Another net zero pathway is LC-NFAX2, which relies on alternative feedstocks; thus, even if chemical products are incinerated without carbon capture as they are today, a near net zero can be achieved owing to the CO2 absorbed from the atmosphere by the feedstocks. In this context, the carbon vector is from the air to the air. While this pathway does not rely on untested CCS, it relies intensively on bio-based feedstock and DAC-CCU, despite the fact that very little bio-based feedstock and even less DAC-CCU are used in practice today. Furthermore, sustainably sourcing a large amount of bio-based feedstock is considered a major challenge (Energy Transitions Commission 2021). Given the rising demand for securing food for the growing global population and the accelerating movement to safeguard biodiversity, relying on imported bio-based feedstock is a simple but risky option in terms of supply chain management, not to mention trade security and currency fluctuations. Conversely, long-term investment in the under-explored domestic supply of large-scale bio-based feedstocks for chemicals represents an opportunity.
