Iberdrola SA Green Hydrogen Webinar Transcript

The following is excerpted from the question-and-answer section of the transcript.

Question: Jorge Guimarpes - JB Capital Markets, Sociedad de Valores, S.A., Research Division - Analyst : Firstly, on the -- if you take a step back on the electrolysis themselves. As of today, what is the -- how many -- for each kilogram of hydrogen, how many megawatt hours of electricity are needed. So what is the -- effectively the conversion ratios? And how do you expect it to evolve until 2030? And the second one would be, what is the lifetime of an electrolyzer? Is it comparable to a solar panel or, let's say, 10 years' time, one is to replace electrolyzer and spend the CapEx again? Millßn Garcfa-Tola Okay. Thank you very much for your question. There's some rule that it's easy to remember that you need 60 megawatts hour of electricity to produce 1 ton of hydrogen. That's the common figure right now. I think, I presume, and I'm sure that Alejandro -- not Alejandro, Agustfn will know better than me that there's some kind of improvement in this area. But as today, 60 megawatts hour per kilogram -- per ton. And your second question is how is -- how long do the electrolyzer exists. The main -- the bottleneck of an electrolyzer is a stack. The stack is some kind -- it's something that you can change during the whole life of the electrolyzer. So we are thinking, and we have been buying electrolyzer with 25 years of lifetime, but I'm sure that giving them the right maintenance and change in the stacks, it will last as much as they will be competitive. Diego Mor=n Martinez Thank you very much, Millßn. And I think that we're going for the last question, operator.
