Sorption enhanced steam reforming with CCUS (methane)


Technology Description

Sorption Enhanced Steam Reforming (SESR) is a pre-combustion CO2 capture process in which natural gas is reacted with steam in the presence of a CO2 sorbent and reforming catalyst. The CO2 is absorbed continuously over the absorbent, and thus removed from the reaction, which allows for shifting the reaction equilibrium towards the products, increasing conversions. It allows the production of decarbonised H2 and a concentrated CO2 stream suitable for transport and geological storage (or reuse).

Relevance for Net Zero

Sorption Enhanced Steam Reforming can decrease significantly the CO2 emissions associated with hydrogen production and could play an important role in net zero pathways, particularly for the creation of new production capacities, as long as the CO2 is permamently stored and upstream emissions of the fuel supply are minimised or completely avoided. However, its deployment is expeted in the medium- to long term due to its low TRL
