Electrovaya launches Li-ion residential energy storage system; 3 kWh – 20 kWh

Green Car Congress

The battery stores power from the grid or from solar panels and stores it for later household use. For consumers subject to time-of-use charges, the EnergyBlock can be used to store off-peak power to be used later during peak times, lowering the amount of peak-rate costs for the user.

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

Green Car Congress

Unlike other devices, the team’s is the first to utilize oxygen anions (negatively-charged ions) instead of cations (positive ions) to store its energy. The device uses a perovskite material (LaMnO 3 ), a structure containing vacant sites where oxygen anions can be stored, making these advancements a possibility. Resources.

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

Green Car Congress

Discharge mode is shown; the arrows are reversed for electrolytic/charge mode. Quinones are naturally abundant, inexpensive, small organic molecules, and similar to molecules that store energy in plants and animals. Thus the amount of energy that can be stored is limited only by the size of the tanks. Cell schematic. Background.

Skylark Restaurants in Japan to offer free EV recharging at 900 locations

Green Car Congress

Skylark will be gradually supplementing these with fast chargers as well, so customers will be able to get a full charge while they eat. Theoretically you could tour the entire country paying nothing for your travel and eating cheap at Skylark’s restaurants.

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

Green Car Congress

The team, led by Yiying Wu, professor of chemistry and biochemistry, integrated a dye-sensitized photoelectrode into a lithium-oxygen battery along with the oxygen electrode to enable “photo-assisted charging” of the Li-air cell. The photovoltage generated on the photoelectrode compensates the battery’s charging voltage.

Solaris to present new generation hydrogen bus

Green Car Congress

The battery will be charged with power from the fuel cell. In addition, it will be possible to recharge it by means of a plug-in charging outlet (as is the case in standard electric buses). Hydrogen is stored in composite tanks on the roof; the mass of the tanks will be reduced by about 20% compared to previous models.

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

Green Car Congress

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. A promising way of storing solar energy is via chemical fuels, in particular hydrogen as it is considered as a future energy carrier. —Pawar and Tahir. Govinder S.
