Synopsis: Hindustan Zinc Limited has signed a Memorandum of Understanding with Advantek Associates LLP and Aero Eagle Automobiles Private Limited to explore green hydrogen and alternative clean fuel solutions across its mining operations, marking a first-of-its-kind initiative in India’s mining sector.
Following the announcement, shares of Hindustan Zinc Limited adjusted by 3.30%, trading at ₹554.30 as of midday on June 23, 2026. The stock touched an intraday high of ₹564.05 and a low of ₹553.05, bringing the company’s total market capitalization to approximately ₹2,34,209 crore. While the intraday price reflected immediate market fluctuations, Hindustan Zinc maintains a strong long-term trajectory, securing a solid 25.82% absolute return over the past year.
Hindustan Zinc Limited has positioned itself at the frontier of sustainable mining in India, announcing the signing of a three-way MoU with Advantek Associates LLP and Aero Eagle Automobiles Private Limited to evaluate and pilot green hydrogen fuel solutions across its operations. The disclosure, filed with BSE and NSE on June 22, 2026, under Regulation 30 of the SEBI Listing Regulations, signals that the world’s largest integrated zinc producer is preparing to take on one of the most stubborn decarbonisation challenges in heavy industry emissions from underground mining and high-capacity earth-moving equipment.
The significance of this collaboration extends well beyond a routine ESG initiative. Underground mining environments represent one of the hardest-to-decarbonise domains in all of industrial operations. Diesel-powered equipment from underground loaders and haul trucks to surface vehicles and generators contributes substantially to mining companies’ Scope 1 emissions and is notoriously resistant to battery-electric alternatives due to the weight, ventilation, and operational intensity involved.
Hydrogen fuel technologies, including Hydrogen Internal Combustion Engines and fuel cell systems, are emerging as the most technically viable pathway for this specific use case, and Hindustan Zinc is now the first Indian mining company to formally evaluate their deployment in underground environments.
Unlocking Tripartite Synergies
The true engine behind this project is the precise operational synergy generated by combining the unique specializations of these three distinct entities. Hindustan Zinc provides the massive real-world testing ground, heavy mining asset infrastructure, and the necessary financial backing.
Advantek Associates acts as the specialized technical and strategic advisor, engineering the background logistics for green hydrogen production, safe storage, and dispensing networks. Meanwhile, Aero Eagle Automobiles steps in with proprietary automotive expertise, designing and deploying the custom modifications required to integrate hydrogen fuel cells and H2-ICE powertrains directly into existing heavy machinery. By uniting infrastructure, logistics engineering, and automotive integration under a unified blueprint, the partnership bypasses the isolated operational barriers that often stall large-scale green fuel initiatives.
This move fits squarely within Hindustan Zinc’s broader ESG architecture. The company has committed to achieving Net Zero by 2050 or sooner, holds Science Based Targets initiative-validated goals, and is a member of the International Council on Mining and Metals.
Renewable energy already accounts for nearly 18% of its power mix, and it operates EcoZen Asia’s first low-carbon green zinc brand produced using renewable energy. The hydrogen initiative, if successfully scaled, could materially reduce the company’s hard-to-abate Scope 1 emissions and further cement its standing as the world’s most sustainable metals and mining company, a distinction it has held for three consecutive years in the S&P Global Corporate Sustainability Assessment.
Hindustan Zinc Limited, a Vedanta Group company, is the world’s largest integrated zinc-lead producer and among the top ten silver producers globally. Headquartered in Udaipur, Rajasthan, the company supplies zinc, lead, silver, and cadmium to over 40 countries and commands approximately 74% of India’s primary zinc market. Recognised for its industry-leading sustainability practices, Hindustan Zinc is certified 3.32 times Water Positive and is committed to transforming its operations into a future-ready, low-carbon metals business through technology, renewable energy adoption, and responsible resource management.
