Method and models used in the project Pathways to Sustainable European Energy Systems
- 2011
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- This book describes the research that has been carried out during the first period (2006-2010) of the Alliance for Global Sustainability (AGS) project "Pathways to Sustainable European Energy Systems". this interdisciplinary project involves more that 40 researchers and addresses various aspects of the challenges faced in transforming the European energy system. Presented in this book are the energy-related methods and models that originate from different scientific disciplines and traditions and that were applied in the Pathways project. Some of the analytical tools are well-known, well-documented, and widely used in academic research. Others have been developed (or refined) during the Pathways project and are therefore unique. The chapters of this book cover around 30 different methods and models used in the Pathways project and presents an overview of the processes through which the research was conducted and the methods and models were co-ordinated.

Konferensbidrag (refereegranskat)abstract
- Two different methodologies, one top-down and one bottom-up, are presented for estimating potential future energy demand for space and water heating in the existing building stock of the residential sector to 2030. Two future price scenarios are used as inputs. The work is tested using data for the existing Swedish residential building stock. Compared to 2005 levels of energy use (74 TWh) the bottom-up model shows reductions to 52 TWh and 50 TWh for the two price scenarios, respectively. Results from the top-down model are 11 % (8 TWh) and 7 % (5 TWh) higher than those of the bottom-up model for the two price scenarios. This suggests that the price mechanism alone will not be sufficient to achieve the full techno-economic potential for energy efficiency.

Konferensbidrag (refereegranskat)abstract
- This paper provides some initial results from the project "CCS in the Skagerrak/Kattegat-region" which is an intraregional CCS project partly funded by the EU. The project assesses the prospects for Carbon Capture and Storage (CCS) from industry and power plants located in the Skagerrak region which comprises northern Denmark, south-east coast of Norway and the west coast of Sweden. The project is a joint cooperation between universities, research institutes and industries in the region. The methodology used in one of the project work packages is presented together with some initial results on legal aspects. CCS in the Skagerrak region may potentially account for a third of combined emission reduction commitments by 2020 in the three countries involved in the project. Yet, much of the emissions in the region occur from industry (in addition to power plants) and it is still not clear how these industries will be treated under the ETS. Based on current knowledge, a good storage option would be in the Hanstholm aquifer on Denmark's northwest coast. The phasing-in of capture plants over time is central to the development of a cost efficient CCS infrastructure. However, many of the sources in the region are located at a port facilitating use of boat transport through the build-up period. The initial legal analysis show that significant regulatory uncertainties exist in the region with regard to CCS and it is not obvious that the implementation of the EU CCS directive into national law by June 2011 will alleviate these uncertainties. Finally, the project may provide a significant test case for what type of political and regulatory cooperation that will be required if CCS is to be deployed in a transboundary context under conditions of sufficient public acceptance and well-designed regulation. © 2011 Published by Elsevier Ltd. © 2011 Published by Elsevier Ltd.

Tidskriftsartikel (refereegranskat)abstract
- The present biofuel policies in the European Union primarily stimulate 1st generation biofuels that are produced based on conventional food crops. They may be a distraction fromlignocellulose based 2nd generation biofuels – and also from biomass use for heat and electricity – by keeping farmers’ attention and significant investments focusing on firstgeneration biofuels and the cultivation of conventional food crops as feedstocks. This article presents two strategies that can contribute to the development of 2nd generation biofuels based on lignocellulosic feedstocks. The integration of gasification-based biofuel plants in district heating systems is one option for increasing the energy efficiency and improving the economic competitiveness of such biofuels. Another option, biomass co-firing with coal,generates high-efficiency biomass electricity and reduces CO2 emissions by replacing coal. It also offers a near-term market for lignocellulosic biomass, which can stimulate development of supply systems for biomass also suitable as feedstock for 2nd generation biofuels. Regardless of the long-term priorities of biomass use for energy, the stimulation of lignocellulosic biomass production by development of near term and cost-effective markets isjudged to be a no-regrets strategy for Europe. Strategies that induce a relevant development and exploit existing energy infrastructures in order to reduce risk and reach lower costs, are proposed an attractive complement the present and prospective biofuel policies.

European Energy Pathways - Pathways to sustainable european energy systems
- 2011
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- To meet the challenge of climate change, the world must substaintially reduce emissions of greenhouse gases (GHGs). this must be accomplished in a way that maintains security of supply and competitiveness.This book presents to pathways towards sustainable European energy systems - the "Policy Pathway" and the "Market Pathway". These to pathways differ with respect to where the main responsability lies for transforming the energy system in following the pathway. The Policy pathway takes its departure from the EU Energy and Climate Package, and has a strong focus on targeted policies that promote energy efficiency and energy from renewable sources. The Market Pathway relies more on the market to transform the energy system, and presents a future in which the cost associated with emitting CO2 (and other GHGs) is the dominating policy measure.This book describes the research that has been carried out during the first period (2006-2010) of the AGS project "Pathways to Sustsainable Energy Systems". This interdisciplinary project involved more than 40 researchers and addressed various aspects of the challenges faced in transforming the European energy system. The chapters in this book cover more than 30 topics and presents an overall picture of the results obtained to date from various activities in the Pathways project.

