Including seismic risk mitigation measures into the Levelized Cost Of Electricity in enhanced geothermal systems for optimal siting

摘要: Abstract The seismic risk associated with deep fluid injection in Enhanced Geothermal Systems can be mitigated by stopping reservoir stimulation when the becomes unacceptable or reducing production flow rates seismicity occurs during operational phase. So far, none of these mitigation measures have been included Levelized Cost Of Electricity. A meta-model is introduced that estimates optimal price electricity, based on an analytical geothermal energy model, and updates this cost to include outlay for mandatory measures. proposed model computes both electricity heat credit. costs added are probability abandoning well, a traffic-light system, defined as ratio scenarios exceed given safety threshold space. In phase, net generated reduced clipping rate so reservoir's overpressure does not regional minimum effective stress. Based generic triplet, we investigate trade-off between credit cost. cost, mostly due financial aversion, shifts site plant from few kilometres tens away populated areas, increasingly vulnerable building stocks. Finally, using simple yet realistic optimisation strategy, study role standard plays determining number EGS plants sited region.
