Because the world grapples with the pressing must transition to cleaner power methods, a rising variety of researchers are delving into the design and optimization of rising applied sciences. On the forefront of this effort is Dharik Mallapragada, Assistant Professor of Chemical and Biomolecular Engineering at NYU Tandon. Mallapragada is devoted to understanding how new power applied sciences combine into an evolving power panorama, shedding mild on the intricate interaction between innovation, scalability, and real-world implementation.
Mallapragada’s Sustainable Vitality Transitions group is eager about growing mathematical modeling approaches to investigate low-carbon applied sciences and their power system integration underneath totally different coverage and geographical contexts. The group’s analysis goals to create the data and analytical instruments essential to help accelerated power transitions in developed economies just like the U.S. in addition to rising market and growing financial system nations within the world south which can be central to world local weather mitigation efforts.
Bridging Analysis and Actuality
“Our group focuses on designing and optimizing rising power applied sciences, guaranteeing they match seamlessly into quickly evolving power methods,” Mallapragada says. His crew makes use of subtle simulation and modeling instruments to deal with a twin problem: scaling scientific discoveries from the lab whereas adapting to the dynamic realities of contemporary power grids.
“Vitality methods aren’t static,” he emphasised. “What may be a great design goal in the present day might shift tomorrow. Our aim is to supply stakeholders—whether or not policymakers, enterprise capitalists, or business leaders—with actionable insights that information each analysis and coverage growth.”

Mallapragada’s analysis typically makes use of case research for instance the challenges of integrating new applied sciences. One outstanding instance is hydrogen manufacturing by way of water electrolysis—a course of that guarantees low-carbon hydrogen however comes with a novel set of hurdles.
Moreover, on the tools degree, challenges abound. Electrolyzers that may function flexibly, to make the most of intermittent renewables like wind and photo voltaic, typically depend on treasured metals like iridium, which aren’t solely costly but in addition are produced in small quantities at present. Scaling these methods to fulfill world decarbonization targets might require considerably increasing materials provide chains.
“We study the availability chains of latest processes to guage how treasured metallic utilization and different efficiency parameters have an effect on prospects for scaling within the coming many years,” Mallapragada mentioned. “This evaluation interprets into tangible targets for researchers, guiding the event of different applied sciences that stability effectivity, scalability, and useful resource availability.”
In contrast to colleagues who develop new catalysts or supplies, Mallapragada focuses on decision-support frameworks that bridge laboratory innovation and large-scale implementation. “Our modeling helps establish early-stage constraints, whether or not they stem from materials provide chains or manufacturing prices, that might hinder scalability,” he mentioned.
As an illustration, if a brand new catalyst performs effectively however depends on uncommon supplies, his crew evaluates its viability from each price and sustainability views. This strategy informs researchers about the place to direct their efforts—be it bettering selectivity, decreasing power consumption, or minimizing useful resource dependency.
Decarbonizing aviation
Aviation presents a very difficult sector for decarbonization resulting from its distinctive power calls for and stringent constraints on weight and energy. The power required for takeoff, coupled with the necessity for long-distance flight capabilities, calls for a extremely energy-dense gasoline that minimizes quantity and weight. At present, that is achieved utilizing fuel generators powered by conventional aviation liquid fuels.
“The power required for takeoff units a minimal energy requirement,” he famous, emphasizing the technical hurdles of designing propulsion methods that meet these calls for whereas decreasing carbon emissions.
Mallapragada highlights two main decarbonization methods: the usage of renewable liquid fuels, equivalent to these derived from biomass, and electrification, which may be applied by means of battery-powered methods or hydrogen gasoline. Whereas electrification has garnered important curiosity, it stays in its infancy for aviation purposes. Hydrogen, with its excessive power per mass, holds promise as a cleaner different. Nonetheless, substantial challenges exist in each the storage of hydrogen and the event of the mandatory propulsion applied sciences.
Mallapragada’s analysis examined particular energy required to attain zero payload discount and Payload discount required to fulfill variable goal gasoline cell-specific energy, amongst different elements.
Hydrogen stands out resulting from its power density by mass, making it a horny possibility for weight-sensitive purposes like aviation. Nonetheless, storing hydrogen effectively on an plane requires both liquefaction, which calls for excessive cooling to -253°C, or high-pressure containment, which necessitates sturdy and heavy storage methods. These storage challenges, coupled with the necessity for superior gasoline cells with excessive particular energy densities, pose important boundaries to scaling hydrogen-powered aviation.
Mallapragada’s analysis on hydrogen use for aviation centered on the efficiency necessities of on-board storage and gasoline cell methods for flights of 1000 nmi or much less (e.g. New York to Chicago), which characterize a smaller however significant section of the aviation business. The analysis recognized the necessity for advances in hydrogen storage methods and gasoline cells to make sure payload capacities stay unaffected. Present applied sciences for these methods would necessitate payload reductions, resulting in extra frequent flights and elevated prices.

A pivotal consideration in adopting hydrogen for aviation is the upstream influence on hydrogen manufacturing. The incremental demand from regional aviation might considerably improve the full hydrogen required in a decarbonized financial system. Producing this hydrogen, significantly by means of electrolysis powered by renewable power, would place extra calls for on power grids and necessitate additional infrastructure growth.
Mallapragada’s evaluation explores how this demand interacts with broader hydrogen adoption in different sectors, contemplating the necessity for carbon seize applied sciences and the implications for the general price of hydrogen manufacturing. This systemic perspective underscores the complexity of integrating hydrogen into the aviation sector whereas sustaining broader decarbonization targets.
Mallapragada’s work underscores the significance of collaboration throughout disciplines and sectors. From figuring out technological bottlenecks to shaping coverage incentives, his crew’s analysis serves as a essential bridge between scientific discovery and societal transformation.
As the worldwide power system evolves, researchers like Mallapragada are illuminating the trail ahead—serving to be sure that innovation is just not solely doable however sensible.
