Research Vision

Our lab investigates sustainable catalysis and separations processes. We aim to develop new materials and technologies, which address challenges at the forefront with the food-energy-water nexus.

Distributed Ammonia

How will the world produce more food from less land while minimizing waste and energy? With increasing world population, biofuel production, protein rich diets, and decreasing arable land, agricultural productivity has come to the forefront in discussions regarding global hunger.  To address world hunger, current estimates suggest that the production of food over the next 40 years will need to equal the production of food over last 8000 years. 

Improving agricultural yields requires small-scale technologies, which are capable of controlling the growing environment and monitoring the health of an individual plant.



We are investigating sustainable catalytic (photo and electrochemical) approaches to convert nitrogen into ammonia using only air, water, and solar energy. We are also using machine learning and physics based models to assess the environmental cost of centralized and distributed ammonia (fertilizer) production.

Electrocatalysis for Water and Energy

With electricity prices decreasing, there is a growing interest to develop new ways to convert this cheap and carbon free electricity into valuable products. Electrocatalysis provides a route to use electricity to perform catalytic processes, which today can only be accomplished using thermal energy and fossil fuels. We aim to design and synthesize electrocatalyst, which contain a high degree of activity for a desired reaction. Currently, we are exploring electrocatalyst, which can be used for environmental remediation (nitrate reduction), and energy production (oxygen reduction, nitrate reduction, nitrogen reduction, CO2 reduction). Our goal is to aid in the development to electrofuels and electrified water remediation technologies.

Desalination

Water scarcity because of drought, overuse, and climate change affects nearly 20% of the world’s population. It results in the need for widespread adoption of desalination systems. By 2050, the supply of desalinated water could increase to 192 million m^3/day to accommodate population and water demand growth. Today, nearly all (~99%) desalination plants rely on fossil fuels as the primary energy source for the production of heat or electricity. If this trend continues, carbon emissions from fossil fuel-powered desalination plants could increase to 400 million tons of CO_2 per year by 2050. The waste brine produced at desalination plants is also projected to increase to 240 km3 per year by 2050 (half the volume of Lake Erie). This prompts a strong need to explore strategies for developing renewable driven desalination plants with reduced waste (CO2 and brine) production. We are using machine learning and physics based models to investigate the critical energetic, economic, and environmental performance metrics for solar-desalination systems.

Sustainable Energy Systems

In order to reduce capital costs of concentrated solar power (CSP) plants by 50% and achieve the goals set by the DOE, the performance of each material must be improved  and the manufacturing costs of each component must be decreased.  We believe  that both of these aims can be met if thermal transport properties of particulate packed-bed reactors and heat transfer media (HTM) can be mapped with a high degree of accuracy under thermally relevant conditions.  Moving packed-bed heat exchangers could replace fluidized-bed heat exchangers, which require expensive pumps and recuperators. these packed-beds.  We are beginning to address this challenge using in-situ x-ray based tomography, which can map the structural interactions between particles.

Battery Recycling

A circular economy for batteries is critical to enable widespread adoption of electric vehicles and grid energy storage. However, the main bottleneck is the lack of recycling. The LIB collection rate is 10-20%, and lithium recovery is only at ~1%. This is because current LIB recycling processes mirror nickel–cadmium, lead acid, and nickel metal hydride recycling processes, which rely on physical separations coupled with pyrometallurgy and hydrometallurgy. Physical separations, largely consist of processes established in the mineral processing industry, and include crushing, grinding, magnetic, electrostatic and gravity based separations. These physical separations require low energy, but are process intensive. Crushing and sorting each battery component individually is not possible, and therefore all battery components (anode, cathode, and electrolyte) are mixed and recycled together. Mixing all resources together results in the need for excesses separations which adds to the energy demand, results in low material recovery, and low purity. We are examine how to electrify battery recycling to recover critical components. We are also examining specific challenges which may arise with new battery formulations.
