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.

BNEF report finds hydrogen promising decarbonization pathway, but carbon prices and emissions policies required

Green Car Congress

The falling cost of making hydrogen from wind and solar power offers a promising route to cutting emissions in some of the most fossil-fuel-dependent sectors of the economy, such as steel, heavy-duty vehicles, shipping and cement, according to a new report from BloombergNEF (BNEF). Storing and moving hydrogen is challenging.

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

Green Car Congress

AQDSH 2 refers to the reduced form of AQDS. Quinones are naturally abundant, inexpensive, small organic molecules, and similar to molecules that store energy in plants and animals. Solid-electrode batteries maintain discharge at peak power for far too short a time to fully regulate wind or solar power output. Cell schematic.

U.N. Kills Any Plans to Use Mercury as a Rocket Propellant

Cars That Think

Bender is referring to the 2013 Minamata Convention on Mercury , a U.N. It’s also liquid at room temperature, making it efficient to store and use. And it’s cheap—there’s not a lot of competition with anyone looking to buy mercury. Three quarters of that mercury, the researchers suggested, would eventually wind up in the oceans.

Electrostatic Motors Reach the Macro Scale

And, perhaps even better, they would use only cheap, plentiful materials, rather than the rare-earth elements, special steel alloys, and copious quantities of copper found in conventional motors. As a dielectric, air has low permittivity, meaning that an electric field in air can not store much energy.

Tesla loses another director – Rohan Ma, energy/autobidder lead

Baua Electric

Software like this is what allows grid-tied batteries to buy and sell from the grid, and help the owners of those batteries to make money by arbitraging energy – storing it when it’s cheap and plentiful, and selling it when it’s expensive and demand is high.

Why Warren Buffett is investing in electric car company BYD - Apr. 13, 2009

Tony Karrer Delicious EVdriven

His people at MidAmerican have studied clean technologies like batteries and wind power for years because of the threat of climate change. They generate fewer greenhouse gas emissions than cars that burn gasoline, and they have lower fuel costs, even when oil is cheap. Electric cars will be one answer. All times are ET.
