The global blue hydrogen market is experiencing rapid growth, with projections indicating a significant increase from US$ 25.78 billion in 2024 to US$ 212.39 billion by 2050 at a CAGR of 19.50%. Governments in the UK and the US are supporting the transition to blue hydrogen through subsidies and tax credits, emphasizing its importance in clean energy strategies. Major players like Air Products and the US Department of Energy are investing billions in blue hydrogen projects, underlining industry commitment to the technology. Blue hydrogen is finding applications in energy-intensive industries such as oil refining and ammonia manufacturing, offering a cleaner alternative to traditional fossil fuels. Its versatility extends to potential uses in transportation, including fuel cell vehicles and aviation, indicating a broad range of applications. However, the effectiveness of carbon capture and storage technologies is crucial in determining the environmental impact of blue hydrogen. Technological advancements are driving developments in blue hydrogen production, with a focus on carbon capture and storage technologies. Steam methane reforming (SMR) coupled with CCS remains a primary method, with emerging hybrid systems like autothermal reforming (ATR) and solid oxide electrolysis showing promise for co-producing blue and green hydrogen. The global hydrogen production landscape is evolving, with a shift towards CCS-integrated projects, highlighting the nascent stage of blue hydrogen initiatives.
