SET Plan Deep Geothermal  Implementation Working Group

In the SET plan, Europe has set its renewable energy ambitions, including for geothermal. A specific geothermal Implementation plan has been released and is now executed. In order to reach the goals of placing Europe at the forefront of the low carbon energy scene, an Implementation Working Group (IWG) is created to move forward the Deep Geothermal Implementation Plan (DG-IP), endorsed by the SET Plan Steering Committee.


A support unit for the Deep Geothermal Implementation Working Group (DG-IWG) has been set up to achieve DG-IWG goals efficiently and productively. The support unit has three main work streams:

1) to provide the DG-IWG with relevant information and data from the various stakeholder groups for the DG-IWG to be able to take decisions on required actions;

2) to promote and organise initiatives to mobilise the geothermal community to implement the actions identified in the implementation plan, e.g.: workshops, brokerages, consortium building and exploitation of RD&I results;

3) provide a secretariat for the DG-IWG for assistance on administrative issues and strategy support.

The Declaration of Intent’s goals are the following:

  • Increase reservoir performance resulting in power demand of reservoir pumps to below 10% of gross energy generation and in sustainable yield predicted for at least 30 years by 2030;                                               

  • Improve the overall conversion efficiency, including bottoming cycle, of geothermal installations at different thermodynamic conditions by 10% in 2030 and 20% in 2050;                                                                   

  • Reduce production costs of geothermal energy (including from unconventional resources, enhanced geothermal systems – EGS, and/or from hybrid solutions which couple geothermal with other renewable energy sources) below 10 €ct/kWhel for electricity and 5 €ct/kWhth for heat by 2025;                                                                           

  • Reduce exploration costs by 25% in 2025, and by 50% in 2050 compared to 2015;                                                                             

  • Reduce the unit cost of drilling (€/MWh) by 15% in 2020, 30% in 2030 and by 50% in 2050 compared to 2015;                                                                                        

  • Demonstrate the technical and economic feasibility of responding to commands from a grid operator, at any time, to increase or decrease output ramp up and down from 60% – 110% of nominal power.

The Implementation Plan identifies eight key R&I actions:  

  • Geothermal heat in urban areas;                                                     

  • Materials, methods and equipment to improve operational availability (high temperatures, corrosion, scaling);                                                                                               

  • Enhancement of conventional reservoirs and deployment of unconventional reservoirs;                                                     

  • Improvement of performance (conversion to electricity and direct use of heat);                                                                       

  • Exploration techniques (including resource prediction and exploratory drilling);                                                                                 

  • Advanced drilling/well completion techniques;                      

  • Integration of geothermal heat and power in the energy system and grid flexibility;                                                            

  • Zero emissions power plants
