PNNL: single-crystal nickel-rich cathode holds promise for next-generation Li-ion batteries

Green Car Congress

Researchers are working on ways to store more energy in the cathode materials by increasing nickel content. Nickel-rich cathode materials have real potential to store more energy. These carry advantages for storing and discharging energy faster. (Image courtesy of Jie Xiao | Pacific Northwest National Laboratory).

Pratt & Whitney Rocketdyne Receives $10.2M Contract for Concentrated Solar Power Tower with Thermal Storage Technology

Green Car Congress

Liquefied molten salt is circulated into the receiver, where it is heated to about 1,000 °F (about 538 °C), then stored in a large insulated tank. The energy from this stored molten salt is available on-demand to drive a steam turbine to create electricity.

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.) The compressed air, now cool and easier to store, is housed in a large air tank.

Gravity Batteries, Green Hydrogen, and a Thorium Reactor for China

Cars That Think

No battery is perfect, however, so engineers keep pushing for new and improved ways to store those electrons. The gravity batteries described in this story lift giant weights in the air or up mine shafts to store excess electricity, releasing the weights later on to recover the stored energy.

ARPA-E awarding $30M to 12 hybrid solar projects; conversion and storage

Green Car Congress

Under the FOCUS program, projects will develop advanced solar converters that turn sunlight into electricity for immediate use, while also producing heat that can be stored at low cost for later use as well as innovative storage systems that accept both heat and electricity from variable solar sources.

Honda develops process to reuse rare earth metals extracted from old NiMH batteries for new NiMH batteries for hybrid vehicles

Green Car Congress

Now, by applying molten salt electrolysis to this oxide, Honda has succeeded in extracting metallized rare earth that can be used directly as negative-electrode materials for nickel-metal hydride batteries. Earlier post.)

What is Home energy management system, why it is needed

Baua Electric

Energy Storage Systems Batteries or other storage systems can be integrated into a HEMS to store excess energy during periods of low demand and release it during peak demand times. These systems store excess energy generated during periods of high production and release it when demand is high or when renewable generation is low.
