Green hydrogen procurement contracts for heavy industry

Who offers green hydrogen procurement contracts for heavy industry?

As of October 2026, the strongest starting points for industrial buyers are RWE, EWE, Uniper, Air Products, Air Liquide, Linde, and Iberdrola, alongside procurement intermediaries such as H2Global. They differ in whether they can contract directly for renewable hydrogen, supply hydrogen derivatives such as green ammonia, or help buyers aggregate demand.

For steelmaking, refining, chemicals, fertilizers, and other energy-intensive industries, I would prioritize suppliers with demonstrated long-term offtake agreements over developers that have only announced projects.

Leading suppliers and procurement routes

• 

1. RWE — industrial-scale direct supply

(Proven long-term contract)

Best for: Refineries, chemicals, industrial clusters

RWE agreed to supply TotalEnergies' Leuna refinery with approximately 30,000 tonnes of green hydrogen annually from 2030 through 2044, linked to its electrolyzer project in Lingen, Germany. This is a strong reference model for a large industrial buyer seeking a long-term supply agreement.www.rwe.com+1

• 

7. Iberdrola — renewable power and hydrogen project development

Best for: Steel, fertilizers, refining, European industrial hubs

Iberdrola develops renewable-energy and green-hydrogen projects and is relevant where an industrial buyer wants to link renewable electricity, electrolyzer production, and long-term hydrogen offtake. Confirm which projects are operational or contracted and which remain under development.

Iberdrola website

8. Procurement intermediary: H2Global / Hintco

• 

(Alternative contracting route)

H2Global is particularly interesting for buyers who want to procure renewable hydrogen or derivatives through competitive auctions rather than negotiate the entire supply chain independently.

Hintco, its trading intermediary, contracts with producers through longer-term purchase agreements and resells products through buyer auctions. Eligible products include renewable hydrogen, ammonia, and methanol. Buyer participation depends on the relevant tender and its eligibility rules.www.h2-global.org+1

• Current and upcoming tenders
• Buyer-side auction information

Which providers should you approach first?

For US buyers, the Department of Energy's Regional Clean Hydrogen Hubs program is another useful starting point for identifying production, transportation, and industrial demand networks. However, a hub award or development project is not itself a guarantee that a supplier has available green hydrogen under a commercial contract.www.energy.gov

What to request in a procurement RFP

When contacting these providers, request proposals covering:

• Volume: annual tonnes and minimum guaranteed hourly or daily delivery.
• Timing: immediate supply versus future delivery after a new electrolyzer becomes operational.
• Price: fixed price, indexed price, renewable-power pass-through, and any green premium.
• Certification: renewable electricity provenance and compliance with the applicable green-hydrogen standard.
• Delivery: pipeline, on-site production, compressed gas, liquid hydrogen, or ammonia converted back to hydrogen.
• Contract terms: take-or-pay obligations, price adjustment, minimum offtake, supply shortfalls, and termination rights.

One important distinction: a contract for low-carbon hydrogen is not necessarily a contract for green hydrogen. Specify the certification and emissions methodology you require.

Procurement and long-term offtake contracts for green hydrogen are primarily offered by major global industrial gas conglomerates, energy supermajors, and specialized clean-tech project developers . Because green hydrogen production requires massive upfront capital expenditure and dedicated renewable power, these contracts are usually structured as long-duration offtake agreements or joint-venture supply frameworks tailored to hard-to-abate heavy industries (such as steel, chemicals, refining, and heavy transport).gh2.org

The primary entities offering green hydrogen procurement contracts include:

