Because the world grapples with the pressing must transition to cleaner energy systems, a rising variety of researchers are delving into the design and optimization of emerging technologies. 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 technologies combine into an evolving vitality panorama, shedding light on the intricate interaction between innovation, scalability, and real-world implementation.
Mallapragada’s Sustainable Energy Transitions group is all in favour of creating mathematical modeling approaches to research low-carbon applied sciences and their vitality system integration underneath completely different policy and geographical contexts. The group’s research goals to create the data and analytical tools essential to assist accelerated vitality transitions in developed economies just like the U.S. in addition to rising market and creating economy nations within the international south which are central to international climate mitigation efforts.
Bridging Analysis and Actuality
“Our group focuses on designing and optimizing rising vitality applied sciences, making certain they fit seamlessly into quickly evolving vitality techniques,” Mallapragada says. His staff makes use of refined simulation and modeling instruments to handle a twin problem: scaling scientific discoveries from the lab whereas adapting to the dynamic realities of contemporary vitality grids.
“Power techniques should not static,” he emphasised. “What could be a really perfect design target right this moment may shift tomorrow. Our aim is to offer stakeholders—whether or not policymakers, venture capitalists, or industry leaders—with actionable insights that information each analysis and coverage growth.”

Mallapragada’s analysis usually makes use of case research as an example the challenges of integrating new applied sciences. One distinguished instance is hydrogen production via 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 electricity used should be clear,” he defined. “This raises questions in regards to the demand for clear electrical energy and its affect on grid decarbonization. Does this new demand speed up or hinder our means 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 solar, usually depend on precious metals like iridium, which aren’t solely costly but in addition are produced in small quantities presently. Scaling these techniques to satisfy international decarbonization objectives may require considerably increasing materials provide chains.
“We look at the availability chains of latest processes to guage how valuable metallic utilization and different performance parameters have an effect on prospects for scaling within the coming many years,” Mallapragada mentioned. “This analysis interprets into tangible targets for researchers, guiding the development of different applied sciences that steadiness efficiency, scalability, and useful resource availability.”
In contrast to colleagues who develop new catalysts or materials, 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 costs, that would hinder scalability,” he mentioned.
For example, if a brand new catalyst performs effectively however depends on uncommon supplies, his staff 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 energy 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 power. The vitality required for takeoff, coupled with the necessity for long-distance flight capabilities, calls for a extremely energy-dense fuel that minimizes quantity and weight. At present, that is achieved utilizing gas turbines 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 techniques that meet these calls for whereas lowering carbon emissions.
Mallapragada highlights two primary decarbonization strategies: the usage of renewable liquid fuels, similar to these derived from biomass, and electrification, which might be carried out by battery-powered techniques or hydrogen fuel. Whereas electrification has garnered vital curiosity, it stays in its infancy for aviation applications. 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.
Mallapragada’s analysis examined particular energy required to attain 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 energy density by mass, making it a pretty possibility for weight-sensitive functions like aviation. Nevertheless, storing hydrogen effectively on an aircraft requires both liquefaction, which calls for extreme cooling to -253°C, or high-pressure containment, which necessitates sturdy and heavy storage techniques. These storage challenges, coupled with the necessity for superior fuel 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 fuel cell techniques 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 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 affect on hydrogen production. The incremental demand from regional aviation may considerably improve the overall hydrogen required in a decarbonized economic system. Producing this hydrogen, notably by electrolysis powered by renewable energy, would place extra calls for on vitality 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 capture 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 objectives.
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 important 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 shouldn’t be solely doable however sensible.
