Abstract [en]

This paper presents a case study covering the operational and functional performances of the Bus Rapid Transit (BRT), Light Rail Transit (LRT), and Monorail (MNT) modes in the Sao Paulo City, Brazil. The innovative multicriteria decision aid model (MCDAM) combine the use of a Functional Unit with the Analytic Hierarchy Process (AHP) method to access objective and subjective preferences of stakeholders and performances of alternatives of three transport options. The case study shows that the MCDAM has proven to be the most effective. The Functional Unit provided a common set of requirements to guide the performance assessment of the modal options. In addition, the evaluated stakeholders' preferences were combined with the performance assessment resulting into global priority indexes based on a linear additive function algorithm.

Abstract [en]

Organic waste to energy (OWtE) technologies have been already developed and implemented in Latin America and the Caribbean (LAC) countries, but are still far away to significantly contribute not only to manage and treat the ever-increasing waste volumes in the region but also to supply its energy demand and meet national GHG reduction goals. The technical complexity of these technologies, dearth of research, high investment costs and political deficiencies have not allowed for an appropriate implementation of relevant OWtE in the region, where the applicability of large-scale treatment plants remains to be demonstrated. This research presents the state-of-the art of OWtE technologies in the context of LAC countries’ based on archival research method. The main findings show that OWtE have the potential to improve waste management and energy systems in the region by reducing environmental impacts, along with a series of social and economic benefits, such as increasing sustainable energy supply. However, there is still a lack of investment and participation of stakeholders aligned with other challenges, which inhibit the implementation and diffusion of OWtE in LAC.

Abstract [en]

In Brazil, there are almost ten million people relying on traditional use of biomass for cooking, which correspond to about five percent of the country's population. The vast majority lives in poor municipalities away from urban centers. The replacement of fuelwood for LPG is the result of an intense urbanization process and governmental intervention based on price regulation and subsidies. In 2015, the energy demand for cooking in the Brazilian households was 46 TJ, LPG covered 51% of the demand and the remaining 49% relied on fuelwood to supply the demand for energy. This study shows that there are enormous variations in the level of consumption and the types of fuels used due to the regional complexity of Brazil. In addition, it also shows the transition from fuelwood for cooking to modern fuels such as LPG does follow a consistent pattern in Brazil. Decisions related to energy consumption and fuel type are strongly influenced by accessibility, affordability and the convenience of the fuel.

Abstract [en]

In this study, practical biogas potential has been estimated in order to clarify the role of biogas in policy targets for renewable transport fuels in Sweden. The estimate of the Stockholm County biogas potential is based on a survey directed at key persons at sewage water treatment facilities, as well as official statistics, environmental reports and other sources. The results reveal that the practical biogas potential can meet the vehicle gas demand in Stockholm County by 2020, but that it may cover only 50 % of the demand by 2030. The practical potential is estimated to be 604 GWh by 2020 and 689 GWh by 2030. Fossil gas, biogas from neighboring regions, and/or methane from woody biomass would thus be needed to meet the demand by 2030. The survey shows that digestion capacity exists at sewage water treatment facilities and that the availability of resources for biogas generation is low. Public participation is needed to improve food waste segregation and increase resource availability. Food waste can be co-digested with sewage sludge at sewage water treatment facilities. These results can guide the design of renewable transport fuel policies and one conclusion is that policy support should be directed at the supply rather than at the demand side.

Abstract [en]

The objective of this study is to verify whether natural gas is only a backup fuel against shortages of upgraded biogas or a threat to the Swedish vision of pursuing a vehicle fleet independent of fossil fuels. The paper uses Stockholm County as a case study to guide our analysis. The region not only concentrates the largest number of inhabitants in Sweden but also holds alone around 35% of the Swedish fleet of passenger cars using gas as fuel. The region's potential vehicle gas demands are 460 GWh by 2020 and 1202 GWh by 2030. The methodological approach relies on Network Theory to guide the numerical analysis of the vehicle gas supply chain in the region. Our results show that natural gas will keep on being an important resource and playing a vital role within the local vehicle gas supply chain but no longer as a backup fuel against upgraded biogas shortages. In fact, natural gas has become a price regulator responsible for vehicle gas attractiveness, especially for passenger cars in the region. As a result, phasing out natural gas could hamper future developments of biogas supply chain in the country, hindering the achievement of a green fleet.

The region’s potential vehicle gas demands are 460 GWh by 2020 and 1 202 GWh by 2030. The methodological approach relies on Network Theory to guide the numerical analysis of the vehicle gas supply chain in the region. Our results indicates that local vehicle gas supply chain is a rigid structure that might be averse to new entrants such as new distribution companies but, at the same time, it offers opportunities for biogas producers. Distribution companies, especially those placed in the 1st-tier segment are averse to new entrants because they present high homophily and strong ties. Hence, they are more prone to maintain the network’s status quo since the Swedish vehicle gas market is not yet well developed, which results in a lack of multiple players, which leads to cluster formation.

Abstract [en]

The use of biofuels for road transport in Sweden has increased during the past 10. years as policymakers stimulate demand in response to concerns about climate change. Using a supply chain approach, this paper analyses: (i) existing biofuel supply chains in Sweden (biogas, biodiesel and bioethanol) in terms of security of supply, and (ii) possibilities to achieve synergies between implementation of climate change mitigation practices and security of supply objectives, through increased production and use of biofuels. We argue that synergies can arise when exposure to upstream market risk decreases, the risk of the feedstock does not correlate with the fuel that it replaces, producers can switch between feedstocks and end user vulnerability to disruptions decreases. In the current Swedish context, the features of the biogas supply chain make it the most beneficial option, followed by biodiesel. In the way it has been implemented, bioethanol is the least favourable option. The paper concludes by outlining how biofuels could contribute to security of supply in the future.

Abstract [en]

The objective of this study is to present an analytical framework monitoring the development of the Swedish biofuels system, to evaluate its impacts on the achievement of 10% of renewable fuels by 2020, and to identify development patterns in order to establish a vehicle fleet independent of fossil fuels by 2030. The methodological approach relies on systems thinking approach and uses causal loops diagram as a guide to our analysis. The results show that policymakers have to decide among different pathways of growth based on internal- and external-resources of the Swedish biofuel system as well as to apply either supply or demand pressures onto the system in order to accomplish a vehicle fleet independent of fossil fuels by 2030.

Abstract [en]

This paper verifies the plausibility of existing assessments of the biogas potential in Sweden and whether a target of 1.1 TWh of biogas for transport, as per defined by Swedish authorities, can be met within the next ten years. We estimate that the Swedish resource potential for biogas generation from residues and energy crops amounts to 8.86 TWh in the midterm, equivalent to around 9% of the current domestic transport energy consumption. A large share of this potential remains unrealized and there is uncertainty regarding the existing resource potential, especially concerning energy crops. Nevertheless, the remaining biogas potential can make an important contribution to meet targets of an increased share of renewables in transport.  The study concludes that not only it is possible to meet the increased demand expected for gas in transport until 2020 but the existing potential could justify more ambitious goals than presently set by Swedish authorities.
