Hydrogen generation device (VHR)

This is an on-site gas generation device that generates hydrogen using natural gas as the main raw material, utilizing a reformer developed independently by our company.

1. Achieving the industry's smallest NG raw material unit By adopting a highly efficient heat recovery, heat utilization, and hydrogen purification process, we have achieved the industry's smallest NG raw material unit of 0.34 Nm3/Nm3-H2 (expected value). ■ Unique reformer tube heating structure and integration of high-temperature processes (hot box) Our unique reformer tube heating structure enables uniform reforming efficiency, and by integrating high-temperature processes into a hot box, we achieve efficient heat utilization. ■ Thorough heat recovery process We employ a process that allows for thorough heat recovery. Additionally, by recovering off-gas from the PVSA, we minimize the fuel consumption of natural gas. ■ Purification technology Hydrogen purification is achieved through the vacuum swing adsorption method (PVSA), improving the recovery rate from the usual 70-80% to over 90%. 2. Environmental aspects Compared to our conventional model "VH," we have reduced CO2 emissions per unit of hydrogen by 10%, contributing to the reduction of CO2, a greenhouse gas.
