Abstract (en)
[origin: WO2017221113A1] Process for manufacturing hydrogen from shale gas (or shale oil) in which: a) The shale gas (or oil) produced is converted into hydrogen by catalytic steam reforming or by partial oxidation by oxygen from the air in a plant set up nearby, b) The carbon dioxide generated with the hydrogen is separated from the gas mixture and recycled into the shale gas reservoir, it is used to carry out hydraulic fracturing. It may pass into a buffer reservoir. c) The carbon dioxide is finally sequestered in the borehole created for the exploitation of the gas. d) The hydrogen is used either directly in an electric power plant set up on the site and (or) injected into a hydrogen distribution network constructed for this purpose. The cost price of the hydrogen thus produced and distributed is of the order of magnitude of the price of imported natural gas having an identical energy content, this including the investments with a return time of less than four years. The invention thus makes it possible to reduce the releases of greenhouse gases to a level lower than those anticipated by COP21 (United Nations Climate Change Conference).
