Professor Sagar Saren's research lab specializes in sustainable energy systems, with a primary focus on advanced sorption-based thermal cycles for low-grade heat recovery and temperature upgrading. The lab investigates innovative thermodynamic cycles such as adsorption heat transformers (AHT) to enhance energy efficiency and support decarbonization goals. It also explores the application of these technologies in real-world challenges, including pandemic-related energy and infrastructure crises. The research integrates thermodynamic modeling, material characterization, and system optimization for practical deployment in developing and industrialized contexts.

Adsorption heat transformer (AHT) cycle is capable of upgrading the low-grade waste heat to a higher temperature. The maximum temperature lift of the AHT cycle can represent its theoretical performance limit. However, such a metric is currently absent from the literature due to the scarcity of fundamental studies on the heat upgrading sorption cycles. Therefore, in the present study, three models are proposed to derive the ‘maximum temperature lift’ of a typical AHT cycle: (i) heat engine heat p
COVID-19 pandemic shrouded the humanity in the dark clouds of deaths, long term health issues, economic deterioration, and social crisis. Economically developed and developing countries alike faced the wrath of the pandemic severely. India being the 2nd most populated country in the world, having a middle income developing market with sixth largest economy, was no exception. After the US, India secured its position of having the second highest number of cases and deaths across the world, through
