This came up in PR #523. It's not possible to add a finance subgroup with the commodity stream as the natural gas feedstock (which outputs natural gas in MMBTu/h) because all logic in H2I basically is "if the commodity isn't electricity then its mass, so we use kg". I think this could look like more sophisticated logic for commodity units, or (the easiest option) would be allow for a user to specify the commodity units for a finance subgroup. This would also allow for things like LCOE to be calculated (and default output) in different units, such as USD/MW*h rather than USD/kW*h
