Increasing blue hydrogen production affordability

摘要

Large-scale,affordable,"blue"hydrogen(H2) production from natural gas,along with carbon capture,utilization and storage(CCUS),is necessary to bridge the gap until large-scale H2 production using renewable energy becomes economic.The cost of carbon dioxide(CO2) already makes blue H2 via steam methane reforming(SMR) competitive against gray H2(without CCUS),and a newly available process3 based on gas partial oxidation(POX) technology and pre-combustion CO2 capture solvent technology further increases the affordability of blue H2 for greenfield projects.
