South Dublin County Council has installed a new hybrid energy storage solution for the Tallaght Smart Grid Testbed which promises to outperform fossil fuel resources.
The new technology, which is made by Australian firm Ecoult and is called UltraBattery, is being used for the first time in Europe in a trial to provide back-up services for electricity grid.
Ecoult said the Tallaght smart grid storage project will demonstrate energy storage can provide “synthetic inertia”and can deliver system services in accordance with Ireland’s new DS3 grid programme, to deliver a “secure sustainable electricity system”.
Freqcon, a German energy systems developer was appointed by South Dublin County Council and the Irish Micro Electricity Generation Association (MEGA), to deploy energy storage systems for the Tallaght project, and have recruited Ecoult to install the UltraBattery system.
Ecoult chief executive John Wood, said:
“The UltraBattery is a hybrid technology.
“It contains both battery chemistry and ultracapacitor technology built into each cell. This Australian invention has the safety, sustainability and dependability of lead-acid, and has been shown to outperform other battery chemistries in similar applications
“Since the technology is built on a proven and safe lead-acid platform, UltraBattery cells are recyclable and we’re delighted that Freqcon has chosen to partner with our technology and storage system.”
Freqcon chief executive Norbert Hennchen added:
“The market for grid-tied energy storage systems is growing, and fast frequency response is a valuable system service to the grid.
“Ecoult’s hybrid lead-acid UltraBattery is a very promising technology in this space and we are excited to partner with Ecoult and deploy the first unit in Europe.”
Traditional lead-acid batteries are used all over the world, with most types suited to either high-power or sustained energy discharge.
Manufacturers say UltraBattery performs both of these tasks better than traditional batteries, and combines these capabilities with a specialised capability for operation in partial state of charge.
