Energy storage is the key to being able to use renewables viably. One extremely promising approach is the use of highly efficient batteries with capacities in the megawatt region, which are able to quickly compensate shifts in demand.
New storage system: The Supercapattery - New Supercapattery energy storage system with modern power electronics interface for intelligent electricity networks
School of Chemical and Environmental Engineering, University of Nottingham
The Supercapattery has a storage capacity and charging/discharging capacity that lies between those of super capacitors and conventional accumulators.
The aim of the project is to design a new integrated system for storing en-ergy consisting of Supercapattery and power electronics interface. The core materials are chemically modified carbon nanotubes, which are particularly suited to load levelling in electricity networks. The power electronics inter-faces ensure that the current flow is integrated in a stable and high-quality manner. The demonstration of a prototype enables this new system to be re-liably evaluated. The rating relates to the requirements of an operation in an energy storage bank with a high power and energy level and electricity net-work characteristics such as peak load levelling and the independent power control system.

Carbon as an energy storage device - Simple procedure for storing and quickly releasing renewable forms of energy into electricity networks
Center for Applied Energy Research, University of Kentucky
Off-peak energy storage enables demand to be covered at peak times. Electrochemical dual-layer capacitors (EDLCs) offer many benefits: a high power density, low maintenance and long life span.
For over three years an electrochemical cell for the high voltage sector has been developed and researched, which is suitable for storing energy in supply networks with excellent power and energy density. The plan is to study the synthesis, characterisation and evaluation of porous carbons with high energy density for asymmetric EDLCs. Graphite carbons are also being assessed as electrode materials for a new type of electrochemical cell based on lithium-ion. They could achieve an energy density that is three times as high as the current generation of electrochemical capacitors in use.

High voltage in batteries - Highly efficient and reliable block battery energy storage systems

Storing energy reliably is essential for the supply networks with an increasing proportion of volatile generators such as wind energy plants and in weak segments of the network.
The aim of this project is to design and develop a modular battery storage system (BESS) taking into account the interaction between the storage sys-tem and the power electronics. BESS systems allow an extremely short reac-tion time and large amounts of energy, therefore representing another tech-nical method of regulating the network in future. Due to their high energy density and modularity, these systems are easy to integrate with existing networks. High-voltage batteries for direct connection with a direct current (DC) intermediate circuit on an electronic power converter or combined with a DC/DC transformer between two different voltage levels are looked at and analysed in detail. At the end of the project, specifications will be available for an optimal storage system according to ecological and economic criteria.