• Air Products and Chemicals, Inc. : The world's largest hydrogen supplier, actively developing and managing multi-billion-dollar mega-scale green hydrogen and green ammonia production facilities globally (such as the massive NEOM project and U.S. projects backed by dedicated wind and solar) offering long-term supply contracts.
• Air Liquide : A global industrial gas leader offering low-carbon and renewable hydrogen procurement options, backed by industrial-scale electrolyzers (such as projects in Europe) and secured via green power purchase agreements (PPAs).
• Linde plc : The world's largest industrial gas company, which builds, owns, and operates green hydrogen production facilities and provides customized merchant and pipeline supply contracts for industrial and manufacturing clients.
• Energy Supermajors and Utilities (e.g., Shell, BP, and Engie) : Broad energy companies leveraging their massive renewable portfolios to offer customized corporate green hydrogen and green ammonia procurement terms for heavy manufacturing and chemical feedstock users.
• Specialized Clean Hydrogen & Electrolyzer Developers (e.g., Plug Power) : Companies that deploy localized or multi-gigawatt electrolyzer ecosystems, offering direct equipment-to-supply framework agreements for industrial users looking to integrate green hydrogen on-site or regionally.
• Collaborative Market Makers (e.g., Green Hydrogen Coalition / HyBuild) : Organizations working to aggregate multi-sector heavy industry demand (such as steelmakers and logistics firms) to streamline bankable purchase agreement frameworks and standardize procurement.ghcoalition.org

If you are looking to source green hydrogen or draft an offtake agreement, let me know:

• What specific heavy industry sector (e.g., steel, ammonia/fertilizers, refining) you are working with
• The volume and geographic region required

I can provide more targeted details on contract structures or active regional suppliers.

Green hydrogen suppliers for heavy industry

For heavy industrial applications, you’ll want suppliers that can do more than sell hydrogen by the kilogram. The strongest candidates offer long-term green hydrogen offtake agreements, industrial-scale supply, delivery infrastructure, and credible renewable-energy sourcing.

For steelmaking, refining, ammonia and fertilizer production, chemicals, cement, and other energy-intensive operations, I’d focus on three procurement models:

• Direct supply contracts: A producer supplies hydrogen by pipeline, trailer, or on-site production.
• Long-term offtake agreements: Your facility commits to buying a defined volume over multiple years, often with negotiated pricing and volume flexibility.
• On-site or co-located production: A supplier develops or operates an electrolyzer at or near your industrial site.

The best route depends heavily on your plant's location, hydrogen demand, and whether you need gaseous hydrogen, liquid hydrogen, or hydrogen delivered through a pipeline.

2. Compare suppliers against your procurement needs

These are not equivalent offers: some are established supply services, while others depend on planned production and future delivery dates. The published contracts establish commercial precedents, not that these suppliers currently have uncommitted capacity available for your facility.

3. What to require in your RFP

When contacting these suppliers, request a binding or indicative commercial proposal covering:

• Annual volume: tonnes per year, minimum and maximum quantities, ramp-up schedule, and peak hourly demand.
• Contract term: for example, 5, 10, or 15 years, with commissioning and start-of-delivery milestones.
• Delivered price: price per kilogram at your facility, including compression, transport, storage, and any renewable-energy premium.
• Green certification: production pathway, lifecycle carbon intensity, renewable electricity sourcing, and independent verification.
• Reliability: guaranteed availability, backup supply, outage provisions, and penalties for missed deliveries.
• Commercial flexibility: take-or-pay obligations, volume tolerance, price indexation, termination rights, and force majeure provisions.

For a U.S. facility, align emissions reporting with your intended regulatory and incentive requirements; DOE's hydrogen guidance and the applicable IRS rules are useful starting points.www.hydrogen.energy.gov+2

Key Contract Considerations for Heavy Industry

When entering negotiations with these suppliers, industrial offtakers typically focus on:

1. Tenure and Volume: Securing 10-to-15-year legally binding HPAs (Hydrogen Purchase Agreements) to lock in baseload volume delivery schedules and support project bankability.
2. Certifications & Additionality: Ensuring strict guarantees regarding renewable energy matching and carbon-intensity thresholds (complying with regional standards like RED II in Europe or IRA guidelines in the U.S.).
3. Price Structures: Managing the "green premium" gap through fixed-price mechanisms, indexing to local renewable power PPAs (Power Purchase Agreements), or utilizing structured public intermediary frameworks like Europe's H2Global double-auction schemes.irena.org+1
