White Hydrogen and the H2-XERONOX technology

What is the White Hydrogen process and H2-XERONOX® technology?

In its basic form, the process and technology can converts carbon-based waste such as waste cooking oil and glycerol via a safe and efficient thermal conversion process to hydrogen-rich syngas. At the core of this technology is a Harmonic resonance combustion (HRC) system that provides all thermal energy and steam for this thermal conversion process. Following the thermal conversion, the hydrogen-rich syngas passes through a pressure swing adsorption (PSA) system, selectively separating various gases where high-purity hydrogen (99.999%) is recovered. The relatively low caloric value tail-gas from the PSA separation is then directed back to the HRC and used for heat and steam requirements.

Our hydrogen technology in comparison with current electrolysis methods

The key difference of our technology for hydrogen production over other more conventional methods such as splitting water using electricity (electrolytic) or sunlight (photolytic) is that H2-XERONOX® technology is less energy-intensive and hence more economical than the electrolytic and photolytic processes; currently, electrolysis requires about 55kWe and 9 litres of purified water with assumed efficiency of 60% to produce 1 kg of hydrogen. The H2-XERONOX®, in comparison, is a thermal-chemical conversion process that uses carbon-based waste to produce hydrogen-rich synthesis gas and re-use part of the syngas to provide thermal energy for the conversion process, making this loop process a self-sustaining, energy-efficient, green, low emission and carbon-neutral technology.

Position of H2-XERONOX® technology in a developing Hydrogen market

With the White Hydrogen and H2-XERONOX® technology, Delafield could play a major role in developing an emission-free hydrogen market; our modular and scalable design for distributed hydrogen-rich syngas or pure hydrogen with further processing into Ammonia as agricultural fertilizers or other products. The patented H2-XERONOX® technology, with unparalleled efficiency, is the most economical and environmentally friendly technology available for Hydrogen production and, more particularly, the production of White-Hydrogen, produced from waste.

What is the potential for White-hydrogen?

Looking at the global production of hydrogen, we see that 43% is used to produce Ammonia, 52% for refineries and 6% for other usages. The ever-increasing world population and consequently the increasing demand for food production will require a large amount of ammonia for agriculture fertilizers; other high hydrogen demand will come from refineries and chemical industries for the production of fertilisers and pharmaceuticals as well as hydrogen for use in fuel cells and methanol from hydrogen for automotive and transport industry, all requiring low carbon emission fuels. H2-XERONOX®  provide the best “green” technology for the production of clean White-hydrogen.

The future for Delafield and H2-XERONOX®

We have seen a clear shift towards a low carbon economy, and Delafield can provide a section of the market with its safe and efficient H2-XERONOX® technology; we believe that the hydrogen market, in general, is looking for the most cost-effective production and cleanest method to produce hydrogen from the carbon-neutral feedstock. H2-XERONOX® offers an unparalleled safe technology for a carbon-neutral and sustainable production of White-hydrogen at a low cost.


  • H2-XERONOX technology demonstrated that it is possible to produce hydrogen from carbon-based waste and to have a net zero-carbon footprint.
  • The H2-XERONOX system is sized to fit in 20-foot containers, processing one ton of carbon-based feedstock per day and producing hydrogen-rich syngas for power generation or purification into pure hydrogen with pressure swing adsorption.
  • H2-XERONOX is a solution for the ever-growing global waste problem, a market valued at billions of dollars. The H2-XERONOX process does not burn or incinerate waste but uses a patented HRC system and thermal conversion technology. The hydrogen economy, which is growing rapidly, is expected to reach $2.5 trillion by 2050.
