- PostA 3D-model for O2 airglow perturbations induced by gravity waves in the upper mesosphere(2017) Li, Anqi; Chalmers tekniska högskola / Institutionen för rymd- och geovetenskap; Chalmers University of Technology / Department of Earth and Space SciencesTo investigate the influence of atmospheric waves in the mesosphere, a new Swedish satellite MATS (Mesospheric Airglow/Aerosol Tomography and Spectroscopy) will be launched in 2019. It will observe infrared emissions at 762 nm from the O2(b1+ g ) airglow in the region of 70 - 110 km altitude. As a part of the design work for the MATS project, an accurate forward model is needed to estimate what MATS is expected to measure. The results from this model will be used to evaluate the retrieval methods for processing the measurements from MATS. In this thesis project, a gravity wave model and a photochemistry model were coupled to simulate both the day- and nightglow emission fields in three spatial dimensions and time. Simulated satellite images were generated taking into consideration the sphericity of the Earth and the limb-viewing geometry of MATS. Simulation parameters were set according to the preliminary design of the instrument, such as the satellite orbit, image resolution and spectral selections. These satellite images were the first simulated airglow limb images made for the MATS project. By analysing the output data, the relations between wave parameters and airglow perturbations were investigated. It was shown that wave patterns can be easily observed between 85 - 105 km due to the relatively large perturbation in airglow emissions. The O2 airglow emission field was found to be highly sensitive to atomic oxygen concentration field as an input. Furthermore, as expected, wave patterns projected on simulated satellite images largely depend on the horizontal orientation of the wave propagation. This implies that a tomographic reconstruction is needed when the angle between the wave front and the limb-viewing direction is large. Finally, limitations of the model were discussed.
- PostA Carbon Footprint Assessment on Construction and Maintenance Operations for the Port of Gothenburg - With emphasis on emission reduction actions(2014) Sarbring, Anna; Chalmers tekniska högskola / Institutionen för energi och miljö; Chalmers University of Technology / Department of Energy and EnvironmentPorts are an industry that emits high levels of CO2 missions. The purpose of this thesis is to minimise CO2-eq emissions from the Port of Gothenburg. Four main objectives are used to achieve this purpose. The first is mapping ports, with respect to CO2-eq emission related activities and reduction targets. Four ports are selected in this report, located in Antwerp, Gothenburg, Los Angeles and Valencia to determine different emission reduction actions. Such actions are a combination of technical development, using same equipment but more efficiently or by change of behaviour. Since no ports have estimated CO2-eq emissions from construction and maintenance operations before, this report serves as a foundation or inspiration for further development of CO2-eq calculations. Emissions from construction and maintenance operations are defined as indirect emissions for Gothenburg Port Authority. The second objective is to collect data for the mass of materials and volume of fuels used in construction and maintenance operations for the Port of Gothenburg. Data from year 2013 is used for the collection of used materials and energy related products. The study includes the 22 most extensive projects out of 160 construction and maintenance related projects. The third objective is to calculate and asses CO2-eq emissions from construction and maintenance operations for the port of Gothenburg. The chosen method for calculating emissions is a carbon footprint assessment and includes a CO2-eq inventory on construction and maintenance operations at the Port of Gothenburg. The carbon footprint assessment uses emission factors in all calculations. The material and energy related products that contribute the most to CO2-eq emissions are fossil fuels and concrete. The total CO2-eq emissions for the 22 projects are approximately 1340 tonnes and in mass approximately 1060 tonnes (excluding fuels). This leads to an increase of 1 % of the current carbon footprint for Gothenburg Port Authority. If using an uncertainty factor with 25 % and including all 160 projects, CO2-eq emissions during 2013 are estimated to be up to 5600 tonnes, which is an increase with 3 %. The conclusions from the mapping and carbon footprint serve as a foundation for the development of guidelines, which operates as emission reduction potential areas. This is the last objective, including suggestions for guidelines on how to reduce CO2-eq emissions in port operations.
