IIT Madras, in collaboration with the Centre for Study of Science, Technology and Policy (CSTEP), has released findings from a new research study. The study provides essential guidance aimed at boosting sustainable green hydrogen production across India. This initiative directly supports India’s ambitious national target of achieving net-zero carbon emissions by 2070 .
The research systematically addresses critical challenges and opportunities within India’s emerging green hydrogen economy. It outlines strategies for securing essential raw materials, proposes a standardized system for hydrogen classification, and details a plan for the sector’s long-term sustainable expansion. These insights were communicated through an official statement from IIT Madras.
Strategic Guidance for Growth
A significant contribution of the study is its proposed tiered classification system for hydrogen. This system introduces four distinct categories: “platinum,” “gold,” “silver,” and “bronze.” The system’s primary goal is to provide a clear, standardized method for communicating the environmental quality and production pathways of different hydrogen types. This transparency is intended to empower policymakers, attract investors, and guide industry stakeholders in their decision-making processes.
Furthermore, the research directly tackles the crucial issue of supply chain resilience. It offers practical guidance for securing the critical raw materials required for Proton Exchange Membrane (PEM) electrolysers. By mitigating potential supply risks, the study aims to ensure the robust and reliable growth of India’s green hydrogen infrastructure, minimizing disruptions and fostering stability.
IIT Madras emphasized that this study establishes a vital foundation for future scientific inquiry. Subsequent research endeavors will build upon these findings, focusing on areas such as improving life cycle data, conducting more granular assessments of various hydrogen production pathways, and performing thorough analyses of material availability to support scaling hydrogen technologies.
India’s National Climate and Energy Goals
Green hydrogen is a clean fuel, generated by splitting water using electricity from renewable energy sources like solar or wind. It offers a powerful solution for decarbonizing sectors that are traditionally challenging to clean up, including heavy industries (like steel and fertilizer production), long-distance transportation, and energy-intensive building operations.
India has committed to significant national energy transition targets. Beyond its net-zero emissions pledge, the nation aims to source 50 percent of its electricity from non-fossil fuel sources by 2030 . Integrating green hydrogen is key to strengthening India’s energy security, reducing its reliance on imported fossil fuels, and advancing its broader sustainable development agenda by offering a versatile and low-emission energy carrier.
Driving the Green Hydrogen Mission
These national objectives are underpinned by India’s ambitious Green Hydrogen Mission, launched to accelerate the sector’s development. A central goal of this mission is to achieve an annual production capacity of 5 million metric tons of green hydrogen by the year 2030 .
The mission additionally prioritizes bolstering the domestic manufacturing of electrolysers. These specialized devices are fundamental to green hydrogen production, as they efficiently utilize electrical energy to separate water molecules into hydrogen and oxygen. Increasing local production capacity for electrolysers is seen as crucial for achieving self-sufficiency and driving technological innovation within the country.
Expert Perspective on India’s Hydrogen Future
Satyanarayanan Seshadri, who leads The Energy Consortium at IIT Madras, provided expert commentary on the implications of the research. Seshadri stated, “Our research delivers a comprehensive roadmap specifically designed for expanding green hydrogen production in India.”
He further elaborated on the study’s impact: “By understanding the environmental and material implications of different technologies, we can make informed choices that ensure both efficiency and sustainability for the entire sector.” Seshadri underscored the critical link between strategic technology selection and achieving favorable environmental outcomes, highlighting its absolute necessity as India moves forward with scaling up its national hydrogen infrastructure.
