Carbon Negative Geothermal: Techno-Economic Feasibility of Combined Geothermal Energy and Biomass-based Carbon Dioxide Removal for Aotearoa and Beyond

24 November 2023
Main supervisor:

David Dempsey


Rebecca Peer

Research interests:

Karan is interested in Climate Change prevention research, specifically renewable energy and atmospheric carbon dioxide removal. For his PhD, he is investigating both by combining geothermal energy with bioenergy and carbon dioxide removal, a net carbon negative process that increases renewable electricity and removes CO2 from the atmosphere over time.

Karan’s background in geothermal stems from his time at the Geothermal Institute in Auckland, both as a Masters student and Research Assistant. For his Masters project he conducted a numerical simulation of a geothermal field in Türkiye.

Additionally, Karan has studied other sources of energy such as solar, wind hydroelectric and petroleum.

Personal interests:

Karan enjoys volunteering and community service, novel writing, painting, poetry, kayaking, hiking, cycling, wildlife documentaries and playing Magic: the Gathering. He enjoys visiting beautiful parts of Aotearoa that were the film sites for the Lord of the Rings trilogy.
