Replacing fossil-fuelled furnaces with renewable electrical heating and cutting carbon from some heavy industries could make a serious dent in climate targets
The energy-intensive nature of upstream chemical manufacture, from cracking to petrochemical production, gives it a huge carbon footprint. Other common large-scale processes, such as steam reforming methane to make hydrogen, create carbon dioxide as a by-product, in addition to the emissions from the energy. While multiple efforts are afoot to commercialise carbon capture and storage techniques to prevent CO2 from escaping into the atmosphere, this is, effectively, burying the problem. It would be better to stop generating CO2 in the first place, or use it to create useful raw materials.
