The Most Promising Applications of Hydrogen in Industry
Published on February 25, 2025
Introduction to Hydrogen’s Industrial Potential
Hydrogen is increasingly recognized as a cornerstone of the global transition to sustainable energy. As industries face mounting pressure to reduce carbon emissions, hydrogen offers a versatile and low-carbon alternative to traditional fossil fuels. Its applications span multiple sectors, but three stand out for their immediate potential and scalability: refining, ammonia production, and steel manufacturing. This article delves into these applications, highlighting their technical feasibility, environmental benefits, and real-world examples, tailored for chemical industry consultants seeking actionable insights.
Hydrogen in Refining: Decarbonizing Fuel Production
The refining industry, responsible for producing gasoline, diesel, and other petroleum products, is one of the largest industrial consumers of hydrogen. Traditionally, this hydrogen is derived from natural gas via steam methane reforming (SMR), a process that emits significant CO2. However, the shift toward green hydrogen—produced through electrolysis powered by renewable energy—promises to decarbonize refining operations.
Hydrogen plays a critical role in hydrocracking and desulfurization processes. Hydrocracking breaks down heavy hydrocarbons into lighter, more valuable fuels, while desulfurization removes sulfur compounds to meet stringent environmental regulations. By replacing grey hydrogen (from SMR) with green hydrogen, refineries can slash their carbon footprint without altering existing infrastructure significantly.
Example: BP’s refinery in Lingen, Germany, is a pioneering case. In collaboration with Ørsted, BP plans to integrate a 50 MW electrolyzer to produce green hydrogen, aiming to reduce emissions from its refining processes by 2025. This project exemplifies how hydrogen can align refining with net-zero goals, offering a scalable model for the industry.
For consultants, the key takeaway is the dual benefit of green hydrogen: it meets regulatory demands while leveraging existing refining technologies, minimizing capital expenditure.
Hydrogen in Ammonia Production: Greening Fertilizer Manufacturing
Ammonia production, primarily for fertilizers, is another industrial giant poised for a hydrogen-driven transformation. The Haber-Bosch process, which synthesizes ammonia from nitrogen and hydrogen, consumes approximately 1-2% of global energy and relies heavily on hydrogen sourced from natural gas. This makes ammonia production a major emitter of greenhouse gases, contributing over 400 million tons of CO2 annually.
Green hydrogen offers a sustainable alternative. By pairing renewable energy with electrolyzers, manufacturers can produce carbon-neutral ammonia, often referred to as “green ammonia.” This not only reduces emissions but also positions ammonia as a potential hydrogen carrier and fuel, expanding its industrial utility.
Example: Yara International, a leading fertilizer producer, is advancing green ammonia production at its facility in Porsgrunn, Norway. The company has deployed a 24 MW electrolyzer, powered by hydropower, to supply hydrogen for ammonia synthesis. This initiative aims to cut emissions by 800,000 tons of CO2 per year, demonstrating the scalability of hydrogen in this sector.
For chemical industry consultants, green ammonia represents a high-impact opportunity. It aligns with global food security needs while addressing decarbonization mandates, making it a priority for investment and innovation.
Hydrogen in Steel Manufacturing: Revolutionizing a Carbon-Intensive Industry
Steel manufacturing is among the most carbon-intensive industries, accounting for 7-9% of global CO2 emissions. Traditional blast furnace methods rely on coke (derived from coal) to reduce iron ore into molten iron, releasing vast amounts of CO2. Hydrogen offers a groundbreaking alternative through direct reduction processes, where it serves as a reducing agent instead of carbon.
In hydrogen-based direct reduction (H-DR), iron ore is reduced to sponge iron using hydrogen, ideally green hydrogen, producing water vapor rather than CO2. This process, when paired with electric arc furnaces (EAF), can produce steel with near-zero emissions. While scaling H-DR requires significant investment in hydrogen supply chains, its potential to decarbonize steel is unparalleled.
Example: Sweden’s HYBRIT project, a collaboration between SSAB, LKAB, and Vattenfall, is a flagship initiative. In 2021, HYBRIT produced the world’s first fossil-free steel using hydrogen from renewable sources. By 2026, the project aims to commercialize this technology, targeting a 25% reduction in Sweden’s total CO2 emissions. This milestone underscores hydrogen’s transformative role in steelmaking.
Consultants should note the long-term implications: as steel demand grows, hydrogen-based production could become a competitive differentiator, especially in markets with stringent carbon pricing.
Challenges and Opportunities
While hydrogen’s promise is clear, challenges remain. The high cost of green hydrogen production, driven by electrolyzer expenses and renewable energy availability, is a primary hurdle. Infrastructure for hydrogen storage and distribution also lags behind demand. However, declining renewable energy costs and government incentives—such as the EU’s Hydrogen Strategy and the U.S. Inflation Reduction Act—are accelerating adoption.
For chemical industry consultants, these challenges translate into opportunities. Advising clients on hydrogen supply chains, integrating electrolysis into existing plants, and navigating subsidies can position firms as leaders in this transition.
Conclusion
Hydrogen is poised to redefine industrial processes, with refining, ammonia production, and steel manufacturing at the forefront. By leveraging green hydrogen, these sectors can achieve significant decarbonization while maintaining productivity. Real-world examples like BP’s Lingen refinery, Yara’s Porsgrunn plant, and the HYBRIT project illustrate the feasibility and scalability of these applications. For chemical industry consultants, hydrogen represents both a technical and strategic frontier—one that demands expertise, foresight, and a commitment to sustainability.
As the world races toward net-zero emissions, hydrogen’s role in industry will only grow. Consultants who understand its applications and advocate for its integration will be instrumental in shaping a cleaner, more efficient industrial future.
