For anyone to become a leader, there's usually a scenario where there's waste hydrogen. In this case, there was waste hydrogen and people were figuring out how to collect it and turn it into something valuable. That is my understanding of where the starting point of hydrogen innovation came to light.
Then, when they're figuring out where we can actually apply the hydrogen, that's where more innovation happens on the demand side. On specific manufacturing and production industrial sites, hydrogen is an output of the process, and that's where a lot of the innovation has come from. Now we're looking at non-industrial sites and at hydrogen production within communities and stuff like that.
Usually, there's just an environment and some waste product. Someone has to turn it into something valuable and, boom, you have a market.
