Electricity storage for intermittent renewable sources

Electricity storage for intermittent renewable sources

With sufficient electricity storage capacity, any power production profile may be mapped onto any desired supply profile. We present a framework to determine the required storage power as a function of time for any power production profile, supply profile, and targeted system efficiency, given the loss characteristics of the storage system. We apply the framework to the electrochemical storage ...

Non-renewable and intermittent renewable energy sources: friends and foes?

Promotion Systems for Electricity Generation from Renewable Energy Sources Revisited

To increase the share of electricity from renewable energy sources (RES-E) different strategies are implemented in various countries. The core objective of this paper is to extract lessons learned from promotion schemes in Europe and to derive resulting recommendations for future. The major results are: (i) The success stories of RES-E in Europe in recent years has been triggered by FITs; A wel...

Energy Storage Technologies for Utility Scale Intermittent Renewable Energy Systems

In current conventional utility systems, fossil fuel or nuclear power plants must back up intermittent renewable electricity generators if the utility grid is to have acceptable reliability. For low levels of intermittent power, this can be achieved without difficulty or added expense. For high levels this reliance on other generators becomes explicit and increasingly expensive, and transmissio...
