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.

NREL: battery second use offsets EV expense, improves grid stability; recommendations

Green Car Congress

Although the supply of second-use batteries has the potential to overwhelm many high-value markets for energy storage by an order of magnitude or more, battery reuse by utilities would call for a large-scale supply capable of absorbing a significant portion of these components and diverting them from premature recycling or the waste stream.

This makes it possible for the waste heat from the electrical drive components to be made available to the interior of the Q7 e-tron quattro. For example, fuel economy statistics and a graphic display of the electric range is shown on the navigation map. The tanks can store around five kilograms (11.0 liters (1.0
