    1. Cheaper Battery Technology for Solar Storage

      Cheaper Battery Technology for Solar Storage

      Researchers at WMG, University of Warwick have formed a new research partnership with battery technology innovators Faradion, and smart energy storage specialists Moixa Technology, to develop sodium-ion cells as a significantly lower cost alternative to lithium-ion batteries for solar energy storage. This collaboration is being part funded by Innovate UK, the UK's innovation agency.   A significant proportion of the cost of current solar energy storage systems comes from the commonly used lithium-ion battery. However by using highly abundant sodium salts rather than lithium, Sodium-ion cells are anticipated to be 30% cheaper to produce. This makes solar storage more accessible and opening up the possibility of domestic renewable energy storage to a greater number of households and businesses worldwide. Developments in this area could lead to a CO2 reduction of 500,000 tonnes each year.

      Iowa State, Ames Laboratory Engineer Awarded $3 Million for Battery Study

      While lithium-ion batteries have proven their worth in storing energy on a smaller scale, Steve W. Martin says an alternative solution is necessary for storing large amounts of energy, like the gigawatts of wind energy now being harvested from Iowa’s farmland. That’s why Martin, an Anson Marston Distinguished Professor in materials science and engineering and an associate of the U.S. Department of Energy’s Ames Laboratory, and his research team at Iowa State University have teamed up with collaborators at the University of Houston, the University of Colorado Boulder, Washington State University and Solid Power Inc., a small battery company, to develop an all-solid-state sodium battery.

      View of an Energy Storage System

      All customers want reliable power but for some it’s truly a necessity. For one of PG&E’s customers, a company conducting sensitive research work, any interruption in power could cause significant losses in both experimental data and personnel time. S&C’s Yerba Buena project—a finalist for the 2015 Energy Storage North America Awards – provided a solution.

    4. New Lithium-Sulfur Battery With Cycle Performance Comparable To That Of Lithium-Ion Batteries & Double The Energy Density

      New Lithium-Sulfur Battery With Cycle Performance Comparable To That Of Lithium-Ion Batteries & Double The Energy Density

      A new lithium-sulfur battery that demonstrates cycle performance that’s comparable to that offered by currently available commercial lithium-ion batteries and possesses roughly twice the energy density has been developed by an international team of researchers from South Korea and Italy. This research team — which was led by researchers from Hanyang University — utilized a highly reversible dual-type sulfur cathode (solid sulfur electrode and polysulfide catholyte) and a lithiated Si/SiOx nanosphere anode, in order to achieve its new results.

      Liquid Metal Alloy Electrode Boosts Potential of Sodium-Beta Batteries

      A new battery electrode designed at the Pacific Northwest National Laboratory (PNNL) combines liquid-state cesium and sodium to dramatically improve on the efficiency, safety and useful life of sodium-beta batteries (NBBs). If the technology is scaled up successfully, the advance could help build a smart electric grid that makes better use of renewables, such as solar and wind.

    6. Researchers Testing Expanded Graphite Anode For Sodium-Ion Batteries

      Researchers Testing Expanded Graphite Anode For Sodium-Ion Batteries

      Most of us are familiar with graphite as the stuff pencils are filled with, but it has another use as anodes in lithium-ion batteries. Alas, lithium-ion batteries are expensive, and cheaper alternatives like sodium-ion batteries can’t use regular graphite anodes. Researchers at the University of Maryland have developed an expanded graphite anode that could make cheaper sodium-ion batteries commercially viable. It all centers on the larger sodium-ions, which can’t penetrate the graphite anode as well as the smaller lithium-ions. The result is a low charge capacity, making sodium-ion batteries with standard graphite anodes impractical to use.

      Scientists Examine New Material With Potential Use in Batteries

      Analysis of a manganese-based crystal by scientists at the National Institute of Standards and Technology (NIST) and the Massachusetts Institute of Technology (MIT) has produced the first clear picture of its molecular structure. The findings could help explain the magnetic and electronic behavior of the whole family of crystals, many of which have potential for use in batteries.

      The Yerba Buena Battery Energy Storage System Pilot Project charges batteries when demand is low and then sends reserved power to the grid when demand grows. The system has the potential to provide important services for balancing energy supply and demand, helping to support greater integration of intermittent renewable generation, as well as improving power quality and reliability for customers.

      Better batteries could revolutionize solar, wind power (good overview)

      Batteries are key. They can directly power electric cars and buses and, indirectly, homes and big buildings by storing solar and wind power for times when the sun doesn't shine and the wind doesn't blow. They balance out renewables that produce energy intermittently so consumers can power up laptops or run refrigerators 24/7.

      Report: (Installed) Batteries for Utility-Scale Applications in Asia Pacific Will Surpass 25GW by 2022

      Sodium sulfur batteries constitute the largest number of deployed storage projects in the region. While advanced batteries are staged to play a large role in the development of power sectors across Asia Pacific, bulk energy storage technologies, such as pumped hydro, will continue to play an important role in emerging markets like China.

    11. Energy storage issue highlighted (Re: Stanford study - cost of ownership)

      Energy storage issue highlighted (Re: Stanford study - cost of ownership)

      (Stanford researchers) ... worked out the cost of both building the (storage) technology and maintaining it over a 30-year timescale ... to minimise replacement costs. They derived the “energy stored on investment” for each of the seven technologies to work out how much more energy it could store over its lifetime than it took to build and maintain.

      NOTE: This presents one aspect of the Stanford Univ. study reported here.
