Researchers propose new aluminum–sulfur battery with molten-salt electrolyte; low-cost, rechargeable, fire-resistant, recyclable

Green Car Congress

The multi-step conversion pathway between aluminium and chalcogen allows rapid charging at up to 200C, and the battery endures hundreds of cycles at very high charging rates without aluminum dendrite formation. —Pang et al.

Electric or hydrogen cars – which makes more sense for NZ?

Drive Electric

Hydrogen fuel cell vehicles (FCVs) use Hydrogen to generate electricity, producing only water vapour as a byproduct. FCEVs utilise the stored Hydrogen and combine it with oxygen from the air to generate electricity. This electricity is then used to propel the vehicle’s electric motor and recharge its battery.

Honda opens Smart Home US in California; produces more energy than it consumes; direct DC-DC EV charging

Green Car Congress

The home is also three times more water-efficient than a typical US home. A 10 kWh battery energy storage system in the garage, using the same lithium-ion cells that are used in the Honda Fit EV, allows stored solar energy to be used at night, when household demand typically peaks and electric vehicles are usually charged.

CO2-neutral hydrogen storage with a bicarbonate/formate system

Green Car Congress

Metal hydride tanks store hydrogen in a relatively manageable volume but are very heavy and expensive, as well as operating only at high temperatures or far too slowly. The nontoxic aqueous solution of formate is easily stored and transported. to sodium formate in 96% yield at 70 °C in water/THF without additional CO 2.
