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.) Recent years have seen the construction of large lithium-ion battery farms that do just that.

KAUST uses laser pulses to boost performance of MXene electrode

Green Car Congress

Graphite contains flat layers of carbon atoms, and during battery charging, lithium atoms are stored between these layers in a process called intercalation. The researchers made an anode from the laser-scribed material and tested it in a lithium-ion battery over 1000 charge-discharge cycles. —Bayhan et al.

European Researchers Developing Multifunctional Structural Composite Material That Can Double as Energy Storage

Green Car Congress

Researchers from Imperial College London and their European partners, including Volvo Car Corporation, are developing a prototype multifunctional structural composite material composed of carbon fibers and a polymer resin which can store and discharge electrical energy and which is also strong and lightweight enough to be used for car parts.

Solar and Battery Companies Rattle Utility Powerhouses

Cars That Think

A decade ago it became possible to get your electricity in the UK from a department store chain (though with the actual power supplied first by a Scottish utility and— as of 2018 —arranged and managed by Octopus Energy). Without it, you are not going to get there." That would be something to reckon with.