- PostA life cycle assessment of different fuel alternatives for Gothenburgs public transportation system(2015) Ghiassi Tari, Parisa; Chalmers tekniska högskola / Institutionen för energi och miljö; Chalmers University of Technology / Department of Energy and EnvironmentOne of the solutions for implementing a sustainable transport system, is to increase the use of public transportation and replacing fossil fuels with biofuels. In Gothenburg’s public transport system, there are no fuel alternatives that dominate the market yet. Currently, Volvo have stopped manufacturing biogas buses and instead changed focus towards electrified hybrid buses. The decision has concerned the biogas industry that expects a future competition between renewable fuels in Gothenburg. The purpose of this thesis is to assess and investigate the competitiveness of biodiesel (RME), biogas (from sewage sludge) and biodiesel plug-in hybrids for public buses in Gothenburg. Objectives include, a well-to-wheel life cycle assessment (LCA) for the different fuel alternatives that will indicate their environmental performance, and a survey that aims to indicate possible market potentials and barriers. The following environmental impact categories were included in the LCA: Global Warming Potential (GWP), Acidification Potential (AP), Eutrophication Potential (EP), Photochemical ozone creation potential (POCP), and Particles (PM). The results indicate that the environmental impacts per MJ fuel of biodiesel plug-in hybrids in the categories GWP, AP, POCP and particles are small compared to petrodiesel. Biodiesel performs well in comparison to petrodiesel in GWP and POCP. Biogas has the best environmental performance in the impact categories EP and PM while plug-in hybrids have the best environmental performance in GWP and POCP. However, if the batteries are included in the LCA plug-in hybrids, they have the highest environmental impacts among the three renewable fuel alternatives. Petrodiesel has the best environmental performance in AP. The survey indicates that cost and policy targets are the driving market barriers, but also that market potentials can be strengthened through introduction of emerging fuel technologies and better cooperation between stakeholders. Based on the Euro IV emission standard, all analyzed fuels have in general lower environmental impacts per MJ fuel compared to petrodiesel. Therefore, the competiveness of renewable fuel alternatives in Gothenburg, isn’t primarily based on their relative environmental performance. Cost and social aspects are potentially important aspects that should be further investigated. It is also recommended to perform more LCA studies, with different scope, functional unit, allocation methods etc., to better understand the environmental performance of different fuel alternatives.
- PostA multi-criteria decision analysis of alternative fuels for the(2017) Månsson, Stina; Chalmers tekniska högskola / Institutionen för energi och miljö; Chalmers University of Technology / Department of Energy and EnvironmentThis study assesses the prospect of renewable fuels in the shipping sector by conducting a multi-criteria decision analysis of selected alternative fuels with a panel of stakeholders. This provides an initial assessment of the importance of different factors influencing the choice of alternative marine fuel from a stakeholder perspective. Four alternative marine fuels, liquefied natural gas (LNG), methanol produced from natural gas (NG-MeOH), methanol produced from biomass (Bio-MeOH), and hydrogen produced from electrolysis by wind power (Elec-H2), are assessed towards 10 criteria using the analytic hierarchy process. The panel of stakeholders judging the importance of criteria valued economic criteria highest, followed by social criteria, environmental criteria and technical criteria. The relative importance between the criteria are not large, and the most preferred alternative marine fuel turned out to be electrolytic hydrogen from renewable energy sources when considering the joint preference of the stakeholders. The ranking order of fuels changes to some extent when different actors alone judge the importance of criteria, but electrolytic hydrogen turned out to be the most preferred option in most cases. However, international collaboration and technology specific policies and subsidies are most likely needed, and new infrastructure must be built, if electrolytic hydrogen is to be the dominating marine fuel in the future.

