From Carbon Calculators to Energy System Analysis in Cities
Energies, 2019Co-Authors: David Drysdale, Brian Vad Mathiesen, Henrik LundAbstract:Energy Systems in cities need to be decarbonized and are becoming more integrated via Energy sector coupling. Today, cities often use simple methods to assess their low carbon targets, e.g., carbon calculators, and these methods use annualized carbon reduction potentials. For example, reductions from heat savings in buildings or fuel demand in transport. This is done because it is simple and fast. This paper describes a methodology that goes beyond carbon calculators and assesses highly renewable Energy Systems. The methodology is carried out for a case city—Sonderborg, Denmark. Using a national 100% renewable Energy study and a suitable Energy System Analysis tool (EnergyPLAN), the method accounts for inter-sector coupling and Energy System dynamics. The Energy System is assessed by comparing the results from the Analysis tool against numerous key sustainability factors for a Smart Energy System. The paper illustrates how the method delivers a sustainable 100% renewable Smart Energy System for Sonderborg, which can be part of the Danish Energy System in 2050 based on local resources. The paper discusses the broader applicability of the method within strategic Energy planning.

Chapter 4 – Tool: The EnergyPLAN Energy System Analysis Model
Renewable Energy Systems, 2014Co-Authors: Henrik LundAbstract:This chapter deals with the development of Energy System Analysis tools and methodologies that are suitable for the design and evaluation of smart Energy and renewable Energy System alternatives. The specific purpose of this chapter is to present the EnergyPLAN model and describe how to use it for the design of relevant alternatives. The EnergyPLAN model analyzes coherent Energy Systems on an aggregated basis and emphasizes the evaluation of potential synergies between the different subsectors. Thus, the model involves hourly balances of district heating and cooling as well as electricity and gas grids. It also includes a wide range of cross-sector technologies such as heat pumps, combined heat and power, electrolyzers, and electric vehicles as well as gasification, hydrogenation, and co-electrolyzers. The model is a freeware that has been widely used in different countries across the world. In this chapter, EnergyPLAN is described and compared to various other models.

the first step towards a 100 renewable Energy System for ireland
The Dubrovnik Conference on Sustainable Development of Energy Water and Environment Systems, 2011Co-Authors: David Connolly, Brian Vad Mathiesen, Henrik Lund, Martin J LeahyAbstract:In 2007 Ireland supplied 96% of the total Energy demand with fossil fuels (7% domestic and 89% imported) and 3% with renewable Energy, even though there are enough renewable resources to supply all the Energy required. As Energy prices increase and the effects of global warming worsen, it is essential that Ireland begins to utilise its renewable resources more effectively. Therefore, this study presents the first step towards a 100% renewable Energy-System for Ireland. The Energy-System Analysis tool used was EnergyPLAN, as it accounts for all sectors of the Energy-System that need to be considered when integrating large penetrations of renewable Energy: the electricity, heat, and transport sectors. Initially, a reference model of the existing Irish Energy-System was constructed, and subsequently three different 100% renewable Energy-Systems were created with each focusing on a different resource: biomass, hydrogen, and electricity. These Energy-Systems were compared so that the benefits from each could be used to create an 'optimum' scenario called combination. Although the results illustrate a potential 100% renewable Energy-System for Ireland, they have been obtained based on numerous assumptions. Therefore, these will need to be improved in the future before a serious roadmap can be defined for Ireland's renewable Energy transition.

Energy System Analysis of marginal electricity supply in consequential LCA
The International Journal of Life Cycle Assessment, 2010Co-Authors: Henrik Lund, Brian Vad Mathiesen, Per Christensen, Jannick Hoejrup SchmidtAbstract:Background, aim and scope This paper discusses the identification of the environmental consequences of marginal electricity supplies in consequential life cycle assessments (LCA). According to the methodology, environmental characteristics can be examined by identifying affected activities, i.e. often the marginal technology. The present ‘state-of the-art’ method is to identify the long-term change in power plant capacity, known as the long-term marginal technology, and assume that the marginal supply will be fully produced at such capacity. However, the marginal change in capacity will have to operate as an integrated part of the total Energy System. Consequently, it does not necessarily represent the marginal change in electricity supply, which is likely to involve a mixture of different production technologies. Especially when planning future sustainable Energy Systems involving combined heat and power (CHP) and fluctuating renewable Energy sources, such issue becomes very important. Materials and methods This paper identifies a business-as-usual (BAU) 2030 projection of the Danish Energy System. With a high share of both CHP and wind power, such System can be regarded a front-runner in the development of future sustainable Energy Systems in general. A strict distinction is made between, on the one hand, marginal capacities, i.e. the long-term change in power plant capacities, and on the other, marginal supply, i.e. the changes in production given the combination of power plants and their individual marginal production costs. Detailed Energy System Analysis (ESA) simulation is used to identify the affected technologies, considering the fact that the marginal technology will change from one hour to another, depending on the size of electricity demand compared to, among others, wind power and CHP productions. On the basis of such input, a long-term yearly average marginal (YAM) technology is identified and the environmental impacts are calculated using data from ecoinvent. Results The results show how the marginal electricity production is not based solely on the marginal change in capacity but can be characterised as a complex set of affected electricity and heat supply technologies. A long-term YAM technology is identified for the Danish BAU2030 System in the case of three different long-term marginal changes in capacity, namely coal, natural gas or wind power. Discussion Four analyses and examples of YAMs have been used in order to present examples of the cause–effect chain between a change in demand for electricity and the installation of new capacity. In order to keep open the possibilities for further Analysis of what can be considered the marginal technology, the results of four different situations are provided. We suggest that the technology mix with the installation of natural gas or coal power plant is applied as the marginal capacity. Conclusions The environmental consequences of marginal changes in electricity supply cannot always be represented solely by long-term change in power plant capacity, known as the long-term marginal technology. The marginal change in capacity will have to operate as an integrated part of the total Energy System and, consequently, in most Energy Systems, one will have to identify the long-term YAM technology in order to make an accurate evaluation of the environmental consequences. Recommendations and perspectives This paper recommends a combination of LCA and ESA as a methodology for identifying a complex set of marginal technologies. The paper also establishes values for Danish marginal electricity production as a yearly average (YAM) that can be used in future LCA studies involving Danish electricity.

