Because the world grapples with the pressing must transition to cleaner power techniques, 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 gentle on the intricate interaction between innovation, scalability, and real-world implementation.
Mallapragada’s Sustainable Power Transitions group is excited about growing mathematical modeling approaches to investigate low-carbon applied sciences and their power system integration beneath completely 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 economic system international locations within the world south which are 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 techniques,” Mallapragada says. His staff makes use of subtle simulation and modeling instruments to handle a twin problem: scaling scientific discoveries from the lab whereas adapting to the dynamic realities of contemporary power grids.
“Power techniques will not be static,” he emphasised. “What could be a perfect design goal at the moment may shift tomorrow. Our purpose is to offer stakeholders—whether or not policymakers, enterprise capitalists, or trade 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 distinguished 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.
“For electrolysis to provide low-carbon hydrogen, the electrical energy used have to be clear,” he defined. “This raises questions concerning the demand for clear electrical energy and its affect on grid decarbonization. Does this new demand speed up or hinder our means to decarbonize the grid?”
Moreover, on the gear stage, challenges abound. Electrolyzers that may function flexibly, to make the most of intermittent renewables like wind and photo voltaic, typically depend on valuable metals like iridium, which aren’t solely costly but additionally are produced in small quantities at the moment. Scaling these techniques to satisfy world decarbonization targets may require considerably increasing materials provide chains.
“We study the provision chains of recent processes to guage how valuable steel 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 growth 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 determine early-stage constraints, whether or not they stem from materials provide chains or manufacturing prices, that would hinder scalability,” he mentioned.
As an illustration, if a brand new catalyst performs effectively however depends on uncommon supplies, his staff evaluates its viability from each price and sustainability views. This method informs researchers about the place to direct their efforts—be it enhancing selectivity, decreasing power consumption, or minimizing useful resource dependency.
Aviation presents a very difficult sector for decarbonization as a consequence of 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 the moment, that is achieved utilizing gasoline 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 techniques that meet these calls for whereas decreasing carbon emissions.
Mallapragada highlights two major decarbonization methods: the usage of renewable liquid fuels, comparable to these derived from biomass, and electrification, which will be carried out by battery-powered techniques or hydrogen gasoline. Whereas electrification has garnered vital curiosity, it stays in its infancy for aviation functions. Hydrogen, with its excessive power per mass, holds promise as a cleaner different. Nevertheless, substantial challenges exist in each the storage of hydrogen and the event of the required propulsion applied sciences.
Mallapragada’s analysis examined particular energy required to attain zero payload discount and Payload discount required to satisfy variable goal gasoline cell-specific energy, amongst different components.
Hydrogen stands out as a consequence of its power density by mass, making it a pretty possibility for weight-sensitive functions like aviation. Nevertheless, storing hydrogen effectively on an plane requires both liquefaction, which calls for excessive cooling to -253°C, or high-pressure containment, which necessitates strong and heavy storage techniques. These storage challenges, coupled with the necessity for superior gasoline cells with excessive particular energy densities, pose vital obstacles to scaling hydrogen-powered aviation.
Mallapragada’s analysis on hydrogen use for aviation targeted on the efficiency necessities of on-board storage and gasoline cell techniques for flights of 1000 nmi or much less (e.g. New York to Chicago), which symbolize a smaller however significant section of the aviation trade. The analysis recognized the necessity for advances in hydrogen storage techniques and gasoline cells to make sure payload capacities stay unaffected. Present applied sciences for these techniques would necessitate payload reductions, resulting in extra frequent flights and elevated prices.

A pivotal consideration in adopting hydrogen for aviation is the upstream affect on hydrogen manufacturing. The incremental demand from regional aviation may considerably enhance the entire hydrogen required in a decarbonized economic system. Producing this hydrogen, notably by 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 staff’s analysis serves as a crucial bridge between scientific discovery and societal transformation.
As the worldwide power system evolves, researchers like Mallapragada are illuminating the trail ahead—serving to be certain that innovation is just not solely doable however sensible.
