    1. World's First Green Energy Storage Demonstrator

      World's First Green Energy Storage Demonstrator

      The world's first green energy storage demonstrator is now live in the UK and has brought carbon-free fuel, that can be stored or transported for later use, a step closer. The demonstrator project offers a way to decouple the supply of electricity (governed by fluctuating renewables) from the demand (driven by consumer dynamics) and is using renewable electricity to obtain hydrogen from water via electrolysis, nitrogen via air separation, and to power the Haber-Bosch process to make ammonia. Ammonia produced in this way can be a completely carbon-free and practical bulk energy source. Read more at: https://phys.org/news/2018-06-world-green-energy-storage.html#jCp

    3. Magnetically Controlled Battery Could Store Energy for Power Grids

      Magnetically Controlled Battery Could Store Energy for Power Grids

      Scientists have built a battery containing a magnetic fluid that can be moved in any direction by applying a magnetic field. The magnetically controlled battery concept could be especially useful for flow batteries, where it could eliminate the need for the pumps that are typically required for moving the electrolyte from an external storage tank to the inside of a power stack to provide electricity. Flow batteries are being actively researched as large-scale energy storage devices for power grids, where they could store energy captured by intermittent alternative energy sources such as wind and solar.

      NREL Tool Finds Effective Behind-The-Meter Energy Storage Configurations

      The Energy Department's (DOE) National Renewable Energy Laboratory (NREL) has used the Battery Lifetime Analysis and Simulation Tool (BLAST) to confirm that energy storage for demand-charge management can deliver attractive economic benefits. The analysis paired recent utility rate structures with historic data on solar photovoltaic electricity generation and commercial facility loads to evaluate 6,860 unique scenarios. The results revealed that, in the absence of incentives, small battery systems reducing peak demand by 2.5 percent offer the most attractive return on investment.

      Scientists Discover How to Prevent Dendrite Formation in Batteries

      Dendrites-deposits that form on electrode surfaces during the charging process-cause the batteries to short circuit, leading to serious safety hazards. Recently, scientists discovered how to prevent dendrite formation. For the first time, a team including experts at DOE's Pacific Northwest National Laboratory grew protective films around the anodes that prevented dendrites from forming.

      Rubber Meets the Road with New ORNL Carbon, Battery Technologies

      Recycled tires could see new life in lithium-ion batteries that provide power to plug-in electric vehicles and store energy produced by wind and solar, say researchers at Oak Ridge National Laboratory. By modifying the microstructural characteristics of carbon black, a substance recovered from discarded tires, a team led by Parans Paranthaman and Amit Naskar is developing a better anode for lithium-ion batteries. An anode is a negatively charged electrode used as a host for storing lithium during charging.

      New Graphene Framework Bridges Gap Between Traditional Capacitors, Batteries

      Researchers at the California NanoSystems Institute (CNSI) at UCLA have set the stage for a watershed in mobile energy storage by using a special graphene material to significantly boost the energy density of electrochemical capacitors, putting them on a par with lead acid batteries. The material, called a holey graphene framework, has a three-dimensional, perforated structure characterized by tiny holes; it not only increases energy density (the amount of energy stored and ready for use) but allows electrochemical capacitors to maintain their high power density (the amount of power per unit of mass or volume), according to Xiangfeng Duan, a UCLA professor of chemistry and biochemistry who led the research.
