Solar and Battery Companies Rattle Utility Powerhouses

Cars That Think

All eyes these days may be on Elon Musk's space venture—which has just put people in orbit —but here on Earth you can now get your monthly electric bill courtesy of a different Musk enterprise. The UK-based energy developer's just broken ground on a new four-acre battery storage site outside London, its third such site.

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.) Electric cars need lots of batteries, laptops need lots of batteries.

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.

Hybrid biomass flow battery stores electricity and produces valuable chemicals at the same time

Green Car Congress

Rechargeable batteries store electricity in their electrode materials, while redox flow batteries use chemicals stored in tanks attached to the electrodes. Researchers have now developed a battery system based on a hybrid cell, which not only stores and provides electricity but also produces valuable chemicals in a flow system.
