Leclanché unveils modular, plug-and-play solution for utility scale storage


From pv magazine International

Swiss battery manufacturer Leclanche has launched a new modular, plug-and-play solution for large scale energy storage which is claimed to have a reduced carbon footprint and environmental impact.

The LeBlock solution consists of two kinds of five-foot, interchangeable battery blocks that the manufacturer describes as easy to transport via boat or truck and to be installed on a slab or pad with the support of a crane. Both solutions, the company went on to say, allow for shipping “as a standard 20-foot ISO container and serve as the heavy-duty enclosure for the installed system.”

The blocks are pre-assembled and the batteries are already embedded when the product is shipped, with wiring and connectors also being pre-installed.

One of the two systems is called BatteryBlock and is presented as a pre-installed, liquid-cooled battery that racks up to a storage capacity of 745 kWh and is equipped with a fire protection system. The second solution, dubbed CombiBlock, consists of a series of battery blocks containing a centralized liquid cooling unit.

“LeBlock is designed to assist utility and [help] energy project managers seeking a less complex, [and more] reliable and cost-effective solution to replace or increase the reliability of the grid while helping to reduce carbon footprint and the impact of power generation on the environment,” said the company’s CEO, Anil Srivastava.

The manufacturer said that both solutions feature a fire-resistant construction, an emergency stop function, a fire detection and suppression system, isolation monitoring, and a ‘deflagration panel’ for relief of any internal pressure. “The system complies with all common international standards for transport and battery integration, including UN38.3, UL9540A, IEC62933, NFPA 855, NFPA 68 and more,” it further explained.
