Long duration energy storage technologies have an energy storage duration of more than 10 hours. In 2024, thermal energy storage systems could store power for 200 hours, while chemical energy storage technologies' storage duration ranged between 500 and 1,000 hours. These technologies had the longest storage duration, compared to a maximum storage duration of 25 hours for mechanical storage.
