Because the world grapples with the pressing have to 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 Power Transitions group is taken with creating 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 information and analytical instruments essential to assist accelerated power transitions in developed economies just like the U.S. in addition to rising market and creating financial system nations within the world south which might 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 techniques,” Mallapragada says. His workforce 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 recent power grids.
“Power techniques will not be static,” he emphasised. “What may be a super design goal right this moment might 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 improvement.”

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.
“For electrolysis to provide low-carbon hydrogen, the electrical energy used should be clear,” he defined. “This raises questions concerning the demand for clear electrical energy and its influence on grid decarbonization. Does this new demand speed up or hinder our potential 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 presently. Scaling these techniques to satisfy world decarbonization targets might require considerably increasing materials provide chains.
“We study the availability chains of recent processes to judge 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 improvement of different applied sciences that stability effectivity, scalability, and useful resource availability.”
Not like 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 example, if a brand new catalyst performs nicely however depends on uncommon supplies, his workforce evaluates its viability from each value and sustainability views. This method 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 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 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 techniques that meet these calls for whereas decreasing carbon emissions.
Mallapragada highlights two main decarbonization methods: using renewable liquid fuels, corresponding to these derived from biomass, and electrification, which may be applied by battery-powered techniques 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 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 elements.
Hydrogen stands out on account of its power density by mass, making it a gorgeous choice 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 techniques. 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 techniques for flights of 1000 nmi or much less (e.g. New York to Chicago), which signify 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 influence on hydrogen manufacturing. The incremental demand from regional aviation might considerably enhance the entire hydrogen required in a decarbonized financial 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 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 workforce’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 certain that innovation is just not solely doable however sensible.
