For battery energy storage systems, this means increasing the battery's energy capacity. This could be repowering a system following degradation or a commercial decision to increase the project's duration. Doubling a battery's energy capacity via duration could boost revenues by 37% today but up to 88% over its lifetime.
Adding more battery modules: increasing energy capacity by adding more cells by installing additional battery packs. Upgrading battery packs: replacing whole battery packs with better performing or cheaper technology, either lithium-ion or new chemistries such as sodium-ion.
Battery energy storage systems can lose up to 5% of their available energy capacity through degradation within the first year of operation and 40% after 15 years. Degradation is mainly linked to cycling. The transition to higher energy services means batteries are cycling more, causing them to degrade more quickly.
A comparison between each form of energy storage systems based on capacity, lifetime, capital cost, strength, weakness, and use in renewable energy systems is presented in a tabular form.
