Why Energy Storage? 10
Why energy storage? Worldwide renewable and non-renewable power capacity additions The global trend is towards much more PV and wind Source: IRENA (2017), REthinking Energy 2017: Accelerating the global energy transformation. International Renewable Energy Agency, Abu Dhabi . 11
Why energy storage? With wind and solar, new power system will be based on two technologies that completely change the picture Gross electricity generation of Electricity generation and consumption renewable energies 2000 - 2035 in a sample week 2023 G Specific W characteristics of Wind and Solar PV 1 Variable High 2 capital costs Very low 3 variable cost AGEB (2015a), BNetzA (2014), BNetzA (2015b), own Fraunhofer IWES (2013) calculations 12
Why energy storage? Flexibility is the paradigm of the new power system – baseload capacities are hardly needed in longer future => New coal power plants need to get flexible! Electricity generation and consumption in a sample week with 50% RES share Key flexibility options Flexible fossil and bioenergy power plants (incl. CHP) Grids and transmission capacities for exports/imports Demand Side Management Storage technologies (Batteries, Power-to-Gas) Integration of the power, heat and transport sectors (power-to-heat, electric cars) Own calculations on basis of Agora Energiewende (2015b) Source: AGORA Dr. Patrick Graichen; Insights from Germany’s Energiewende, Berlin 2016 13

Why energy storage? Future of energy systems – towards a new paradigm? Smart local grids, linking a diverse set of distributed resources across different sectors. Why energy storage? • increased distributed energy resources increases grid variability. • Baseload capacities needed for grid flexibility. sustainable solution to emerging energy problems! 15
