Technology Strategy Assessment
Grid energy storage is a relatively new opportunity for PbA batteries; it is driven largely by the rise of solar and wind renewable energy and the need to address their intermittency issues. As grid renewable content increases to a level that is characteristic of deep decarbonization durations, greater than 10 hours will be required LDES).
Carbon-Enhanced Lead-Acid Batteries
Lead-acid batteries are currently used in a variety of applications, ranging from automotive starting batteries to storage for renewable energy sources. Lead-acid batteries form deposits on the negative electrodes that hinder their performance, which is a major hurdle to the wider use of lead-acid batteries for grid-scale energy storage.
