    Energy Storage System Requirements: The Evolution of NFPA 855 and UL 9540

    The grid’s increasing dependence on intermittent solar and wind resources is a main factor in the expansion of energy storage systems, particularly large-scale installations. Lithium-ion batteries became the dominant solution due to rapidly declining costs and high energy density. However, unlike aqueous electrolyte batteries, lithium-ion chemistries are inherently susceptible to thermal runaway, an uncontrollable self-heating state that produces extreme temperatures…
