Today, innovative companies are buying CO2 not just to use and release it, but to permanently sequester it or transform it into valuable products. In the construction industry, companies are purchasing CO2 to inject into concrete during the mixing process. The CO2 chemically reacts with the cement, mineralizing into a solid that permanently traps the carbon while actually increasing the compressive strength of the concrete.
This reliance on byproduct capture creates a highly volatile market. Because CO2 is a secondary product, its availability is entirely dependent on the economic health and seasonal operation of the primary industries. For instance, ammonia plants often schedule maintenance shutdowns during the summer months when fertilizer demand is low. This predictable drop in production frequently leads to regional CO2 shortages precisely when the food and beverage industry needs it most for summer ice cream and beverage production. Furthermore, when global natural gas prices spike—as seen in Europe in the early 2020s—ammonia plants (which use natural gas as a feedstock) often shut down because they become unprofitable to operate. These closures inadvertently trigger severe CO2 shortages, leaving food processors scrambling and prices skyrocketing. buy co2
Perhaps the most exciting frontier in purchasing CO2 is the synthesis of sustainable aviation fuels (e-fuels) and plastics. By combining captured carbon dioxide with green hydrogen, chemical companies can create synthetic hydrocarbons. When airlines or freight companies buy these synthetic fuels, they are participating in a closed-loop system where the carbon emitted during flight is the same carbon that was previously captured from the atmosphere or industrial chimneys. Today, innovative companies are buying CO2 not just
