As the world shifts towards cleaner energy systems, NYU Tandon's Assistant Professor Dharik Mallapragada is at the forefront of designing and optimizing emerging technologies for sustainable energy transitions. His group focuses on mathematical modeling of low-carbon technologies, including hydrogen production via water electrolysis, to support energy system integration under various contexts. The research aims to provide insights for policymakers, investors, and industry leaders to guide research and policy development. Mallapragada's work explores the challenges of scaling scientific discoveries like hydrogen production, emphasizing the importance of clean electricity, material supply chains, and performance parameters. Additionally, his research delves into decarbonizing aviation, highlighting the technical hurdles of designing propulsion systems using renewable fuels, electrification, and hydrogen. While hydrogen shows promise due to its energy density, storage challenges and propulsion technology development present barriers to scaling its use in aviation.
