Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

Researchers at Harvard have demonstrated a metal-free organic–inorganic aqueous flow battery—a quinone–bromide flow battery (QBFB)—as an example of a class of energy storage materials that exploits the favorable chemical and electrochemical properties of a family of molecules known as quinones. —Huskinson et al.

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

The company is building these shipping container systems, which work like giant batteries that store energy as heat and pressurized air , rather than a chemical reaction (Cheesecake’s name is derived from a nerdy acronym for their technology.) Some companies have landed on thermal storage.

A Driver-Centric Approach Is Essential to Broad Vehicle-to-Grid (V2G) Adoption

Driivz

The 2020 International Energy Agency’s Global EV Outlook projects that by 2030, the share of electricity going towards EV charging could rise to as high as 4–10% at peak demand. V2G returns the energy stored in EV batteries to the grid. EV owners don’t view their cars as devices that store energy for someone else’s use.
