The combustion of fossil fuels is widely thought of as the cause of global CO2 emissions. While it is the major contributor, many process industries are large emitters as well, and many of those have few alternative technologies to reduce CO2 production. CF Industries, a large manufacturer of hydrogen and nitrogen products, has signed an agreement with ExxonMobil to capture and store CO2 generated by the company’s large Louisiana manufacturing complex. The development of this large-scale blue ammonia system may make ammonia a viable alternative as a motor fuel as well as an important chemical feedstock. Want to watch this podcast as a video?
