An interview with Marit Brommer, Executive Director of the International Geothermal Association.
What are some of the exciting new directions in geothermal energy?
There are many exciting new directions here are a few: electricity conversion in low temperature environments (i.e. temperatures up to 150° Celsius), the search for deeper and hotter reservoirs (between 4 and 8km depth for instance NW Europe) in non-volcanic rocks, smart cities initiatives with the vision to replace the baseload from a coal-based district heating systems to a geothermal based system, and small island development states in the fury of climate change wanting to become independent from fossil-fuels and adopting renewable technologies such as geothermal in their journey towards autonomy, independence and a clean and green future.
