A new liquid hydrogen production facility was constructed to cater to the increasing demand from fuel cell electric vehicles (FCEVs). The facility implemented a robust pre-treatment system by Kurita to convert municipal water into demineralized water essential for hydrogen production. Hydrogen serves as an energy carrier powering fuel cells that convert it into emission-free electricity, benefiting from fast refueling and extended travel ranges. Compared to battery electric vehicles, FCEVs offer quicker refueling and longer travel distances, particularly for larger vehicles like trucks and buses. The global push for electric vehicles to reduce carbon dioxide emissions highlights the significance of hydrogen in curbing greenhouse gases. Liquid hydrogen production facilities utilize cryogenic tanker vehicles for efficient transport to fueling stations. Kurita's multi-stage filtration system ensures the production of high-quality demineralized water for hydrogen production. This system includes VertaCell media filters, U-Flex ultrafiltration, and Flux RO systems to eliminate contaminants and achieve desired water quality. Additionally, automated control systems optimize operational efficiency and longevity. By meeting water quality standards, the facility supports the growth of FCEVs by providing hydrogen to local fueling stations, contributing to global efforts for sustainable transportation and pollution reduction.
