Smart Grid Today PODCAST: How Ultracapacitors Work in Grid-Scale Energy Storage Systems
September 17, 2018 | Maxwell Technologies
Two of the most pressing challenges grid operators face today include the increase of renewable energy on the grid and the decommissioning of traditional fossil and nuclear generation, which causes a deficit of inertia on the grid. Inertia, or stored rotating energy, is a key element that helps support the grid frequency.
In this podcast by Smart Grid Today, Dr. Kimberly McGrath, senior director of business development for Maxwell Technologies, discusses the specific advantages of ultracapacitor (supercapacitor) grid energy storage. Play the podcast below to hear more on these topics:
- Ultracapacitors’ unique ability to support high power, fast-responding applications
- The difference between ultracapacitors’ electrostatic energy storage process versus batteries’ electrochemical process
- The application of ultracapacitors for fast frequency response, renewables intermittency smoothing, generator and microgrid support, distribution scale storage for voltage and frequency stabilization, and grid resiliency
- How one standard cabinet of ultracapacitors can deliver approximately 1 megawatt of power
- Maxwell’s grid energy storage systems for large-scale grid energy storage deployments
- Key advantages for ultracapacitor grid energy storage, including cycle life,* wide operating temperature range, removing peak power demands from batteries, minimal cooling requirements, contribution to reduced battery maintenance and replacement, and infrastructure upgrade deferral
