I think there are a couple of issues here.
There is currently the potential to move hydrogen, to some degree. You can blend hydrogen with other gases and it can be moved through existing infrastructure at relatively low ratios. That is a possibility right now. Other possibilities are looking at other forms of transportation, as well as the possibility of retrofits to some existing infrastructure. Those, right now, are part of the ongoing conversation as we think about the next steps with respect to hydrogen applications.
