To improve energy efficiency, Technip Energies and Clariant have jointly developed and commercialized the award-winning EARTH® (Enhanced Annular Reforming Tube for Hydrogen and Syngas), a novel recuperative steam reforming technology. It is a drop-in solution for existing or new reformer tubes, reducing CO2 emissions by up to 20%, thus facilitating CO2 capturing and making blue hydrogen production more cost-efficient. At large capacities, it might be worthwhile to replace the steam methane reformer (SMR) with an oxygen-blown autothermal reformer (ATR). In this case, CO2 emissions caused by the firing of the reformer are completely avoided and renewable energy can be used for the necessary air separation. This technology is proven in numerous ATR-based Air Liquide E&C licensed and designed methanol plants, and Clariant has decades of successful experience with its highly robust and active ReforMax® catalyst series.
