--- _id: '43464' abstract: - lang: eng text: Lightweight design is a common approach to reduce energy demand in the use stage of vehicles. The production of lightweight materials is usually associated with an increase in energy demand, so the environmental impacts of lightweight structures need to be assessed holistically using a life cycle assessment. To estimate the life cycle environmental impacts of a product in its developmental stage, for example, by life cycle engineering, future changes in relevant influencing factors must be considered. Prospective life cycle assessment provides methods for integrating future scenarios into life cycle assessment studies. However, approaches for integrating prospective life cycle assessment into product development are limited. The objective of this work is to provide the methodological foundation for integrating future scenarios of relevant influencing factors in the development of lightweight structures. The applicability of the novel methodology is demonstrated by a case study of a structural component in a steel, aluminium, and hybrid design. The results show that appropriate decarbonisation measures can reduce the life cycle greenhouse gas emissions by up to 95 percent until 2050. We also found that shifts in the environmentally optimal design are possible in future scenarios. Therefore, the methodology and data provided contribute to improved decision-making in product development. article_number: '3371' author: - first_name: Moritz full_name: Ostermann, Moritz id: '44763' last_name: Ostermann orcid: https://orcid.org/0000-0003-1146-0443 - first_name: Julian full_name: Grenz, Julian last_name: Grenz - first_name: Marcel full_name: Triebus, Marcel id: '66036' last_name: Triebus - first_name: Felipe full_name: Cerdas, Felipe last_name: Cerdas - first_name: Thorsten full_name: Marten, Thorsten id: '338' last_name: Marten - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster - first_name: Christoph full_name: Herrmann, Christoph last_name: Herrmann citation: ama: 'Ostermann M, Grenz J, Triebus M, et al.

For an efficient use of solar and wind energy in an energy system, correct design and sizing of a power system is of high importance and improving or optimizing the process of data obtaining for this purpose leads to higher performance and lower cost per unit of energy. It is essential to have the most precise possible estimation of solar and wind energy potential and other local weather parameters in order to fully feed the demand and avoid extra costs. There are various methods for obtaining local data, such as local measurements, official organizational data, satellite obtained, and reanalysis data. In this paper, the Modern-Era Retrospective analysis for Research and Applications dataset version 2 (MERRA-2) dataset provided by NASA is introduced and its performance is evaluated by comparison to various locally measured datasets offered by meteorological institutions such as Meteonorm and Deutscher Wetterdienst (DWD, or Germany’s National Meteorological Service) around the world. After comparison, correlation coefficients from 0.95 to 0.99 are observed for monthly global horizontal irradiance values. In the case of air temperature, correlation coefficients of 0.99 and for wind speed from 0.81 to 0.99 are observed. High correlation with ground measurements and relatively low errors are confirmed, especially for irradiance and temperature values, that makes MERRA-2 a valuable dataset, considering its world coverage and availability. article_number: '882' article_type: original author: - first_name: Arash full_name: Khatibi, Arash id: '43538' last_name: Khatibi - first_name: Stefan full_name: Krauter, Stefan id: '28836' last_name: Krauter orcid: 0000-0002-3594-260X citation: ama: Khatibi A, Krauter S.

Existing insight-based integration methods refer to the idealised Grand Composite Curve requiring the full exploitation of heat recovery potential but leave the question of how to deal with technical or economic limitations unanswered. In this work, a novel Heat Pump Bridge Analysis (HPBA) is introduced for practically targeting technical and economic heat pump potential by applying Coefficient of Performance curves into the Modified Energy Transfer Diagram (METD). Removing cross-Pinch violations and operating heat exchangers at minimum approach temperatures by combined application of Bridge Analysis increases the heat recovery rate and reduce the temperature lift to be pumped at the same time. The insight-based METD allows the individual matching of heat surpluses and deficits of individual streams with the capabilities and performance of different market-available heat pump concepts. For an illustrative example, the presented modifications based on HPBA increase the economically viable share of the technical heat pump potential from 61% to 79%. article_number: '137' author: - first_name: Florian full_name: Schlosser, Florian last_name: Schlosser - first_name: Heinrich full_name: Wiebe, Heinrich last_name: Wiebe - first_name: Timothy G. full_name: Walmsley, Timothy G. last_name: Walmsley - first_name: Martin J. full_name: Atkins, Martin J. last_name: Atkins - first_name: Michael R.

