Net-zero chemical production can be achieved through electrification, biomass-based processes, and carbon capture, utilization, storage. However, these net-zero pathways require more resources than business-as-usual processes. One possibility to produce chemicals at a lower resource consumption is the combination of based on locally available resources. This study determines optimal combinations for producing with emissions that minimize use renewable energy, land, water while complying local waste biomass CO2 storage availability. Waste defined as residue does not compete land other sectors. The analysis performed worldwide country level considers ammonia, methanol, plastics, which, when combined, account ∼5% global emissions. Findings show that, considering individually, preferably used ammonia whereas capture deployed plastics production. At same time, mixed strategy using storage, biomass, allows one achieve industry nearly 60% reduction in energy 90% consumption, respect single-pathway strategies. Finally, we find adopting portfolio minimizes reduced by 70% cost an increase only 5%, compared minimum-energy portfolio.

Some of the issues concerning energy security and climate change can be addressed by employing nuclear power (NP) to supply required for conversion carbon dioxide (CO2) into chemicals, products, materials. Nuclear represents a neutral source that generated sustainably, reliably, consistently. plants (NPPs) could in form heat, electricity, ionizing radiation drive CO2 chemical reactions underpinning NP-to-X type pathways. processes are either commercially available or emerging technologies at different developmental maturity stages. This work reviews published literature (articles patents) reports R&D results understanding development processes, as well efforts integrating NPPs (CPs).
