Volvo Buses in project researching use of second-life electric bus batteries to store solar energy

Green Car Congress

Volvo Buses is participating in a research project in which used electric bus batteries are used as solar energy storage units. Batteries from electric bus route 55 in Gothenburg, Sweden are being used for solar energy storage in a second-life application. Tenants are just starting to move into their new apartments.

KU Leuven team creates solar panel that produces hydrogen from moisture in air

Green Car Congress

Bioscience engineers at KU Leuven have created a solar panel that produces hydrogen gas from moisture in the air. Twenty of these solar panels could provide electricity and heat for one family for an entire winter. A traditional solar panel converts between 18 to 20% of the solar energy into electricity.

Researchers from MIT and Sun Catalytix develop an artificial leaf for solar water splitting to produce hydrogen and oxygen

Green Car Congress

The traces are for solar cells of 7.7% Researchers led by MIT professor Daniel Nocera have produced an “artificial leaf”—a solar water-splitting cell producing hydrogen and oxygen that operates in near-neutral pH conditions, both with and without connecting wires. solar-to-fuels systems. illumination.

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.

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.

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

Green Car Congress

Quinones are naturally abundant, inexpensive, small organic molecules, and similar to molecules that store energy in plants and animals. The technology could fundamentally transform the way electricity is stored on the grid, making power from renewable energy sources such as wind and sun far more economical and reliable. Background.

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. —Yu et al.
