Minimally Orchestrated Storage Technology for Duration Addition to Electricity Storage
Columbia University's Electrochemical Energy Center will develop a long-duration grid energy storage solution that leverages a new approach to the zinc bromine battery, a popular chemistry for flow batteries. Taking advantage of the way zinc and bromine behave in the cell, the battery will eliminate the need for a separator to keep the reactants apart when charged, as well as allow all the electrolyte to be stored in a single tank, instead of multiple cells. This reduction in “balance of plant” hardware will reduce system cost.
If successful, DAYS projects will provide new forms of long-duration stationary electricity storage systems that enhance grid resiliency, provide low-cost energy capacity, support grid infrastructure, and enable a greater share of intermittent renewable resources in the generation mix.
Long-duration storage can help prevent blackouts and smooth overall grid operation, improving resilience and enhancing grid security.
New, extended storage options could enable greater integration of intermittent renewable energy sources, greatly reducing emissions from the power sector.
Energy storage technologies could help improve grid efficiency and promote the growth of domestic renewable energy sources.
