“…A summary overview of industrial pathways for hydrogen production along with their compatibility with CCS (or CCUS if utilization is considered as well) applications is shown in Figure 20. Technological interventions that impact multiple pathways include both CCS (thermochemical and biochemical energy-dependent pathways) [162] and redox-based chemical looping cycles (thermochemical) [50,68,[163][164][165][166]. Industrial adoption of these pathways ranges from established processes to experimental and frontier technologies at labscale [167] (for each pathway, an expanded diagram of current and potential material and energy sources are presented in Figure 21).…”
