Public Accounts committee  But in a certain sense, hydrogen is hydrogen. There are current applications once one has created the hydrogen that exists right now, and that includes transportation. You're seeing applications in trains, for instance.

Public Accounts committee  I think the question becomes the manner in which you are generating the energy. One possibility that is being considered very actively right now is using wind on the east coast, where you use wind to generate the electricity that then converts the water into hydrogen. That—

Public Accounts committee  We have active arrangements right now. We have an arrangement with the Germans, which is a structured conversation precisely to determine what that market will look like, and—

Public Accounts committee  Your conversation continues on LNG as well. A number of drivers would lead the Germans to be interested in the conversations we are having right now. One of them is the fact that there is an energy challenge in Europe right now as a result of what's going on in Ukraine. Multiple

Public Accounts committee  The other piece of it is that they are looking at alternative energies of a number of different varieties in order to meet their climate objectives. Hydrogen is at least one potential source there, as—

Public Accounts committee  The focus is on achieving the lowest carbon concentration possible with respect to the generation of hydrogen. We've framed our approach not so much on colours as on basically carbon intensity. That is a technological question, as to how you reduce the carbon intensity of the fue

Public Accounts committee  We have taken the recommendations of the commissioner, but, as I said at the outset, the exercises that we were engaged in were different exercises. Natural Resources Canada had been engaged in what we have termed a “call to action”, because it was really intended to show the pot

Public Accounts committee  I'm not aware of any specific studies of costing of infrastructure, but I'll look to my colleague. No, we have not.

Public Accounts committee  Perhaps I could answer—

Public Accounts committee  I think there are a couple of issues here. There is currently the potential to move hydrogen, to some degree. You can blend hydrogen with other gases and it can be moved through existing infrastructure at relatively low ratios. That is a possibility right now. Other possibiliti

Public Accounts committee  I would describe it as a work in progress.

Public Accounts committee  I will defer to my colleague on certain details, but the blending levels.... I think this is one area where we continue to study what the effect of higher concentrations of hydrogen would be on existing infrastructure. That's where you get into questions around retrofits, as well

Public Accounts committee  That's my [Technical difficulty—Editor].

Public Accounts committee  The costs vary between the feedstocks, but one thing you're seeing through some of the international investments is the technology continuing to evolve, so —

Public Accounts committee  I'm sorry. Was that a question for me?
