Summary

The talk, presented by Mojo Moala, a PhD student at the University of Alberta, focuses on the potential of concentrated solar thermal (CST) to decarbonize industrial heat. It begins by highlighting the urgent need to reduce industrial emissions, which account for a significant portion of global CO2 output, with heat being a major energy use. The speaker explains the basics of solar energy, distinguishing between photovoltaic (PV) panels that use light and CST that uses heat. He describes the core concept of CST: using mirrors to concentrate sunlight onto a receiver, heating a heat transfer fluid like molten salts. The talk covers different CST configurations, with tower systems being the most common, and emphasizes the importance of heliostat optical accuracy. The speaker also touches on the physics of heat transfer, including radiation, conduction, and convection, and introduces the concept of volumetric receivers as an advanced technology. The presentation includes a historical anecdote about Archimedes’ heat ray, illustrating the long-standing idea of using concentrated sunlight. The speaker concludes that clean heat is key to decarbonizing industry and that CST offers a promising solution, though challenges remain in implementation and efficiency.
