Technology could boost renewable energy storage

Renewable energy sources like wind and solar are critical to sustaining our planet, but they come with a big challenge: they don't always generate power when it's needed. To make the most of them, we need efficient and affordable ways to store the energy they produce, so we have power even when the wind isn't blowing or the sun isn't shining. Columbia Engineering material scientists have been focused on developing new kinds of batteries to transform how we store renewable energy. In a new study published September 5 by Nature...