The performance of cooling systems depends on their part-load performance and their condensing temperature, which are often not continuously measured. Recorded energy data remain unused, and manufacturers’ data differ from the real performance. For this purpose, manufacturer and real data are combined and continuously adapted to form part-load chiller models. This study applied a predictive optimization algorithm to calculate the optimal operating conditions of multiple chillers. A sprinkler tank offers the opportunity to store cold-water for later utilization. This potential is used to show the load shifting potential of the cooling system by using a variable electricity price as an input variable to the optimization. The set points from the optimization have been continuously adjusted throughout a dynamic simulation. A case study of a plastic processing company evaluates different scenarios against the status quo. Applying an optimal chiller sequencing and charging strategy of a sprinkler tank leads to electrical energy savings of up to 43%. Purchasing electricity on the EPEX SPOT market leads to additional costs savings of up to 17%. The total energy savings highly depend on the weather conditions and the prediction horizon. article_number: '1926' author: - first_name: Ron-Hendrik full_name: Peesel, Ron-Hendrik last_name: Peesel - first_name: Florian full_name: Schlosser, Florian last_name: Schlosser - first_name: Henning full_name: Meschede, Henning last_name: Meschede - first_name: Heiko full_name: Dunkelberg, Heiko last_name: Dunkelberg - first_name: Timothy full_name: Walmsley, Timothy last_name: Walmsley citation: ama: Peesel R-H, Schlosser F, Meschede H, Dunkelberg H, Walmsley T.

However, sizing based on one representative time series, not considering the variability of process streams due to their discontinuous operation, often leads to oversizing. The sensitive evaluation of the performance of an HRL by Monte Carlo (MC) simulation requires sufficient historical data and performance models. Stochastic time series are generated by distribution functions of measured data. With these inputs, one can then model and reliably assess the benefits of installing a new HRL. A key element of the HRL is a stratified heat storage tank. Validation tests of a stratified tank (ST) showed sufficient accuracy with acceptable simulation time for the variable layer height (VLH) multi-node (MN) modelling approach. The results of the MC simulation of the HRL system show only minor yield losses in terms of heat recovery rate (HRR) for smaller tanks. In this way, costs due to oversizing equipment can be reduced by better understanding the energy-capital trade-off. article_number: '930' author: - first_name: Florian full_name: Schlosser, Florian id: '88614' last_name: Schlosser - first_name: Ron-Hendrik full_name: Peesel, Ron-Hendrik last_name: Peesel - first_name: Henning full_name: Meschede, Henning last_name: Meschede - first_name: Matthias full_name: Philipp, Matthias last_name: Philipp - first_name: Timothy full_name: Walmsley, Timothy last_name: Walmsley - first_name: Michael full_name: Walmsley, Michael last_name: Walmsley - first_name: Martin full_name: Atkins, Martin last_name: Atkins citation: ama: Schlosser F, Peesel R-H, Meschede H, et al.

At the same time, a fluctuating and decentralised supply of energy, especially at lower voltage levels, leads to a local discrepancy in the power balance between generation and consumption. A possible solution in connection with demand side management is the grid-oriented flexibilisation of energy demand. The present study shows how the use of an innovative hybrid-redundant high-temperature heat system (combined heat and power (CHP), power-to-heat system (PtH), gas boiler) can contribute to a flexibilisation of the electrical energy demand of plastics processing companies. In this context, the flexibilisation potential of a company is to be understood as the grid-related change of the energy supply through a change of the energy sources within the framework of the process heat supply. For this purpose, an omniscient control algorithm is developed that specifies the schedule of the individual system components. A sensitivity analysis is used to test the functionality of the control algorithm. Determination of the electrical flexibilisation potential is carried out via a comprehensive simulation study using Monte Carlo methods. For this purpose, the residual load curves of four characteristic distribution grids with a high share of renewable energies as well as heat load profiles of injection moulding machines are taken into consideration. A frequency distribution provides information on the electrical flexibilisation potential to be expected depending on the various combinations. The evaluation is carried out using a specially introduced logic, which identifies grid-relevant changes in the company's power consumption as flexibilisation potential based on a reference load curve. The results show that a reliable energy supply for production is possible despite flexibilisation. Depending on the grid under consideration, there are differences in the exploitation of the potential, which essentially depends on the installed renewable capacity. Depending on the scenario under consideration, an average of up to 1486 kWhel can be shifted in a positive direction and 1199 kWhel in a negative direction. article_number: '711' author: - first_name: Heiko full_name: Dunkelberg, Heiko last_name: Dunkelberg - first_name: Maximilian full_name: Sondermann, Maximilian last_name: Sondermann - first_name: Henning full_name: Meschede, Henning id: '86954' last_name: Meschede - first_name: Jens full_name: Hesselbach, Jens last_name: Hesselbach citation: ama: Dunkelberg H, Sondermann M, Meschede H, Hesselbach J.
