AI and Clean Steel: Scaling Near‑Zero Emissions

Steel is a $1.5 trillion market producing about 1.8 billion metric tons a year—and it’s also responsible for roughly 8% of global greenhouse gas emissions. That number lands differently when you work in energy and utilities: steel is everywhere in your world (transmission, substations, pipelines, wind foundations), and steel’s decarbonization is now tightly coupled to how quickly the grid can modernize.

Here’s the practical reality I keep seeing: clean steel isn’t mainly a metallurgy problem anymore. It’s an energy system and operations problem. The technologies exist to slash emissions, but scaling them depends on reliable clean power, affordable hydrogen, and plants that can run efficiently under new constraints. That’s where AI—already proving itself in grid optimization, demand forecasting, and asset management—starts to matter to heavy industry.

This post breaks down what’s changing in steel, why 2026 is a pivotal year, and where AI can help energy and utility leaders (and their partners) turn “pilot projects” into repeatable industrial deployments.

Why steel decarbonization is now an energy-and-utilities issue

Answer first: Steel decarbonization rises or falls on clean electricity, clean hydrogen, and grid reliability—core utility territory.

Traditional steel production is dominated by blast furnace–basic oxygen furnace (BF-BOF) facilities, which account for about 70% of global crude steel output. They run on coal, operate at extreme temperatures, and typically emit around two tons of CO₂ per ton of steel. They also create significant local pollution burdens—an issue that’s increasingly shaping permitting, community acceptance, and corporate risk.

The low-carbon alternatives shift the dependency from coal to electricity and hydrogen. That’s why energy companies keep getting pulled into steel conversations that used to be “someone else’s industrial problem.” If your organization is investing in renewables, transmission upgrades, storage, or hydrogen hubs, steel is becoming a make-or-break anchor customer.

Two additional forces make this urgent:

• Demand is growing. Global steel demand could reach 2.5 billion metric tons by 2050, roughly 39% above today’s levels.
• Supply chains are colliding. Steel wants clean firm power and hydrogen at scale; the grid is already strained in many industrial regions; and clean hydrogen is still expensive.

2026: the year clean steel stops being hypothetical

Answer first: 2026 is a credibility test—commercial volumes of near-zero emissions steel are expected to hit the market, and buyers will start treating emissions as a product spec.

A major signal is expected out of Northern Sweden, where Stegra plans to produce and sell the first commercial volumes of near-zero emissions steel. The company has raised $6.5 billion in combined private and public capital and is building toward 5 million metric tons of annual production. That’s a real industrial footprint.

But it’s also a cautionary story. Even with strong momentum, large projects can stall on the unglamorous parts: contracting, offtake certainty, and the cost and availability of hydrogen. Stegra reportedly still has a meaningful portion of future production uncommitted, which highlights a bigger point:

The hard part of clean steel isn’t proving the chemistry—it’s proving the commercial model.

For utilities and energy developers, this is familiar. It echoes renewables in the 2010s: the technology curve improved fast, but bankability depended on contracts, interconnection, and operational confidence.

The three pathways: make less, make better, make new

Answer first: Net-zero steel won’t come from a single “winner”—it’ll come from combining circularity, incremental retrofits, and new production routes.

A useful way to understand the innovation landscape is by grouping it into three strategies.

Make less: circularity and design efficiency

Direct answer: Recycling and smarter design reduce virgin steel demand, which is the cheapest emissions cut you’ll ever buy.

Scrap-based steelmaking (often via electric arc furnaces, EAFs) can materially reduce emissions—especially when powered by low-carbon electricity. The catch is regional: scrap supply depends on how much steel is reaching end-of-life, and many fast-growing economies are still “building their future scrap pile.”

Where AI fits immediately:

• AI-enabled scrap sorting (computer vision + optical sensors) improves yield and quality, reducing the need for virgin inputs.
• Contamination detection (copper/tin issues) can be automated, improving the ability to make higher-grade products from scrap.
• Digital product passports can improve traceability and future recovery—especially relevant as policy and procurement tighten.

From a utility perspective, higher scrap/EAF penetration changes load profiles. EAFs are large, fast-ramping loads; if coordinated well, they can act like flexible demand. If coordinated poorly, they stress the grid.

Make better: decarbonize what exists without coal lock-in

Direct answer: The best BF-BOF improvements are low-capex, low-downtime, and don’t extend coal’s life.

There’s no realistic path to net-zero blast furnace steelmaking at scale today. That doesn’t mean you ignore BF-BOF; it means you prioritize retrofits that cut emissions now without creating a “coal plant that lasts another 20 years.”

Promising “make better” moves include:

• Electrifying heat where feasible
• Fuel switching (including carefully sourced bio-materials)
• Process controls and efficiency upgrades

This is a sweet spot for industrial AI:

• Advanced process control to reduce fuel use and stabilize operations
• Predictive maintenance for high-wear equipment (fans, refractory, conveyors)
• Digital twins to test retrofit scenarios before downtime-heavy changes

Utilities can add value by offering industrial demand response products and clean firm power packages that match plant reliability needs.

