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

Professor Kondo-Francois Aguey-Zinsou and his team at UNSW’s School of Chemical Engineering have developed a system that provides cheap storage and transportation of hydrogen which they expect will provide a new alternative for energy storage within two years. materials such as magnesium hydride (MgH 2 ) and lithium borohydride (LiBH 4 ) capable of storing hydrogen. We can actually store about seven times more energy than the current systems.

UT and ORNL researchers develop new class of pseudocapacitor; anion-based intercalation pseudocapacitance

Green Car Congress

Scientists in the The University of Texas at Austin’s College of Natural Sciences and the Cockrell School of Engineering, in collaboration with a researcher at the Department of Energy’s Oak Ridge National Laboratory, have developed the first of a new class of pseudocapacitor that may eventually lead to devices that can store electricity more densely and charge/discharge more quickly than other types of pseudocapacitors built to date.

Solaris to present new generation hydrogen bus

Green Car Congress

The new generation Solaris Urbino 12 hydrogen represents the continuation and development of a concept unveiled in 2014, when two articulated electric buses (Solaris Urbino 18.75) powered with hydrogen fuel cells as range extenders, were delivered to Hamburg. Hydrogen is stored in composite tanks on the roof; the mass of the tanks will be reduced by about 20% compared to previous models.

STFC Rutherford Appleton Lab spin-off seeking to develop and commercialize a novel solid-state hydrogen storage technology; transportation applications

Green Car Congress

The material could allow hydrogen to be stored in a cheap and practical way for transport applications, the company says. Although complex chemical hydrides exist that store hydrogen in concentrations that are well above 10 wt%, these materials have slow desorption kinetics and can release other chemicals such as ammonia or borazine which could poison a fuel cell.

Green Cars Part 4- Compressed Air

DIY Electric Car

Conventional cars work by exploding fuel and air in a chamber to exert force on the pistons, but what if rather than using an explosion to provide that pressure on the piston, you just stored your ‘fuel’ at a constant high pressure. That’s the concept behind the air car , and it looks like a pretty promising technology. Like hydrogen the air is not actually the source of energy, it is the storage medium, but unlike hydrogen the production of an air powered car is surprisingly cheap.

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

Green Car Congress

The basic concept of the integrated solar battery is to use the contribution of the photovoltage to reduce greatly the charging overpotential caused by the difficulty in efficiently electrochemically decomposing lithium peroxide (Li 2 O 2 ), the discharge product formed on the oxygen electrode. 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.

Millions will plug-in their electric vehicles [EV], plug-in hybrids [PHEV] and fuel cell vehicles [FCV] at night when electricity is cheap, then plug-in during the day when energy is expensive and sell those extra electrons at a profit. Several early models of passenger vehicles have enough energy stored in advanced batteries to power several homes for hours. Consumers expect a simpler concept.
