Honeywell introduces Liquid Organic Hydrogen Carrier

Honeywell UOP has introduced its Liquid Organic Hydrogen Carrier (LOHC), a solution that enables the long-distance transportation of clean hydrogen. This cost-effective solution can help meet the growing requirements for hydrogen use across various industries by leveraging existing refinery and transportation infrastructure.

While hydrogen is expected to play a critical role in reducing greenhouse gas emissions, at standard conditions, it is a flammable gas with low density and cannot be transported efficiently in a gaseous form. Current solutions for transport include liquified hydrogen and chemical carriers such as ammonia, which would require additional infrastructure to accommodate new volume. Honeywell UOP’s LOHC solution utilizes existing refining assets and infrastructure to create and transport the carrier.

In the Honeywell LOHC solution, hydrogen gas is combined chemically through the Honeywell UOP Toluene Saturation Process into a convenient liquid carrier compatible with existing infrastructure. The carrier can then be transported in the same way as gasoline or similar hydrocarbons.

Once at its destination, the hydrogen is recovered from the carrier using the Honeywell UOP Methylcyclohexane Dehydrogenation Process. Existing idle oil refining assets can be revamped to release the hydrogen from the liquid carrier for use in multiple commercial and industrial applications. The carrier used in the Honeywell LOHC solution is readily available and requires minimal makeup.

LOHC is part of Honeywell’s Green Hydrogen program. The program leverages decades of research and development and experience in developing and manufacturing market-leading membranes and catalysts for gas processing, refining, steel, and petrochemical industries, as well as the experience in the most recent development of novel membranes for battery and power applications.

Honeywell recently committed to achieve carbon neutrality in its operations and facilities by 2035. About half of Honeywell’s new product introduction research and development investment is directed toward products that improve environmental and social outcomes for customers.

I am trying to get a hold on the energy efficiency of this cycle, but have not had much luck, although of course I am handicapped in not having the background in chemistry which would enable swift comprehension of the stuff I dig out, and importanty, the ability to set it in context.

The nearest I have come accross is this:

https://technology.matthey.com/article/30/4/174-182/

But I have not been able to sort out from extraneous information relating to particular cases such as where it is shipped from Texas to California for use, with costs so on about that, enough to get back to the basic question:

If at the same site, ignoring transport etc, you cycled toluene to Methylcyclohexane and back again, what is the energy efficiency?

Nothing really new here except Honeywell UOP Catalysts. This is basically a “Blue H2 Process” using Natural Gas.
Remember this GCC post on the Chiyoda SPERA LOHC process:

Here is recent news from Chiyoda:

Key takeaway is that this is a “ cost-effective solution can help meet the growing requirements for hydrogen use across various industries by leveraging existing refinery and transportation infrastructure.”

It is found that the energy efficiency of the LOHC has
a highest number of 69.17% and 88.74% with and without energy recycling respectively
The results also show that the energy efficiency of LOHC technology is somewhat lower than those of 70 MPa and 35 MPa high-pressure storage methods.

@SJC

Many thanks.

That sounds 'good enough' for shipping etc, and avoids the problems of toxicity of ammonia, although the latter has established infrastructure to handle it, and a lot of experience.
