Enhanced natural gas production using CO2 injection: Application to sustainable hydrogen production

Hydrogen production, transportation, utilization, and storage: Recent advances towards sustainable energy

“…Hydrocarbon reforming is a thermal process for H2 production from hydrocarbons. The feedstock for hydrocarbon reforming is predominantly methane in its pure form or natural gas and in some cases other light hydrocarbons such as ethane, ethanol, propane, butane, and their mixtures [19]. Reforming hydrocarbons is an energy-intensive process and is triggered by the presence of components such as carbon dioxide, steam, and oxygen which act as oxidizing agents [101].…”

“…SRM is the most mature and efficient technology for H2 and syngas production. However, the major challenges associated with it are still unresolved [19]. The first challenge is the exorbitant energy cost to meet the highly endothermic SRM reaction conditions and the capital cost of heat transfer and heat-resistant equipment.…”

“…2). The retrofitting of SMR with carbon capture and storage (CCS) technology produces blue H2 [17][18][19]. On the other hand, green H2 is produced from the splitting of water molecules via electrolysis with an electricity supply from renewable sources (such as wind, solar, and others) [20][21][22].…”

Applied research on methane steam reforming properties of porous structural catalyst fabricated by selective laser melting technology

“…Steam Reforming of Methane (SRM) is the most widely used hydrogen production technology in industry, which has the characteristics of a simple process with low cost, clean and high efficiency. Its large hydrogen production can meet the needs of industrialization [1][2][3][4][5][6][7]. SRM is greatly affected by the catalyst, and the characteristics of the catalyst directly determine the effect of methane steam reforming.…”

Underground hydrogen storage: A critical assessment of fluid-fluid and fluid-rock interactions

“…There is a constant increase in global energy demand due to increasing population and global industrialization [1,2]. Currently, a significant contribution to the world's energy demand comes from non-renewable sources like petroleum, and coal [3][4][5]. The use of fossil fuels for energy is a cause for concern due to post-combustion emissions of carbon monoxide (CO), carbon dioxide (CO2), and nitrous oxide (NO2) which constitute greenhouse gas emissions [6,7].…”
