Graphene-based electrode prototype, inspired by fern leaves, could be the answer to solar energy storage challenge. Inspired by an American fern, researchers have developed a groundbreaking prototype that could be the answer to the storage challenge still holding solar back as a total energy solution. The new type of electrode created by researchers from RMIT University in Melbourne, Australia, could boost the capacity of existing integrable storage technologies by 3000%.

But the graphene-based prototype also opens a new path to the development of flexible ...

New approach for storage of concentrated solar thermal energy has been found, to reduce cost and make it more practical for wider use. The advance is based on thermochemical storage, in which chemical transformation is used in repeated cycles to hold heat, use it to drive turbines, and then be re-heated to continue the cycle. Most commonly this might be done over a 24 hour period, with variable levels of solar-powered electricity available at any time of day, as dictated by demand.

Conceptually, all of the energy produced could be stored indefinitely and used later when the electricity is...
