Electricity Storage and the Renewable Energy Transition
Introduction. The transition to renewable energy sources is a main strategy for deep decarbonization. In many countries, the potentials of dispatchable renewables—such as hydro power, geothermal, or bioenergy—are limited. The renewable energy transition is thus often driven by wind power and solar photovoltaics (PVs).
