Drawing on survey data from 244 manufacturing firms collected between 2022 and 2023, Partial Least Squares Structural Equation Modeling (PLS-SEM) is employed to evaluate the direct and indirect effects among procurement strategies, innovation practices, quality management systems, legitimacy perceptions, and financial accessibility.

Crucially, TQM mediates the relationship between operational inputs and financial performance (β = 0.35, p < 0.01), reinforcing its role in strengthening investor confidence and institutional transparency. These findings highlight the strategic value of institutionalizing TQM in energy storage ecosystems, suggesting that embedding quality certification and outcome-based evaluations into hydrogen finance frameworks can enhance financial inclusivity, especially for small and medium-sized enterprises.
