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. The battery warehouse consists of 14 used lithium-ion electric bus batteries.

IIASA-led study proposes Underground Gravity Energy Storage as long-term energy storage solution for renewables

Green Car Congress

However, because sunshine and wind are inherently variable and inconsistent, finding ways to store energy in an accessible and efficient way is crucial. While there are many effective solutions for daily energy storage, the most common being batteries, a cost-effective long-term solution is still lacking.

Georgia Tech researchers develop aluminum-foil-based anodes for all-solid-state Li-ion batteries

Green Car Congress

Woodruff School of Mechanical Engineering and the School of Materials Science and Engineering, is using an aluminum-foil-based anode in a solid-state Li-ion battery to create batteries with higher energy density and greater stability. The new battery system is detailed in an open-access paper in Nature Communications.

Heating Buildings With Solar Energy Stored in Sand

Cars That Think

In a region known for long, dark winter nights, Polar Night Energy is building a system in the city of Tampere that can heat buildings with stored solar energy — all day, all night, and all winter long. This means that storing and distributing energy is as important as its generation. The apparent contradictions do not end there.

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) V in O 2 (gas) → O x− (condensed phase), and η charging > 1.1

Renault and Powervault in EV battery “second-life” partnership trial

Green Car Congress

In the UK, Renault and Powervault are partnering to re-use electric vehicle (EV) batteries in home energy storage units. This partnership will reduce the cost of a Powervault smart battery unit by 30%, helping Powervault to bring home energy storage to the tipping point of mass-market roll-out in the UK.

Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

While rechargeable batteries are the solution of choice for consumer-level use, they are impractical for grid-scale consideration. Scientists have been looking for solutions in gravity energy storage , thermal or geothermal storage , and also molten-salt batteries. He expects the battery to retain over 80% of its charge in that period.
