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 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 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 Energy Transitions group is keen on growing mathematical modeling approaches to investigate low-carbon applied sciences and their power system integration below totally 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 growing financial system international locations within the world south which might be central to world climate 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 workforce makes use of subtle simulation and modeling instruments to deal with a twin problem: scaling scientific discoveries from the lab whereas adapting to the dynamic realities of contemporary power grids.
“Vitality programs usually are not static,” he emphasised. “What is likely to be a great design goal at the moment may shift tomorrow. Our objective is to offer stakeholders—whether or not policymakers, venture capitalists, or trade leaders—with actionable insights that information each analysis and coverage growth.”

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 novel set of hurdles.
“For electrolysis to supply low-carbon hydrogen, the electrical energy used have to 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 potential 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, usually depend on precious metals like iridium, which aren’t solely costly but additionally are produced in small quantities at the moment. Scaling these programs to satisfy world decarbonization targets may require considerably increasing materials provide chains.
“We study the availability chains of latest processes to guage how valuable metallic 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 event of other applied sciences that stability effectivity, scalability, and useful resource availability.”
In contrast to 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 nicely however depends on uncommon supplies, his workforce evaluates its viability from each price 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 as a consequence 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 gas that minimizes quantity and weight. At present, that is achieved utilizing gas turbines 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 decreasing carbon emissions.
Mallapragada highlights two primary decarbonization strategies: the usage of renewable liquid fuels, akin to these derived from biomass, and electrification, which will be applied via battery-powered programs or hydrogen fuel. 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 realize zero payload discount and Payload discount required to satisfy variable goal gas cell-specific energy, amongst different elements.
Hydrogen stands out as a consequence of its energy density by mass, making it a pretty 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 programs. These storage challenges, coupled with the necessity for superior fuel cells with excessive particular energy densities, pose important obstacles 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 programs for flights of 1000 nmi or much less (e.g. New York to Chicago), which symbolize a smaller however significant section 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 affect on hydrogen production. The incremental demand from regional aviation may considerably enhance the full hydrogen required in a decarbonized financial system. Producing this hydrogen, notably via electrolysis powered by renewable energy, would place further 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 capture 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 workforce’s analysis serves as a crucial bridge between scientific discovery and societal transformation.
As the worldwide power system evolves, researchers like Mallapragada are illuminating the trail ahead—serving to make sure that innovation isn’t solely attainable however sensible.
