In this compelling episode, we sit down with Dr. Singh to discuss the future of sustainable energy via an artificial photosynthetic (AP) system. Dr. Singh guides us through the fascinating concept of artificial photosynthesis, highlighting the challenges and opportunities of capturing CO2 directly from dilute sources such as flue gas and air to produce fuels and chemicals.

Delving into the core of his research, Dr. Singh introduces us to the design and evaluation of an integrated AP system that harnesses sunlight to convert captured CO2 into fuels. His work explores the solar-to-fuel (STF) efficiency of such a system, revealing promising thermodynamic limits ranging from 34% to 40% for a variety of products.

The conversation deepens as Dr. Singh describes two different integration schemes—integrated cascade systems and fully integrate ...
