Dovolj za oskrbo okoli 90 gospodinjstev letno, ni slabo za pilotni projekt. Me prav zanima koliko takih zapuščenih vrtin je v Sloveniji. Super, da jih takole ponovno uporabijo.
“The fact is, of all the literature I’ve read, if there is any particular area that needs to be rapidly developed, it is enhanced geothermal systems. As the core of base load earthly means of energy production. The potential is simply too enormous as a base load energy source. Today the world uses about half a zettajoule a year. 0.55 to be exact. Based on statistics from a few years ago. An MIT study found that, 13,000 zettajoule of power are currently reserved, hence only 0.0004% needs to be captured to power the world for an entire year. As far as what is practically accessible, with some technological improvements, according to MIT, 2,000 zettajoule are available. And again, we only use 0.55.
So, abundance potential is an understatement. No intermittency problems and the idea of depletion of such a vast source of heat is not an issue. Geothermal also uses much less land. A typical geothermal facility is about 404 square meters of land per gigawatt hour. While a coal facility uses 3,632 square meters per gigawatt hour. If we do a basic comparison of geothermal with coal using this ratio of square meters to gigawatt hour, we find that we could fit about nine geothermal plants in the space of one coal plant. Furthermore, if you take the thousand megawatt power station example to which there are a few with geothermal, operating at full capacity, 24 hours a day, seven days a week, it would produce 8.7 million megawatt hours a year. The world’s current annual usage in megawatt hours is about 153 billion, which means it would take an abstraction about 17,500 geothermal plants to match total global use.”