Transitioning to a 100% renewable Energy System in Denmark by 2050: assessing the impact from expanding the building stock at the same time
Energy Efficiency, 2019Co-Authors: David Drysdale, Brian Vad Mathiesen, Susana PaardekooperAbstract:Residential and service (office) buildings consume a large proportion of primary Energy in Europe in the form of electricity and all other Energy carriers. In response to this, the concept of near Zero Energy Buildings (nZEB) has been developed. These buildings have very low Energy demands and integrate renewable Energy to supply residual demand. nZEBs aim to increase Energy efficiency from a demand-side user perspective. When looking at the entire Energy System, there are also Energy efficiency gains to be achieved on the supply-side. For example, from a district heating System. If an Energy System becomes more efficient on the supply-side, then the question is how much Energy needs to be saved on the demand-side, for instance by low Energy buildings such as nZEBs. The purpose of this paper is to analyse and understand the implications from building new low Energy buildings, i.e. nZEBs, within an Energy System that is (a) transitioning to 100% renewable Energy and (b) has substantially improved supply-side Energy efficiency. A case study from Denmark is used to understand the outcome for the Energy System when these new buildings are built in this context. The methodology and results of this study could be replicated for other European countries as well. The Analysis looks at the total Energy System heat savings, costs and biomass consumption. The paper shows that these new low Energy buildings with very low heat demand do not deliver the expected benefits for the 100% renewable Energy System transition in Denmark. This is due to the increased efficiency and flexibility of the Energy supply System in the future. However, deep renovations of existing buildings are necessary. Furthermore, this paper demonstrates based on the Danish case, that as European countries decarbonise their Energy Systems over the next decades, they will need to carry out detailed Energy System Analysis to determine the extent to which heat demand should be reduced in buildings within the context of the transitioning Energy System.

the role of district heating in future renewable Energy Systems
Energy, 2010Co-Authors: Henrik Lund, Brian Vad Mathiesen, Bernd Moller, Anders DyrelundAbstract:Based on the case of Denmark, this paper analyses the role of district heating in future Renewable Energy Systems. At present, the share of renewable Energy is coming close to 20 per cent. From such point of departure, the paper defines a scenario framework in which the Danish System is converted to 100 per cent Renewable Energy Sources (RES) in the year 2060 including reductions in space heating demands by 75 per cent. By use of a detailed Energy System Analysis of the complete national Energy System, the consequences in relation to fuel demand, CO2 emissions and cost are calculated for various heating options, including district heating as well as individual heat pumps and micro CHPs (Combined Heat and Power). The study includes almost 25 per cent of the Danish building stock, namely those buildings which have individual gas or oil boilers today and could be substituted by district heating or a more efficient individual heat source. In such overall perspective, the best solution will be to combine a gradual expansion of district heating with individual heat pumps in the remaining houses. Such conclusion is valid in the present Systems, which are mainly based on fossil fuels, as well as in a potential future System based 100 per cent on renewable Energy.

Long-term affected Energy production of waste to Energy technologies identified by use of Energy System Analysis
Waste Management, 2010Co-Authors: Marie Munster, Peter MeibomAbstract:Affected Energy production is often decisive for the outcome of consequential life-cycle assessments when comparing the potential environmental impact of products or services. Affected Energy production is however difficult to determine. In this article the future long-term affected Energy production is identified by use of Energy System Analysis. The focus is on different uses of waste for Energy production. The Waste-to-Energy technologies analysed include co-combustion of coal and waste, anaerobic digestion and thermal gasification. The Analysis is based on optimization of both investments and production of electricity, district heating and bio-fuel in a future possible Energy System in 2025 in the countries of the Northern European electricity market (Denmark, Norway, Sweden, Finland and Germany). Scenarios with different CO{sub 2} quota costs are analysed. It is demonstrated that the waste incineration continues to treat the largest amount of waste. Investments in new waste incineration capacity may, however, be superseded by investments in new Waste-to-Energy technologies, particularly those utilising sorted fractions such as organic waste and refuse derived fuel. The changed use of waste proves to always affect a combination of technologies. What is affected varies among the different Waste-to-Energy technologies and is furthermore dependent on the CO{sub 2} quota costs andmore » on the geographical scope. The necessity for investments in flexibility measures varies with the different technologies such as storage of heat and waste as well as expansion of district heating networks. Finally, inflexible technologies such as nuclear power plants are shown to be affected.« less

