Insitu Hydrogen Production from Hydrocarbon Reservoirs: What are the key challenges and prospects?

Hydrogen can be produced from a variety of sources; water, biomass, fossil fuel etc. At present, nearly all industrial hydrogen production processes involve the use of hydrocarbon fossil fuel. With continuous technological advances, a shift in hydrogen production from fossil fuel sources to renewable sources is expected. CO2 emission is a major by-product of hydrogen production from fossil fuel. There is a need to reduce or completely prevent CO2 from being released into the atmosphere because of its harmful effect on the environment. One method of doing this, is to capture the CO2, another method is to produce hydrogen by thermal decomposition of hydrocarbon (by-product is solid coke).
