Because the world grapples with the pressing have to transition to cleaner vitality techniques, 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 applied sciences combine into an evolving vitality panorama, shedding gentle on the intricate interaction between innovation, scalability, and real-world implementation.
Mallapragada’s Sustainable Energy Transitions group is all in favour of growing mathematical modeling approaches to research low-carbon applied sciences and their vitality system integration below completely different coverage and geographical contexts. The group’s analysis goals to create the information and analytical instruments essential to help accelerated vitality transitions in developed economies just like the U.S. in addition to rising market and growing financial system nations within the world south which can be central to world climate 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 techniques,” Mallapragada says. His group 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 aren’t static,” he emphasised. “What is likely to be a really perfect design goal at this time might shift tomorrow. Our purpose is to supply stakeholders—whether or not policymakers, venture capitalists, or business leaders—with actionable insights that information each analysis and coverage growth.”

Mallapragada’s analysis typically makes use of case research for example 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.
“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 influence on grid decarbonization. Does this new demand speed up or hinder our capability 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 precious metals like iridium, which aren’t solely costly but additionally are produced in small quantities at present. Scaling these techniques to satisfy world decarbonization objectives might require considerably increasing materials provide chains.
“We look at the availability chains of latest processes to judge how valuable steel utilization and different efficiency parameters have an effect on prospects for scaling within the coming many years,” Mallapragada stated. “This evaluation interprets into tangible targets for researchers, guiding the event of different 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 might hinder scalability,” he stated.
As an example, if a brand new catalyst performs nicely however depends on uncommon supplies, his group evaluates its viability from each value and sustainability views. This strategy informs researchers about the place to direct their efforts—be it enhancing selectivity, decreasing vitality consumption, or minimizing useful resource dependency.
Decarbonizing aviation
Aviation presents a very difficult sector for decarbonization resulting from 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. 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 decreasing carbon emissions.
Mallapragada highlights two primary decarbonization strategies: using renewable liquid fuels, corresponding to these derived from biomass, and electrification, which will be applied via battery-powered techniques or hydrogen fuel. Whereas electrification has garnered vital curiosity, it stays in its infancy for aviation purposes. Hydrogen, with its excessive vitality per mass, holds promise as a cleaner various. 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 attain zero payload discount and Payload discount required to satisfy variable goal gas cell-specific energy, amongst different elements.
Hydrogen stands out resulting from its energy density by mass, making it a horny 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 strong and heavy storage techniques. These storage challenges, coupled with the necessity for superior fuel cells with excessive particular energy densities, pose vital obstacles to scaling hydrogen-powered aviation.
Mallapragada’s analysis on hydrogen use for aviation centered 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 business. 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 influence on hydrogen production. The incremental demand from regional aviation might considerably improve the full hydrogen required in a decarbonized financial system. Producing this hydrogen, significantly via electrolysis powered by renewable energy, 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 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 group’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 make sure that innovation is just not solely attainable however sensible.
