Yes, thank you.
Definitely, without a question, the cost to produce clean hydrogen today—and I'll use the term “clean hydrogen”—is higher than the cost to produce grey hydrogen. However, that is in the control of government. That's what policies such as the price on carbon and the low-carbon fuel standard are closing, because they're starting to put a price on carbon emissions. That means clean alternatives can become economically viable. It's a necessary thing. You have to have some mechanism for putting a price on CO2 emissions to make the clean alternatives cost-competitive.
The cost of those clean alternatives is dropping rapidly, with scale in particular, and scale is really what it takes. It leads to conversations about hubs or conversations about getting projects under way to get that scale.
