The European Union (EU) aims to transform its energy system into a lowcarbon, sustainable and resource efficient system. The proposed transformation implies huge changes and would require the reinvention of entire sectors of the economy. The EU’s energy policy package, however, focuses on technological changes (how energy is produced) rather than functional changes (what the energy is being used for). Looking at energy from a functional perspective, intermittent renewable energy needs to be paired with storage to be able to provide the same services as current fossil fueled power plants. In this case study, we look at the implications of storage requirements in a 100% intermittent electricity system in Spain and Germany.