- PostActivity-based modeling of domestic energy demand with high time resolution - A case study on Gothenburg(2015) König, Christina; Chalmers tekniska högskola / Institutionen för energi och miljö; Chalmers University of Technology / Department of Energy and EnvironmentIn domestic buildings, a great potential to reduce energy consumption exists. To achieve this reduction, a more detailed understanding of the energy demand is required. Currently, there is sufficient information on an aggregated level. Nevertheless, further knowledge about the timing of the energy use is needed. Previous attempts to gain that knowledge are mostly based on conclusions from measurements. However, in this study a bottom up, activity-based modeling approach is chosen. Hence, knowledge can be increased on a more detailed level and the generation of synthetic load curves can be facilitated. The derived model focuses on residential buildings and is applied in a case study on Gothenburg, Sweden. Existing bottom-up models are mostly focused on specific dwellings and require a large amount of detailed input data. In contrast, the goal of the present report is a simple model with as few input parameters as possible. Thus, it can be quickly applied and transferred to other cities in Europe to get a first estimation on the composition of the energy demand. The practicality of such a model and its limitations are assessed by the present study. Furthermore, areas with low data availability and uncertain data should be identified. To gain more understanding of the timing of energy use, four end-uses are modeled. Those are electrical appliances, lighting, hot water and heated rooms. The major focus lies on the consumer side. A large part of the work is the collection of reliable input data. Important input data sets are the time-use surveys and data about the weather (temperature, solar irradiation and natural illuminance). The modeling of the hot water and the electrical appliances is heavily based on the time-use surveys. For the lighting those are combined with the natural illuminance. To model the space heating demand, the energy balance over the building envelope is calculated and combined with information on the external temperature, the solar irradiation and the building stock. The developed model can be used to predict the general shape of the demand curve in a residential area. However, the levels of the peak are rather uncertain. Nevertheless, in combination with measurements of the aggregated demand the model can be a useful tool to assess the current situation in an existing city. The input data needed to model the demand curve’s shape is extractable from established, official sources and data bases. That data II ABSTRACT includes weather data and time use data. Since that is available for other European countries, the model could be transferred to different cities. From the present study, it can be concluded that the time-use surveys are a promising tool for energy load curve modeling. Moreover, it could be detected how and where those surveys can be adjusted for that purpose.

- PostAn Urban Climate Model for Use in Strategic Environmental Assessment - Case: Creating a Climate Change Resilient Ng’ambo, Zanzibar City(2016) Luhr, Maike; Chalmers tekniska högskola / Institutionen för energi och miljö; Chalmers University of Technology / Department of Energy and EnvironmentThe urban climate has become a vital consideration for many populations as the effects of climate change are becoming increasingly prevalent. The climate in cities is different compared to rural areas, not least because of the minimal vegetation and the characteristics of building materials. As cities are getting hotter and heat-related mortality is increasing, eyes of urban planners and politicians are turning towards the necessity of climate change adaptation. The responses turned to often involve downscaling climate change projections to cover the local climate in order to have a basis for local adaptation strategies. However, within the scientific field of urban climatology, the differences between urban and rural temperatures have been documented and observed for over 100 years. The use of this knowledge could lead to more effective and site-specific climate change adaptation measures in city planning. To effectively integrate urban climatology into adaptation strategies it needs to be addressed at an early stage. An available methodology that could embrace these issues is for example Strategic Environmental Assessment (SEA), an internationally accepted and standardized tool which is adaptable to a broad variety of contexts. Developing countries are more vulnerable to, and also face the highest projections of, climate change. Here adaptation measures are needed that are economically, socially and environmentally justifiable whether projected climate hazards occur or not. Again, SEA might prove to be a viable tool for finding these low-key adaptation measures. This study does not perform an SEA, but borrows its methodology and structure in a case study performed on the archipelago of Zanzibar. Within this methodology an easy-accessible urban climate model is used which makes the expertise of urban climatology available to urban planners and non-climate-experts. The study shows that increased vegetation and water, together with reduced building density and mass, can cause significant temperature reductions in urban areas. These differences are actually larger than the expected temperature increases due to global warming. Even though a simple model is used and the results need to be more thoroughly verified, the outputs can provide rough guidance early in a planning process. The main recommendation reached in the case study include ensuring a surface cover composition that encompasses a high degree of vegetation. Further it is recommended to consider building mass and density and finally to give the climatic properties of buildings materials some thought.
