“…This trend is expected. as biodiesel has a lower energy content (Table 1) than fossil diesel [49,50]. Figure 2 shows a clear comparison between the two biodiesels, where soybean-based biodiesel has a better power output than waste oil biodiesel.…”

The study investigated the engine performance and emission using biodiesel from soybean oil and waste cooking oil. The fuel properties of these biodiesels were determined using ASTM D6751and EN 14214 standards. The fuels were tested in a multi-cylinder diesel engine with an electromagnetic dynamometer and a 5-gas analyser was used for emission analysis. The result shows that the thermal performance of the engine slightly decreases with increase of the biodiesel blends ratio (i.e. B5, B10, B15, B20 and B50). On the other hand, emission decreases with the increase of biodiesel blends. The reduction in emissions was different for both biodiesels. Waste oil biodiesel showed better trends of emissions reduction with increase of the biodiesel percentage compared with soybean biodiesel. The brake specific fuel consumption (BSFC) of both biodiesels is (6.05%, 9.13%, 12.36% and 18.57% for soybean) and (8.17%, 11.40%, 17.71% and 14.96% for waste cooking oil) higher than diesel, respectively. However, soybean biodiesel consumed less fuel and produced more power and torque compared to waste oil biodiesel. The study concluded that B10 soybean biodiesel blend produced more consistent and expected results than waste oil biodiesel from the performance and emission point of view.

“…Similarly, electricity produced with fossil fuels cannot be considered a renewable fuel, but in this paper Swedish, fossil-free electricity production is assumed. Mohseni et al (2013) e Basha et al (2008) and Marchetti (2012) f Wetterlund et al (2011) and Harvey (2011) g EC (2011a) Aside from the difference in fuels, the transport system is assumed to be equivalent in both scenarios. The scenarios have the same predicted transport demand and vehicle fleet composition, as presented in Table 4.…”

Bridging the implementation gap: Combining backcasting and policy analysis to study renewable energy in urban road transport

et al. 2015

This paper combines backcasting and policy analysis to identify the opportunities for and barriers to the increased use of renewable energy and energy-efficient vehicles in an urban road transport system, namely, that of Stockholm, Sweden, in 2030. The combination of methods could bridge the implementation gap between scenario-based research and actual policy implementation and thus increase the chances of research being implemented in practice. In the case study, backcasting identifies a need for diverse fuels and vehicles and for immediate policy action. However, analysis of policy integration demonstrates that such action is unlikely given current policy structures. The fundamental lack of integration between energy and transport policy obstructs measures to increase the use of renewable fuels and more energy-efficient vehicles, which in turn obstructs the reduction of CO2 emissions from transport. The combination of backcasting and policy analysis is demonstrated to improve our understanding of the prerequisites for transitioning to a system based on renewable energy, and could thus be useful in further research.

“…In addition, studies on the economical feasibility and environmental impact are also required. Indeed, the complete fuel properties need examining along with engine testing for the biofuel product for the high-temperature approach (Basha et al, 2009). On the other hand, the fine studies on the reactions pathways and/or chemical kinetics are also attractive works to better understand the high-temperature approach.…”
