DNV, the independent energy expert and assurance provider, today released the fourth edition of its Battery Scorecard report. This edition of the Battery Scorecard incorporates independent testing results from 19 different battery cell types, as well as an outlook on future battery technologies and a new interactive online dashboard. Energy storage is an important component of decreasing carbon emissions from power generation and transportation. Electrification of global energy systems combined with the distributed build out of storage supply chains will further accelerate market uptake of battery storage. DNV’s Battery Scorecard illuminates the most pressing questions around batteries, including safety, useful life, and degradation.
For products using batteries such as electric vehicles (EVs) and projects using batteries on the power grid, engineers, developers, and owners need a solid understanding of their battery system to achieve performance and financial goals. In addition, safety of individual cells and integrated battery energy storage systems (BESS) has taken on heightened importance especially in light of the few, but highly publicized battery fires. Selecting suitable technology suppliers is one of the most important and challenging endeavors for project developers. While batteries have been commercially available for decades, most stationary storage products are less than five years old. The Battery Scorecard provides project developers and owners data and insights that can help them select the correct technologies for the unique conditions of their projects.
“As energy storage further penetrates energy markets and infrastructure, proven safety and overall performance will become essential to projects. The best and most accurate way to ensure performance and safety is through testing,” said Richard S. Barnes, region president, Energy Systems North America at DNV. “Battery systems aren’t worth installing if they can’t be run safely and reliably.” For this edition of the scorecard, DNV tested 19 battery cell types through the Battery Scorecard Testing program across the following categories:
When evaluating and selecting suitable technology suppliers, DNV recommends that project developers take the following steps to ensure project success:
