The gas remaining in depleted and abandoned fields typically account to 20-30% of the initial volume in place. The proposed in situ hydrogen generation technology will allow converting the remaining methane reserves to hydrogen directly in situ. The reservoir is therefore converted into a ready to produce high pressure hydrogen storage cell. Reservoir conditions experimental and numerical modelling was performed to validate in situ hydrogen generation process. Hydrogen can be produced from hydrocarbons in situ from a combination of steam reforming and enthodermic methane catalytic cracking reactions. State of the art thermal simulation tools were used to model the process at reservoir conditions. A hydrogen generation process implemented at a medium size abandoned gas field will allow generating significant volume of hydrogen. In principal, converting just a few fields should cover annual world demand of hydrogen currently amounting to about 100 million tons per year. Hydrocarbon processing and transportation stages on the surface are therefore abated.
