Minimally Orchestrated Storage Technology for Duration Addition to Electricity Storage
Technology Description:
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.
Potential Impact:
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.
Security:
Long-duration storage can help prevent blackouts and smooth overall grid operation, improving resilience and enhancing grid security.
Environment:
New, extended storage options could enable greater integration of intermittent renewable energy sources, greatly reducing emissions from the power sector.
Economy:
Energy storage technologies could help improve grid efficiency and promote the growth of domestic renewable energy sources.
