EPA Green Chemistry Challenge Winners

Posted: 08-13-19

Prof. Sanjoy Banerjee of City College of New York and City University of New York Energy Institute, Sandia National Laboratories, Urban Electric Power, Inc., Brookhaven National Laboratory, and the Department of Energy Office of Electricity, Energy Storage Research Program won the 2019 US Environmental Protection Agency Green Chemistry Challenge Award in the Academic category. The team was recognized for creating large-scale zinc-manganese oxide batteries that can be recharged thousands of times without the typical decrease in the length of the battery’s life-time. These batteries do not have some of the limitations of lithium-ion and lead-acid batteries, and they use materials that are abundant and common in existing supply chains. Sandians Tim Lambert, Mathew Lim, Igor Kolesnichenko, and Babu Chalamala, along with Prof. Igor Vasiliev from New Mexico State University were also involved in this research project.

Posted: 09-08-15

The Oregon Dept. of Energy is partnering with the U.S. DOE Office of Electricity’s Energy Storage Program, and Sandia National Laboratories, to offer funds for an energy storage demonstration project in Oregon. Up to $250,000 in federal funds will be matched by up to $45,000 in state funds from ODOE and Oregon BEST.
The deadline for submitting proposals is Oct. 16, and the award is expected to be announced Nov. 2.
The demonstration aims to enable installation and continuous operation of an electrical energy storage system, or ESS, with a capacity of 500kW/500kWh or greater, connected to the transmission or distribution system. No preference is given to one energy storage technology over others; however, preference will be given to projects that demonstrate two or more of the following five high-interest applications, or “use cases:”

  1. T&D upgrade deferral/management of peak demand
  2. Service reliability/resiliency
  3. Power quality/voltage support
  4. Grid regulation
  5. Renewable energy firming, ramp control, energy shift

Proposals are encouraged from utilities, energy storage technology vendors, energy service suppliers and electric customers including, but not limited to, municipalities, universities, and commercial and industrial businesses. Applicants that are not electric utilities must have a committed utility partner or include a letter of support from the interconnecting utility. A minimum cost share of 50 percent is required. ODOE prefers projects that can be interconnected to the electric transmission or distribution system within 18 months of the award and the project must operate for a minimum of one full year.

DOE OE Energy Storage Safety Strategic Plan Released

Posted: 12-10-14

The Dept. of Energy’s Office of Electricity Delivery and Energy Reliability Energy Storage Program has announced their release of the Energy Storage Safety Strategic Plan (PDF, 685 kb) to standardize the validation of the safety of grid-scale electrical energy storage projects.

The Strategic Plan addresses the key area of validated energy storage safety, spanning grid-scale, utility, communal, and residential deployments for the increasing array of energy storage technologies. It highlights the key areas of validation techniques, incident preparedness, and safety documentation, and recommends near- and long-term actions to address these needs.

Dr. Imre Gyuk, director of DOE OE and Energy Reliability Energy Storage Program, says, “We want energy storage to reach full acceptance as a component of the electric grid. For this to happen, a number of things must occur: technical feasibility of our technologies, competitive costs and established value, a regulatory framework, and safety. If we don’t have validated safety, we don’t have a product.”

Energy Storage Test Pad Characterizes TransPower’s GridSaver

Posted: 11-03-14

Sandia National Laboratories has begun characterizing the capacity, power, safety and reliability of TransPower’s GridSaver, a 1 megawatt, lithium-ion grid energy storage system, at Sandia’s Energy Storage Test Pad.

Project lead David Rosewater said, “Independent evaluations provide valuable feedback for industry efforts to standardize metrics for characterizing and reporting reliability, safety and performance. Companies need the standards to develop large procurement goals for grid energy storage because they must be able to compare performance and cost.”

Sandia’s Energy Storage Test Pad and Energy Storage Analysis Laboratory test facilities validate manufacturers’ specifications of energy storage devices through characterization and application-specific cycle testing. They also can help users evaluate system parameters, including storage device efficiency, performance to specifications, reliability and balance of plant operation.

A Sandia Labs News Release provides more information on the TransPower GridSaver characterization testing.

NV Energy Electricity Storage Valuation Study Released

Posted: 06-28-13

Sandia National Laboratories’ Electric Power Systems Research Dept. and Pacific Northwest National Laboratory’s Advanced Power and Energy Systems Group have released a jointly authored report that examines how grid-level electricity storage might benefit the operations of NV Energy in 2020, and assesses whether those benefits justify the cost of the storage system.

Titled “NV Energy Electricity Storage Valuation” (PDF, 933 kb), the report finds that grid-level storage adds the most value to the 2020 NV Energy system by providing regulating reserve, and that a grid-level storage facility in the 2020 NV Energy system may have a positive net present value at today’s storage system prices, provided that regulating reserve from a fast ramp rate resource is valued more than that from a slow ramp rate resource.
