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 mild on the intricate interaction between innovation, scalability, and real-world implementation.
Mallapragada’s Sustainable Vitality Transitions group is concerned about creating 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 data and analytical instruments essential to help accelerated power transitions in developed economies just like the U.S. in addition to rising market and creating economic system international locations 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, making certain they match seamlessly into quickly evolving power techniques,” Mallapragada says. His group makes use of refined 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 techniques will not be static,” he emphasised. “What could be an excellent design goal right this moment may shift tomorrow. Our objective is to supply stakeholders—whether or not policymakers, enterprise capitalists, or business leaders—with actionable insights that information each analysis and coverage improvement.”

Mallapragada’s analysis typically makes use of case research for instance 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 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 impression on grid decarbonization. Does this new demand speed up or hinder our skill to decarbonize the grid?”
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 presently. Scaling these techniques to fulfill international decarbonization targets may require considerably increasing materials provide chains.
“We look at 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 stated. “This evaluation interprets into tangible targets for researchers, guiding the improvement 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 establish early-stage constraints, whether or not they stem from materials provide chains or manufacturing prices, that might hinder scalability,” he stated.
As an example, if a brand new catalyst performs nicely however depends on uncommon supplies, his group evaluates its viability from each value and sustainability views. This strategy informs researchers about the place to direct their efforts—be it bettering selectivity, lowering power consumption, or minimizing useful resource dependency.
Aviation presents a very difficult sector for decarbonization on account 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 gas 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 techniques that meet these calls for whereas lowering carbon emissions.
Mallapragada highlights two main decarbonization methods: using renewable liquid fuels, reminiscent of these derived from biomass, and electrification, which could be carried out via battery-powered techniques or hydrogen gas. 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 various. Nonetheless, 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 realize zero payload discount and Payload discount required to fulfill variable goal gas cell-specific energy, amongst different components.
Hydrogen stands out on account of 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 strong and heavy storage techniques. These storage challenges, coupled with the necessity for superior gas cells with excessive particular energy densities, pose important limitations to scaling hydrogen-powered aviation.
Mallapragada’s analysis on hydrogen use for aviation centered on the efficiency necessities of on-board storage and gas 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 business. The analysis recognized the necessity for advances in hydrogen storage techniques and gas 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 impression on hydrogen manufacturing. The incremental demand from regional aviation may considerably improve the whole hydrogen required in a decarbonized economic system. Producing this hydrogen, significantly via 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 value 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 vital 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 shouldn’t be solely doable however sensible.
