<\/span>Silicon Tetrachloride (SiCl4<\/sub>) is proposed as a new potential working fluid for high-temperature Rankine Cycles. The capability to overcome the actual thermal stability limit of fluids commercially employed in the state-of-the-art Organic Rankine Cycles (ORC) is demonstrated by static thermal stability and material compatibility tests. Experimental static test proves its thermo-chemical stability with a conventional stainless-steel alloy (AISI 316L) up to 650\u202f\u00b0C. A preliminary material compatibility analysis performed with optical microscope on the AISI 316L cylinder, after exposure of 300\u202fh to SiCl4<\/sub> at temperature higher than 550\u202f\u00b0C, confirms the potentiality of this fluid when coupled with high-grade heat sources. A thermodynamic analysis has been carried out accounting for the effect of operating conditions on the axial turbine efficiency. A comparison with fluids adopted in medium\u2013high temperature ORCs is performed, evidencing that the proposed fluid could achieve more than\u202f+\u202f10\u202f% points as thermal efficiency gain compared to any commercial solutions when coupled with high-temperature sources such as solar, biomass, waste heat from industrial processes and prime movers. A 2\u202fMW SiCl4<\/sub> cycle operating full-electric at 550\u202f\u00b0C reaches a thermal efficiency of 38\u202f%, exceeding values attainable by any other working fluid under similar conditions and power size.<\/p>\n
