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 fascinated by growing mathematical modeling approaches to investigate low-carbon applied sciences and their power system integration below completely different coverage and geographical contexts. The group’s analysis goals to create the information 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 nations within the international south which can be central to international 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 group 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 recent power grids.
“Vitality methods usually are not static,” he emphasised. “What is likely to be an excellent design goal right now may shift tomorrow. Our aim 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 as an example the challenges of integrating new applied sciences. One distinguished instance is hydrogen manufacturing through water electrolysis—a course of that guarantees low-carbon hydrogen however comes with a novel set of hurdles.
“For electrolysis to supply low-carbon hydrogen, the electrical energy used should be clear,” he defined. “This raises questions in regards to the demand for clear electrical energy and its affect on grid decarbonization. Does this new demand speed up or hinder our skill to decarbonize the grid?”
Moreover, on the tools stage, 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 additionally are produced in small quantities at present. Scaling these methods to fulfill international decarbonization targets may require considerably increasing materials provide chains.
“We study the availability chains of recent processes to judge how treasured steel utilization and different efficiency parameters have an effect on prospects for scaling within the coming a long time,” Mallapragada mentioned. “This evaluation interprets into tangible targets for researchers, guiding the growth of different applied sciences that steadiness 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 might hinder scalability,” he mentioned.
As an illustration, if a brand new catalyst performs effectively however depends on uncommon supplies, his group 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.
Aviation presents a very difficult sector for decarbonization as a result 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. Presently, 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 methods that meet these calls for whereas decreasing carbon emissions.
Mallapragada highlights two major decarbonization methods: using renewable liquid fuels, resembling these derived from biomass, and electrification, which might be carried out by way of battery-powered methods or hydrogen gasoline. Whereas electrification has garnered vital curiosity, it stays in its infancy for aviation purposes. Hydrogen, with its excessive power per mass, holds promise as a cleaner various. 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 realize zero payload discount and Payload discount required to fulfill variable goal gasoline cell-specific energy, amongst different elements.
Hydrogen stands out as a result of its power density by mass, making it a beautiful 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 strong and heavy storage methods. These storage challenges, coupled with the necessity for superior gasoline cells with excessive particular energy densities, pose vital limitations 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 symbolize a smaller however significant phase of the aviation trade. 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 affect on hydrogen manufacturing. The incremental demand from regional aviation may considerably improve the whole hydrogen required in a decarbonized economic system. Producing this hydrogen, notably by way of electrolysis powered by renewable power, would place further calls for on power grids and necessitate additional infrastructure enlargement.
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 group’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 make sure that innovation just isn’t solely doable however sensible.
