With the increasing penetration of variable renewable generation, storage is now becoming one of the hottest topics in the utility industry. Research on materials and devices has increased cost-effectiveness, cycle-life and safety. Flywheels, lithium-ion batteries, flow batteries and carbon-enhanced lead‒acid batteries are being deployed. Following small-scale demonstration projects, markets are now gradually taking shape. At the same time, changes in the regulatory framework result in more equitable valuation of storage benefits. The presentation will discuss multi-megawatt applications of a variety of energy-storage technologies. Major recent storage facilities constructed in Texas, California, Pennsylvania and New Mexico under the stimulus program of the American Recovery and Reinvestment Act (ARRA) will be reviewed. As major players begin deploying increasingly more substantial storage projects, operators are recognizing their value for ancillary services. In particular, smoothing and ramping of wind and solar PV are being addressed. Emergency preparedness through storage micro-grids is another important development. There are now over 1200 storage projects listed in the Global Energy Storage Database. With the new California mandate for 1.3 GW of deployment, there is the expectation of an exciting upsurge in storage research and many new projects. Meanwhile, safety considerations are also receiving increasing attention. Storage will make renewables dispatchable and thereby will encourage their deeper penetration. It will also make the grid more resilient, improve asset utilization, and prevent outages.

Biography: Dr. Imre Gyuk, U.S. Department of Energy After taking a B.S. from Fordham University, Dr. Gyuk did graduate work at Brown University on Superconductivity. Having received a Ph.D. in Theoretical Particle Physics from Purdue University he became a Research Associate at Syracuse. As an Assistant Professor he taught Physics, Civil Engineering, and Environmental Architecture at the University of Wisconsin. Dr. Gyuk became an Associate Professor in the Department of Physics at Kuwait University where he became interested in issues of sustainability. Dr. Gyuk joined the Department of Energy to manage the Thermal and Physical Storage program. For the past decade he has directed the Electrical Energy Storage research program in the Office of Electricity which develops a wide portfolio of storage technologies for a broad spectrum of applications. As part of the program he also supervises the $185M ARRA stimulus funding for Grid Scale Energy Storage Demonstrations. He is internationally recognized as an expert on storage technology.
