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. Eronen says, laughing.

Aqua Metals is building a more sustainable battery recycling ecosystem

Charged EVs

The economic benefits of recycling Li-ion batteries are clear, but at present, only a small percentage of them are recycled. In contrast, lead-acid batteries have a 99% recycling rate in the US. The two main processes for recycling lithium-ion batteries are pyrometallurgy and hydrometallurgy.

Hydrogen Battery "Sponges" Store Solar for the Grid

Cars That Think

A novel project in Australia aims to harness the sun’s energy in two different ways: by storing it and by using it to produce green hydrogen. Dozens of solar farms in the country’s southeastern region are slated to use “ hydrogen batteries ” in coming years. Lavo’s hydrogen battery aims to capitalize on both energy trends, Yu said.

Groupe Renault launching project to build biggest energy stationary storage system from EV batteries in Europe

Green Car Congress

Groupe Renault is launching its “Advanced Battery Storage” program, which aims to build the biggest energy stationary storage system using EV batteries yet designed in Europe by 2020 (power: 70 MW / energy: 60MWh). The storage capacity will then be gradually expanded over time to contain the energy of 2,000 EV batteries.
