Multi-scale Optimization of Carbon Capture and Conversion System

In the context of achieving net-zero emission of greenhouse gases, carbon capture technology is very important before the widespread adoption of renewable generation. We study optimization of carbon capture and conversion systems to minimize the overall system costs. This involves the optimization of both molecular structures and process design/operating conditions.

Advancing Decarbonization with a Flexible Operation of Membrane-based Carbon Capture

The membrane-based carbon capture technology has raised attention as an efficient approach for capturing carbon dioxide from flue gas without requiring large-scale investments. Given the variability in electricity prices associated with the growing contribution of renewable energy and carbon emission regulations, it is important to develop a flexible operation strategy for carbon capture processes. We aim to develop a framework for dynamic optimization of a power plant-membrane-based carbon capture-electric grid system. 

Optimization of Clean Hydrogen System

Clean hydrogen is considered as a key energy source for achieving carbon neutralization. We develop a framework for optimizing clean hydrogen production networks by optimally balancing green (hydrogen production via electrolysis of water using renewable energy) and blue hydrogen (hydrogen production via natural gas reforming and carbon capture) productions. A data-driven approach can enhance the convergence performance and computational efficiency of complex process systems.
