Green Hydrogen: Heavy Industry Frontier

Batteries can't decarbonise steel, mining, or marine. Here's why green hydrogen is the only answer for India's hardest industrial sectors.

India's industrial engine is one of the most carbon-intensive on the planet. Steel furnaces, cement kilns, chemical plants, mining operations, and marine fleets collectively account for a significant share of the country's greenhouse gas emissions and they share one critical problem: batteries cannot save them.

This is the domain where green hydrogen stops being a talking point and starts being the only viable answer.

What Is Green Hydrogen and Why Does It Matter for Industry?

Green hydrogen is produced through electrolysis; passing renewable electricity through water to split it into hydrogen and oxygen. The result is a zero-carbon fuel with no combustion byproduct other than water vapour.

Unlike grey hydrogen (produced from natural gas) or blue hydrogen (natural gas with carbon capture), green hydrogen carries no embedded emissions. When produced using solar or wind power, its lifecycle carbon footprint is effectively zero.

For India, this matters enormously. The India green hydrogen market was valued at USD 1.95 billion in 2025 and is projected to reach USD 35.26 billion by 2034, growing at a CAGR of 37.92%. The demand is not speculative, it is being driven by real industrial need, regulatory pressure, and a government mission that has put serious capital behind it.

India's National Green Hydrogen Mission, launched in January 2023 with an outlay of INR 19,744 crore (USD 2.4 billion), sets a bold target of 5 million metric tonnes of green hydrogen production annually by 2030.

2026 is the year this moves from policy to deployment. India's green hydrogen capacity stood at 8,000 tonnes per annum as of February 2026, with the pipeline growing to nearly 40,000 tonnes per annum as significant commercial signals emerge.

Why Batteries Cannot Do This Job

Battery technology has transformed personal transport and light commercial vehicles. But heavy industry operates on a fundamentally different energy scale and batteries hit a wall.

Consider the physics: a lithium-ion battery pack capable of powering a long-haul truck for 500 kilometres would weigh approximately 4–5 tonnes, consuming payload capacity and adding structural stress. For a marine vessel, the numbers become even more prohibitive. For a steel blast furnace running continuously at 1,600°C, the concept of battery power is simply irrelevant.

Green hydrogen solves the energy density problem directly. It carries roughly three times the energy per kilogram compared to diesel, and it can be stored, transported, and consumed at industrial scale without the weight or degradation penalties of battery chemistry.

The sectors where this matters most are precisely those that define India's industrial backbone.

Steel: The Biggest Prize

India is the world's second-largest steel producer, with crude steel output reaching 168.4 million tonnes in FY 2025-26. Steel production registered a robust 9.1% growth in FY 2025-26 compared to the previous year. But the majority of this production runs on coal, specifically the blast furnace route, which is among the most carbon-intensive industrial processes in existence.

The green hydrogen pathway for steel is well established: the DRI-EAF route (Direct Reduced Iron using hydrogen, fed into an Electric Arc Furnace) replaces coal as the reductant, eliminating the CO2 that conventional steelmaking produces as an unavoidable byproduct. Green hydrogen in steelmaking can significantly reduce CO2 emissions, particularly through the hydrogen-based DRI-EAF route.

Under the National Green Hydrogen Mission, India's Ministry of Steel has already awarded 4 pilot projects for use of hydrogen in the steel sector.

The economics are moving fast. At present, green hydrogen production costs range from USD 3–6 per kg, but analysts predict costs will drop to USD 1–2 per kg by 2030 as scale and policy incentives take effect. When that threshold is crossed, carbon-intensive steel production will face mounting penalties — especially from the EU's Carbon Border Adjustment Mechanism (CBAM), which is already reshaping the economics of Indian exports to Europe.

For Indian steel producers with European customers, decarbonisation is no longer a CSR aspiration. It is a trade necessity.

Marine and Coastal Shipping: The Silent Polluter

India has over 7,500 kilometres of coastline and one of the busiest coastal shipping corridors in Asia. Marine diesel is among the dirtiest fuels in the energy system high in sulphur, nitrogen oxides, and CO2.

