Biomass to Sustainable Energy
White Hydrogen

Pathway to a bright and sustainable energy future


In the future, hydrogen is expected to be the most critical renewable energy carrier, and its predominant production from fossil fuels such as coal and gas is not sustainable due to its high pollution and carbon dioxide emissions. However, H2-XERONOX® technology provides a sustainable and environmentally friendly alternative for producing white hydrogen.

The H2-XERONOX® system utilizes a thermal process with Harmonic Resonance Combustion (HRC) to generate the necessary thermal energy for converting carbon-based matter to hydrogen-rich synthesis gas (syngas). Syngas samples exhibit high levels of hydrogen (H2), which can be extracted via a pressure swing adsorption (PSA) purification process to obtain high-purity hydrogen H2. Additionally, the leftover waste tail gas can be recycled to supply all of the process’s thermal energy requirements through the HRC, making it self-sustaining, renewable, and carbon-neutral.

The H2-XERONOX® process is a thermal technology that operates in a near oxygen-free environment, setting a benchmark for converting carbon-based matter to hydrogen H2 efficiently and safely. Furthermore, the process is highly effective and super-efficient for converting renewable organic and carbon-rich feedstock into hydrogen.

H2-XERONOX® usage examples

The demand for hydrogen is rapidly increasing, especially in developing nations that require energy for economic development and poverty reduction. Additionally, the world’s agricultural sector relies on hydrogen for ammonia fertilizers to support food production for a growing population. Given these circumstances, H2-XERONOX ® technology offers the most promising pathway towards a sustainable and clean energy future.


Protecting the environment and decarbonizing the energy sector has become a major issue worldwide.

In the energy, transportation, and manufacturing sectors, only renewable and sustainable energy resources with high energy content should be considered and explored for future needs. In addition, these resources should have minimal impact on the food chain, water supply, land use, and environment. One such resource is crude glycerol, a carbon-neutral by-product of biodiesel production that is abundant and low-cost.

Delafield Pty Ltd, based in Carbrook, Australia, has developed the H2-XERONOX® technology, which offers an unparalleled engineering solution for safely converting carbon-based renewable resources to renewable hydrogen (H2). This technology has been analyzed with Shimadzu gas chromatograph GC-2014 at The Australian Institute of Bioengineering and Nanotechnology at the University of Queensland, confirming its high H2 content, approaching the theoretical maximum conversion rate. In addition, the H2-XERONOX® technology ensures thermodynamic efficiency and system technology development while minimizing any negative impacts on the environment.

H2-XERONOX® versus Gasification

Gasification technologies currently in use operate within the temperature range of 400-850°C and rely on the partial combustion of feedstock to sustain the gasification process. These air-breathing gasifiers produce low-quality syngas and harmful air pollution emissions. Additionally, the operating temperatures limit the types of feedstock that can be processed.

In contrast, the H2-XERONOX® thermal process utilizes recycled hydrogen and PSA tail gas in a technologically advanced and environmentally friendly process that operates in a near oxygen-free environment. This results in the complete decomposition of the feedstock, including char, tar, soot, and solid waste, to produce pure syngas and a small amount of residual carbon. This process is cost-effective and minimizes environmental impact.

At the core of the H2-XERONOX® technology is the Harmonic Resonance Combustion (HRC), which operates in a nearly oxygen-free environment and acts as the central thermal heat source. This system, combined with the PSA, facilitates unparalleled efficiency and a self-sustaining process without requiring external energy sources. As a result, the impact on the environment in terms of air pollution and global climate change is greatly minimized. The H2-XERONOX® technology represents a significant step forward in the efficient and clean conversion of carbon-based matter to hydrogen, paving the way for a cleaner energy future.
