The researchers at Harvard University have developed a new type of flow battery, which is non-toxic, non-corrosive and can last for up to twenty years without any major maintenance requirements. These batteries are specifically designed to store solar and wind power for extensive periods, a development that is expected to bring remarkable improvements in the field of renewable energy production.

Lead researcher Michael Aziz, a professor of materials and energy technologies, says the new battery contains a membrane through which electrolytic ions pass on to the other side, notes Seeker. Highlighting the advantages of such a mechanism, Aziz says the flow batteries can be made bigger by using bigger electrolytic solution tanks, and also they can be quickly recharged by replacing the electrolyte.

An area that these batteries leave unaddressed is the relatively high cost of energy stored. The Department of Energy aims to slash this expense to less than $100 per kilowatt-hour in order to present the renewable energy as a competitive alternative to power produced in traditional power plants, writes Digital Trends.
