OXYGEN






Oxygen is just as valuable as Hydrogen in the decarbonisation of industry, as it can lower emissions from combustion processes.  

Combustion mostly occurs with air, which is made up only of ~21% oxygen, therefore requiring more fossil fuels for combustion, and contains gases such as nitrogen which gives NOx emissions when burned.

Using high-purity oxygen to replace air in combustion processes therefore presents an elegant solution to decrease CO2 emissions and fully eliminate harmful NOx emissions.

Unfortunately, oxygen from electrolysis can often not be used due to its hydrogen content, creating an explosive mix, so is instead released into the atmosphere.

Our, low-cost and high-purity, green oxygen has many applications in combustion processes and beyond.


APPLICATIONS

HEAVY INDUSTRY
Heavy industries such as steel and glass production already use oxygen in their industrial processes and have started to use oxygen combustion to improve energy efficiency, raise temperatures, and decrease emissions of CO2 and NOx.

Combustion with pure oxygen directly diminishes CO2 emissions from combustion processes as it allows for a higher flame temperature and lowers fuel consumption. Such oxygen-enriched combustion can be applied to all kinds of industrial heating processes.

NOx regulations are becoming stricter and more commonplace (e.g. across the EU) and will likely accelerate usage of pure oxygen. In the Netherlands, for example, a NOx emission trading system already exists, creating clear economic incentives to use oxygen to avoid NOx.

CARBON CAPTURE AND STORAGE TECHNOLOGIES
Multiple types of Carbon Capture and Storage (CCS) Technologies exist. Pre-combustion CCS requires oxygen in their process to be able to sequester the carbon.

Oxygen is also highly beneficial for post-combustion CCS as using high-purity oxygen in the combustion process simplifies the capturing of the CO2 afterwards.

While, the use of all types of CCS is projected to strongly increase, approximately 10% of the costs of CCS relate to oxygen, making cheap oxygen a crucial element to its widespread deployment.
