Based on the reading I've done, I would tell you that blue hydrogen isn't something we can bank on. We would have to look at green hydrogen. Western Canada has great potential, for both wind and solar power. Using these renewables, we could produce hydrogen to be used locally in Canada or exported. This would be the most promising avenue.
We mustn't forget that producing hydrogen from methane or oil sands yields a very low energy return on investment. In contrast, producing energy from high-power wind installations currently yields an EROI of 70 to 1. In other words, using one unit of energy yields an energy gain of 70 kilowatts, a much more attractive return. We should be focusing on these streams instead.
