Cleaner combustion, faster performance and improved safety are positioning hydrogen as a serious alternative to traditional fuel gases in heating and cutting applications.
Hydrogen is not a new gas, but its potential as an alternative fuel source is being widely realised across the global economy. Long relied upon fuels such as LPG and acetylene remain effective, yet both are tied to complex supply chains. LPG is produced as a byproduct of oil refining, while acetylene depends on calcium carbide, much of which is sourced overseas.
This reliance on imported and traded materials can expose manufacturers to volatility, particularly during periods of global economic disruption. Against this backdrop, hydrogen is gaining traction as industries seek more stable, sustainable energy options.
Coregas’ H2Cut Oxyfuel Technology is emerging as a practical solution in this transition. Already in use across industrial settings, it enables faster and cleaner heating and cutting processes. The result is a measurable lift in productivity, with reduced labour input and less time spent on post-cut cleaning and finishing.
Efficiency meets safety and sustainability
As with all industrial gases, hydrogen must be handled correctly. When it is, it offers a range of safety advantages that are difficult to ignore. Being around 14 times lighter than air, hydrogen disperses rapidly, thus reducing the likelihood of flammable gas build-up compared to LPG or acetylene.
The benefits extend beyond dispersion according to Coregas. Hydrogen supports a cooler and more controlled working environment, producing less radiant heat and a quieter, less visually harsh flame. Reduced dust emissions and improved visibility contribute to a workspace that is both safer and comfortable for operators.
There is also a growing industry focus on occupational exposure to fumes. While welding emissions have been scrutinised, heating and cutting processes can generate similarly harmful byproducts. Nitrogen oxides (NOx), including nitric oxide and nitrogen dioxide, are commonly produced when burning traditional fuel gases. These emissions are subject to strict limits set by Safe Work Australia, with further tightening expected.
Coregas believes hydrogen presents an advantage in this area. Its combustion and unique heat transfer reduces NOx emissions, supporting improved air quality and aligning with evolving regulatory expectations.
From an environmental perspective, hydrogen also offers a compelling case. It burns cleanly, producing only water as a byproduct and no additional carbon dioxide beyond what is naturally present. This positions it as a viable option for companies seeking to meet sustainability targets while maintaining operational efficiency.
The operational features are equally notable. Hydrogen’s flame characteristics allow for targeted heat transfer, enabling faster preheating and cutting. This precision not only improves efficiency but also reduces waste, delivering cleaner cut profiles and in applications like scrap cutting, minimising unsellable slag.

Expanding applications on the ground
Since the launch of H2Cut Oxyfuel Technology, Coregas has expanded its equipment range beyond hydrogen-optimised hand and machine torches. The broader offering is designed to support a range of industrial applications. For workshop and field operations, hydrogen-enabled hand cutting and heating systems provide speed and portability, with options such as the Stablecut track system offering a more portable and manual yet precise alternative to machine cutting.
In scrap cutting environments, dedicated hydrogen torches improve productivity under harsh conditions. Lower radiant heat, reduced fumes and less eye strain contribute to improved operator comfort, while faster cutting speeds enhance throughput. Preheating applications also benefit from hydrogen’s properties. Its heating curve enables quicker and more effective temperature ramp-up, particularly when combined with compressed air in specialised torches designed for targeted heat distribution where you need it.
As industries balance productivity demands with stricter environmental and safety expectations, hydrogen is moving from a niche alternative to a mainstream consideration. Technologies such as H2Cut demonstrate how established processes like oxyfuel cutting can evolve without compromising performance.
For manufacturers, the shift is less about replacing what works and more about improving it – achieving cleaner, safer and more productive outcomes in the process.
