Parkway South High School To Power Some Of Its Energy From Underground Heat

[TexasProgresive]

1. Reading the article I think "power" is not quite the right word.

The article is a bit sketchy as to exactly what they are doing. I suspect the wells are being used as heat sources and sinks for heat pumps. This is not particularly new technology. There are a few home owners in my area that use two wells for this purpose, one water is drawn up to the unit and the other is an injection well. The water has the capacity to supply heat and to absorb heat much more efficiently than air. Air heat pumps are basically air conditioners that work in reverse in winter. They don't do well when the air temp drops to freezing and are supplemented by resistive heat strips. Since ground water has a consistent temperature this is not a problem.

If the temperature in the ground water is high enough then it could supply power.
