The Global Brown Hydrogen Market, valued at USD 29.6 billion in 2023, is anticipated to reach USD 45.9 billion by 2033, growing at a CAGR of 4.48%. The primary method for brown hydrogen production, coal gasification, emits substantial carbon emissions. Despite concerns about the environmental impact, the sector is expanding due to the increasing demand for ammonia production in industries like chemicals and petrochemicals. North America leads the market share, driven by a demand for sustainable energy sources. Europe is predicted to see rapid growth, emphasizing the significance of hydrogen technologies in achieving net zero emissions. The coal gasification without carbon capture and storage segment is prominent in the market, particularly in regions like China and the Asia-Pacific due to its cost-effectiveness. Major global brown hydrogen producers include Saudi Arabia, Indonesia, China, India, Russia, and the United States. The iron and steel industries are also incorporating brown hydrogen as an extra-reducing agent in blast furnaces. Overall, the brown hydrogen market is poised for growth, propelled by technological advancements and increasing applications in various industries.
