In the ever-evolving landscape of energy and environmental priorities, aviation stands out as a sector both vital and infamously challenging to decarbonize. Its deep-rooted dependence on fossil fuels poses a significant hurdle for climate goals, especially for rapidly developing economies with growing air traffic demands like India. Tackling aviation emissions requires innovative fuels and technologies that can integrate seamlessly into existing infrastructure while meeting stringent performance standards. Against this backdrop, the recent strategic partnership between Honeywell, a pioneer in refining technology, and NTPC Green Energy, a leader in renewable energy and green hydrogen in India, signals a potentially transformative step toward sustainable aviation fuel (SAF) production domestically.
Honeywell’s involvement brings its cutting-edge eFining process to the table, a proprietary technology designed to refine diverse feedstocks into SAF that complies with rigorous industry requirements. On the other side, NTPC Green Energy offers robust renewable energy assets, including expansive plans for a Green Hydrogen Hub supported by up to 7 gigawatts of renewable power capacity. The union of these strengths is poised to pioneer pathways for producing SAF at scale while aligning tightly with India’s ambitious clean energy targets and commitments under the Paris Agreement.
A cornerstone of this collaboration is a memorandum of understanding (MoU) signed in April 2025, which sets in motion a feasibility study assessing the viability of creating SAF using a novel carbon capture and utilization pathway. The process being examined involves combining carbon dioxide emissions from NTPC’s thermal power plants with green hydrogen generated via renewable-powered electrolysis. This mixture can be transformed into methanol before being processed into jet fuel through Honeywell’s methanol-to-jet technological approach. Such integration could pioneer a scalable, circular carbon economy, turning greenhouse gases traditionally viewed as pollutants into valuable aviation fuel.
Green hydrogen’s role in this equation cannot be overstated. Produced entirely with renewable electricity, green hydrogen contributes a zero-carbon energy carrier capable of substituting fossil fuels in energy-intensive sectors like aviation. NTPC’s commitment to building an expansive Green Hydrogen Hub encompassing approximately 1,200 acres reflects India’s broader strategy toward upgrading its energy infrastructure for sustainability and self-reliance. This synergy of renewable electricity, hydrogen production, and carbon capture could underpin an SAF supply chain that supports not only aviation’s decarbonization but also the wider industrial ecosystem.
Simultaneously, India’s clean energy transition adds further weight to the partnership’s potential impact. The country has committed to increasing its renewable energy capacity substantially while aiming for net-zero carbon emissions by 2070. Producing sustainable aviation fuel domestically addresses two persistent challenges: reducing dependence on imported fossil jet fuels subject to volatile global markets, and cutting the greenhouse gases emitted by one of the fastest-growing emissions sectors globally. SAF provides a viable near- to mid-term bridge by enabling blending with conventional jet fuel, thereby lowering lifecycle carbon emissions without requiring costly aircraft modifications.
Beyond environmental benefits, establishing a scalable SAF production system could generate significant economic and strategic advantages. The anticipated feasibility study, slated for completion by mid-2025, could lay the groundwork for industrial-scale facilities capable of producing millions of tonnes of SAF per year. This scale-up potential would not only spur the creation of a green fuel market within India but also open avenues for green chemical by-products, infrastructure development, and workforce skill enhancement. These developments would strengthen India’s energy sovereignty by reducing fuel import dependence and cultivating technological expertise in a critical emerging industry.
Moreover, the Honeywell-NTPC collaboration echoes a global shift toward cleaner aviation fuels. Internationally, governments and industry leaders are increasingly viewing SAF as a critical element in comprehensive strategies to mitigate aviation’s carbon footprint. Honeywell’s proven eFining technology, which adapts conventional and novel feedstocks into drop-in SAF compatible with existing engine and fueling networks, stands as a promising piece of this puzzle. Coupled with NTPC Green Energy’s renewable generation and carbon management capabilities, the partnership embodies a holistic approach—melding technological innovation, renewable power, and carbon utilization—to combat climate change from an aviation perspective.
In essence, the partnership between Honeywell and NTPC Green Energy represents a landmark initiative to bring sustainable aviation fuel production to India, aligned with the country’s environmental goals and energy security ambitions. Leveraging proprietary refining processes and extensive renewable resources, the collaboration is not only exploring technical feasibility but also modeling how emerging economies can craft tailored, circular energy solutions to advance decarbonization. Should these efforts successfully scale, they may well herald an era when sustainable fuels become an integral component of flight operations, fueling not only planes but a global transition to lower-carbon transportation. This venture exemplifies how innovation and strategic collaboration can help rewrite the future of aviation—one flight at a time.
