Dublin council chooses hybrid storage for smart grid testbed


The hybrid energy storage device combines an ultra-capacitor with traditional lead-acid battery technology

According to Energy Storage News, the lead-acid hybrid, called the UltraBattery, was developed by Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO), and has been commercialised by its former subsidiary Ecoult, now owned by US firm, the East Penn Manufacturing Company.

Ecoult said the Irish smart grid storage project will demonstrate energy storage can provide “synthetic inertia”, and outperform existing fossil fuel balancing resources, and show its UltraBattery system 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, has 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.”

IoT network in Ireland

In other recent news, French wireless network provider Sigfox and Dublin-based VT Networks have announced the availability of Sigfox low-power and cost-effective IoT connectivity in Ireland.

The announcement comes less than eight months after the two companies partnered to deploy the network in Ireland. According to a company release, Irish companies are quickly installing new IoT solutions to take advantage of the network.

Sigfox has already deployed its IoT network in France, Spain, Portugal, the Netherlands and Luxembourg, with Ireland as the sixth European country to complete full Sigfox network coverage.

Mark Bannon, CEO of VT Networks, said: “Irish businesses and farmers have been quick to understand the benefits that the Sigfox dedicated IoT network provides.

“We are excited to see this growing level of interest, and look forward to launching programmes that further integrate the network throughout the country.”