The importance of CO2 Capture and Storage - a geopolitical discussion
- 2011
-
Ingår i: The 6th Dubrovnik Conference on Sustainable Development of Energy, Water and Environment Systems.
-
Konferensbidrag (refereegranskat)abstract
- The CO2 capture and storage (CCS) technology is now considered to be one of the key options for climate change mitigation. This paper discusses the implications for the further development of CCS, particularly with respect to climate change policy in an international geopolitics context.The rationale for developing CCS should be the over-abundance of fossil fuel reserves (and resources) in a climate change context. From a geopolitical point, it can be argued that the most important outcome from the successful commercialisation of CCS will be that fossil fuel-dependent economies will find it easier to comply with stringent greenhouse gas (GHG) reduction targets (i.e. to attach a price to CO2 emissions). This should be of great importance since, from a geopolitical view, the curbing on GHG emissions cannot be isolated from security of supply and economic competition between regions. Thus, successful application of CCS may moderate geopolitical risks related to regional differences in the possibilities and thereby willingness to comply with large emission cuts. In Europe, application of CCS will enhance security of supply by fuel diversification from continued use of coal, especially domestic lignite. In contrast, failure to implement CCS will require that the global community, including Europe, agrees to almost immediately to start phasing out the use of fossil fuels, an agreement which seems rather unlikely, especially considering the abundant coal reserves in developing economies such as China and India.

Future demand for space heating in buildings: a top-down analysis
- 2011

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- If the trends in energy demand for residential sector space heating seen inSweden from 1970 to 2005 continue, total demand is predicted to fall from52 TWh to 47 TWh by 2050. This fall will occur despite projected increasesin average dwelling size and population size. This is because the unit consumption(kWh/m2) of energy use for space heating continues to fall and itstrajectory will offset increases in demand attributable to increases in averagedwelling size and population size. These figures correspond to a reduction inunit consumption for energy for space heating from 125 kWh/m2 to between60 kWh/m2 and 74 kWh/m2. This fall can be amplified through higherenergy prices and increased energy efficiency, to reduce the total to 37 TWh(60 kWh/m2). However, the price elasticity of demand for energy for heatingin dwellings has been found to be very low (-0.16), which means that improvementsin energy efficiency brought about by direct regulatory intervention andincremental technical breakthroughs are of greater importance.

Modelling Energy demand to 2050 in the EU Building Stock – a bottom-up analysis
- 2012
-
Ingår i: Proceedings of World Sustainable Energy Days conference, 29th - March 2nd 2012 , Wels, Austria.
-
Konferensbidrag (refereegranskat)abstract
- Lowering absolute energy demand in buildings is a key policy goal of the EU. This is to be achieved primarily through improvements in end use efficiency. This paper presents results of a modelling work which examines three different scenarios for efficiency of energy end uses for the EU 27 building stock to 2050. The model is a coarse bottom-up engineering variant. The model and scenarios applied are described and the results obtained are related to EU goals and aspirations for 2020 and 2050. Model outputs estimate that if energy efficiency was frozen at today’s level, expansion of the building stock and other increases in standards would increase final energy demand in the EU by almost 70% by 2050 whereas continuing efforts at efficiency along current rates could stabilise energy demand. A reduction consistent with the EU’s 20% efficiency improvement target for the year 2020 is also shown to be possible, but needs forceful policy for success. Results from the work also show that the EU aspiration for a reduction in CO2 emissions of 90 % from buildings by 2050 can be met via the penetration of biomass, district heating and heat pumps at the building level provided there is sufficient decarbonisation of the supply system as well.

The effect of improved efficiency on energy savings in EU-27 buildings
- 2013
-
Ingår i: Energy. - : Elsevier BV. - 0360-5442. ; 57, s. 134-148
-
Tidskriftsartikel (refereegranskat)abstract
- Utilising energy efficiency to lower energy demand in buildings is a key policy goal of the European Commission. This paper presents the results of bottom-up modelling to elucidate the impact of energy efficiency on the EU building stock up to 2050 under three different scenarios. The modelling is performed for eight individual EU countries and a ninth hypothetical entity that represents the remaining nineteen EU countries. The scenarios highlight the roles of different levels of efficiency improvements in the context of increasing floor area and the demand for energy services. From the results it can be concluded that the EC 2020 goals for primary energy savings can be met by focussing on a combination of minimum efficiency construction standards, improved conversion efficiency standards for final energy to useful energy, and a ≥2% annual improvement in end-use efficiency applied at the useful energy level. A comparison of the results obtained in the present study for Spain with the estimates of savings documented in the Spanish Energy Efficiency Action Plan indicate that the plan could lead to the closing of the energy efficiency gap for buildings in that country by 2020.
