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

Green Car Congress

In Viva housing cooperative, Riksbyggen, Volvo, Göteborg Energi and Johanneberg Science Park have created a unique system in which energy from solar panels on the roofs of the apartment buildings is stored in batteries that previously powered electric buses on route 55.

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. Out of Finland’s energy-related emissions, 82 percent come from heating domestic buildings (Ref.

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.

Fraunhofer suggests e-scooters as application for its magnesium hydride paste hydrogen storage technology

Green Car Congress

POWERPASTE stores hydrogen in a chemical form at room temperature and atmospheric pressure to be then released on demand, said Dr. Marcus Vogt, research associate at Fraunhofer IFAM. POWERPASTE is also cheap to transport, since no costly high-pressure tanks are involved nor the use of extremely cold liquid hydrogen.

Volvo Car Corporation developing flywheel kinetic energy recovery system; considering broad application

Green Car Congress

The flywheel’s stored energy is sufficient to power the car for short periods. The flywheel technology is relatively cheap. The energy in the flywheel can be used to accelerate the vehicle when it is time to move off once again, or to power the vehicle once it reaches cruising speed. Click to enlarge.

USC team develops novel organic redox flow battery for large-scale energy storage

Green Car Congress

Since grid-scale electrical energy storage requires hundreds of gigawatt-hours to be stored, the batteries for this application must be inexpensive, robust, safe and sustainable. Such a system would create a minimal impact on the environment, and would likely be cheap, they figured. —Yang et al.
