In cases where the goal is to produce hydrogen (H2) from coal without power export, the overall flow arrangement can be further simplified. Figure 3 is a block flow diagram for producing H2 from coal with minimal power generation. Onsite power generation is kept to a level to meet internal consumption, and if necessary, some power can also be imported.
