So Colin, I think as it relates to our customer mix, right? I think majority of the opportunity if we were to think about this basic engineering design packet, right, that we talked about 4.5-gigawatt, a lot of that is really going and displacing gray hydrogen in the refining industry to make green hydrogen. That's some of the opportunity. Second set of the opportunity there that you're seeing is really on sort of like sustainable aviation fuels, if you would, right, where they are really identifying a location where they can get access to low-cost power in the European market. So you can imagine, right, where you have a lot of hydro, where you can actually tap into some of the wind electricity with the low cost. That's where we're seeing some of this basic engineering design packet work.
Another big opportunity in places like Australia, where you're actually talking about big solar farms, low-cost solar, and this is really more of a green ammonia opportunity to impact export into the Asian market, right? So one of the good things here, Colin, is as a company that now has the largest PEM electrolyzer running in the Western world, we're actually able to also work with our customers on things we have learned, what challenges we went through, how we can help them with that.
And then we're looking at the customers win, who are the ones that actually have, as you rightfully pointed out, source of that power, the outlook for that offtake, whether it's going into the refining industry or going to the green ammonia market, going into the sustainable aviation fuel, you got to have the power, you got to have the land. You got to have the water. And that is what really gets you to that final investment decision, right? So -- and again, look, working hand-in-hand with them as a part of this [ FEED ] study really puts us in a very unique and a strong position to be able to collaborate with them and that's clearly the key criteria we use.
At the end of the day, Colin, it's really about selling value here for our customers, right. Bringing all that to the table and it's not just about price versus cost. Are we bringing value that allows them to have that attractive levelized cost of hydrogen whereby a very attractive green ammonia as well as opportunity to be able to play in the refining industry.
