Thank you.
To begin, according to us, what is totally critical is to make sure that the investment we're going to do, scaled up larger, will be based on what we could define as encore customers. No matter if the encore customer is a large industry or basin, like a captive fleet of trucks in—I don't know—an airport, what's important is that it's based on solid, reliable, relatively continuous need of hydrogen, preferably, low-carbon hydrogen, to build a demand justifying the set up of the primary production of hydrogen. That's the first step. Then it would be far easier in the second step to add multiple other types of use, including intermittent ones. When we're dealing with transportation, notably passenger vehicles for example, it's very intermittent.
That's why, according to us, it's important to create or to build the demand. There, for sure, authorities and communities can help with their own fleets. It could be buses. It could be ferries. It could be trains. All of those captive fleets have the interest of very often, if not always, coming back to their original location. That means it's limiting, to a certain extent, the importance of the investment in terms of overall supply chain or the set up to be in a position to fuel vehicles. That's the first point.
The second important point is de-risking. I'm an industrial; I'm ready to take risks. That's why, by the way, I'm asking for a certain return. Nevertheless, we need a good level of policy alignment. We need to have strategies. We need to have an overall coordination. It's the same thing for regulations, ease of doing business and permitting, typically.
At the same time, it's key for us and for all players around the table, I'm sure, to do it in a safe and sustainable way. That's something we're doing now, if you are speaking about hydrogen, for four or five decades.
Last but not least, incentives will help as there's still, and it's known, an economical gap, not negligible, between volumes we need to hit and it's the scaling up or the ramp up where hydrogen or any other fuel—it's one that's a technical breakout parameter—will be at par with the historical way of fuelling for fossil fuels or others.
In a nutshell, that would be my answer.
