Heating Buildings With Solar Energy Stored in Sand

Cars That Think

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. The apparent contradictions do not end there.

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) The researchers refer to these particles as nanolithia.

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

Green Car Congress

AQDSH 2 refers to the reduced form of AQDS. Quinones are naturally abundant, inexpensive, small organic molecules, and similar to molecules that store energy in plants and animals. Solid-electrode batteries maintain discharge at peak power for far too short a time to fully regulate wind or solar power output. Huskinson et al.

BNEF report finds hydrogen promising decarbonization pathway, but carbon prices and emissions policies required

Green Car Congress

In the years ahead, it will be possible to produce it at low cost using wind and solar power, to store it underground for months, and then to pipe it on-demand to power everything from ships to steel mills. Note: Clean hydrogen refers to both renewable and low-carbon hydrogen (from fossil-fuels with CCS). MMBtu) in 2050.

Razor E100 review: A great electric scooter for kids

Green Authority

However, you won’t be able to ride for more than an hour, as the 24V battery lasts for 40 minutes of continuous riding. The Razor E100 isn’t foldable, but it does have a small kickstand to prop upright and weighs ~25 lbs, which isn’t too heavy for children to push or carry should they run out of battery. Weight: 11.5
