Project name:

Power generation using low temperature geothermal fluids

Status: Idea
Creation date: 19-11-2021

Project objectives:

REPSOL SA is looking for innovators/experts who could provide them onboard thought leading solutions specifically in Bioeconomy sector. In particular:

Challenge Description
Transformation of geothermal resources into electricity suffers from the fact that the efficiency of the process is low. For a geothermal fluid below 90 ºC, the traditional ORC (Organic Rankine Cycle) has a net efficiency lower than 4%. This low efficiency limits the commercial use of these low temperature geothermal resources for power generation. Thus, the aim is to develop new technologies: new generation equipment’s (heat exchangers, turbines, etc.), improved thermodynamic cycles, new thermal fluids or combination of them, able to increase the net efficiency of the transformation from geothermal heat to electricity.

Technical requirements
The technologies offer must comply with:
- Be able to generate electricity from a geothermal fluid at temperatures in the range of 60-90 ºC
- Process efficiency must be at least 5-10% (net, from thermal watts to electric watts)
