Innolith gears up for Second Generation Battery Technology with Proven Innovations from GridBank Trials.

Following the completion of technology trials, Innolith is to decommission its 2.2 MW, 1.1 MWh GridBank located in Hagerstown, Maryland.

The GridBank, which was installed in August 2017 to deliver frequency management services for the PJM grid, has recently provided a testbed for Innolith technology innovations.   This included the installation of new cell interconnect technology and battery management systems that enabled the GridBank to achieve its highest ever score with a PJM Performance Rating of over 96% for December 2019.

“The GridBank has proven that our lab experience, which saw our cells charged and discharged for over 50,000 cycles, has been successfully replicated in the PJM production environment,” explains Markus Borck, Chief Engineer of Innolith AG.  “The GridBank has also served as a highly effective test bed for battery innovations that we will be bringing to market soon in our next generation of technology.

During its operation the GridBank saw a total throughput of 8.4 GWh over 5,150 cycles.  This included a daily peak performance of 17 cycles with a 22MWh throughput.  During its fully operational phase, the GridBank recorded an average score of 95.7% in the PJM Performance Ratings, making it among the best in class for frequency regulation providers.

The GridBank also provided a testbed for a technology trial that saw new Innolith cell interconnect and battery management systems tested.  These trials, that were completed in November 2019, led to an average PJM Performance Rating in December 2019 of 96.3% with a record daily high of 97.2%.

The technology innovations proven through the production operation of the GridBank will be applied to Innolith’s forthcoming second generation of inorganic battery technology.

“The Hagerstown GridBank is based on a first generation of our technology but has enabled us to trial some absolutely key innovations,” explains Borck.  “These innovations will now flow into our second generation of inorganic battery technology where we will see a quantum leap in energy density while preserving the clear advantages in cycle durability and non-flammability.”
