Report Examines Potential of Energy Storage Technologies for Next-Generation Electrical Grid

20.01.2011
A new report released by The Minerals, Metals, & Materials Society (TMS), in support of the U.S. Department of Energy’s (DOE) Office of Electricity Delivery and Energy Reliability and the Advanced Research Projects Agency-Energy (ARPA-E), offers an initial assessment of materials science advances and breakthroughs that could improve performance and lower costs of electrical energy storage (EES) devices for the future electrical grid.

Advanced Materials and Devices for Stationary Electrical Energy Storage Applications documented the findings of a multidisciplinary workshop of materials science experts convened by TMS, in conjunction with Sandia National Laboratories and the Pacific Northwest National Laboratory, last summer.

In addition to TMS members, the workshop drew on the knowledge and expertise from the membership of ASM International, the American Ceramic Society, the Electrochemical Society, and the Materials Research Society.

Making renewable energy, such as wind and solar, a more reliable, cost-effective, and widely utilized source of electricity in the United States is dependent on the development of practical EES technologies that can be deployed at the grid scale.

Renewable energy technologies pose significant challenges for integration into the electrical grid because of their intermittent nature. Electrical energy storage smoothes out this variability—when the wind turbine stops turning or the solar panel has no sun to capture—by providing a means to store energy for back-up power, load shifting, transmission and distribution deferral, and energy arbitrage needs.

Until recently, however, stationary electrical energy storage has been relatively unexplored, with the needs and requirements for optimal performance at the grid level still largely undefined. In addition, most EES technologies currently face significant economic and technical challenges for market entrance.

Both the workshop and resulting report emphasize solutions that could be realistically deployed at the grid scale with DOE involvement in a relatively short time frame—present day through 2030, with particular emphasis on the one-to-five-year and five-to-10 year time blocks. The report provides guidance to the DOE for advancing an array of EES technologies, including advanced lead-acid and lead-carbon batteries; lithium-ion batteries; sodium-based batteries; flow batteries; power technologies such as high-speed flywheels and electrochemical capacitors; and emerging technologies such as metal-air batteries, liquid metal systems, regenerative fuel cells, and advanced compressed-air energy storage.

Recognizing that each storage technology has its own specific limitations and potential solutions, the report also recommends several key advanced materials focus areas that could significantly encourage commercial success across the board.

Basic materials research, for instance, needs to surface more effective, safer, inexpensive, and robust electrochemical materials combinations, as well as explore readily available materials such as iron, aluminum, magnesium, and copper for use in EES technologies. Advanced electrochemical combinations and the more efficient utilization of current electrolytes and electrodes also have the potential to increase conductivity, amplify capacity, reduce resistance, improve thermal tolerance, and extend the life of energy storage devices.

Engineering electrolytes into thin and flexible crystalline solids likewise offer an opportunity to increase efficiency compared to systems with liquid electrolytes. Improved membranes and seals to help limit contamination, novel cell and stack designs for particular stationary applications, and nanomaterials that can lead to development of high-power and quick-response energy storage devices also factor in the report’s recommendations.

The complete report, as well as a summary article and additional background information on the project, can be accessed on the project home page of the TMS Energy website at http://energy.tms.org/initiatives/AMSEES.aspx.

Also available for download is Electric Power Industry Needs for Grid-Scale Storage Applications, the report of a complementary workshop organized by Sandia, with support from TMS, that convened stakeholders from the electric power industry to discuss targets for EES in specific grid applications. This information was used to frame the discussion for the Advanced Materials and Devices for Stationary Electrical Energy Storage Applications report. High resolution images related to both reports are available in the TMS Energy image library at http://energy.tms.org/pressroom.aspx.

About TMS
TMS is a member-driven international professional society dedicated to fostering the exchange of learning and ideas across the entire range of materials science and engineering (MSE), from minerals processing and primary metals production, to basic research and the advanced applications of materials. Of particular interest to TMS and its members through its history has been the role of MSE in addressing both short- and long-term energy challenges. Recently, in response to the needs of both society and the MSE professionals it serves, TMS has committed to an even sharper, more strategic focus on materials-enabled energy technology—TMS Energy. The goals of TMS Energy are to provide leadership, facilitation, and resources that generate and support effective energy solutions based on the innovative development and use of materials. The Advanced Materials and Devices for Stationary Electrical Energy Storage Applications project is one such effort of the TMS Energy initiative. Additional information on TMS Energy can be found at http://energy.tms.org.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
