Heating Buildings With Solar Energy Stored in Sand

Cars That Think

When we turn up the heat in our homes and workplaces, we must balance our personal need for warmth with the global impact of burning fossil fuels like oil, gas, coal, and biomass. Out of Finland’s energy-related emissions, 82 percent come from heating domestic buildings (Ref. The apparent contradictions do not end there.

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

Green Car Congress

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. Quinones are abundant in crude oil as well as in green plants. You could theoretically put this on any node on the grid. —Michael J.

New MIT metal-mesh membrane could solve longstanding problems with liquid metal displacement batteries; inexpensive grid power storage

Green Car Congress

A battery, based on electrodes made of sodium and nickel chloride and using thea new type of metal mesh membrane, could be used for grid-scale installations to make intermittent power sources such as wind and solar capable of delivering reliable baseload electricity. The work was supported by the French oil company Total S.A.

Governor George Pataki Calls for 40% Penetration of Electric Drive Vehicles in US by End of Decade

Green Car Congress

We need an interactive grid to make this work. We have to change the regulatory requirements to recognize the investments in the smart grid that have to be made. Right now we are operating with a grid that was not adequate at middle of the last century. If you build it, they aren’t coming. Gasoline is too cheap.

It’s about one-twentieth the size of the minibus-scale geostationary satellites already in orbit, allowing for cheap and quick deployment. The wind part of the project plans a total of 3,000 megawatts from wind farms it will build in three counties in New Mexico. But this satellite is the first of a new breed, dubbed microGEO.

Opinion: Why Buffett Bet A Billion On Solar: Miles Per Acre Per Year

Green Car Congress

During the late innings of the ICE-age (as in the Internal Combustion Engine age) it has become clear that feeding gasoline and diesel to the next billion new cars is not going to be easy, or cheap. However, building more coal and gas power plants to make miles for transport is counter-productive if the game plan is to reduce carbon output.

Clearing the roadblocks to electrification of heavy-duty trucks

Charged EVs

When we were first starting off at Daimler Truck, trying to find a battery cell supplier that would build us a pack that was good in the truck was difficult. I was a big part of building the first-of-its-kind—at least in the Western world that we knew of—heavy-duty charging site in Portland, Oregon. Rustam Kocher: It is. It won’t work.
