Sunlight is one of the most abundant energy sources on Earth, but we can’t use it wherever and whenever we want. This is because storing solar energy and transporting it from sunny regions to places with limited sunlight is still costly and inefficient.
However, a team of researchers has now shown that sunlight can be stored inside a liquid using simple chemical materials and later converted into hydrogen gas in complete darkness. Plus, this method won’t require wires, batteries, or power grids to transport energy.
Moreover, until now, no system using simple, commercially available materials had managed to store solar energy and later release it as hydrogen without any external electricity. The new research suggests that this barrier has finally been crossed.
