Case Studies

Huineng Group had waste hydrogen and a fleet to fuel. Hydrexia delivered a complete purification-to-dispensing system that runs 100+ fills a day — with zero failures and a backup supply that's never been needed.

Hydrexia's MHx Solid State Hydrogen Storage offers a safer, simpler way to move and store hydrogen at scale. Built into a standard 20-foot ISO container, the system holds 1,000 kg of hydrogen using metal hydride technology, allowing it to be handled and transported just like any other shipping container — no specialized infrastructure required.

When Amino Chem (Annuo) needed industrial-scale hydrogen to feed five separate downstream processes — dye intermediates, steel blanketing, and three chemical production lines — they needed one plant that could match a wide range of demand at 99.999% purity, every hour of every day. Hydrexia designed and delivered a complete SMR-PSA plant that has been running on spec since 2021.

A naturally CO₂-rich oil field had a problem most operators would call an opportunity in disguise — volcanic CO₂ degassing alongside the hydrocarbons. Hydrexia delivered a fully integrated, automated, and relocatable system that captures the raw field gas, separates and dries the CO₂, liquefies it, stores it, and loads it onto tankers for Enhanced Oil Recovery. The plant has been running since 2022 with no unplanned outages.

Chongqing Wintinwe Chlor-Alkali was venting a hydrogen-rich waste stream while its own campus consumed hydrogen for steel blanketing, chemical processing, and merchant tube-trailer filling. Hydrexia delivered an integrated, automated PSA-and-TSA purification system that turns 30 million Nm³ of waste gas per year into 8,000 kg/day of 99.999% hydrogen — all feeding the same campus that produced it. The plant has been running since 2017 with no failures in nine years.
