This study presents a novel energy system modelling approach for the analysis and comparison of global transition pathways decarbonisation electricity sector. The results International Energy Agency (IEA), Teske/DLR scenarios are each reproduced. Additionally, five new trajectories, called LUT, presented. research examines feasibility scenario across nine major regions in 5-year intervals, from 2015 to 2050, under uniform environment with identical technical financial assumptions. main...
The Energy [R]evolution 2010 scenario is an update of the scenarios published in 2007 and 2008. It takes up recent trends global energy demand production analyses to which extent this affects chances for achieving climate protection targets. main target reduce CO2 emissions 3.7 Gt/a 2050, thus limiting average temperature increase below 2°C preventing dangerous anthropogenic interference with system. A ten-region system model used simulating supply strategies. review sector region specific...
We present the first comprehensive estimate of final energy demand for heat in all EU28 member states reference year 2012, differentiated by temperature levels, comparing two different approaches. Two calculation approaches based on data sets yielded estimates total 8150 PJ and 8518 respectively. Approach 1 distinguishes between three process (PH) levels results <100°C: 2077 PJ, 100–400°C: 2214 >400°C: 3859 PJ. The second approach low space hot water (<100°C: 1161 PJ) four PH with a...
CO2 emissions from global steel production may jeopardize climate goals of 1.5 °C unless current practices will be rapidly decarbonized. At present, primary iron and is still heavily dependent on fossil fuels, primarily coke. This study aims to determine which decarbonization pathways can achieve the strongest emission reductions industry in Germany by 2050. Moreover, we estimate whether German able stay within its sectoral carbon budgets for a or 1.75 target. We developed three scenarios...
With its abundance of renewable energy potentials, not only for hydropower and bioenergy, but also wind solar, Brazil provides good prospects a carbon neutral system. The role an enhanced coupling the power, heat transport sectors in such systems is yet fully understood. This paper analyses least-cost composition operation power supply system as part Brazil. It relies on application high-resolution model REMix. Our analysis reveals that expansion solar more cost-efficient than construction...
It is still possible to comply with the Paris Climate Agreement maintain a global temperature ‘well below +2.0 °C’ above pre-industrial levels. We present two non-overshoot pathways (+2.0 °C and +1.5 °C) regional decarbonization targets for four primary energy sectors—power, heating, transportation, industry—in 5-year steps 2050. use normative scenarios illustrate effects of efficiency measures renewable use, describe roles increased electrification final demand synthetic fuels, quantify...
Abstract Germany 2050: For the first time reached a balance between its sources of anthropogenic CO 2 to atmosphere and newly created sinks. This backcasting study presents fictional future in which this goal was achieved by avoiding (∼645 Mt ), reducing (∼50 ) removing (∼60 carbon emissions. meant substantial transformation energy system, increasing efficiency, sector coupling, electrification, storage solutions including synthetic carriers, sector‐specific for industry, transport,...
A multitude of pathways for decarbonizing energy systems have been formulated. In the development these scenarios, focus is often only on system costs at a given CO2 emission reduction. However, when assessing sustainability in broader sense, many more aspects need to be considered: addition greenhouse gas emissions, induce further environmental and socio-economic impacts must meet requirements security supply cost efficiency. For compatibility future with concepts, alternative compared...
Sustainable development embraces a broad spectrum of social, economic and ecological aspects. Thus, sustainable transformation process energy systems is inevitably multidimensional needs to go beyond climate impact cost considerations. An approach for an integrated interdisciplinary sustainability assessment system pathways presented here. It first integrates modeling with that focuses on life cycle-based environmental macroeconomic impacts. Then, stakeholders’ preferences respect defined...
The scenario analysis focuses on two metropolitan regions of eastern China which are characterized by high energy consumption and related CO2 emissions. Current policies rather short-term driven weak regarding sectoral coupling regional integration. As in economic activities population the one hand renewable resources other have a very imbalanced distribution, long-term integrated system modelling needs to consider specific challenges efficiency improvement, coal reduction, transport...
Today, transportation contributes significantly to greenhouse gas emissions and air pollution. However, new technologies are emerging existing being further improved. This article presents the results of a comprehensive study on development drive-trains, resulting electricity fuel consumption as well CO2 selected pollutants in land transport Germany. includes quantitative assessment technological potentials energy emissions. The scenario building followed an explorative approach. Only...
Newly industrialized countries face major challenges to comply with the Paris Treaty targets as economic growth and prosperity lead increasing energy demand. Our paper analyses technological structural options in terms of efficiency renewable energies for a massive reduction energy-related CO2 emissions Latin America. Brazil Mexico share similar prospects but differ significantly respect potentials. We identify, how this leads different transformation pathways. By applying an system...
We present an energy transition pathway constrained by a total CO2 budget of 7 Gt allocated to the German system after 2020, Budget Scenario (BS). apply normative backcasting approach for scenario building based on historical data and assumptions from existing studies. The modeling combines comprehensive model (ESM) with REMix—a cost optimization power heat that explicitly incorporates sector coupling. To achieve necessary reduction, focuses electrifying all end use sectors until 2030,...
Abstract Background Given the multitude of scenarios on future our energy systems, multi-criteria assessments are increasingly called for to analyze and assess desired undesired effects possible pathways with regard their environmental, economic social sustainability. Existing studies apply elaborate lists sustainability indicators, yet these indicators defined selected by experts relative importance each indicator overall is either determined or computed using mathematical functions. Target...
Apparent electrical conductivity (ECa) of soils can be measured easily by nondestructive methods and, therefore, could useful in the mapping soil properties, which influence ECa. The influences structure, bulk density, clay and water content, EC solution, cation exchange capacity (CEC) on ECa were examined laboratory experiments for 19 at 16 to 18 contents. Soil structure increased variability but had no other influence. Bulk density also when variables used a volume basis rather than weight...
In order to analyse long-term transformation pathways, energy system models generally focus on economical and technical characteristics. However, these usually do not consider sustainability aspects such as environmental impacts. contrast, life cycle assessment enables an extensive estimate of those Due complementary characteristics, the combination thus allows comprehensive assessments technically economically feasible pathways. We introduce FRITS, a FRamework for Impacts Transformation...
In the development of climate-friendly energy system transformation strategies it is often ignored that environmental protection encompasses more than climate alone. There therefore a risk developing whose friendliness comes at expense higher other impacts. Consequently, an assessment impacts required if undesired side effects are to be avoided and developed both environmentally friendly. this paper, ten structurally different for German were re-modeled (in harmonized manner). Five these...

To evaluate their sustainability, it is necessary to analyze macroeconomic and distributional effects. An approach do this analysis an integrated consistent framework presented here. Methods Comparing ten transition scenarios with emission reduction targets by 2050 of 80% or 95%, respectively, allows evaluating a broad range transformation respect future technology carrier mix.
