In a revolutionary leap that could transform solar power from a marginal, boutique alternative into a mainstream energy source, MIT researchers have overcome a major barrier to large-scale solar power: storing energy for use when the sun doesn’t shine.
Until now, solar power has been a daytime-only energy source, because storing extra solar energy for later use is prohibitively expensive and grossly inefficient. With today’s announcement, MIT researchers have hit upon a simple, inexpensive, highly efficient process for storing solar energy.
Great news! Solar energy when the sun doesn’t shine. This is clean energy and one that really packs a punch. Just think about how much warmth the sun provides to this planet even though the average distance between the earth and the sun is 92,900,000 miles (149476000 kilometers). That is an extremely powerful source of energy.
Sunlight has the greatest potential of any power source to solve the world’s energy problems, said Nocera. In one hour, enough sunlight strikes the Earth to provide the entire planet’s energy needs for one year.
The researchers at MIT are not quite there, yet, but they will be soon. This is a must read and will benefit us greatly. It is the photosynthesis of plants that got these scientists thinking about how to split water molecules using the sun’s energy and then storing the hydrogen and oxygen gases in a fuel cell to be used as a carbon free source of energy. Brilliant!
