Energy storage is one of our most important tools for the energy transition. Without it, a renewably powered world doesn’t work—at least not on cloudy or wind-free days. Without it, beating the climate crisis feels far less attainable.
But right now, use of energy storage is often causing an increase in carbon emissions. California learned this the hard way through its Self Generation Incentive Program (SGIP). During 2016, non-residential SGIP Advanced Energy Storage projects increased GHG emissions by 726 metric tons of CO2. How? There was a timing mismatch: batteries were charging during times of dirty energy and discharging too often when solar or other renewable energy sources were plentiful. They needed the opposite to happen.
Now, after three years of toiling with various strategies, the state of California is about to implement the world’s first workable solution to the energy storage dilemma. California's breakthrough solution comes in the form of an emissions signal; it tells batteries when to charge and discharge based on highly granular grid emissions data. And it completely erases the carbon footprint of energy storage in California in an instant.
