The wiki page designates them as geothermal heating (backyard), and geothermal power, for utility scale electricity.
Geo heat exchange can help keep homes in temperate zones quite comfy during weather extremes. If it’s 0°c out, it’s probably 10-15°c the same number of meters under ground.
By summer, when it’s 30°c out, you have that same lovely 10-15° temp going on. Geo heating is more effective for this in temperate zones hot summers, cold winters.
[ Geothermal heating was the next project at the old place in ny. My dear old sold it for what they paid, after I put near 9kw of solar on top. Now the current owners are sitting on 3x the property value, so at least I’ve got that going for them… ]
It seems like the low hanging fruits of geo power are built around known hydro thermal ventings.
An update from Yilan. If this works, it could be (according to the Minister of Economic Affairs) the first of a thousand similar projects around Taiwan.
Taiwan has more volcanic rock than plutonic rock. Dacite makes up the strata of the Tatun and Keelung volcanoes, as well as the Coastal Mountain Range, whereas basalt forms the Penghu Archipelago.
These rock types are not favourable for hosting uranium deposits.
No information on uranium exploration has been reported and no uranium resources have been recorded. Given the geology of the island, the potential for any discovery is regarded as very low [3.8].
I get about 20 zircon grains (about maybe 100um in length) for a 1kg piece of granite… it’s not a whole lot. Each zircon crystal has maybe some ppm of uranium in it. It’s only significant for dating the rock, not getting nuclear materials.
Plutonic rock simply refers to igneous rocks such as granite, formed from magma that slowly cooled in the crust over a very long period of time (like millions of years).
The uranium is to determine how long ago this happened.
They started years ago. No? One of the guys I work with has parents renting land to the governemnt and have already drilled it and opened up a hotspring. Last I heard, they are having trouble hitting the right marks, but this is a few years already. And millions of public funds to make decorations for the hotspring
I thought, for some reason, Taiwan was already taking geothermal somewhat serious and doing a fair bit already…?
I have that sense as well. Seen a number ofnprojects around Taiwan doing this. I wonder if its a genuine effort or just drilling for public flaunting. Either way, the one I know better is open to the public and and Co see their cute baseball statues with their so far “not deep enough” drilling haha.
I’m just going to go with propaganda. If geothermal is actually seen as viable, they would have been exploited to hell and back. Coal power is used because it’s the cheapest, and least problematic energy source out there.
