Lead-acid a good fit with flywheels in hybrid ESS

Mon, 11/28/2016 - 10:05 -- Xuan Zhong

Testing has proved that a lead-acid and flywheel hybrid energy storage system can handle renewable energy as a pilot comes to a close in Ireland.

The trial in County Offaly uses a 160kW lead-acid battery from Hitachi Chemical and a 60kW/30kWh flywheel by US company Beacon Power.

The hybrid system by energy consortium Schwungrad Energie, along with transmission system operator EirGrid (Irish Transmission System Operator), has shown the system can handle real-time response and power output requirements.
