It depends what you want to use the geothermal heat for. In Norway, in the winter, a lot of the energy use is going to be heating. Geothermal heating systems are quite common in northern and don’t require lossy conversion
- ncmncm 4y agoAnd pure thermal uses are not good storage for high-grade energy forms, e.g. electric, because of conversion losses. In Norway, pumped hydro is a good place to park high-grade energy. That said, for rarely drawn-upon storage, conversion efficiency doesn't matter very much. It is why back when hydrogen electrolysis still lost 40% off the top, it was considered fine for long-term storage. Now that it has exceeded 90%, it is useful in more places.
