Hydrogen Battery "Sponges" Store Solar for the Grid

Cars That Think

A novel project in Australia aims to harness the sun’s energy in two different ways: by storing it and by using it to produce green hydrogen. Operators can use the systems to store energy from solar panels and deliver power to the grid during cloudy days or at night. reduce pressure and add stability to the grid,” Yu said.
