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) Nature Energy 1, Article number: 16111 doi: 10.1038/nenergy.2016.111.

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

Cars That Think

Electricity is a commodity that is bought and sold, and yet unlike most other commodities, it cannot easily be stored. Then, as electricity entrepreneurs expanded power generation and transmission capacity, they faced the new problem of what to do with all the cheap off-peak, nighttime electricity they could now produce.

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. The state of the art is to use a solar panel to capture the light, and then use a cheap battery to store the energy. Their hybrid design uses only three.

Exeter team develops low-cost photoelectrode for spontaneous water-splitting using sunlight

Green Car Congress

Researchers at the University of Exeter (UK) have developed a novel p-type LaFeO 3 photoelectrode using an inexpensive and scalable spray pyrolysis method. The researchers believe this new type of photoelectrode is not only cheap to produce, but can also be recreated on a larger scale for mass and worldwide use. —Pawar and Tahir.
