Attending a roundtable forum on energy storage, Kevin Moran, Executive VP at Battery Council International, says he realized the discussions on large-scale battery storage will be a necessity for areas in the U.S. that are embracing and expanding their use of renewable energy sources. “The potential for an expansion in grid-scale battery storage installations may be even greater that I had previously thought,” said Moran in an article in Batteries International Magazine. “Several states have either passed, or are considering setting targets for [energy] storage.”
Moran pointed out that California recently passed a mandate that 100 percent of its electricity must come from renewable sources by 2045. “It’s hard to believe they can meet this goal without a massive investment in battery storage,” said Moran.
His views on energy storage for the future points to progress made on the battery storage front over the next several years, and that different battery chemistries will be competing with ways on how their products will meet the demands for energy storage in the future.
Large scale battery storage has been used in a variety of industrial applications utilizing specialized batteries designed for this purpose. Dutt Electronics, in Spain for example, utilized U.S. Battery RE series batteries in an autonomous system to balance the power output between stored energy consumption and battery charging during peak energy hours. While systems like these have proven to work in an industrial scale, they can also provide a solution to the growing need for energy storage and distribution in a larger scale.
Additionally, energy storage grids utilizing deep-cycle flooded lead-acid batteries for storage also offer an environmental advantage, according to the BCI, as these types of batteries are nearly 100-percent recyclable in a closed-loop system that offers zero impact on landfills.
