Process heat applications make up a large potential market for renewable energy. Despite heating demand being approximately double that of electricity, relatively little work has been done to develop renewable energy for process heat applications. Concentrated solar thermal (CST) systems are capable of reaching temperatures necessary for industrial and commercial steam applications but are often overlooked due to the difficulty of competing with natural gas. Novel hybrid photovoltaic/thermal systems (PV/T) are capable of simultaneously generating electricity and heat. The electricity produced is of higher value and offsets the lifetime cost of the system by producing a cost savings to the facility, ultimately making solar heat competitive with natural gas, propane, coal, and other fuels. The design and economic feasibility of a dish concentrator PV/T (CPV/T) system utilizing a transmissive CPV array is explored through a techno-economic model including technical, financial, and geographical inputs. Through practical design choices, the levelized cost of heat (LCOH) is competitive with natural gas or could even be reduced to zero in some locations by factoring in the electricity savings from additional energy generated by the transmissive CPV module.