Comparing Waste-to-Energy technologies by applying Energy System Analysis
Waste Management, 2010Co-Authors: Marie Munster, Henrik LundAbstract:Even when policies of waste prevention, re-use and recycling are prioritised a fraction of waste will still be left which can be used for Energy recovery. This article asks the question: How to utilise waste for Energy in the best way seen from an Energy System perspective? Eight different Waste-to-Energy technologies are compared with a focus on fuel efficiency, CO2 reductions and costs. The comparison is carried out by conducting detailed Energy System analyses of the present as well as a potential future Danish Energy System with a large share of combined heat and power as well as wind power. The study shows potential of using waste for the production of transport fuels. Biogas and thermal gasification technologies are hence interesting alternatives to waste incineration and it is recommended to support the use of biogas based on manure and organic waste. It is also recommended to support research into gasification of waste without the addition of coal and biomass. Together the two solutions may contribute to alternate use of one third of the waste which is currently incinerated. The remaining fractions should still be incinerated with priority to combined heat and power plants with high electric efficiency.

use of waste for heat electricity and transport challenges when performing Energy System Analysis
Energy, 2009Co-Authors: Marie Munster, Henrilk LundAbstract:This paper presents a comparative Energy System Analysis of different technologies utilising organic waste for heat and power production as well as fuel for transport. Technologies included in the Analysis are second-generation biofuel production, gasification, fermentation (biogas production) and improved incineration. It is argued that Energy technologies should be assessed together with the Energy Systems of which they form part and influence. The Energy System Analysis is performed by use of the EnergyPLAN model, which simulates the Danish Energy System hour by hour. The Analysis shows that most fossil fuel is saved by gasifying the organic waste and using the syngas for combined heat and power production. On the other hand, least greenhouse gases are emitted if biogas is produced from organic waste and used for combined heat and power production; assuming that the use of organic waste for biogas production facilitates the use of manure for biogas production. The technology which provides the cheapest CO2 reduction is gasification of waste with the subsequent conversion of gas into transport fuel.

comprehensive representation of models for Energy System analyses insights from the Energy modelling platform for europe emp e 2017
Energy Strategy Reviews, 2018Co-Authors: Berit Müller, Francesco Gardumi, Ludwig HülkAbstract:Abstract This article discusses different approaches that are used to present and categorise models used in Energy System Analysis, with the overall objective to improve their quality, efficiency, and outreach to policy makers and public stakeholders involved in the European Energy transition. A comprehensive literature review identifying strengths and limitations of existing approaches of classification is conducted. It highlights the tendency towards a versatile presentation of models, where the same set of information is available for all users while the way it is presented can be customised according to the background and interests of several stakeholder groups (e.g., modellers, researchers in the Energy field, policy advisers, and policy makers). Online platforms enhance this concept by allowing dynamic adaptations. We think that improving this approach could be a potentially significant contribution to the scientific work in the field of Energy System Analysis. In addition to the literature review, we include experiences from the first meeting of the Energy Modelling Platform for Europe (EMP-E 2017). The participants used different formats to present their models. In the open space provided, the trade-off between simplicity and completeness of representation was visible. Feedback of the meeting showed that gathering European modellers and policy makers in a personal meeting is valuable as it motivates and improves exchange between modelling groups and between modellers and those stakeholders who are interested in specific results.

The German Research Network on Energy Systems Analysis
2018Co-Authors: Christoph Mang, Dominik Most, Carsten Hoyer-klick, Ludwig Hülk, Aron Praktiknjo, Sandra Wassermann, Frieder Borggrefe, Peter Markewitz, Berit Müller, Tom BrownAbstract:In 2015 the German Ministry of Economic Affairs and Energy (BMWi) introduced seven research networks for Energy research. One of them is the Research Network for Energy System Analysis. Aim of this research platform is to strengthen networking between scientists and to increase the transparency and comparability of modelling tools. The research network serves as an open forum for (interdisciplinary) exchange on different questions of Energy System Analysis, forecasting, simulation and medium/long term Energy scenarios. The members cover a wide range of academic institutions, universities, research centers and institutions as well as companies and other organizations. The research network is organized in five working groups. In 2017 the working groups contributed to the 7th Renewable Energies Act of Germany. In addition, a joint three year model comparison experiment is planned to start in 2019 including 38 models and 6 focus subjects. The German Research Network for Energy System Analysis will develop future research topics, new methods and standards. Aiming to improve the interaction within the research community, we seek to establish a stronger link between the national network(s) and the European network for Energy System modelling.
