Storage of electrical energy, possible today?




by sam17 » 11/04/12, 10:18

I just watched a TED conference on the subject.

This guy (Donald Sadoway) from MIT claims to have developed with his students a battery that would revolutionize the world of energy with as many repercussions as the day when an industrial solution was invented to extract aluminum from the ground.

It is a battery operating at high temperature from elements present in abundance on earth and inexpensive as a bonus.

I did not find any trace of it on the forum, then I post this over here. :)

Interesting to read:

At 700 ° C liquid Mg NaClKCl Sb with current density of 0,1A / cm2 max and risk of combustion and fire of liquid Mg if air leaks into it.

To see in the long term, because very recent and not tested, even in the number of 1000 cycles. 700 ° C is hot and therefore good thermal insulation necessary.

They managed to raise millions of dollars of funds from Total and Bill Gates to try to industrialize this discovery. It is indeed very very recent.

I do not know what this project will give, but the examples given in the conference are really exciting!

I have just read a CEA document on the processes used and under study concerning the storage of energy to respond to the peak consumption of electricity.

This is a quick list of
available technologies

the fashionable ones we should know,

here despise quickly and completely www.dlsc.ca by not citing it in what has been working since 2007, in thermal storage underground completely free, which is typical of CEA, responsible for promoting nuclear power by torpedoing the rest, pretending to study it, to make it apparently unprofitable !!!

However, our earth has been storing its original heat with that due to radioactivity for 4,5 billion years, and it is the simplest solution for storing solar heat !!!

More CEA ignores and does not try to reproduce on the cheap, which is what www.dlsc.ca by storing the summer heat for the winter, for 5 years already, a perpetual solution to eliminate all heating with nuclear electricity, without heat pump, without CO2, without catastrophic radioactivity pollution, and therefore CEA despises this solution eliminating nuclear power plants in perpetuity !!
Because CEA = Center for Nuclear Studies, does not deny its origins, nuclear power plants and the nuclear military !!

New:
A group of German researchers have been working since July 2012 on the MeMO project which aims to store surplus renewable electric energy to be able to release this energy when consumption reaches peaks.

The new materials have an energy density 5 times greater than Lithium-Ion for a relatively low cost. They are also not very explosive and not very toxic. The battery uses external oxygen during its charging phase and releases this oxygen in discharge. All made possible by a solid electrolyte in contact with a fine metallic powder.

If redox would be a new source of energy, the project will allow researchers to test various combinations of metals and alloys, especially in very high temperature situations.
