New MIT metal-mesh membrane could solve longstanding problems with liquid metal displacement batteries; inexpensive grid power storage

Green Car Congress

A battery, based on electrodes made of sodium and nickel chloride and using thea new type of metal mesh membrane, could be used for grid-scale installations to make intermittent power sources such as wind and solar capable of delivering reliable baseload electricity. A new metal mesh membrane developed by researchers at MIT could advance the use of the Na–NiCl 2 displacement battery, which has eluded widespread adoption owing to the fragility of the ?"-Al Al 2 O 3 membrane.

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) In a new concept for battery cathodes, nanometer-scale particles made of lithium and oxygen compounds (depicted in red and white) are embedded in a sponge-like lattice (yellow) of cobalt oxide, which keeps them stable.

UNSW, H2Store to develop hydrogen storage for renewables; residential and commercial P2G

Green Car Congress

Researchers at UNSW Sydney (Australia), with partner H2Store , an Australian start-up, have received a $3.5-million investment from Providence Asset Group to develop a hydrogen hydride storage system that could mean cheaper, safer storage for renewable energy for a range of applications, including residential. The team hopes to have a 5 kW home storage system prototype ready by the end of 2019 and a product on the market late in 2020. Hydrogen Hydrogen Storage Power-to-Gas

In effect, cars would be acting like tiny power stations. ’s power generation, he said. Sven Thesen, the communication and technology director for Better Place , a start-up that is gaining traction (see this recent New York Times article ) in its effort to create a network for electric cars in various countries, likened the concept of electric cars to cellphones. In the city of the future, could power suppliers be rivalled by innovative construction firms?
