Abstract
With the ongoing energy transition in Europe, the share of variable renewable energies (vRE) in the power system increases steadily and different flexibility options gain importance. This work investigates the deployment of supply side flexibility options in the future European power system. We use a cost-minimising energy system model that endogenously optimises the energy-to-power (E2P) ratio and particularly focus on lithium-ion batteries, vanadium redox flow batteries, adiabatic compressed air energy storage and hydrogen storage. We explore the competition of these flexibility options across a broad defossilisation spectrum. Starting at vRE shares of around 50%, we find non-linearly increasing storage requirements and observe a leap when approaching a zero-emission system, which is mainly driven by hydrogen storage investments. We also find that lithium-ion batteries with E2P ratios between 2 and 6 hours are particularly deployed in countries with high levels of solar power, whereas hydrogen storage with E2P ratios between 300 and 1000 hours is mainly deployed in countries with high levels of wind power. Adiabatic compressed air energy storage with E2P ratios between 15 and 20 hours are only deployed in a completely defossilised system. In addition, we analyse storage operating requirements including operating hours and ramp rates for different defossilisation levels.
