It's a great question, Ryan. The hydrogen can be frozen, it's a smaller, lighter atom, so it takes a little bit more energy. I think it could freeze at about 100 degrees colder than does LNG. So that part of the infrastructure works. There seems to be some challenges in putting it into pipelines, right. So, we talked to the technical people, I guess the atom is so small, there is some permeability issues and whatnot. So, it's a real issue. One of the things I think is really interesting about the production of it though potentially is electrolysis if that was your feedstock for hydrogen, you could perform that onsite, potentially. So actually obviate the need for transportation, that's one significant benefit other than something to really think about. Also again depending on the feedstock, that's why I layout that feedstock page, you could use the feedstock, transport that and then have your hydrogen production on site. So, I think what's likely is you'll see distributed production is kind of the way we think about it like fill hydrogen in a box effectively, where we've got different production technologies that then travel to where they are used. That's why I'm so focused on price because when you look at the big users for the ones that leap off the page, the industrial users and the power plants and you could potentially actually create your own hydrogen on those sites. That's in effect of what's being done today, it's been done in a super-duper like dirty way. And I think it's amazing, I put those numbers there, maybe they didn't surprise you, they surprised me. I was shocked to see that actually hydrogen has a bigger market than is LNG today. The users for it are basically the refineries, right. The refineries use a lot of it for industrial purposes and of course it's used a lot in the production of fertilizers. So, for things like methanol and for urea and ammonia, in particular. One of the other things, people have talked about is, it's fairly easy to turn hydrogen into ammonia and then ship ammonia, that's done commonly, it's actually shipped all over the place. And then you can either use it as ammonia when it gets there in some way, shape or form or you have a fairly simple cracker in place and actually split it back out. So -- but your question is like spot on, a great question. It will be first, find a cheap way to make it, second, find a use for it and third, trying to figure out how to get it from point A to point B, that's actually - that is the logic chain to get from one place to the other. And we're still on one, making progress on one. Once we get to one, two is in gunsight, three will be a big part of the solution for it though, so planning for some good options.
