a pool for future research. A further analysis of the evaluation criteria reveals that the process of criteria selection partly suffers from a lack of scientific foundation and standardization. We propose to standardize the criteria selection process by using the Life Cycle Sustainability Assessment (LCSA) methodology as a guiding reference. In addition, we compared the MCDA results obtained from studies with relatively similar setups and found that the evaluation results are also generally similar and seem not to be influenced by the particular MCDA method employed. Based on the results of the reviewed papers, one may say that electricity and ethanol appear to be good alternatives for light vehicles, whereas gaseous fuels seem more appropriate for heavy vehicles like buses. Striking deviations from these generally observed results are often caused by specific evaluation contexts, particular criteria taken into account and unusual weight sets applied.The last category (c) is concerned with hydrogen in particular, as is a potential energy carrier in the aforementioned fuel cell vehicles. Three specific hydrogen production paths are evaluated, i.e., electrolysis, steam reforming and gasification, sourced from different feedstock [11][12][13][14][15]. Multi-Criteria Decision Analysis MethodsThis Section shortly outlines the MCDA methods most often used in the reviewed papers. MCDA methods can be broadly divided in Multi-Attribute Decision Making (MADM) with limited solutions for a finite set of alternatives and Multi-Objective Decision Making (MODM) with indefinite solutions for an indefinite set of possible scenarios [16]. MODM methods usually comprise some form of optimization, for instance linear or nonlinear programming. These methods start with certain restrictions which determine the optimal solution [17] and find a solution by optimizing the resulting

“…According to Browne and Ryan (2011), MCA is increasingly used for environmental and transport decision-making, since it is better at dealing with the complexity of the issues involved, the need for a holistic view of environmental, economic and social impacts, and the fact that tools like CBA or EIA are inadequate for capturing the full range of impacts. Previous MCA studies on transportation have focused on aspects such as high-speed rail (Janic, 2003), electric city delivery vehicles (Wątróbski et al, 2017), alternative fuels for light vehicles (Sehatpour et al, 2017) and alternative fuels for long-haul freight transport (Osorio-Tejada et al, 2017).…”

The role of biogas in a more sustainable energy system in Sweden

There are numerous problems in the world that need to be dealt with in order to achieve sustainable development. The energy system has significant negative impacts on many of these problems, and there is a need for a transition towards more sustainable energy. Sweden has already started this transition and is using large amounts of renewable energy. However, within the transport sector and the manufacturing sector in particular, large amounts of fossil fuels are still used. Biogas is one alternative that can help solve several sustainability problems and that could be part of a future more sustainable energy system. However, it is not certain what biogas is most suitable to be used for. The aim of this thesis is to investigate how biogas should be used in a future more sustainable energy system, by answering three research questions: 1) In what ways can biogas be used in a more sustainable energy system? 2) How can we assess whether biogas is suitable in a specific context? and 3) What determines whether it is easy or difficult for a user to start using biogas? These questions are explored in a Swedish context using four appended articles, which are based on two collaborative projects using a combination of workshops, literature reviews and interviews. Biogas can be used for heat, electricity or fuel in the manufacturing or transport sector. In Sweden, heat and electricity are mainly of interest for smaller production scales, while production on larger scales will likely be dominated by upgrading mostly to CBG but also to LBG. CBG can be used for less energy-intensive purposes, such as cars or buses, while the growing interest in LBG in Sweden may open up new market segments for biogas which are more energy-intensive, such as heavy trucks or shipping, or in geographical locations that are further away from the site of production. Several sustainability assessment methods exist that can be used to evaluate whether biogas is suitable in a specific context, such as multi-criteria assessments or scenario analyses. These methods can include a number of different aspects that are relevant to biogas use, such as GHG emissions, safety issues, and the vitality of the surrounding region. In order to introduce biogas, six main factors were identified that can make this easier or more difficult: technical maturity, tank volume, distance between the producer and the user, scale of energy use, policies and costs, and strategies of individual organizations. Overall, the rise in LBG production creates new opportunities for biogas use in both geographical and usage areas that did not previously use biogas. There is no simple answer to what biogas should be used for in the futurerather, this depends on the circumstances. It is also possible that the usage areas that are most suitable now for biogas might not be the most suitable areas in the future, depending on developments within, for example, the electricity system and hydrogen. However, CBG and LBG are likely to dominate biogas production in Sweden until then.

Coal-water fuels have been actively studied in the last decade due to the fact that when they are burned in the furnaces of steam and hot-water boilers, much less anthropogenic oxides of sulfur, nitrogen, and carbon are formed in comparison with coal. The main problem that hinders the widespread introduction of such fuels in the energy sector is long (up to 30 seconds) ignition delay times. Significant (10%-50%) reduction in the ignition delay time is possi
