One of the most promising routes to take the next steps on the road to full decarbonisation is carbon capture and storage (CCS) from existing combustion processes, such as cement production or electrical power generation.
In the mid-term, there are also several pilot project proposals to construct steam methane reformers, or auto thermal reformers to produce hydrogen for heating and mobility applications. CCS is an integral part of these schemes to ensure that they produce blue hydrogen and play a role in sustainable decarbonisation.
The concept of CCS is to recover carbon dioxide (CO2) from industrial process gas emissions and inject the CO2 deep into the ground for long-term storage. We can thereby reduce CO2 emissions to our atmosphere and slow down climate change. For sure, when we use CO2 to freeze food or carbonate beverages the need for using a high purity gas is abundantly clear. But with the basic idea of pumping CO2 underground, why would ‘purity’ ever come into question?
