Because the world grapples with the pressing must transition to cleaner vitality 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 vitality applied sciences combine into an evolving vitality panorama, shedding gentle on the intricate interaction between innovation, scalability, and real-world implementation.
Mallapragada’s Sustainable Power Transitions group is all in favour of growing mathematical modeling approaches to research low-carbon applied sciences and their vitality system integration beneath completely different coverage and geographical contexts. The group’s analysis goals to create the data and analytical instruments essential to assist accelerated vitality transitions in developed economies just like the U.S. in addition to rising market and growing economic system international locations within the international south which might be central to international local weather mitigation efforts.
Bridging Analysis and Actuality
“Our group focuses on designing and optimizing rising vitality applied sciences, guaranteeing they match seamlessly into quickly evolving vitality methods,” Mallapragada says. His staff 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 vitality grids.
“Power methods usually are not static,” he emphasised. “What may be a really perfect design goal immediately might shift tomorrow. Our purpose is to offer stakeholders—whether or not policymakers, enterprise capitalists, or business leaders—with actionable insights that information each analysis and coverage improvement.”

Mallapragada’s analysis usually makes use of case research for example the challenges of integrating new applied sciences. One outstanding instance is hydrogen manufacturing through water electrolysis—a course of that guarantees low-carbon hydrogen however comes with a singular set of hurdles.
“For electrolysis to supply low-carbon hydrogen, the electrical energy used should 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 potential 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, usually depend on valuable metals like iridium, which aren’t solely costly but additionally are produced in small quantities at present. Scaling these methods to satisfy international decarbonization targets might require considerably increasing materials provide chains.
“We study the availability chains of recent processes to judge how valuable 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 other applied sciences that steadiness 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 establish early-stage constraints, whether or not they stem from materials provide chains or manufacturing prices, that would hinder scalability,” he stated.
As an example, if a brand new catalyst performs properly however depends on uncommon supplies, his staff evaluates its viability from each price and sustainability views. This strategy informs researchers about the place to direct their efforts—be it bettering selectivity, lowering vitality consumption, or minimizing useful resource dependency.
Aviation presents a very difficult sector for decarbonization because of its distinctive vitality calls for and stringent constraints on weight and energy. The vitality 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 fuel generators powered by conventional aviation liquid fuels.
“The vitality required for takeoff units a minimal energy requirement,” he famous, emphasizing the technical hurdles of designing propulsion methods that meet these calls for whereas lowering carbon emissions.
Mallapragada highlights two major decarbonization methods: using renewable liquid fuels, resembling these derived from biomass, and electrification, which might be applied by means of battery-powered methods or hydrogen gasoline. Whereas electrification has garnered vital curiosity, it stays in its infancy for aviation functions. Hydrogen, with its excessive vitality per mass, holds promise as a cleaner different. Nevertheless, substantial challenges exist in each the storage of hydrogen and the event of the mandatory propulsion applied sciences.
Hydrogen stands out because of its vitality density by mass, making it a beautiful choice 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 methods. These storage challenges, coupled with the necessity for superior gasoline cells with excessive particular energy densities, pose vital boundaries 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 methods for flights of 1000 nmi or much less (e.g. New York to Chicago), which characterize a smaller however significant phase 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 affect on hydrogen manufacturing. The incremental demand from regional aviation might considerably improve the overall hydrogen required in a decarbonized economic system. Producing this hydrogen, significantly by means of electrolysis powered by renewable vitality, would place extra calls for on vitality 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 staff’s analysis serves as a essential bridge between scientific discovery and societal transformation.
As the worldwide vitality system evolves, researchers like Mallapragada are illuminating the trail ahead—serving to be sure that innovation just isn’t solely doable however sensible.
