This solution describes a supercapacitor which is used in combination with flywheel and battery storage. Combined, the three technologies provide frequency balancing, including both synthetic inertia, frequency control and congestion management. The contribution of supercapacitors is frequency balancing. There is little information available on the details of the demonstrators, which are currently being set up.
Components & enablers
- Supercapacitor technology
State of the art in application and research
Supercapacitors can provide high power very fast but for a limited time. They are, therefore, useful in providing frequency balancing. OSMOSE develops two demonstrators where supercapacitors are included (WP3 and WP4).
The supercapacitors are part of a hybrid storage solution. The demonstrators cover the optimisation of supercapacitors, flywheel and battery storage in combination to provide frequency balancing (incl. synthetic inertia) and congestion management services.
Technology Readiness Level
Supercapacitor Technology: TRL 9 – Implementation
Supercapacitors are available and in use for commercial and grid application.
Hybrid Storage: TRL 6 – Demonstration
OSMOSE develops two demonstrators where supercapacitors are included (WP3 and WP4). The supercapacitors are part of a hybrid storage solution. The demonstrators cover the optimisation of supercapacitors, flywheel and battery storage in combination to provide frequency balancing (incl. synthetic inertia) and congestion management services.
