Low Carbon-Intensity Hydrogen Production Pathways

This technical report discusses the production, distribution, and use of low-carbon intensity hydrogen in secondary aluminum melting. It outlines the significant role of hydrogen in reducing greenhouse gas emissions, particularly in hard-to-abate sectors where electrification is not feasible. The report details the processes for hydrogen production, including steam methane reforming (SMR), blue hydrogen, and green hydrogen, emphasizing the importance of low carbon intensity in hydrogen production methods. It presents various large-scale hydrogen projects initiated by Air Products, including those in Edmonton and Louisiana, which aim to capture and sequester CO2 emissions. The report also addresses the safety considerations associated with hydrogen use in industrial applications, highlighting the need for specific design features to prevent leaks and ensure safe operation. Additionally, it discusses the potential for hydrogen to replace hydrocarbon fuels in secondary melting furnace operations, thereby contributing to decarbonization goals.
