Our pilot plant project included Honeywell Corporation’s UOP subsidiary as our joint development partner pursuant to a Joint Development Agreement dating from 2021. For more than 100 years, Honeywell UOP has been the leading international supplier and licensor for the petroleum refining, gas processing, petrochemical production and major manufacturing industries. UOP is responsible for developing and implementing some of the most groundbreaking technologies in the world over the past century. UOP’s participation in our pilot plant project added immeasurably to its value. 

Since completing the pilot plant project in the first half of 2023, we have continued to work with UOP on additional testing to round out the commercial qualifications of ZF Reactors, which we are now marketing in a joint effort with UOP.


Propelling Energy Transition Efforts Through More Efficient, Low-Carbon Hydrogen Production

[Honeywell Corporation, December 2023, https://pmt.honeywell.com/us/en/about-pmt/newsroom/featured-stories/propelling-energy-transition-efforts-through-more-efficient-low-carbon-hydrogen-production]

As part of the collaboration between Honeywell and ZoneFlow Reactor Technologies, LLC, the outcomes of the successful pilot plant testing represent significant improvements in efficiency and costs for new and existing steam methane reforming plants.



With the energy transition journey taking place throughout industries around the world, hydrogen is expected to play a significant role in advancing ongoing efforts.

Hydrogen is a versatile element that can be used for energy storage, as a power source, as an industrial feedstock and within other high-purity applications. When combined with production processes that have little to no carbon emissions as a by-product, hydrogen, often referred to as clean hydrogen, is perceived as a global energy solution that can help the world accelerate decarbonization efforts, especially in challenging areas such as the  hard-to-abate sectors.

However, despite the extensive role clean hydrogen can play, challenges such as the need to scale up its production for commercialization all while lowering costs pose a major hurdle for its wide-scale adoption.

This is where the recent conclusion of the successful pilot plant testing conducted as part of Honeywell and  ZoneFlow Reactor Technologies, LLC (ZFRT) joint agreement to commercialize the ZoneFlow™ Reactor Technology marks a significant step forward in making hydrogen production more efficient and less expensive. 


Significance of the Collaboration

Honeywell UOP and ZoneFlow Reactor Technologies, LLC had announced their collaboration in 2021 that would involve their joint efforts in growing and commercializing the ZoneFlow™ Reactor Technology.

This technology can provide an improvement in the efficiency and carbon intensity of steam methane reforming (SMR), one of the most commonly used hydrogen production processes. When combined with our Honeywell H Solutions involving  carbon capture, it enables more efficient and less expensive production of low-carbon hydrogen.


To validate the expected 15% increase in throughput over conventional catalyst pellet systems, Honeywell UOP and ZoneFlow Reactor Technologies, LLC began conducting pilot plant testing of the ZoneFlow™ Reactor in ZFRT’s large-scale pilot plant at Université Catholique de Louvain in Louvain-la-Neuve, Belgium. 

Results of the Pilot Plant Testing

Two years later, the near-commercial-level testing has validated increased steam reforming capacity by at least 15% 1 in terms of feed flow compared to conventional state-of-the-art pellets, with no higher methane slip and without increasing the maximum tube skin temperature or pressure drop. The increase of hydrogen production allows for the SMR to convert hydrocarbon feeds such as natural gas or naphtha and steam into synthesis gas.

“The pilot plant tests successfully concluded a decade of development and engineering work by my ZoneFlow colleagues. We look forward to rapid commercial introduction of the ZoneFlow Reactors with Honeywell, whose support has been essential in bringing us to this point,” said Bruce Boisture, President of ZoneFlow Reactor Technologies. “In the meantime, our work on other groundbreaking SMR technologies continues apace, with more announcements to follow later in the year.”

With over 800 steam methane reforming units worldwide and a similar amount used for ammonia and methanol production, the success of the pilot testing represents capital savings for new steam methane reforming plants and higher productivity for existing plants.


Influence on Energy Transition Efforts

The combination of our H solutions and domain expertise with ZoneFlow’s Reactor technology is helping enable high-value creation for both new and existing steam methane reforming units.

Given that ZoneFlow reactors can increase hydrogen production with existing assets, this ready-now technology can play a major role in the energy transition as refineries look to burn hydrogen instead of natural gas to lower their carbon emissions.

As the urgency for global decarbonization intensifies, the successful pilot testing represents is not only a remarkable advancement towards the scaling up and commercialization of low-carbon hydrogen production, but also signifies a major influence on the energy transition journey.
