So, Nicola, you've heard me say this before. That's for decarbonization more broadly and the hydrogen economy, particularly the pickups, we need a couple of three things to happen, obviously regulation with deep. We've seen that happen very much in Europe. I think your point is absolutely valid that, we see Europe provide the kind of penalties and incentives, the guidance sticks, which are allowing momentum to build in that space quite actively and aggressively. So, that was good to see. We are participating in that, whether it's gypsy funding, whether it's other incentives, whether it's the broader coalition that is looking at contract for differences to make sure that we're leveraging facilities elsewhere to support European economies. I've also said -- and of course, just to make the points in the U.S., we are encouraged to see progress happening in that area as well. Now, that the U.S. currently offers 45Q, our view is that that is inadequate for any substantial momentum to build up in the space, but I'm encouraged by -- conversations going on in the House. And hopefully the Senate that'll move some of the incentives and proposals forward in that space. So, I'm looking forward to seeing developments there quite closely. So, I guess, the other couple of things that need to happen, which I think, create the momentum that we need. And I am at the risk of repeating myself from the last call, we do need to see that the technology roadmaps ensure that the technology for either green and blue which is currently available and scalable, creates the cost curve that is necessary for large scale adoption to happen. That remains -- I won't say that the challenge that is actively being worked on, but there is a timing challenge to that. And I know take years before we get to a point, but green in particular, has the ability to have a cost-effective solution available at scale, good solutions that are available today. We provide many of those ourselves, but I recognize that there was still a scale up, that is currently lacking in the green hydrogen space. And finally, I think we need to be working very closely with making sure that the endpoint consumption in this case, if we're talking about heavy duty, vehicles, buses, or trucks, or indeed trains and ferries, that technology development in that space is happening actively. Hence the number of partnerships that we do to make sure that we're right in the middle of those developments, and we are encouraging and promoting them as much as possible. So, I know I've provided the border answer than you were looking for, but I think this was worth recapping, because these are the things that are ensuring that the momentum that we see today sustains, and you actually see investment and development in that space.
