Economic assessments of hydrogen production processes based on natural gas reforming with carbon capture

摘要

Hydrogen is a promising energy carrier for the future low carbon economy as fuel or chemical for various industrial applications (e.g. heat & power, petro-chemical, metallurgy etc.) as well as for transport sector [1]. Hydrogen can be obtained by various methods, the most important involving the usage of fossil fuels (e.g. hydrocarbon catalytic reforming or coal gasification). In order to decarbonise heat & power sector as well as transportation sector, the fossil fuels need to be efficiently converted to hydrogen and the resulted CO_2 to be captured and then used/stored. The Carbon Capture, Utilisation and Storage (CCUS) technologies are promising options of efficiently combating climate change (by significantly reducing greenhouse gas emissions) as well as continuing of using the fossil fuels (which are predicted to remain the backbone of energy system at least in the short to medium terms) [2].
