Research

Our group, Greener Production @ Waterloo addresses the challenges in bridging energy/chemical production processes and sustainability. The goals are:

(a) Utilizing clean and renewable energy resources for power generation and chemical production.

(b) Understanding how energy processes impact the economy, environment, and sustainability.

1. Flexible hybrid energy storage system

We work on flexible hybrid energy storage system for grid-scale energy storage and micro-grids.

Combining different energy storage technologies (e.g., Li-ion battery, hydrogen, and compressed air) to achieve a more sustainable energy storage system: long-term, large scale, fast response, and small footprint.
Using oxygen permeation membranes to facilitate water/carbon dioxide splitting for hydrogen/syngas production at elevated temperatures for chemical energy storage.

2. Cleaner hydrogen production

We investigate cleaner hydrogen production technologies to decarbonize the economy.

Combining gasification and hydrogen separation in a chemically and thermally integrated manner to produce high purity hydrogen with carbon capture at lower energy penalty
Using a mixed ionic-electronic conducting membrane to enhance water splitting for hydrogen production

3. Chemicals with smaller environmental footprint

We develop technologies for value added chemicals from methane, carbon dioxide and water, such as:

Using perovskite oxides replacing precious metal as catalysts for syngas/ethylene production from methane
Combining methanation and H₂O/CO₂ co-electrolysis in one reactor unit to achieve better efficiency
