With a new combination of existing technologies, we believe it is possible to create a renewable energy source –ultra deep EGS (Enhanced Geothermal Systems)– which is cheaper than coal.
The principle is simple: a higher temperature results in a better electricity conversion efficiency. So there is a double effect: a better conversion efficiency and the amount of available energy is higher. This double effect is stronger than the related cost of ultra deep drilling. Simple calculations demonstrate that ‘deeper is cheaper’.
