Green Aero Secures $1.6M to Propel India's Hydrogen and Defense Engines
In a significant boost for India's burgeoning deep-tech and defense manufacturing sectors, New Delhi-based startup Green Aero has secured $1.6 million in seed funding.[1] The investment round, led by pi Ventures with participation from Antler, will fuel the company's ambitious plans to develop and commercialize advanced aero engines for both defense applications and hydrogen-powered civil aviation.[2][3] This capital injection is earmarked for accelerating research and development, establishing an in-house testing facility, and expanding its team as it pushes towards commercial pilots.[2] The move positions Green Aero as a key player in India's strategic push for self-reliance in critical aerospace technologies, a domain historically dominated by foreign suppliers.[1]
Founded in late 2023 and incubated at the prestigious Indian Institute of Technology (IIT) Delhi, Green Aero is tackling one of the most significant challenges in the aerospace industry: propulsion.[1][3] India has long been dependent on imported turbine engines for everything from drones to fighter jets, a vulnerability that creates strategic and economic pressures.[4][5] Green Aero aims to directly address this gap by building indigenous core propulsion technology. The company's founder, Prithwish Kundu, a former research scientist at the U.S. Department of Energy's Argonne National Laboratory with a history of collaboration with NASA and the U.S. Army, brings a wealth of experience to this complex endeavor.[2][3] The startup's vision is not just to replicate existing technology but to leapfrog it, aiming for propulsion systems that are twice as efficient as current global standards.[6] This focus on efficiency and performance is a cornerstone of their strategy to build world-class aero engines from the ground up in India.[2]
A key differentiator for Green Aero is its dual-pronged approach, targeting both the immediate needs of the defense sector and the future of sustainable aviation with hydrogen power. The company recently achieved a major milestone by test-firing "The Blue Dragon," which it claims is India's first hydrogen-powered aero engine core.[1][3] This success is a significant step towards the long-term goal of commercializing zero-emission engines capable of powering future hydrogen aircraft.[3] While the path to widespread hydrogen aviation is long, with major players like Airbus targeting entry into service in the mid-2030s, Green Aero's focus on defense applications provides a more immediate market.[7][8] This strategic approach allows the company to potentially secure defense contracts to sustain its operations while continuing the long-term development of its hydrogen engine technology.[1] The startup plans to commercialize its first small-category engine within the next 12 months, a crucial step in proving its capabilities and generating revenue.[2][6]
The implications of Green Aero's success extend beyond the company itself and into the broader landscape of Indian industry and global aerospace. The Indian government has been actively promoting indigenous defense manufacturing, with the goal of not only achieving self-reliance but also becoming a significant defense exporter.[9][5] The development of domestic aero engine technology is a critical piece of this puzzle, a challenge that has seen even established government projects face significant delays.[9][10] Green Aero's agile, startup-driven approach could provide a new model for innovation in this sector. Furthermore, the global aviation industry is at a crossroads, grappling with the urgent need to decarbonize. While some companies focus on hydrogen fuel cells, which generate electricity to power motors, Green Aero is betting on hydrogen combustion, which adapts traditional turbine engine technology to burn clean hydrogen fuel.[11][8] This approach may offer a more scalable solution for larger aircraft.[12][8]
In conclusion, Green Aero's $1.6 million funding round is more than just a financial transaction; it is a vote of confidence in India's ability to compete in the high-stakes world of aerospace technology.[1][2] By focusing on both immediate defense needs and the long-term potential of hydrogen propulsion, the startup has carved out a strategic niche.[1] The successful development and commercialization of its "Blue Dragon" engine core and subsequent engine platforms could not only reduce India's reliance on foreign technology but also position it as a leader in the next generation of sustainable aviation.[3] As the company moves from lab-scale prototypes to full engine assemblies, the global aerospace and defense industries will be watching closely to see if this IIT Delhi-incubated startup can truly redefine propulsion technology from India for the world.[2][13]
