The current policy target to reduce GHG emissions in Germany by 80–95% by 2050 stabilizes global warming at 2 ° C. For the more ambitious limitation of 1.5 ° C, these targets need to be adjusted urgently. In 2015, the share of renewable energies in primary energy consumption in Germany was just 12.6%. This paper develops four main scenarios to limit the temperature rise to 1.5 ° C. The integrated energy system model LEAP was used to estimate the energy balances and the climate mitigation targets. The results of the model suggest that GHG emission drops to 9.2 Mt of CO2e in the COP21 Paris Scenario compared to 20.3 Mt of CO2e in the Reference Scenario. In addition to the BAU and COP21 Paris Scenarios, an Energy Efficiency and a 100% Renewable Scenario are analyzed as well. On the other hand, the GHG emission mitigation costs in the COP21 Paris Scenario are 194.2 € / t of CO2e, the highest amongst all scenarios considered. The present work shows that it seems possible for Germany to achieve the Paris agreement targets if an integrated approach is applied to the country's energy sector.","PeriodicalId":147306,"journal":{"name":"2018 7th International Energy and Sustainability Conference (IESC)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125365905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective is to provide domestic electricity with a high rate of availability and stabilized voltage at a target price of approximately 1000 US-Dollars. As no ready-made systems are available that meet the demands, an own approach is developed. Ready-made components are used and an Arduino microcontroller with a self-developed charging algorithm is added to control appropriate charging from the grid. The system is dimensioned and verified in simulations and implemented into a pilot plant in Gummersbach, Germany. While further testing and bug fixing is needed - the basic functionality works. A cost calculation based on VDI 2067, using German net prices, shows the exceedance of the target price for investment as well as high annual cost. This is mainly caused by the high cost of the battery system, which derive from the operating life that is chosen in accordance with the simulated battery cycles and manufacturer data on cycle stability.","PeriodicalId":147306,"journal":{"name":"2018 7th International Energy and Sustainability Conference (IESC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133567266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PVT-modules produce thermal and electrical energy at the same time. Since the efficiency of a photovoltaic module decreases with increasing temperature, the temperature of the heat transfer media is often limited to about 30°C and the PVT-module is combined with a heat pump, which increases the temperature on the “warm side”. A common approach is to integrate the PVT-module directly as an evaporator in a heat pump system (PVT-direct).This paper presents the development of a control strategy for a PVT-based CO2 heat pump that takes into account solar radiation, ambient temperature, wind speed, evaporator temperature and compressor power. The developed control strategy provides different operating modes depending on the solar radiation supply as well as the ambient temperature.","PeriodicalId":147306,"journal":{"name":"2018 7th International Energy and Sustainability Conference (IESC)","volume":"689 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132225613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, many purification tank for rainwater (PTR) have to be built in areas with separate sewers for rainwater and wastewater. The heavy polluted rainwater has to be transmitted over the wastewater treatment plant. The wastewater treatment plant and sewer are constructed only for the past wastewater quantities. Aggravatingly the inflow is added. For this reason, the wastewater treatment plant and sewer are strongly working close by full capacity during rain events. The additional wastewater caused by PBR can lead to an overload of the wastewater treatment plant sewer. This has the consequence of unsettled wastewater in nature. The goal of pollution reduction in flowing waters would be merged thereby. In this case, PTRs have to be controlled centrally. If enough capacity in the wastewater treatment plant and sewer is available each PTR by each PTR could be pumped dry. For this control application a PTR-controller is developed. The controller is tested in simulation tool simba#water. Thereby the operability of the PTR-controller and the discharge for sewer and wastewater treatment plant could be verified.","PeriodicalId":147306,"journal":{"name":"2018 7th International Energy and Sustainability Conference (IESC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128244341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
