Liquid Organic Hydrogen Carrier


Carrying the Future of Energy: Honeywell Liquid Organic Hydrogen Carrier

Honeywell’s Liquid Organic Hydrogen Carrier (LOHC) squares the circle to move to a hydrogen-powered future. Overcoming the challenges of hydrogen transportation, LOHC enables a more efficient, effective, and safer way to ship and store hydrogen using existing infrastructure. With more cost-effective long-distance transport, we can match international supply and demand for hydrogen and enable it to play a critical role in the energy mix as we move to carbon-neutral economies.


A better way to travel

Colourless, odourless, tasteless, with low density and a high risk of leakage as gas, hydrogen is usually transported as either a liquid or in ammonia or methane over long distances.

LOHC addresses the shortcomings of existing methods: 

  • Less flammable and cheaper to transport than liquid hydrogen, which is highly explosive, suffers a high boil off, and requires costly vessels and new dedicated infrastructure.

  • High purity, unlike hydrogen recovered after reconversion from methanol

  • Non-toxic, unlike ammonia with its safety and environmental concerns, with at least as cost-effective reconversion, without purity concerns.

LOHC is a cost-effective and safer carrier for clean hydrogen, which can even use existing refinery assets1

Honeywell LOHC is based on proven Honeywell UOP technologies used by commercial operators for decades.

Our UOP Toluene Hydrogenation process achieves over 99.5% conversion and selectivity2, requiring extremely low fresh toluene make-up and catalyst system stability with examples over ten years without regeneration. It offers minimum hydrogen solution losses and no continuous catalyst make-up or solid waste disposal issues.

Compared to alternatives, it offers significant benefits2:

  • >10-year catalyst life 

  • No continuous catalyst make-up or waste  

  • 7% lower cash cost of production 

  • $9.3M higher NPV 

The MCH Dehydrogenation Process achieves the highest conversion and selectivity towards toluene. The potential to retrofit existing fixed bed and continuous catalyst regeneration (CCR) Platforming units dramatically reduces the overall investment cost for hydrogen transportation.

Compared to alternatives, It is a more effective solution3:

  • 5% higher toluene selectivity 
  • 10% higher H2 yield  
  • 30% lower cash cost of production  
  • $12.9M higher NPV
