Considerable investment is still needed to develop the technology and establish business models for those energies. At the moment, whether those business models are going to work is rather uncertain because they have a lot of holes. The revenue generated for the producing country won't be as significant, that's for sure. The profit margins aren't comparable to those in the oil and gas sector, where costs are relatively low in relation to prices in the global marketplace.
There's a lot of assessment work to be done to figure out the right approach and the technology needed, as well as to build the infrastructure. For instance, nothing equivalent to an LNG carrier exists to transport hydrogen by sea. As far as those markets are concerned, we are already seeing a considerable need to develop the intelligence and business models. At that point, Canada could play a role in doing some of the work.
