| 概要 | To limit global warming below 1.5°C, all anthropogenic activities will have to reach net-zero CO2 emissions by mid-century. The chemical industry is responsible for about 5% of global CO2 emissions and is key to achieving net-zero targets. Decarbonizing this industry, nevertheless, faces a special challenge in that a large fraction of chemical products contain carbon. Yet, multiple technology routes are now available for producing chemicals with net-zero CO2 emissions based on biomass, recycling, and carbon capture, utilization, and storage. However, the extent to which these routes are viable with respect to the local availability of energy and natural resources remains unclear. In this seminar, I compare net-zero routes by quantifying their energy, land, and water requirements and the corresponding induced resource scarcity at the country-level, and further discuss the technical and environmental viability of a net-zero chemical industry. Furthermore, I dive into ammonia and fertilizers production to investigate the energy and food security implications of net-zero nitrogen fertilizers. Finally, I present the optimal design of net-zero hydrogen supply chains, which will be needed to supply hydrogen to chemical plants, and possibly other plants, in a world of net-zero emissions. |
