A Microflow and Bioinspired Dendritic Topology Optimization for CO 2 Capture, Utilization and Storage Hubs in China: Integrating Microfluid Dynamics with Macro-Scale Infrastructure Design

High Resolution Image Download MS PowerPoint Slide Large-scale carbon capture, utilization, and storage (CCUS) is pivotal for global net-zero transitions, yet its deployment is constrained by suboptimal pipeline network designs that oversimplify techno-economic models, enforce rigid topologies, and computation bottlenecks. Here, we present a preferential-flow approach in porous and bioinspired algorithms that bridge microfluid dynamics and macroscale infrastructure design to address these bottlenecks. It mimics pore-scale preferential flow, or piping flow, in porous media, in which fluids naturally follow the least-resistance paths. This algorithm leverages the mathematical similarity between microscale hydraulics, pipeline flow, and cost models to facilitate cost-optimized network evolution. Nationwide simulations reveal that standalone CCUS projects in four coal-based energy and industrial sectors achieve 5.7 Gt/a at levelized costs of 80% emission reduction at
