      abstract     = {Combining DAC and SOEC powered by renewable energy offers a
                      promising solution for producing methanol in region with
                      abundant renewable energy but with limited fresh water
                      supply. However, there are technical challenges that must be
                      overcome for their implementation, particularly for the SOEC
                      system. SOEC system is a key technology in overall process
                      as it directly governs conversion efficiency, carbon
                      deposition risk and critical for efficient water management.
                      Therefore, SOEC system must be carefully operated to avoid
                      carbon deposition and minimal water utilization.This
                      presentation evaluates two SOEC designs—low and high
                      utilization designs—that were previously proposed. Results
                      demonstrate that the stoichiometric number (SN) can be
                      optimized for the target range of 2.01 to 2.05 required for
                      methanol synthesis by controlling utilization and H2O/CO2
                      ratio. Heat integration and water recycling further improved
                      the low utilization design by $10.4\%$ in energy efficiency
                      and $42.2\%$ in water management, enabling carbon-safe SOEC
                      operation with minimal freshwater consumption.},
