While energy storage is key to increasing the penetration of variable renewables, near-term effects on greenhouse gas emissions are uncertain. Several studies have shown that operation can increase even if has 100% turnaround efficiency. Furthermore, previous relied national-level data and given very little attention impacts at local scales. This an important omission, as carbon intensities var...

The recent penetration of renewable sources in the energy system caused a transformation of the needs of the distribution system and amplified the need of energy storage systems to properly balance the electricity grid. Among electrochemical energy storage devices, all vanadium flow batteries are those of the most promising technologies due to their high efficiency, long lifetime, reliability a...

This paper focuses on demand management of electricity in consumer groups that form a cooperative. We propose a novel multiagent coordination algorithm to shape the energy consumption of the cooperative in the presence of energy generation and storage. To coordinate individual consumers under incomplete information and optimize the energy storage decision, we decompose the problem to two subpro...

This paper summarizes lessons from an international analysis of the characteristics and field performance of thermal energy storage systems for load management. These systems shift electricity consumed for heating or cooling from high price on-peak periods to lower price off-peak periods. Storage media and system descriptions are reviewed, including a simplified illustration of the economic pri...

We study the economic viability and optimal sizing and siting of a hybrid plant that combines a ringwall hydro storage system with wind and solar power plants (ringwall storage hybrid power plant, RSHPP). A real options model is introduced to analyze the economics of an onshore RSHPP, and in particular of the varying storage volume in light of the stochastic character of wind and solar power, a...

Sustainable future energy scenarios require significant efficiency improvements in both electricity generation and storage. High-temperature solid oxide cells, and in particular carbon dioxide electrolysers, afford chemical storage of available electricity that can both stabilize and extend the utilization of renewables. Here we present a double doping strategy to facilitate CO2 reduction at pe...

Advanced solar thermal electric options are dropping in price and some companies are beginning to introduce thermal storage. This paper suggests not only that Solar Thermal Electricity (STE) has sufficient diurnal and seasonal natural correlation with electricity load to supply the great majority of the US national grid (and by logical extension, those of China and India) on an annual basis wit...

This paper proposes a stochastic dynamic programming framework for the optimal energy management of a smart home with plug-in electric vehicle (PEV) energy storage. This work is motivated by the challenges associated with intermittent renewable energy supplies and the local energy storage opportunity presented by vehicle electrification. This paper seeks to minimize electricity ratepayer cost, ...

Energy storage systems (ESS) have recently become an indispensable solution to many operational issues related to the integration of distributed generation (DG) technologies in electricity grids. Most of the applications are in the form of power quality mitigation and management of the energies between DG and electricity grids. This paper presents a review of the present status of worldwide app...
