In terms of the clean hydrogen investment tax credit, I think you'll notice that the credit is based on the carbon intensity of the hydrogen produced. Essentially, that looks at the amount of emissions from the beginning of the process, or what is called “cradle to gate”. It's essentially the point where the hydrogen leaves the factory. It's the amount of emissions through that entire production process that establishes the credit rate. Of course, the cleaner the hydrogen—i.e., the lower the emissions—the higher the credit rate will be.
To your question, in order to reach a level of carbon intensity that allows you to access the credit or to access it at a higher rate, the carbon capture technology has to be effective. It has to be capturing a very high proportion of the carbon and storing it through approved storage mechanisms.
Essentially, that is what allows you to ensure that the carbon capture technology is working properly. It's stored either underground or in concrete, as in the case for the CCUS tax credit. If that's not effective, then you essentially won't achieve the level of carbon capture intensity that is needed to access the credit.
I think that answers the question.
