Purification of Syngas to using Process Swing Adsorption with Purge Gas Recirculation (PSA-SPUR) for carbon negative hydrogen

Overview of the Demonstration
As the world moves to decarbonise and better secure the energy sector against climate change and global conflict, hydrogen is increasingly seen as a critical pathway to a secure and diverse energy mix. However, current hydrogen generation is highly sensitive to fossil fuel industry events, such as price shocks or supply chain issues, necessitating a broader mix of hydrogen production methods.
This demonstration showcases a suite of technologies, demonstrating the potential of the Wild Hydrogen Rising Pressure Reformer (RiPR) to generate carbon-negative hydrogen by separating carbon dioxide from other energy gases created in a RiPR using a pressure swing adsorption (PSA) system.

Key Findings:
• The project successfully increased hydrogen concentration from 30% to 70% by volume, highlighting the potential of PSA technology for syngas purification.
• A carbon dioxide and methane mixture was also produced, which could be further refined using additional PSA steps or alternative separation methods.
• PSA-SPUR technology demonstrated CO₂ capture at over approximately 95% purity, providing an initial pathway for carbon sequestration.
