Because the world grapples with the pressing have to transition to cleaner vitality programs, 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 Vitality Transitions group is taken with growing mathematical modeling approaches to investigate low-carbon applied sciences and their vitality 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 vitality transitions in developed economies just like the U.S. in addition to rising market and growing economic 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 vitality applied sciences, making certain they match seamlessly into quickly evolving vitality programs,” 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 vitality grids.
“Vitality programs are usually not static,” he emphasised. “What could be a great design goal as we speak might shift tomorrow. Our aim is to supply 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 through water electrolysis—a course of that guarantees low-carbon hydrogen however comes with a singular 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 influence on grid decarbonization. Does this new demand speed up or hinder our capacity 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 treasured metals like iridium, which aren’t solely costly but additionally are produced in small quantities at present. Scaling these programs to satisfy world decarbonization targets might 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 mentioned. “This evaluation interprets into tangible targets for researchers, guiding the improvement of other 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 group 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 vitality consumption, or minimizing useful resource dependency.
Aviation presents a very difficult sector for decarbonization on account 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 gas that minimizes quantity and weight. Presently, 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 programs that meet these calls for whereas decreasing carbon emissions.
Mallapragada highlights two major decarbonization methods: the usage of renewable liquid fuels, equivalent to these derived from biomass, and electrification, which might be carried out by means of battery-powered programs or hydrogen gas. Whereas electrification has garnered important curiosity, it stays in its infancy for aviation purposes. 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 required propulsion applied sciences.
Mallapragada’s analysis examined particular energy required to realize zero payload discount and Payload discount required to satisfy variable goal gas cell-specific energy, amongst different elements.
Hydrogen stands out on account of its vitality density by mass, making it a sexy possibility for weight-sensitive purposes 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 sturdy and heavy storage programs. These storage challenges, coupled with the necessity for superior gas cells with excessive particular energy densities, pose important boundaries to scaling hydrogen-powered aviation.
Mallapragada’s analysis on hydrogen use for aviation targeted on the efficiency necessities of on-board storage and gas cell programs 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 programs and gas cells to make sure payload capacities stay unaffected. Present applied sciences for these programs 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 improve the whole hydrogen required in a decarbonized economic system. Producing this hydrogen, significantly by means of electrolysis powered by renewable vitality, would place further 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 group’s analysis serves as a crucial bridge between scientific discovery and societal transformation.
As the worldwide vitality system evolves, researchers like Mallapragada are illuminating the trail ahead—serving to make sure that innovation just isn’t solely attainable however sensible.
