Established Hydrogen Technologies to Support Decarbonization

Scale depends on matching the appropriate technology pathway to your existing infrastructure and energy economics. Factors to consider include: 
 

• Capital efficiency: Blue hydrogen technology may utilize existing hydrocarbon infrastructure, while LOHC retrofits current refinery assets. Green hydrogen requires renewable energy sourcing but avoids feedstock volatility.

• Risk mitigation: Start with established technologies that integrate with your current operations. Honeywell's 50+ years in hydrogen processing means you benefit from validated equipment and documented performance curves.

• Phased approach: Our Plant CDO tool can help evaluate pathways upfront to minimize LCOH before major investments. This may help avoid costly retrofits and help you scale at your pace.

Purity requirements can vary significantly by application. Matching them correctly helps prevent catalyst poisoning and process inefficiencies. When matching purity specifications, it is important to consider: 

• Application-specific requirements: Fuel cells need 99.999%+ purity (ISO 14687-2 standard), as does refinery hydroprocessing. Ammonia synthesis and methanol production accept lower specifications but benefit from impurity control. ¹

• PSA system flexibility: Honeywell's Polybed PSA systems can offer 99.9% to 99.9999% purity with 80-91% hydrogen recovery.² Organizations can customize systems to balance purity against recovery economics for their specific downstream needs.

• Avoiding catalyst contamination: The PSA process can approach near-complete impurity rejection, helping keep sub-ppm levels of oxygen, water, nitrogen and carbon oxides out of product streams.³ This can help prevent costly downstream catalyst deactivation and can extend run times between regenerations.

We provide integrated solutions across the hydrogen value chain from production through end use. Our portfolio covers three areas of support: 
 

1. Production technologies: Green and blue hydrogen technology, carbon capture capabilities, PSA purification and catalyst-coated membranes help produce high-purity hydrogen.

1. Control and optimization: Honeywell Protonium solutions help reduce energy consumption and help lower LCOH through our Plant CDO, Hydrogen Electrolyzer Control System (HECS) and Unified Control and Optimization Systems (UCO).

1. Transport and storage: LOHC can enable cost-effective long-distance transport by leveraging existing infrastructure rather than requiring dedicated hydrogen pipelines.

Our approach integrates these solutions to work together across varying operating modes and conditions. With 50+ years of experience in hydrogen technologies, we can help you move from initial scope definition through commissioning while helping manage technical and operational risk.
