The promise of green iron, steel and ammonia is keeping the green hydrogen dream alive

Hydrogen was as soon as bought as a common local weather repair—a clear, inexperienced wonder fuel for automobiles, properties, energy grids and even international export. However actuality has cooled that buzz.

This week, the South Australian authorities shelved plans for a A$593 million hydrogen power plantin favor of injecting that cash into the $2.4 billion Whyalla steelworks rescue bundle. Premier Peter Malinauskas said there was “no point in producing hydrogen” with out a buyer: the steelworks.

It is the most recent in a collection of setbacks for hydrogen. Final yr, Australian mining and vitality large Fortescue pared again its inexperienced hydrogen initiatives because of increasing costs and changing financial circumstances in the United States.

Then, fuel and oil heavyweight Woodside withdrew plans for two large-scale green hydrogen projects and Origin Energy dropped out of the Hunter Valley Hydrogen Hub.

In the meantime, the Hydrogen Power Provide Chain mission in Victoria, meant to ship hydrogen to Japan, has met with delays and overruns. Earlier this month, the brand new Queensland authorities selected to halt additional funding within the Central Queensland Hydrogen Projectplacing plans to export hydrogen unsure.

These setbacks present hydrogen is not the last word resolution to all our vitality wants, particularly if we wish to export it. However they do not spell doom. As a substitute, they nudge us towards the place hydrogen actually shines: in heavy trade, proper the place it is made.

Heavy trade: The place hydrogen is smart

Heavy industries akin to metal manufacturing and ammonia production are the place hydrogen proves its value. These sectors are vital contributors to local weather change—metal accounts for about 8% of global greenhouse gas emissionsammonia an additional 2%.

Most emissions from steelmaking come from burning coal in blast furnaces to transform ore into iron and carbon dioxide.

In a cleaner different, hydrogen (when produced utilizing renewable vitality) can be utilized to strip oxygen from the ore and make iron, with water as a byproduct. The result’s inexperienced iron, able to be was metal in an electrical arc furnace—with a fraction of the emissions.

Ammonia is used to make fertilizer and industrial chemical substances, and hydrogen is among the foremost components in its manufacturing. Hydrogen bonds with nitrogen from the air to kind ammonia. No hydrogen, no ammonia—it is that easy. Standard ammonia vegetation get hydrogen from methane, producing CO₂ within the course of. Inexperienced ammonia makes use of renewable vitality to provide hydrogen by splitting water through electrolysis.

Our current analysis crunched the numbers on producing these new inexperienced commodities. We discovered making inexperienced iron in Australia with hydrogen and delivery it to Europe for metal manufacturing might be 21% cheaper than exporting uncooked iron ore and hydrogen individually. Plus, it may lower emissions by as much as 95% compared to traditional methods.

There are enormous financial alternatives for Australia too. As a substitute of delivery low-value uncooked supplies, Australia may export ready-to-use inexperienced iron or inexperienced metal, reshaping international provide chains whereas chopping prices and carbon. That is the sort of rethink hydrogen allows.

Trade hubs: A sensible repair

Transporting hydrogen lengthy distances is dear and inefficient. The repair? Trade hubs that produce hydrogen proper the place it is wanted—subsequent to metal mills, ammonia vegetation, desalination vegetation, water therapy vegetation and even aluminum smelters. Placing producers and shoppers collectively slashes transport prices and unlocks efficiencies.

We have constructed instruments to pinpoint locations with the best potential to provide these new inexperienced commodities.

The Hydrogen Economic Fairways Tool maps the place renewable vitality, infrastructure and industrial websites align for cost-effective hydrogen manufacturing.

The Green Steel Economic Fairways Mapper zooms in on prime areas for inexperienced metal, spotlighting locations akin to Eyre Peninsula in SA and the Pilbara in Western Australia, amongst others (see under). These areas have plentiful wind and photo voltaic assets alongside an present industrial base.

Challenges stay

Inexperienced hydrogen guarantees to revolutionize heavy industries, however vital hurdles stand in the best way of widespread home adoption. The largest problem comes from the unpredictable nature of renewable vitality, which makes it arduous to keep up the regular hydrogen provide industries want.

The prices stay steep, too. Splitting water into hydrogen utilizing renewable electrical energy is not low cost, significantly if you want backup storage programs to maintain manufacturing going throughout cloudy or windless durations.

Getting hydrogen the place it must go poses one other main problem. As hydrogen is each cumbersome to move and extremely flammable, it requires particular dealing with and infrastructure, driving up prices, particularly for amenities removed from manufacturing websites.

Many firms additionally hesitate to spend money on hydrogen-compatible gear, as retrofitting present vegetation or constructing new ones requires substantial upfront prices with out assured returns.

Authorities backing: A push in the precise route

Thursday’s announcement of A$2.4 billion investment in the Whyalla steelworks together with plans for a $1 billion green iron investment fund are a daring guess on inexperienced metal. Moreover, the landmark Future Made in Australia legislation introduces a $6.7 billion Hydrogen Manufacturing Tax Incentive, providing $2 per kilogram of renewable hydrogen produced between 2027–28 and 2039–40, alongside a ten% tax credit score for important minerals processing.

In the meantime tax credits for green aluminum and alumina ought to assist one other heavy trade to navigate the vitality transition utilizing clear hydrogen.

These measures intention to unlock tens of billions in personal funding, increase regional economies, and place Australia as a pacesetter in clear vitality manufacturing. This is not nearly one-off initiatives. It is laying the groundwork for hubs that hyperlink renewable vitality and hydrogen manufacturing to industrial demand.

There’s extra within the pipeline. The Hydrogen Headstart program pumps funds into hydrogen innovation, and the Future Made in Australia initiative backs clear trade with billions extra. Add in insurance policies like carbon pricing or low-interest loans, and the economics tilt even additional towards inexperienced metal and ammonia. Authorities shopping for energy—within the type of procurement targets for low-carbon supplies—may seal the deal by guaranteeing demand.

These insurance policies aren’t simply wishful considering—they’re sensible steps which might be already working elsewhere. Sweden’s HYBRIT projectwhich paired inexperienced metal with government-backed demand, has already led to building beginning on new industrial-scale green steel facilities. On the similar time, the European Union’s hydrogen strategy leans on carbon pricing and subsidies to information industries and suppliers by way of the vitality transition, whereas Japan offers incentives for the usage of inexperienced steel of their automotive trade.

Australia has the renewable energy and the commercial base to benefit from these alternatives. With the precise management, we will flip hydrogen’s stumbles into a worldwide triumph for heavy trade.
