Public Accounts committee  The process to come up with those cost assumptions was not NRCan's alone. We hired external consultants. We had lots of engagement with lots of experts across many of the provinces, if not all. That's how we came to this number.

Public Accounts committee  I'm sorry. Is there a question? I think we are updating those assumptions based on the new costs as they become clear, and we'll have that in March or early next year.

Public Accounts committee  Thanks. That's certainly a consideration. We have dedicated working groups, and through the hydrogen strategy we are specifically looking at standards, codes and precautions. As you said, safety is certainly number one for us.

Public Accounts committee  I believe so, yes.

Public Accounts committee  Thank you, Mr. Chair. That's a great question, and it's one that we're working on right now. We are currently updating the modelling that we did for the strategy, and we've worked very closely with colleagues at Environment and Climate Change Canada, the Canada Energy Regulator

Public Accounts committee  Yes, absolutely. As we think about the full potential of hydrogen in this case, we want to develop that in collaboration with people in the sector who are making investments, who are buying hydrogen and who are generating hydrogen. It's absolutely consistent with how we would, I

Public Accounts committee  Yes, absolutely. In the context of our clean fuels fund, for example, we have an awareness component to that. We provide a little bit of funding to promote that public awareness and confidence in fuels like hydrogen and other clean fuels.

Public Accounts committee  Natural Resources Canada is currently looking at the natural gas system to assess the impacts of blending hydrogen into the system. As you can imagine, it's a big network. It will take about three years to understand exactly how much blending can happen, what kinds of retrofits m

Public Accounts committee  I'm sorry, a higher...?

Public Accounts committee  I could get back to you on the specifics of the requirements. Typically, we know that, out east, they use some plastic-based materials. Those tend to be more resilient to hydrogen, but I would like to get back to you on that one, in particular.

Public Accounts committee  It's Atlantic Canada, yes.

Natural Resources committee  Thank you for your question. A total of 34,500 projects have been approved. Either the project is under construction or the department has notified the proponent that the project will be funded.

Environment committee  Thank you very much for the question. I would first like to point out that the Hydrogen Strategy for Canada is not a plan. It doesn't contain any programs. It is really a call to action, to consider the opportunities that hydrogen could create for the Canadian economy. In fact,

Environment committee  It was taken into account. We examined a whole range of technologies that are constantly evolving. For carbon capture, we analyzed all the processes. I could ask my colleague Mr. Hoskin to tell you more about it. However, I can tell you that the intensity of carbon emissions vari