- PostApplying circular economy principles in the oil & gas industry - An LCA study of the decommissioning process of offshore platforms(2017) Terpou, Aikaterini; Chalmers tekniska högskola / Institutionen för energi och miljö; Chalmers University of Technology / Department of Energy and EnvironmentMany offshore platforms are soon to reach or have already reached their mature phase, which means that in the foreseeable future, measures will need to be taken for their eventual removal. After their decommissioning, these platforms are a potential source of huge amounts of materials. The current study aimed to investigate how the oil & gas industry can improve its environmental performance by implementing the Circular Economy principles during the decommissioning process. More concretely, it was hypothesized that the environmental performance of the system would change if reuse was involved in the final stages of decommissioning. For these purposes, the Life Cycle Assessment procedure was implemented. The results show that partial decommissioning is a better option than complete decommissioning due to lower energy use during recycling and transportation. The results of a reuse scenario suggest that the environmental impacts of both decommissioning methods are reduced. Sensitivity analysis indicated that when the percentage of reuse is increased, the performances of complete and partial decommissioning from an environmental perspective both improve. This thesis concludes that optimising marine vessels used for transporting a platform’s pieces could help reduce emissions from that particular process. At the same time, reducing the amount of material that goes to recycling by increasing the reuse of certain assets of the platform, would improve the environmental performance of these decommissioning stages. It was also identified that there is a need for data transparency in the decommissioning field in order to produce more certain and accurate results.
- PostAspects of Sustainable Wastewater Treatement - A Case Study of AkzoNobel PPC Conducting MFA of Nitrogen(2017) Karlsson, Victoria; Chalmers tekniska högskola / Institutionen för energi och miljö; Chalmers University of Technology / Department of Energy and EnvironmentWater is a building block of life as well as being a valuable energy source. Ensuring that water bodies are not harmed by human actions is essential. Laws and policies govern water management including the general framework of wastewater treatment. Wastewater from industrial processes can contain toxic pollutants and nutrients which cause eutrophication and must therefore be properly treated. In this study AkzoNobel Pulp and Performance Chemicals in Bohus, Sweden, and its’ central wastewater treatment plant, Centrala Reningsverket (CRV), are used as case examples. In the CRV there has been an issue of growth of biological matter which has a possible correlation with the trend of the increasing suspended solids concentration. To assess if the growth was dependent on the nutrient nitrogen, two different types of studies were conducted. Firstly, a growth identification was attempted which resulted in the conclusion that it consists of different species of bacteria, algae and uni-cellular organisms. Secondly, two Material Flow Analysis (MFA) studies were conducted where the stocks and flows of nitrogen were mapped. One MFA was conducted over the entire Bohus site and one was conducted over the CRV to see if there existed any correlations with the growth. Large stocks and flows of nitrogen do exist at the Bohus site. The results for the MFA of the CRV were statistically uncertain, however, they did hint towards a correlation with the growth. This indicates that the hypothesis regarding the growth being dependent on nitrogen as a nutrient is most likely correct. For removal of biological growth, disinfectants such as Chloride compounds are the most common approach, however these are highly toxic to higher life forms and microorganisms. To hinder further growth, wastewater flows with higher nitrogen concentrations should be rerouted away from the CRV when possible. It is necessary to treat wastewater so as to not pollute water bodies or poison human, animal and plant life. However, the treatment methods should be of a sustainable nature to ensure no adverse effects occur elsewhere. Wastewater treatment is a very energy intensive process whereas both facilities and technologies used should be energy efficient.