Make new: novel production routes built for renewables

Direct answer: “Make new” technologies aim to avoid coal entirely—and some are designed to run at lower temperatures that pair better with variable renewables.

Two big incumbent-friendly routes already exist:

• DRI + EAF using natural gas can cut emissions by about 40% compared to BF-BOF (more if electricity is clean).
• Hydrogen DRI (H2‑DRI) + EAF is the only commercially plausible net-zero primary route today—if you have enough low-cost clean hydrogen.

But the most interesting frontier is a set of novel approaches trying to solve the scaling bottlenecks: hydrogen cost, ore quality constraints, and renewable variability.

Key themes emerging from innovators:

• Low-temperature reduction (<350°C): easier to align production with renewable availability.
• Raw material flexibility: compatibility with lower-grade ores (critical where DR-grade pellets are limited).
• Modularity: smaller units (tens of thousands of tons/year) that can be sited near renewables, ports, mines, or demand centers.

For energy and utilities, modularity is strategically important: it opens a path for industrial growth in regions where grid build-out is still underway, because production can co-locate with distributed renewables and storage.

Where AI directly accelerates clean steel scaling

Answer first: AI helps clean steel in four concrete ways: energy optimization, hydrogen optimization, quality control, and finance-grade performance assurance.

If you’re deciding where to apply AI (or evaluating vendors), don’t start with generic “Industry 4.0” aspirations. Start with these operational choke points.

1) Energy optimization for EAFs and electrified heat

EAFs are only as clean as the grid—and only as profitable as their power procurement strategy.

AI can:

• Forecast short-term power prices and carbon intensity for load shifting
• Optimize charge timing and tap-to-tap cycles against grid constraints
• Coordinate with on-site storage to smooth peaks and avoid demand charges

Utilities benefit too: a coordinated EAF can become a grid asset rather than a grid problem.

2) Hydrogen supply, scheduling, and consumption control

H2‑DRI needs large, steady hydrogen volumes. Clean hydrogen remains expensive, so every percent reduction in hydrogen use matters.

AI can:

• Optimize electrolyzer dispatch based on renewable output and price
• Predict hydrogen storage needs and manage buffering
• Reduce hydrogen consumption via process analytics and waste-gas recycling optimization

This is a tight intersection of renewable energy integration, industrial operations, and energy trading.

3) Ore and pellet quality analytics

DRI pathways need higher-quality feedstocks (like DR pellets), but many regions struggle with ore beneficiation and pelletizing.

AI can improve:

• Orebody characterization and blending strategies
• Pellet plant energy use and throughput
• Quality stability that reduces downstream rework and emissions

For utilities, better upstream stability means more predictable industrial loads and fewer upset-driven spikes.

4) “Bankability”: proving performance to unlock capital

Steel projects are capital intensive and risk-sensitive. Financiers want proof that a plant can hit production, cost, and emissions targets.

AI-enabled monitoring and verification can support:

• Transparent emissions accounting at batch or heat level
• Predictive reliability metrics for insurers and lenders
• Contract confidence for buyer offtake agreements

A blunt take: If you can’t measure it in a way that convinces a lender, it won’t scale.

What energy and utility leaders should do next

Answer first: Treat clean steel as a strategic demand segment and build offerings around clean firm power, flexibility, and hydrogen integration.

If you’re in an energy company or utility, there are practical steps you can take in 2026 planning cycles.

Build a “clean industrial load” playbook

Focus on repeatable packages:

• Interconnection and timeline certainty
• Clean firm power combinations (renewables + storage + firming)
• Demand response / flexibility programs designed for EAF and electrolyzer behavior

Offer data-grade reliability, not just megawatts

Heavy industry pays for confidence. AI-driven grid analytics can help you provide:

• Congestion and curtailment risk modeling
• Power quality guarantees where feasible
• Predictive maintenance and outage risk insights

Co-develop pilots that turn into templates

The most scalable partnerships are the ones that standardize:

• Metering and emissions tracking
• Cybersecurity and OT/IT integration
• Operating procedures for variable renewables + industrial processes

If the pilot can’t be copied five times, it’s not a real strategy.

The steel transition is also a grid transition

Clean steel is a climate priority because it tackles one of the largest industrial emissions sources—about 8% of global emissions. It’s also an energy systems priority because it creates massive new demand for electricity and hydrogen, exactly when grids are trying to absorb more renewables and retire fossil generation.

For the AI in Energy & Utilities series, this is the connection that matters: the same AI capabilities used for grid optimization, demand forecasting, and predictive maintenance can also help heavy industry run cleaner, cheaper, and more reliably. And when steel plants become flexible, data-driven customers, utilities get a stronger, more manageable path to electrification at scale.

The next 12–24 months will sort serious clean steel deployments from good-looking demonstrations. If you’re building the grid, building hydrogen supply, or selling energy to industry, now’s the moment to decide where you’ll participate—because steel’s buying decisions are starting to look a lot like energy transition decisions.
