Hindustan Zinc Signs a Green Hydrogen MoU to Clean Up Its Mining
Hindustan Zinc is India’s biggest maker of zinc (a common metal). The company wants to make its mining cleaner. So on 22 June 2026, it signed a green hydrogen MoU. An MoU (a Memorandum of Understanding) is a written promise between companies to work together and study an idea. It is not a final deal, so no money has been spent yet. Think of it as two sides shaking hands and saying, “Let’s see if this can work.”
Green hydrogen is a clean fuel. It is made by splitting water using electricity from clean sources like the sun or wind. When you burn it, it gives off water vapour, not smoke. The company plans to use it to cut the pollution from its heavy mining work. This deal is just an early step in that plan.
Who signed the deal and what it covers
Hindustan Zinc signed the MoU with two partners. They are Advantek Associates LLP and Aero Eagle Automobiles Private Limited. Together, the three will check if green hydrogen and other clean energy can work in mining.
The study will look at the whole way hydrogen is used. This means making the hydrogen, storing it safely, and building pumps to fill up machines. The partners will also test two kinds of engines.
The first is a Hydrogen Internal Combustion Engine, or H2-ICE. This is a normal engine that burns hydrogen instead of diesel. The second is a fuel cell. A fuel cell is a device that turns hydrogen into electricity, with no burning at all.
If the tests work well, these clean engines could run many things. They could power mining trucks, heavy machines, vehicles above and below the ground, and generators. The plan is to go step by step, not all at once.
Why underground mining is a big deal here
Most mining machines run on diesel. Diesel is cheap and strong, but it makes a lot of fumes. That is a real problem underground, where there is not much fresh air. Mines must spend a lot of money on fans and tunnels just to clear out the smoke.
Green hydrogen could change this. A fuel cell makes only water vapour, so the air stays cleaner. Hindustan Zinc says this deal could make it one of the first firms in India to use hydrogen fuel deep inside mines. That is a hard place to test new technology. So this is a big goal.
The bigger climate goal: net zero by 2050
This deal is part of a larger plan called decarbonisation. Decarbonisation just means cutting the carbon dioxide a company puts into the air. Carbon dioxide is the main gas that warms the planet. Burning diesel makes a lot of it.
A big part of a miner’s pollution comes from its own machines and trucks. These are called Scope 1 emissions. Scope 1 emissions are the pollution a company makes directly from its own machines and vehicles. Using green hydrogen instead of diesel would cut these emissions a lot.
Hindustan Zinc wants to reach “net zero” by 2050 or sooner. Net zero means a company removes or avoids as much greenhouse gas as it still gives out. So its overall effect on the climate is close to nothing. Its goals have been checked by the Science Based Targets initiative (SBTi). The SBTi is a group that makes sure climate promises are real and not just for show. The company is also a member of the International Council on Mining and Metals (ICMM). The ICMM is a group that pushes miners to act responsibly.
What the CEO said
Arun Misra is the CEO (the top boss) of Hindustan Zinc. He explained why hydrogen matters. He said, “Hydrogen has the potential to support cleaner mobility, reduce emissions from heavy-duty equipment, and create new pathways for decarbonising hard-to-abate industrial operations.”
“Hard-to-abate” is just a phrase for industries that are very hard to clean up, like mining and steel. They use so much fuel and heat that easy fixes are not enough. That is why companies are testing new fuels like hydrogen.

|---|---|
| Date of MoU | 22 June 2026 |
| Company | Hindustan Zinc Limited |
| Partners | Advantek Associates LLP and Aero Eagle Automobiles Pvt Ltd |
| Goal | Study green hydrogen and clean fuels for mining |
| Engines tested | H2-ICE (burns hydrogen) and fuel cells (no burning) |
| Net zero target | 2050 or sooner |
| Share price (23 June) | Rs 552.50, down 3.61% (a fall of Rs 20.70) |
How the market reacted
The stock did not jump on this news. A share is a small piece of a company that people can buy. On 23 June 2026, Hindustan Zinc shares were trading at about Rs 552.50. That was down 3.61% from the day before. It was a drop of about Rs 20.70 per share.
Why did the price fall? An MoU is only a study, not a money-making project yet. Investors are people who put money into a company to earn more later. They often care more about profits in the next few months. A clean-energy plan may take years to pay off. So the reaction was calm, even though the long-term idea is a serious one.
FAQ
What is green hydrogen?
It is a clean fuel. It is made by splitting water with electricity from clean sources like the sun and wind. Using it gives off water vapour instead of harmful smoke.
Is this a final deal or just a plan?
It is just a plan for now. An MoU is a promise to study an idea together. The companies will first run feasibility studies (tests to see if the idea can really work) before spending big money or building anything.
What are Scope 1 emissions?
They are the greenhouse gases a company makes directly from its own machines, trucks, and equipment. Using hydrogen instead of diesel would cut these gases.
When does Hindustan Zinc want to reach net zero?
By 2050 or sooner. Net zero means balancing out almost all the greenhouse gas it still gives out. So its effect on the climate is close to zero.
Why it matters (especially for India and founders)
India wants to be a world leader in green hydrogen. It even has a national plan to help this happen. When a big company like Hindustan Zinc tests hydrogen in a hard setting like mining, it helps the whole market. It builds skills, suppliers, and trust in the new fuel.
For founders and students, this is a signal worth watching. Big firms are now looking for partners who can supply hydrogen tools, storage, pumps, and engines. That opens doors for small companies and startups in clean energy. The two partners here, Advantek and Aero Eagle, show that small players can win a seat at the table with a giant.
It is also a lesson in patience. Real change in heavy industry starts with quiet studies, not flashy launches. The investors who sold the stock want quick wins. But climate fixes take years. People who plan for the long game often find the biggest chances.
The takeaway
Hindustan Zinc’s green hydrogen MoU is a small but smart first step. It will not clean up its mines overnight, and the share price even slipped on the news. But the plan points clearly toward cleaner, safer mining and the company’s net-zero goal for 2050. If the tests go well, India could see hydrogen-powered machines working deep underground in the years ahead.
