Disruptive geothermal energy concept

The core of this project to exploit geothermal heat is absolutely fascinating in its simplicity. If you come from an oil and gas background I would encourage you to explore Eavor Technologies Inc.. It is a Canadian start-up looking to use the thermosiphon principle to bring natural heat to the surface which can be used for heating / cooling or electricity generation through a heat engine.
This innovation (patents pending) stems essentially from the advancements in the NA oil shale industry. Two 2.5km vertical wells, 2.5km apart, connected with precisely drilled multi-laterals, completed with proprietary pipe and filled with a proprietary working fluid form a gigantic radiator. Eavor's demonstration project in Alberta is up and running since Dec 4th 2019. The project in the Netherlands would be the first commercial (heat only) Eavor-loop and cost about EUR65mln. Assuming this configuration heats 16,000 dwellings than with a (NL) average of 10MWh per year per dwelling, this would be a 18MW installation, at ~$3000/kW. Not bad. Next question: what is the cost reduction potential from learning curves and scaling up the supply chain?
