Heating Buildings With Solar Energy Stored in Sand

Cars That Think

This sponsored article is brought to you by COMSOL. In a region known for long, dark winter nights, Polar Night Energy is building a system in the city of Tampere that can heat buildings with stored solar energy — all day, all night, and all winter long. This means that storing and distributing energy is as important as its generation.

New nanolithia cathodes may address technical drawbacks of Li-air batteries; scalable, cheap and safer Li-air battery system

Green Car Congress

An international team from MIT, Argonne National Laboratory and Peking University has demonstrated a lab-scale proof-of-concept of a new type of cathode for Li-air batteries that could overcome the current drawbacks to the technology, including a high potential gap (>1.2 V) V in O 2 (gas) → O x− (condensed phase), and η charging > 1.1

OSU hybrid “solar battery” uses photo-assisted charging to improve performance of Li-air batteries; “negative overpotential”

Green Car Congress

Researchers at The Ohio State University have developed a novel strategy to improve the efficiency and performance of non-aqueous lithium-oxygen (Li-air) batteries. O 2 batteries are based on the oxidation of lithium at the (lithium) metal electrode and reduction of oxygen at the air electrode to induce current flow. Earlier post.).

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

Around the same time, however, General Motors and other automakers were in the process of decommissioning their battery EV fleets, the key component of V2G. Electricity is a commodity that is bought and sold, and yet unlike most other commodities, it cannot easily be stored.

Alternatives to permanent magnet motors in EV traction applications

Charged EVs

In my very first article for Charged over 10 years ago, I opined that the Switched Reluctance Motor , or SRM, would eventually come to dominate the EV traction market, if for no other reason than the fact that it is almost as cheap as dirt to manufacture.
