… [kg CO2-eq./ functional unit].The purpose of this thesis is to examine how electricity, district heating, hotels, taxis, food and materials affect the climate and how emission factors for these areas can be calculated.This was done by reviewing and comparing different studies …
… to the biogas plant. The objective of this study was therefore to make an electricity and heat survey of the biogas plant, a detailed study of the heat consumption in the sanitation step and also a comparison of energy consumption with the present sanitation method and an …
… on replacing OKG's oldest reactor O1. Furthermore the project focused on just electricity production and combustion with CFB-boilers. Due to the Economic analysis the plant will not be profitable in the current situation. The plant profitability was examined by the net present …
en projektanalys utifrån ett företagsekonomiskt perspektiv
… the CHP for pasteurization of milk in the dairy plant. This would reduce the electricity costs and get a positive net present value. Including a 30 percent subsidy the investment generates a higher net present value and the modified pay-off period will be 10,3 years. The …
… specifications. These technical specifications have been used to simulate the electricity production and the economical yield of each type of examined solution. The investigation shows that the best solution is the solution with several small turbines with asynchronous …
längs Annetorpsvägen i Hyllie, Malmö
… barriers combined with photovoltaics along Annetorpsvägen to generate solar electricity. To quantify the losses that shadows from buildings along the roadmight cause, a 3D-model of the area was constructed in SketchUp. This digital model made it possible to simulate shadows and …
miljö- och systemkonsekvenser
… analysis has been performed on the result of simulations of differentheat and electricity production alternatives. The alternatives simulated wereone where Vattenfall Nyköping covers the base load in the joint district heatingsystem and two where the power plant at SSAB …
… water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most …
Kontorsbyggnad med solvärmeproduktion - en fallstudie
… At the same time it is increasingly common with self-producers of heat and electricity generation. The main purpose with this master thesis is to investigate how time resolution affects the environmental assessment of energy consumption in office buildings connected to district …
- med fokus på Organisk RankineCykel (ORC)
… towards sustainable options. One alternative is cogeneration, which means that electricity and heat is produced in one plant. The purpose with this survey is to examine if there are any commercial available combined heat and power techniques, based on combustion of solid moist …

… and used to draw conclusionsabout the costs for production of heat and electricity with different conversion technologies.The model uses climate data to simulate the variations in heat energy demand on a day-to-day basis.The given heat demand is the base of the simulation and …
… is a too big investment for most farmers and the production surplus of gas or electricity cannot be connected to the existing grid. Separation of manure would on the other hand enable longer transports of the P-rich solid fraction, which would improve the nutrient balance on a …
… is produced from the residual biomass by anaerobic digestion and then the electricity that can be produced is supplied to the production of biodiesel. When the oil is converted into biodiesel it also produces glycerine that has multiple uses and is sold to other companies. The …
