To meet the global goal of net zero emissions by 2050, a combination of low-carbon energy sources will be needed to replace fossil fuels. Hydrogen has the potential to compliment other renewable energy sources to meet future energy needs. The research documented here explores the economic and technical feasibility of generating hydrogen within hydrocarbon reservoirs (in-situ) using electromagnetic-assisted catalytic heating. The process was analyzed in terms of cost, energy input, efficiency, GHG emissions, and water usage. The results show that this process can be a feasible way to generate hydrogen at input energy rates between 5 - 25 kWh/kg H2, which result in competitive production costs of around $1.00 to $4.50/kg H2, using 100% grid power at a price of $0.08/kWh. Generating hydrogen within hydrocarbon reservoirs would allow the associated GHG’s from the process to remain underground, compared to having to be collected and sequestered for above ground processes.
