... and yes, reflection made. Since it is possible to safely store Co2 in the depths ... why not store heat in these "Confinement pockets" in addition to groundwater.
The cost of drilling is really not a problem ... the oil companies are drilling well to pump up their dirty oil! Both use these budgets to store at much smaller depths (between 30 and 300 m according to the ETHF), directly from the heat during the beautiful season. The whole thing has been stored by buildings that have become real heat traps!
The very serious Federal Polytechnic School of Zurich studied it ...>
... then we would not even have to look to isolate all the existing housing stock, which is a real colander, let's face it.
The goal is to use the colander effect to capture the heat heat diffused by the sun!
... at a stroke of a single, most of the current housing stock would not be so obsolete as that!
Afterwards, we can still tax EPFZ researchers with eco-tartuffes it's not them who still have something to prove on a technical level ... If they say it works, we can believe them!
Dedelco, I did not believe in this idea of storing heat in the ground, until the day I saw this animation of the EPFZ ...

Of course we have a lot to learn from you Alain Gand we are grateful to you, so much so that the term "Canadian well" is also used ^^
But in this case, the limit is set by the maximum allowed consumption (ie 10w / m2).
For the rest we also have our "graiiind north" with La Brévine ...> or the temperature goes down to -40 ° C ... what serves us as "laboratory" ^^
And of course the high mountains ...
But in the lowlands we rarely go below -10 ° C, which is why it is not obligatory (even if they are possibly wrong, it is the conso-max that prevails ^^)
... so it will surely come with the storage of heat in the ground;) we are working on it!Alain G wrote:ObamotOk, same as for Minérgie-P

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:

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:
