The use of hydrogen as a means of storing energy is an idea that has been around for a long time. However, the technology to make it happen has not been available until recently.

Hydrogen can be produced using solar energy and water. This process is known as “water splitting”, and it produces hydrogen gas at one end and oxygen at the other. The hydrogen can then be stored for later use in fuel cells to generate electricity or heat.

This technology is also environmentally friendly because it doesn’t produce any carbon dioxide emissions when used in this way.
