    1. New Type of Electrolyte Could Enhance Supercapacitor Performance

      New Type of Electrolyte Could Enhance Supercapacitor Performance

      Supercapacitors, electrical devices that store and release energy, need a layer of electrolyte — an electrically conductive material that can be solid, liquid, or somewhere in between. Now, researchers at MIT and several other institutions have developed a novel class of liquids that may open up new possibilities for improving the efficiency and stability of such devices while reducing their flammability.

    2. Ultracapacitors On UC San Diego's Microgrid — Smoothing the Sun

      Ultracapacitors On UC San Diego's Microgrid — Smoothing the Sun

      Maxwell Technologies has installed the first ultracapacitor energy storage system on UC San Diego’s microgrid. The system, an inconspicuous 20-foot container filled with ultracapacitor modules, supports the solar panels that capture and feed energy to the adjacent La Jolla Playhouse Theater. The goal of the Maxwell ultracapacitor bank installation was to see if ultracapacitors can provide a more cost-effective energy storage system for microgrids—and better response time—than batteries.

      Pure-play battery or hybrid grid energy storage? | Energy Storage News

      Transmission and distribution (T&D) organizations within electric utilities are transitioning to battery-based grid energy storage solutions. As a result, these groups are reporting that the applications for this “reservoir of electrons” reaches far beyond the grid applications that they are now busy solving. Even regional energy system operators such as independent system operators (ISOs), distribution system operators (DSOs) and transmission system operators (TSOs) are implementing these advanced battery energy storage systems as a means of providing stability and reliability within their respective energy system service territories.

      Duke's Front and Back of Meter Ultracapacitor-Battery Goes Live

      A large-scale system combining advanced batteries and ultracapacitor energy storage to provide both grid services in front of the meter and behind the meter solar shifting is up and running in North Carolina, according to one of the project’s partners. Maxwell Technologies’ director of business development, Dr Kimberley McGrath, told Energy-Storage.News that the ‘hybrid ultracapacitor-battery energy storage system’ which combines multiple applications simultaneously, is an “ideal pilot” and is now operating.

    5. Ireland's First Combined Ultracapacitor & Energy Storage Facility

      Ireland's First Combined Ultracapacitor & Energy Storage Facility

      Ireland intends to achieve 40% renewable energy by 2020. This is an ambitious goal, considering most of this electricity comes from large-scale wind farms. “The challenge is that it is an island grid, with only limited connection to the UK,” said Klaus Harder, Business Development Manager at FREQCON GmbH. Some winter nights, the Irish grid will have to take 75% of its electricity from renewable sources. This calls for additional services, so FREQCON deployed Ireland’s first ­combined ultracapacitor & energy storage facility for the Tallaght Smart Grid Testbed in South Dublin County.

      Graphene Aerogels Promise Enhanced Energy Storage Performance

      Lawrence Livermore researchers have turned to graphene aerogel to develop an enhanced electrical energy storage solution that eventually could be used to smooth out power fluctuations in the energy grid by boosting the performance of commercial supercapacitors. The team's graphene aerogel-based supercapacitor electrodes are suitable for the electric vehicle applications because they feature high surface area, good electrical conductivity, chemical inertness and long-term cycling stability.
