Energy giant Shell has worked with BASF to complete an essential stage of the green hydrogen purification process by qualifying the chemical company’s green hydrogen purification technologies, making it eligible for use in Shell’s global green hydrogen projects.
BASF’s Puristar R0-20 is used to remove remnant oxygen from the product hydrogen by converting it to water in the DeOxo Unit, before the Sorbead Adsorption Technology (SAT) dehydrates the hydrogen.
Following the removal of impurities, the hydrogen can then be used either as an energy source or chemical feedstock.
BASF claims a higher efficiency rating for its purification technology, with its SAT leaving a minial energy footprint compared to altnerative materials, in addition to having a high capacity for water and low regeneration temperatures compared to activated alumina or molecular sieves.
