Hybrid PV solutions for industrial and household heating systems
Heating represents close to 50% of global energy demand. In industry, over 70% of the final energy used is for heat. In the building sector, this number is closer to 80%. In industry, 90% of heat sources are fossil fuels, while in buildings it is closer to 60%. In this work, we discuss hybrid photovoltaic (PV) solutions to accelerate the decarbonization of industrial and household heating for temperature regimes below 150°C, which represent 30% of industrial heating needs and almost the entirety of household needs. Concerning industrial heating, we discuss a solar hybrid system from a techno-economic perspective to produce steam for the food and beverage industries, where we combine parabolic solar collectors with pressurized water thermal storage and PV with high-temperature sand storage, demonstrating economically competitive solar fractions as high as 90%. For household hybrid heating systems, we summarize our results on system performance assessment of PV, heat pump, and thermal storage hybrid systems, including the latest results on the optimization of a accelerated laboratory system test method to forecast annual energy performance.
