READ MOREEnergy storage technologies with longer durations of 10 to 100 h could enable a grid with more renewable power, if the appropriate cost structure and performance—capital costs for power and energy, round-trip efficiency, self-discharge, etc.—can be realized. Although current technologies such as lithium-ion batteries are
READ MOREWe observe that economic incentives for houses to store energy depend deeply on the implemented pricing mechanism and on the homogeneity in the houses'' characteristics. Furthermore, when prices are based on the consumption of the eco-neighborhood, storage appears as a compensation for the errors made by the service

READ MOREDOI 10.3386/w22752. Issue Date October 2016. The increasing importance of intermittent renewable energy sources suggests a growing importance for energy storage as a way of smoothing the variable output. In this paper I investigate factors affecting the amount of energy storage needed, including the degree of intermittency
READ MOREThe global energy market is in turmoil. Volatility in oil prices, mounting energy security fears and the looming catastrophe of climate change show that our current energy system poses grave threats to our way of life, at the same time as making it possible. Against this backdrop, the seemingly simple idea of storing
