Voyex II, de-hydrogenation demonstrator

We are happy to introduce you to Voyex II, a 30 kW pilot de-hydrogenation system to demonstrate the feasibility of Voyex’s zero emission power solution. Voyex’s distinctive LOHC (Liquid Organic Hydrogen Carrier), can be used both as a zero-emission alternative for heavy duty transport and industry diesel applications and as a storage and transportation medium for large amounts of hydrogen. Compared to other LOHC options, a major benefit of Voyex LOHC is that it can be used in combination with an internal combustion engine. This makes the transition to zero-emission power much less disruptive than alternative solutions on the market. 

We are therefore very excited to demonstrate this game-changing pilot installation. This installation demonstrates the mechanical system that creates a zero-emission hydrogen power system based on Voyex LOHC. With a hydrogen output at 10-12 bar, it can be integrated and connected directly to supply an internal combustion engine, or it can supply hydrogen on demand as a way of charging e.g. for hydrogen-powered machinery on construction sites. 

Voyex LOHC can be stored at atmospheric pressure and ambient temperatures, is less toxic and safer than diesel. This makes it an ideal storage medium for hydrogen. 

Anticipating market demands, the Voyex LOHC molecule has been specifically selected for its low release temperature of hydrogen. The energy (heat) present within the exhaust of an internal combustion engine is sufficient, making the installation highly efficient. As a result, only a small energy buffer is required for starting the engine, after which the release of hydrogen is fully supported by the energy already produced by the engine. This increases efficiency so dramatically that when properly executed, a well-to-wheel efficiency of 35-40% can be realistically achieved.  This is indeed far more than current options offer. The potential efficiency gained with Voyex LOHC across the supply chain, is roughly twice the currently attained efficiencies. 

 The fact that the Voyex LOHC can be used as replacement fuel for diesel, directly where you need it and in in a safe , easy and affordable manner also means that a very fine-meshed distribution network of hydrogen is possible. This solves one of the major challenges related to hydrogen.

Challenges clearly remain at this current prototype-stage. The technology is new and requires a robust and step-by-step (field) test regime before it can be scaled up. The demo-unit also needs to be integrated with an actual hydrogen engine, heat exchange, which primarily generates the challenge of ‘dynamic coupling’. Voyex is also already discussing with parties, supportive to execute actual real life tests, to plan and execute field tests in the future for the first Voyex LOHC generator set that encompasses the technology here put forward in the 30KW prototype/demonstrator.
