The expanding energy justice scholarship increasingly discusses the importance of equity concerns in the context of global decarbonization. How to equitably distribute the benefits and burdens of energy systems and ensure an inclusive and socially acceptable change, constitutes vital prerequisites for the transition to a low-carbon society. Energy, in a Northern context, is seen as gender-neutral;
Concentrating solar power (CSP) technology with thermal energy storage is a renewable and emerging technology. In this work, dynamic models for analyzing and evaluating energy storage concepts and its interaction with the solar field and the power block have been developed. A physical model of a 50 MW CSP plant has been implemented in the modeling language Modelica. The models are developed in a m
Renewable energy sources (RES), especially wind turbines, have become more important during the last years. An increasing number of distributed generation (DG) units are connected to weak medium voltage distribution networks in rural areas where they have a large influence on the voltage and the line losses. Voltage rise is in this case often a limiting factor for the maximum amount of DG capacity
Environmental problems in the energy system often originate from everyday activities and choices. Everyday activities in the home are part of the private sphere that can be contested in relation to energy policies. This article discusses the public-private divide in energy policies and how Swedish municipal energy consultants understand the divide. By analyzing the actions of energy consultants an
Lignin from black liquor in the kraft pulping process is a potential raw material for production of renewable chemicals and fuels. However, an efficient extraction method for the lignin from the black liquor is needed. Therefore, two new processes have been designed, which both utilize membrane filtration for the isolation of lignin from the kraft black liquor. The first one includes precipitation
The need for biomass transportation depends on the balance between locally produced biomass and the local demand for fuel. In Sweden, more than 80% of the biomass assumed to be required to replace fossil fuels for the production of electricity and heat can be produced locally within each county, if biomass is extensively utilised. The average transportation distance of the remaining 20% will be be
This paper analyses the nature and scale of transaction costs (TCs) borne by obliged parties under a "Tradable White Certificate" (TWC) scheme. Taking the first phase of the Energy Efficiency Commitment (EECl) in Great Britain as a case study, several sources of TCs were considered, such as search for information, persuasion of customers, negotiation with business partners, and measurement and ver
This paper investigates how river privatisation in Turkey is deployed to expand renewable energy production and the implications this has for issues of ownership, rights to water and community life. Recent neoliberal reforms in Turkey have enabled the private sector to lease the rights to rivers for 49 years for the sole purpose of electricity production. The paper focuses on the re-scaling and re
Production of synthetic vehicle fuels from biomass is a hot topic. There are several alternative fuels to consider when evaluating properties such as cost of production and energy efficiency to both product and final use in a road vehicle. Thermochemical conversion via gasification and downstream synthesis of fuels as well as biochemical conversion of woody biomass to ethanol is considered in this
Popular Abstract in Swedish Etanol som produceras från förnyelsebara råvaror kan ersätta fossila bränslen som t.ex. bensin och diesel. Denna avhandling behandlar den enzymatiska processen för etanolproduktion från barrträd. Baserat på datorprogrammen Aspen Plus och Icarus Process Evaluator har ett verktyg för tekniska och ekonomiska beräkningar tagits fram i vilket hela processen, från trä till etEthanol produced from renewable resources can be used to replace fossil fuels such as gasoline and diesel. This thesis deals with the development of the enzymatic process used for ethanol production from softwood. A techno-economic tool, based on Aspen Plus and Icarus Process Evaluator, was developed in which the whole process, from raw material to ethanol, was studied and critical process paramet
District heating is well expanded in the residential areas in Sweden, although not in detached house areas. Increased environmental concerns as well as steadily increasing electricity and oil prices make the detached houses sector a potential market for the district heating companies. District heating in low heat density areas is economically challenging for mainly two reasons: Firstly, constructi
This report was developed under the ‘Users Technology Collaboration Programme (TCP) by the International Energy Agency (IEA) Task on Hard-to-Reach (HTR) Energy Users’. The Task aims to provide country participants with the opportunity to share and exchange successful approaches identifying and better engaging HTR energy users. Under the Task, HTR energy users are broadly defined as 'any energy use
Overvoltage is becoming increasingly prevalent in distribution networks with high penetration of renewable distributed energy sources (DERs). Local control of converter-based resources is a flexible and scalable method to prevent this growing issue. Reactive power is used for voltage control in many local control schemes. However, the typical range of R/X ratios for distribution power lines indica
Abstract in UndeterminedSometimes energy security is used as an advocacy for renewable energy systems. Although renewable energy systems can surely have such characteristics they will not per se solve all types of security problems, and new problems will most certainly arise. In this paper, energy security aspects of renewable energy systems are analysed taking the starting point in a broad typolo
