The rational design of transition metal oxide electrocatalysts for sustainable energy conversion demands a mechanistic understanding of dynamic electronic structure reconstruction under operating conditions, yet the experimental platforms for capturing such transient phenomena remain fragmented and profoundly underdetermined by static post-mortem analysis. This paper proposes a large-scale research infrastructure that interweaves digital twin architectures with high-throughput operando spectroscopy to achieve continuous, in silico–in situ coupling of catalyst electronic evolution. We establish a system framework in which multi-modal synchrotron-based X-ray absorption and emission data streams are ingested by a continuously updating computational replica of the electrode–electrolyte interface, enabling real-time inference of oxidation state dynamics, orbital hybridization changes, and the emergence of many-body electronic configurations. The architecture is examined through the lenses of data orchestration, transmission latency, cyber-physical synchronization, and semantic interoperability between experimental beamline control systems and predictive machine learning backbones. We dissect structural trade-offs between model fidelity and computational tractability, and outline governance protocols that address data provenance, algorithmic fairness across materials families, and the long-term sustainability of shared digital twin repositories. Particular attention is given to the challenge of capturing rare electronic events—such as the formation of Zhang-Rice singlet states—that decisively influence catalytic turnover but are easily missed in traditional intermittent characterization. By mapping the full lifecycle of operando data onto a digital twin continuum, this work articulates the socio-technical requirements for transforming solitary laboratory discoveries into a federated, robust, and equitable knowledge ecosystem for electrocatalysis, with implications extending to national synchrotron facilities, materials acceleration platforms, and global energy policy frameworks.
