Speech title "Clean and Green Thermal Energy Technologies for a Decarbonized Future"

Abstract-Clean thermal energy technologies are playing an increasingly vital role in global decarbonization efforts, particularly in the heating and cooling sectors, which together account for a significant portion of total energy use. This presentation introduces an innovative smart quad-generation system designed to simultaneously deliver electricity, heating, cooling, and potable water through a highly integrated and energy-efficient process. Tailored for tropical regions, the system leverages a smart thermal cascading strategy that recovers and redistributes waste heat to maximize overall system efficiency. Compared to conventional systems, this approach offers up to 30% energy savings and 2 to 4% reductions in CO₂ emissions, making it a promising clean energy solution for both building and industrial applications. Its compact footprint and resource efficiency address critical regional needs, particularly in water-scarce and cooling-intensive environments. Aligned with international clean energy objectives, this work showcases a scalable and impactful approach to strengthening the synergy between energy, water, and environmental sustainability.
