The logic is the Steam Methane Reforming (SMR) process itself - extracting hydrogen from natural gas, methane. Hydrogen for oil companies is utilized to get the sulfur out of gasoline.
In fact 95% of the hydrogen produced in the U.S. comes through methane reforming by applying an intense steam pressure into the gas. The product is hydrogen along with carbon dioxide (CO2), carbon monoxide (CO).
For the oil companies Steam Methane Reforming is considered as economical. DOE on the other hand viewed it as deterrent in the measures to arrest the global climate change issues since the SMR process' accompanying emissions, CO2, is said to be twice the amount of hydrogen produced. So NO thank you for that.

Actually, it has long been used for oil refineries and some of its produced was used for food processing and for medical applications. And have flown rockets and other space craft for seeking some truths in the outer space... So thank you for that.
In another light, DOE supports research on three electrolyzer type: Alkaline, Solid Oxide and the Polymer electrolyte Membrane (PEM).
