Because the world grapples with the pressing must transition to cleaner power 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 power applied sciences combine into an evolving power panorama, shedding gentle on the intricate interaction between innovation, scalability, and real-world implementation.
Mallapragada’s Sustainable Power Transitions group is eager about growing mathematical modeling approaches to research low-carbon applied sciences and their power system integration underneath 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 growing financial system nations within the world south which are central to world 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 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 power grids.
“Power programs aren’t static,” he emphasised. “What is perhaps a really perfect design goal at the moment might shift tomorrow. Our aim 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 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 singular set of hurdles.
Moreover, on the gear degree, challenges abound. Electrolyzers that may function flexibly, to make the most of intermittent renewables like wind and photo voltaic, typically depend on valuable metals like iridium, which aren’t solely costly but additionally are produced in small quantities presently. Scaling these programs to fulfill world decarbonization objectives might require considerably increasing materials provide chains.
“We study the provision chains of latest processes to guage how valuable 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 event 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 establish early-stage constraints, whether or not they stem from materials provide chains or manufacturing prices, that would 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 enhancing selectivity, lowering 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 programs that meet these calls for whereas lowering carbon emissions.
Mallapragada highlights two major decarbonization methods: using renewable liquid fuels, equivalent to these derived from biomass, and electrification, which might be applied via battery-powered programs 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 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 components.
Hydrogen stands out as a result of its power density by mass, making it a gorgeous 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 sturdy and heavy storage programs. These storage challenges, coupled with the necessity for superior gasoline 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 gasoline cell programs for flights of 1000 nmi or much less (e.g. New York to Chicago), which signify a smaller however significant phase of the aviation business. The analysis recognized the necessity for advances in hydrogen storage programs and gasoline 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 affect on hydrogen manufacturing. The incremental demand from regional aviation might considerably improve the whole hydrogen required in a decarbonized financial 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 price of hydrogen manufacturing. This systemic perspective underscores the complexity of integrating hydrogen into the aviation sector whereas sustaining broader decarbonization objectives.
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 be sure that innovation shouldn’t be solely potential however sensible.