- PostAssessing the Potential for Directing Electrification Towards Productive Use in Rural Mozambique(2012) Jakobsson, Niklas; Karheiding, Carl; Chalmers tekniska högskola / Institutionen för energi och miljö; Chalmers University of Technology / Department of Energy and EnvironmentIt is generally accepted that electricity brings a number of social benefits such as better healthcare, better education, increased security due to street lightning and lower household expenditure due to a cheaper light source. Electricity is also expected to bring economic benefits in the form of income-generating opportunities, this happens less regularly and it cannot be expected that production springs from the ground once electricity arrives to a region; a larger understanding of the connection between electrification and its effect on production is therefore needed. Our Master of Science thesis describes the methodology behind, and the results of, an 8 week field survey on the connection between rural electrification and productive use carried out in the province of Cabo Delgado in northern Mozambique. The idea is to investigate if existing production can be utilized as an anchor for electrification in the sense that it can either provide a strong consumption basis to increase the economic viability for grid extension, or if it can be utilized for larger income-generation when electrified. The project springs from an idea in the scientific literature to identify productive activities in rural settings and utilize them as anchors in the described sense. Specifically an electrification project in Ribaue district in northern Mozambique is frequently cited as a success story when utilizing productive use in electrification processes. The results show that there are not enough, or large enough, production units on the countryside in northern Mozambique for any of them to be utilized as an anchor in the hoped sense and thereby that the example from Ribaue is not reproducible generally. The only wide-spread type of production is milling, this activity is too small to generate any substantial incomes from the electric utility and its income-generating effect for a village is, compared to the number of inhabitants, limited; larger activities are limited to one cotton factory, two cashew nut processing factories, a couple of saw mills and a couple of salt production sites (excluding tourism). The cotton factory is the single most substantial electricity anchor, both from supplier perspective and due to its income generating effect on the local people. Finally, to effectively utilize productive use for income generation, we give the recommendation for a multi-cooperative effort between the government, foreign aid institutions and NGOS to spur simultaneous creation of infrastructural, complementary service and additional business project expansion. In the light of this recommendation, the emphasis on existing production represents a shortcut that we do not feel is possible to take in northern Mozambique.
- PostAssessing the Sustainability of First Generation Ethanol for Bioethylene Production(2016) Qvint, Kristina; Melander, Amanda Nordqvist; Chalmers tekniska högskola / Institutionen för energi och miljö; Chalmers University of Technology / Department of Energy and EnvironmentThe majority of plastic materials today are petroleum based making the plastics industry is one of the drivers of oil extraction. To portray a greener image and decrease the industry’s need for oil, some plastics producers have started using bioethanol as a feedstock. Within the next five years, the demand for bioplastics is expected to increase by about 19 %, increasing the demand for ethanol. Traditionally, ethanol is mainly used as a sustainable alternative to fossil fuels. Lately however, there has been much debate regarding if ethanol really is a better alternative for the environment. This study assesses the sustainability of first generation ethanol on behalf of the petrochemical company Borealis AB. The company is looking into the possibility to produce ethanol-based biopolyethylene. Borealis AB is part of the project Locally Grown Plastics, aiming to produce packaging material from second generation ethanol from Swedish forestry residues. This project is still 5-10 years away from realization, however, Borealis AB are considering commencing their production of bioplastics earlier, using first generation ethanol. Scientific literature, certification schemes, and a study of actors in the ethanol industry, show that ethanol can be produced in a manner that makes it a more sustainable option for plastics production than oil. To assess the sustainability of ethanol producers in Brazil, the US and Africa, a framework was constructed. After applying the framework, comparing different feedstocks for ethanol, and looking at the certified biomass potential, three Brazilian suppliers were deemed most promising. These are recommended as the best options for Borealis, should they decide to produce bioplastics from first generation ethanol. It is concluded that first generation ethanol can be a viable choice of feedstock for a European bioplastics producer, such as Borealis AB. However, appropriate and credible certification must obtained by the ethanol suppliers to ensure the sustainability of their practice. Brazilian sugarcane ethanol is found to be the most sustainable alternative and three companies operating in the area are recommended as suppliers for Borealis AB.

