It's a good question. We would need to build out a new hydrogen transportation infrastructure if we were to scale up two- or threefold at least. Right now, you can transport hydrogen in trucks at 250 to 500 bar up to 10,000 psi, but it's not all that cost-effective. I think that in the near term blending hydrogen with the existing natural gas stream up to ratios of 20% plus, may be possible.
Many jurisdictions are looking at dedicated hydrogen pipelines at some point. Fortis, in B.C., is looking at the potential to use a disused natural gas pipeline and re-sleeve it. Then it could accommodate up to 100% hydrogen. There are a number of storage and transportation options out there, but I think it's early days for Canada.
