DeBary Green Hydrogen

As the DeBary Solar Power Plant captures energy from the sun, 74.5 MW of clean energy will make its way onto the grid. A portion of this energy will power the two 1-MW hydrogen electrolyzer units, which efficiently splits the water molecules into hydrogen and oxygen. Oxygen is then released into the atmosphere and the hydrogen is stored safely ...

Hydrogen explained

Hydrogen is the simplest element. Each atom of hydrogen has only one proton. Hydrogen is also the most abundant element in the universe. The sun, and other stars, are essentially giant balls of hydrogen and helium gases. Hydrogen occurs naturally on earth in compound form with other elements in liquids, gases, or solids.
