Storage of clean energy!

[Christophe]

You can store thermal energy in quite a lot of body like hydrated and dehydrated salt and phase changes:
with commercial realization:

and even make an ecolo cllimatizer:

The lime stores 0,32KWh / kg of CaO (ie 320KWh / m3 but 900 ° C of concentrated solar energy is required.
Gypsum or plaster stores much less, but at lower T 163 ° C !!
sea ​​salt too.
Calcium chloride too.

The number of bodies storing energy as well is huge with all the possibilities and temperatures.

A list of real possibilities:

http://en.wikipedia.org/wiki/Phase_Change_Material
At human temperature less than 100 ° C is stored at max 70 at 100 KWh / m3

The earth (clay, rock, etc.) free under our feet at + 36 ° C above the ambient stores 10KWh / m3 (between 20 ° C and 56 ° C).

Paraffin at 60 ° C 60KWh / m3 approximately (dodecanoid).

Overall view of the capacity possibilities 0,1KWh / L = 100KWh / m3 depending on the temperature:

Beautiful summary message, thank you dede, on thermal storage! I copy glue in that of palm oil: https://www.econologie.com/forums/stocker-de ... t7421.html but dedeleco, it might be necessary to make a subject dedicated to thermal storage by phase change (liquid / solid, crystallization ...) because I do not think we have one ... except that already quite complete on palm oil ... but does not concern crystallization ...

[chatelot16]

thermal storage is only used to use heat even

the conversion of energy into a transportable and salable storable liquid or gaseous fuel is much better!

the methanation (word that you made me discover) could be an interesting thing

problem know the word does not say how it works

transforming an exedent of energy into hydrogen is easy ... the CO2 is available almost free at some place, easy to liquefy and store

remains to understand the methanation

[Remundo]

To use the energy stored in the batteries of electric vehicles ...

A "mini" Smart Grid experiment carried out in Japan.

. The Mitsubishi experiment includes 5 i-MiEV cars, with their charging stations, and 5 i-MiEV batteries, which are used as back-ups, in a building whose roof is entirely covered with photovoltaic cells. power of 20 kW.

Chargers (3 kW each) are bidirectional for charging or unloading cars, or the batteries that act as back-up, and it is the software that controls everything according to the demand of the network, or the wish of motorists to have a car loaded at the earliest, or only the next morning.

Used batteries who serve as backup?
I did not understand everything there ???

Then also motornature could make a translation effort

[elephant]

You may have to see the translation. But I think that a battery become unfit for automotive use (50 60% of its autonomy) can still provide services in the context of this experiment.

[Former Oceano]

On the i-Miev we buy the battery, not like the zoe where it is rented. When the battery is used, it can be used as a fixed station on it. However, you have to buy a new battery for the car.

[raymon]

Storage with steps is a solution that has a very good performance (80%) I think. The life of a dam must be long enough to imagine 50 100 years.
A 23 step 2m 90 high can store 160gwh and would cost 6 billion euros.

power battery storage1 MW, for the island of Gran Canaria. Capacity of 3 MW.h

ENR: Gran Canaria gets 1MW storage system (Li-ion)

31 August 2012 Enerzine

The world leader in the design and manufacture of industrial batteries announced yesterday its willingness to provide a system of energy storage lithium-ion (Li-ion) megawatt for one of the first projects large-scale electricity storage in Europe.
Beginning 2013, Saft's fully integrated storage system, capable of delivering a megawatt (MW) of electricity for three hours, will be commissioned on the Spanish island of Gran Canaria as part of the STORE project (Storage Technologies Of Reliable Energy). This innovative project led by Endesa aims to demonstrate that energy storage can maximize the integration of renewable energies - wind or photovoltaic - into electricity networks and optimize network infrastructures.

Endesa, a subsidiary of the Enel Group and Spain's leading electricity supplier, is piloting this 11 million, partly financed by the Center for the Development of Industrial Technologies (CDTI) of the Spanish Ministry of Economy and Competitiveness.



.........................
The system will provide 3 MWh of energy that will smooth the load peaks of a substation and offset the intermittent production of wind farms and photovoltaic facilities, while rendering network services such as control of the power station. frequency and voltage of the network.

By flanking the site of TRITEC, a new product has just been developed.

It's a fully integrated block, the TRI-CELL



The concept is technically interesting. A reserve, up to 15 kWh in LiFePO4.

Surpluses are injected on the network. We have electricity in case of failure ...

The technical brochure in French

It's still a little expensive, but depreciable on 10 years according to the scenario German in Munich [in English]

3MW x 3h = 9MWh

11Meuro / 9MWh = 1,2 euro / Wh


comparison with a current battery of the genus 80euro 12V 100Ah

12V x 100Ah = 1200Wh
80 euro / 1200Wh = 0,066 euro / Wh

therefore lead acid batteries are not expensive compared to the previous project

remains the price of the converter to make the 50Hz

11Meuro / 3MW = 3,6 euro / W

small converter 100euro for 500W so 0,2 euro / W

so their thing has 11Meuro is not a feat! we can do the same thing and I think even cheaper without inventing anything
