ORNL demos 20 kW bi-directional wireless charging on UPS PHEV truck; 11" air gap, >92% efficiency

Green Car Congress

The system transferred electricity from the power grid to the vehicle battery terminals at more than 92% efficiency. ORNL’s bidirectional technology is fully compliant with grid power quality standards. The technology takes energy from the grid and converts it to direct current (DC) voltage.

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

Green Car Congress

In a paper in Nature , they suggest that the use of such redox-active organic molecules instead of redox-active metals represents a new and promising direction for realizing massive electrical energy storage at greatly reduced cost. For this reason, a growing number of engineers have focused their attention on flow-battery technology.

Continuous test operation begins for large-format Li-ion energy storage system at power plant

Green Car Congress

Evonik Industries, STEAG, and other project partners put a lithium electricity storage system (LESSY) into operation at STEAG’s Fenne power plant in Völklingen, Saarland, Germany. The storage system, which is housed in a shipping container, can thus help to stabilize the grid. Installed capacity is 466 MW.

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

The shipping containers, which house a Frankenstein-like assortment of machine parts—motors repurposed from Volvo truck engines, giant tanks of compressed air, huge silos of piping hot sand—are produced by a company called Cheesecake Energy. Getting a 100 percent decarbonized grid is nothing but an optimization problem.”—Matthew
