Mohsen Rabbani is a PhD student specializing in mining and metallurgical engineering at the University of Nevada-Reno. 

Mohsen’s research project offered him the opportunity to advance his central PhD thesis project “Sustainable and Cost-Effective Phytoremediation Technologies in the Management of Contaminated Soils Adjacent to a Coal Combustion Product Impoundment." This project involves analyzing suitable plant species for the removal of heavy metals and remediation of a polluted site with coal fly ash. These plant species can be used for the remediation of either abandoned coal mining sites or coal refuse tailing dams. Mohsen hopes to use this new concept for eliminating environmental problems associated with the coal industry, which would be a first in the state of Nevada.

Coal power plants are used to generate electricity and can also cause environmental issues like coal fly ash, a byproduct of the coal burning process that consists of ultra-fine particles containing heavy metals. These metals can pollute soil and water, enter the food chain, and pose severe health risks for humans and the ecosystem. Mohsen’s research introduces phytoremediation to minimize the risks. Phytoremediation is a process using plant species to remove heavy metals through photosynthesis, which absorb carbon dioxide and sun energy to produce energy and oxygen. 

Mohsen’s research has been characterized as a net-zero greenhouse gas emissions pathway and a suitable process to direct carbon capturing, which is aligned with the current approach to address carbon removal concerns. His research will be beneficial for the energy (coal) industry, ecosystem, and communities, with direct long-term effects of increasing overall quality of life. It is also possible to commercialize this project as an extensive-scale application that can be used for direct carbon capturing.

Through the UCR program, Mohsen believes researchers have more time and opportunities to collaborate as advanced manufacturing, cybersecurity, intelligent data analytics, and high-performance computing is integrated into fossil plants of the future.
