Carbon Capture, Hydrogen Storage, and Chemical Looping for Energy and Oil Recovery
This community develops the chemical and engineering processes for capturing carbon dioxide, storing and producing hydrogen, and recovering oil from reservoirs, primarily to enable low-carbon energy systems and enhanced resource extraction.
The work centers on adsorption and absorption materials, such as activated carbon and porous structures, for CO2 removal. It also covers chemical looping combustion using oxygen carriers like calcium and iron, thermochemical energy storage, and direct air capture. A significant portion addresses the storage of hydrogen and carbon dioxide in underground reservoirs, including depleted gas fields and coalbeds, as well as the use of CO2 for enhanced oil recovery. The research frequently applies machine learning to optimize these processes and characterizes the pore structures of materials used for gas separation and storage.
The community is most prominent in Carbon research, accounting for 5.6% of all tracked Carbon papers, and Hydrogen research, where it represents 2.1% of the total. It also holds a 2.1% share of Sulfur research, driven by hydrogen sulfide handling and removal.
The community comprises 31,220 papers, with the highest publication volume in Fuel, International Journal of Hydrogen Energy, and Chemical Engineering Journal.
Recent work includes the development of biomass-derived porous carbons for low-energy CO2 capture, the optimization of carbon pricing in oilfield CO2-water alternation, and the assessment of geologic carbon storage limits.