Hydrogen fuel cells offer a genuinely clean alternative for coastal vessels, ferries, and offshore support ships. Unlike massive battery packs, hydrogen fuel cells provide the energy density needed for extended maritime range without compromising cargo or passenger capacity.

The economics of hydrogen for marine applications are particularly compelling in the context of India's coastal trade routes, where refuelling infrastructure can be concentrated at major ports: Chennai, Mumbai, Kandla, Kochi, rather than distributed across thousands of kilometres of road network.

Green hydrogen maritime corridors are not a distant concept. They are being planned and piloted across South and Southeast Asia, and India's port infrastructure positions it to be a regional hub.

Mining and Heavy Transport: The Last-Mile Problem

India's mining sector like coal, iron ore, bauxite, limestone operates fleets of haul trucks, excavators, and ore processors in remote locations far from grid infrastructure. These sites run on diesel by default, not by preference. The logistics cost and carbon footprint of fuel supply chains to remote mines is enormous.

Hydrogen offers a different model: on-site generation using solar-powered electrolysers, feeding hydrogen directly into fuel cell vehicles and stationary power systems. No fuel logistics. No grid dependency. Zero emissions at the point of use.

This is precisely the deployment model that Cosmos Power Technologies is built around — bringing hydrogen generation infrastructure to the site rather than transporting fuel to it.

The "Last-Mile" Cost Problem and How We Solve It

The historic barrier to industrial hydrogen adoption has not been the technology. It has been the economics of getting hydrogen from where it is produced to where it is needed.

Centralised hydrogen production requires pipelines, compression, liquefaction, or tube trailer logistics each adding cost and complexity. For an industrial site in Jharkhand or Rajasthan, the delivered cost of hydrogen from a centralised plant is prohibitive.

Cosmos Power's approach addresses this directly through the VapourGen™ PEM electrolyser system: A modular, on-site hydrogen generation platform that uses local renewable electricity to produce hydrogen at the point of consumption. Combined with our Zero CAPEX deployment model, industrial operators can access hydrogen infrastructure as a service, paying only for the energy consumed rather than financing capital equipment.

This eliminates the last-mile cost barrier that has held back industrial hydrogen adoption in India for the past decade.

The Regulatory Tailwind

Two international regulatory mechanisms are accelerating the timeline for Indian industrial decarbonisation:

EU CBAM (Carbon Border Adjustment Mechanism): From 2026, Indian exporters of steel, cement, aluminium, and chemicals to Europe face carbon pricing on their emissions. Companies that cannot demonstrate low-carbon production will pay a premium or lose market access.

EU RFNBO (Renewable Fuels of Non-Biological Origin): Sets strict certification standards for hydrogen used in industrial processes, requiring verifiable renewable electricity inputs and traceability.

These international mandates are acting as regulatory catalysts, making decarbonisation essential for Indian exporters.

For Indian industry, the question is no longer whether to decarbonise — it is how fast, and with which partners.

What This Means for Indian Industry in 2026

The window for early adoption advantage is open right now. Companies that begin their hydrogen transition in 2026 will:

Build operational expertise ahead of mandated compliance deadlines
Qualify for National Green Hydrogen Mission incentives while funding is available
Establish verifiable low-carbon credentials for export markets
Lock in long-term energy costs before hydrogen infrastructure becomes commoditised

The sectors best positioned to move first are those with the highest energy intensity, the greatest diesel dependency, and the clearest export exposure to carbon-pricing mechanisms: steel, mining, marine, and defence.

Conclusion

Green hydrogen is not a technology of the future. It is a technology of this industrial cycle and the industries that treat it as such will emerge from India's energy transition as globally competitive, low-carbon producers.

For hard-to-abate sectors where batteries are irrelevant and fossil fuels are becoming economically and regulatorily untenable, hydrogen is not one option among many. It is the pathway.

Cosmos Power Technologies exists to make that pathway accessible — at zero CAPEX, at industrial scale, and at the point where the energy is actually needed.
