Today, we are faced with ever-growing concerns surrounding greenhouse gases, and the recent Paris Climate Summit is an attempt to remedy this outstanding fact. Applying CO2 in industry – from beverage carbonation to food freezing, and metallurgical applications to usage as a weak acid – represent means of making money from the commodity, but not a net reduction of airborne emissions.
The latter must be a deliberate effort via a wide range of tasks, for example from EOR to diverting CO2 streams to aquifers, and from the potential for harvesting significant algae strains for biodiesel usage to enlarging the footprint of forests.
On the other hand, the merchant CO2 somehow touches all of us on a daily basis, and is intimately involved in the application, sale, efficiency and utilisation of the product, rather than concerns for CO2 emissions which add to the carbon footprint.
