Can hot dry rock projects generate electricity?

Most of the hot dry rock projects are relatively small in scale (<5 MW) in terms of power generation compared to the hydrothermal projects. The obtained flow rate after EGS is generally less than 40 L/s which is not high enough for commercial electricity generation.

Does organic Rankine cycle affect hot dry rock power generation system performance?

In this paper, a hot dry rock power generation system model based on conventional organic Rankine cycle was established. The performance of the system was evaluated by thermodynamic analysis, as well as energy and exergy analyses. Four types of organic working fluids were selected to investigate their effects on system energy efficiency.

Is hot dry rock a geothermal resource?

Hot dry rock (HDR), buried several kilometers deep inside the Earth with a temperature higher than 180°C, is a new type of geothermal resource and has drawn increasing attention [7, 8]. China has abundant reserves of HDR resources.
