What is the estimated cost of construction? It's my understanding that you need to go down 5 - 10 miles in geographically stable (non-volcanic) areas before you get enough heat for steam generation. That would seem to be costly and challenging, but I'm no engineer, so I'm sure they've thought it out.
Sounds interesting. In fact we need a proper independent expert estimation of the formulas and calculations made by the company specialists.
And of course practice is the best exam of the theory. So what are the parameters of the first experimental plant built in Canada? What is the output? How many kwt×hrs have been already produced?
Honestly, it sounds like they are trying to get a bunch of green investment to go on a party with.
30 years isn’t a long time. How long will it take to replenish the heat if the well is shut down?
Just couple it with solar thermal energy- problem solved
In the summertime, you pump heat into the system by collecting solar energy and pumping the warm water into the stone-thereby re-heating the stone-heat-battery. And in winter you pull it out again.
With this you have a system which is much longer reliable.
If you turn it off for a while, won't the heat completely replenish? How long would that take?
The answer to that question probably requires running a model. You might want to add specifics
All of the indications are that this would be a much cheaper way of generating base load than nuclear. So why isn't it happening? What is the hold up to a mass switch to base load geothermal?
idk the more i see about this the more its sounding fishier and fishier
No sheer will to sort out clean energy issue's from a governmental level to be honest. In theory, this could obliterate all energy industries. I've come to many conclusions, but i believe that there's no sheer will.
Until someone actually puts up a 100MW on grid using this technology, then only that's when governments and private sector capital will shift focus.
Is this partially in response to the paper discussing the reduction of the ambient heat present in the rock?
Do you add any kind of casing to the wellbore? I’m wondering if, without a pipe, you would ever hit a fissure in the rock interfering with the loop….
According to one of their other videos they are planning to install casing down to the target rock formation (I.e. the vertical bit of the well in the video).
For the laterals they are planning to apply a sealant to stop the fluids from escaping into the rock formation. I believe they call this "technology" rock-pipe or something
Interesting. So the well has a limited lifespan akin to a battery and producing at a higher rate will drain it faster.
Surely the rock wouldn’t go completely cold though? So wouldn’t even a “dead” well be useful at least for district heating after its electricity days are over.
I’ve never thought of geothermal as a non renewable/finite resource though
That is not exactly how it works, if you stop using the well it will warm up again, just the process might take years/decades... then you can use it again.
Is borehole stimulation used there?
No stimulation is used!
The fluid (e.g. water) remains within the wellbore at all times in the process - it is a self-contained system.
Stimulation would only be interesting if one wanted to promote fluid flow through the rock formation (e.g. towards a borehole). The system they are describing does not require any fluid flow through the formation itself - stimulation would not make their system any better.
It works on a close loop, means not all formations are suitable. How do we address losses of working fluids to the formation?
They are planning to apply a sealant to prevent working fluid loss. I believe they call this technology rock-pipe
Technically you could use it for all formations, but for instance for porous and permeable rocks there maybe more favourable and established technologies - I.e. traditional geothermal energy
What if at the end of 30 years you reverse the flow? Would that buy you some more time?

PERFECT!
Amen.
Why have the Eavor loops on top of each others like this.

Have it on alternate rows like this.

That way there is less of a vampire effect on each others.
