“…Finally, we compare our IRS to existing CSP plants: the Solar One in California (Kolb et al, 1991), the 100 MWhth TES system in Ait Baha (Zanganeh et al, 2014c), and the CSPonD in Masdar (Gil et al, 2017), based on our results. The comparison is done against ηabsorb, ηcharging, ηdischarging, and ξcycle shown in Table 6.…”

Concentrating solar power systems (CSP) with thermal storage units can provide dispatchable power. Here we propose a new modified design of a cavity receiver combined with a thermocline heat storage unit for the beam-down CSP. Instead of using a separate receiver and heat storage unit, an integrated unit consisting of an extended cylindrical cavity with a packed bed storage is proposed. The new approach was designed using validated cavity radiation and quasi-1D 2-phase numerical heat transfer models. As the concentrated irradiation can be directly absorbed in such a system, the structure used can be simplified and operation of the unit is more effective.A high solar-to-exergy conversion ratio of 0.52 was reached with an optimized design, charging and discharging efficiencies being well beyond 99% and 92% at 770℃. An important detail in the integrated receiver-storage design was the use of a circulation air flow fan, which enhanced the heat transfer inside the packed bed storage. The proposed new design is promising for improving the efficiency and economics of beam down CSP.
