In this episode, we dive into the transformative potential of long-duration energy storage (LDES) for achieving zero-emissions grids by 2050. Using insights from a study on the Western Interconnect grid in North America, we explore how varying grid conditions—from solar and wind capacity to hydropower availability—impact the value and optimal deployment of LDES. Join us as we unpack key findings, including the ability of LDES to reduce electricity costs during peak demand, support renewable-heavy grids, and lessen the need for extensive transmission expansion.
