The battery performance scorecard is DNV GL’s first annual report to help equip energy storage product buyers with objective data to guide their purchase strategies.

The scorecard provides an independent ranking and evaluation of battery vendors based on testing performed in DNV GL’s laboratories.

For instance, helping buyers meet the time pressures of project finance and to buy high performing batteries.

The scorecard is expected to help accelerate the energy storage market as it eliminates the unavailability of market data which is a key obstacle to market acceleration, according to a company statement.

Key findings of the energy storage scorecard include:

  • The Li-ion Nickel Cobalt Manganese chemistry is the most commonly used battery, addressing 88% of all tested batteries.
  • 33% of tested batteries showed decreased throughput beyond the group average when cycled near the middle of the SOC band, 44% at the top, and 22% at the bottom. Throughput quantifies the total energy discharged, which diminishes as a battery age.
  • 22% of participants showed better throughput at elevated temperature, and 22% showed their lowest throughput at elevated temperature. 33% showed their lowest throughput at low temperatures.

DNV GL predicts the electrification of energy and transportation segments, and an influx in renewables will positively impact on the energy storage market.

The market is crucial for the energy transition and is expected to record a growth of around 50TWh in installed capacity by 2050, according to the firm’s Energy Transition Outlook.

DNV GL predicts that by 2050, solar PV, onshore wind, hydropower and offshore wind will account for 80% of global electricity production.

“Having access to this data will reduce independent engineering review time from months to weeks, which is a major advantage that benefits all parties involved. When battery manufacturers participate with DNV GL in the Scorecard, we can connect buyers with suppliers while providing objective data for their project,” noted Rich Barnes, executive vice president at DNV GL - Energy North America.
