Definition and success criteria for flexible geothermal ORC

This deliverable refers to Task(s) 1.1 and 1.2While collaborating with the grid operator, the KPIs as defined in section 1.1 for the ancillary services will be reviewed.ZOREN will define time span and frequency of demonstration to minimize the interruption of the energy supply to the grid.With support of VITO, NALDEO, FRAUNHOFER and TVS, ZOREN will define the specification of the thermal energy storage (TES), absorption chiller and heat exchanger (HX) for the demonstration case 1. ZOREN will also define the specification for full scale implementation of nGEL concept at ZOREN site. TVS, with the support from ZOREN and REPG will define the specification of the recuperator and HX and cold thermal energy storage (CTES) for the demonstration case 2.ZOREN will lead the task to do a documented risk analysis and safety case, confirming the safe condition is within the proposed operating envelope of materials behaviour in the anticipated pressure, temperature and environment regimes.