- PostBackcasting Approach to Sustainable - Stakeholders’ Perspectives on Challenges, Barriers, and Opportunities for Sustainability Transition.(2014) Valadez Garcia, Diana; Sen, Burak; Chalmers tekniska högskola / Institutionen för energi och miljö; Chalmers University of Technology / Department of Energy and EnvironmentChallenges coming along with global sustainability issues, e.g. climate change, cannot be solved with conventional, linear thinking approaches. Transition towards sustainability is a non-linear process and involved a wide variety of actors. Therefore it requires in-depth understanding of barriers and drivers that disable or enable transition in the current unsustainable system. Adopting systems perspective with backcasting approach and inspired by the “think global, act local” paradox, the Challenge Lab project takes on the present challenges in the unsustainable transport system in Gothenburg, Sweden by introducing a new two-phased methodology, called ‘the Challenge Lab (C-Lab) process’, to address a societal challenge. The first phase focuses on understanding the system from different perspectives to identify critical leverage points and helps intervene in ill-structured systems. The second phase consists of a study that identifies the challenges, barriers, and opportunities in the transport system of Gothenburg, based on opinions gathered from the interviews with 10 stakeholders. These challenges, barriers and opportunities are shown on the conceptual model of the system. Unlike similar studies considering Gothenburg as the case city, the present master’s thesis covers both passenger and goods transport, and considers academy – in addition to industry and government- as another relevant stakeholder. The new methodology was useful to have a systemic understanding of the complexity and dynamics of societal challenges. The findings showed that collaboration between the stakeholders and integration of transport into the city planning are among the main challenges towards a sustainable transport system, but could become opportunities, if addressed. Main barriers identified are the limited space in the city and the politician’s fear of loss when proposing and implementing sustainable strategies. The findings also revealed that the majority of the stakeholders interviewed think that there is no or partially consensus on the vision for sustainable transport system in Gothenburg. The transition towards a sustainable transport system can be achieved by increasing dialogue among stakeholders and by having a ‘systems thinking perspective’ when planning the future transport system of the city.
- PostBehavioural roots and system effects of residential electric heating DSM(2017) Dahlman, Yrsa; Gerhardsson, Hanna; Chalmers tekniska högskola / Institutionen för energi och miljö; Chalmers University of Technology / Department of Energy and EnvironmentIn a wind dominated future electricity system, consequences of intermittency can be reduced through residential demand side management (DSM), but studies on this subject generally lack understanding of resident behaviour. This work is an interdisciplinary master's thesis, aiming to bridge the gap between behavioural studies and electricity systems modelling. The work is carried out at the Department of Energy and Environment at Chalmers University of Technology, in cooperation with the research group of Environmental Psychology at Gothenburg University, and relates to previous electricity system research on DSM of electric heating in Swedish single family dwellings (SFDs) in a future scenario of a north European wind dominated electricity system. A survey is sent out and answered by 338 E.ON customers living in SFDs. The survey answers are used to model the potential for Swedish electric heated SFDs to reduce costs and emissions in a wind dominated northern European electricity system by accepting variations in their indoor temperatures. The outcome shows that there is potential to reduce electricity demand by around 1.6TWh/year, costs by around 120M€ and (0 2 emissions by around 870 tonnes by applying DSM in all Swedish SFDs with electric heating. If it is desired to stimulate additional DSM efforts in SFDs it is found that system benefits are larger when making the household's accept a slight increase in variations all time, rather than allowing for a significant increase in temperature variations at times when no one is home. It is found that people are overall willing to participate in the DSM-scheme and that they are mainly motivated by the environmental benefits, regarding DSM as mitigating the social dilemma of climate change. The main factor explaining the participation level is found to be the respondents awareness of the connection between electricity use and climate change. Further research is suggested for residential DSM in other system contexts, such as countries without hydropower which can be expected to be more affected by wind intermittency. Future pilot studies investigating actual, rather than theoretical, household participation and experiences of temperature variations are also suggested.
