Okay. Thank you very much. I can understand that this must be a very tricky area in which to make an accurate assessment, because a lot of these programs are not specific to one particular technology. Electricity could be biofuels or could be a lot of other low-carbon or net-zero fuels.
I actually asked this next question in my first round of questioning, but there was only about 20 seconds of time. Commissioner, I would like to give you the opportunity to really explain in a little more detail the best method for assessing the emissions-reduction potential for these emerging technologies, whether hydrogen or otherwise.
