1 Trends in energy systems and heat conversion J. Schäfer, M. Metzger, S. Thiem, U. Grumann, and Joachim Bamberger DHC Days 2017: Local to Global Approaches for Innovative District Energy Solutions Unrestricted Siemens

2 Main trends and their impact on the energy system of tomorrow Decarbonization Decentralization Digitalization - Growth in Renewables - Growth in natural gas - Sector coupling - Need for energy storage - Distribution Grid technologies - New ways of design & operating - Condition to connect the real and virtual worlds - To fully integrate all system elements - End customer in the driver seat Increasing Efficiency Page 2

3 Space Sector coupling the idea Systematic analysis and selection of pathways with special regard to fluctuating Renewable Energy Sources Somewhere else A C B here now later Water Gas/Fuel Cold Heat Electricity Generation Utilization Page 3

4 The ESDP model a tool for macro-economic scenario analysis for energy systems, e.g. to evaluate the impact of sector coupling Energy System Development Plan (ESDP) Scenario Definition Fine-Grained Modeling Power Plant Modelling Cell Modelling European Multimodal Market Simulation Operation of centralized power plants Operation of decentralized Cell VPPs Analysis and Evaluation Conversion & Storage Full load hours, economic performance and emissions Int. power exchange Transmission Grid ESDP Portfolio Optimization Power flow simulations TG expansion costs Energy conversion capacities Storage technologies RES Regionalization Operation for all conversion technologies Distribution Grid Annual electric and thermal demand Capacity optimization for technologies Power flow simulations DG expansion costs RES: Renewable Energy Sources VPP: Virtual Power Plant TG: Transmission Grid DG: Distribution Grid Page 4

5 ESDP model for Germany 2050 exemplary results and selected findings Energy Flows in Germany 2050 Biomass origins Electricity High temp. heat Diesel processing & trucks Low temp. heat H2 for chem. processes & cars Selected findings for Germany in 2050 / trends in heat conversion & storage Power-to-heat (P2H) can be remarkably cost efficient way of sector coupling and decarbonization (but regulation needs to be adapted) P2H at CHP sites (district-heating) can reduce variable system costs significantly P2H at CHP sites (district-heating) can reduce curtailment of renewables considerably P2H at CHP sites (district-heating) ideally comprises a heat pump, electrode boilers, and/or a thermal energy storage Trend towards decarbonization is a chance for district heating network operators!
