CHPM2030 Delphi survey - open round
The 2nd round of the CHPM2030 Delphi survey has finished. LPRC is currently processing the results. However if you would like to participate in the “open” round, for curiously of the statements, please go ahead and read what the Experts has to say about the future of Combined Heat Power and Metal extraction technology and more: share your own opinion!

The CHPM2030 project consortium ( is working on a novel, potentially disruptive technology that combines geothermal energy and mineral extraction in a single interlinked process: Combined Heat, Power and Metal extraction, or in short CHPM. This technology aims to increase financial feasibility of geothermal projects, by recovering valuable metals (e.g. Au, Ag, Sn, Fe, Li, REE, etc.) from the geothermal brine. Therefore the geothermal reservoir is chosen as such, that it coincides with a deep metal enrichment, allowing for both geothermal and mineral potential.
This survey is created by the working unit on Roadmapping and Preparation for Pilots. The goal in this work package is to set the ground for subsequent pilot implementation, including short-term planning (2030, preparation for pilots) and long-term planning (2050, horizon scanning, Delphi survey), and research roadmaps for 2030 and 2050 that elaborate on how to get to the desired vision by the selected timelines. This is a 2-round Delphi survey* that maps future development of uncertain but important areas for CHPM technology application.

"Within this form, statements are presented about the future, in 2050, and you are invited to review previous Expert comments and freely express your opinion."
During the 1st and 2nd rounds of this Delphi survey (May, 2018), more than 100 Experts participated worldwide. For each statement there is a short summary, highlights of previous comments and participation statistics of the inputs from the 1st round. The 1st round statements were mostly open ended, encouraging free commenting. In this round however, the statements themselves are mostly the same, but there are additional commenting sections regarding time horizon, emerging issues, technological challenges and key enablers. The survey aims to identify emerging issues of different aspects of the CHPM technology, many of which have been identified in the 1st round. To learn more about these identified emerging issues, and reflect on them, please go ahead and click next.

Your time horizon: 2050
*The Delphi survey was originally developed as a technological forecasting technique, which aimed at reaching consensus over relevant technological developments. Nowadays, Delphi expanded into a variety of modified approaches. However, at its core Delphi stands out as a reliable method in situations where individual judgements must be tapped and combined to address an incomplete state of knowledge. Delphi is based on anonymous opinions of experts who are fed back the results of a round-based survey, allowing these experts to rethink their judgement and converge to consensus over key identified areas.

Participation in the survey takes approximately 30-60 minutes and your answers will be kept strictly anonymous.
