Compared to lithium-ion batteries, redox-flow batteries have attracted widespread attention for long-duration, large-scale energy-storage applications. This review focuses on current and future directions to address one of the most significant challenges in energy storage: reducing the cost of redox-flow battery systems. A high priority is developing aqueous systems with low-cost materials and high-solubility redox chemistries. Highly water-soluble inorganic redox couples are important for developing technologies that can provide high energy densities and low-cost storage. There is also great potential to rationally design organic redox molecules and fine-tune their properties for both aqueous and non-aqueous systems. While many new concepts begin to blur the boundary between traditional batteries and redox-flow batteries, breakthroughs in identifying/developing membranes and separators and in controlling side reactions on electrode surfaces also are needed.How much does energy storage cost?The DOE’s Office of Electricity Delivery and Energy Reliability proposed a cost target of $250/kWh to be achieved by 2015, and decreasing to $150/kWh in the future for fully integrated distributed energy-storage systems providing four hours of storage .
What is long duration energy storage (LDEs)?Long Duration Energy Storage (LDES) provides flexibility and reliability in a future decarbonized power system. A variety of mature and nascent LDES technologies hold promise for grid-scale applications, but all face a significant barrier—cost.
Are battery energy-storage technologies necessary for grid-scale energy storage?The rise in renewable energy utilization is increasing demand for battery energy-storage technologies (BESTs). BESTs based on lithium-ion batteries are being developed and deployed. However, this technology alone does not meet all the requirements for grid-scale energy storage.
What is energy storage?Energy storage is a key technology that is becoming more and more important in the energy infrastructure. Currently, approximately 30% of energy consumption is in the transportation sector, and 40% of that use is in the form of electricity .
What is electrical-energy storage & how does it work?Electrical-energy storage is a powerful tool for improving the flexibility of integrating renewable energy into the grid, improving grid reliability, increasing the use of renewable resources, extending the service life of the infrastructure and improving power quality. Rechargeable batteries have many applications.
Why do we need a grid-scale energy-storage system?Under some conditions, excess renewable energy is produced and, without storage, is curtailed 2, 3; under others, demand is greater than generation from renewables. Grid-scale energy-storage (GSES) systems are therefore needed to store excess renewable energy to be released on demand, when power generation is insufficient
