Abstract: This paper provides a framework to assess the viability of the solar carbothermal route for zinc production by comparing the life cycle energy demand and carbon emissions with the photovoltaic (PV), concentrated solar power (CSP) and grid driven hydrometallurgy systems. The data of the pilot-scale demonstration at Weizmann Institute of Science (WIS) is used to propose a hypothetical design of the 300 kW solar thermochemical plant at Jodhpur, India. A conceptual design of the similar scale PV, CSP, and grid hydrometallurgy plants are developed. The effect of upscaling these technologies to the demonstration and commercial levels is assessed.
