Until SMR (small modular reactors) are available at Fly-in, fly-out camps and mine sites, they will use diesel or hydrogen. That will take at least a decade.

Alberta is going heavy into blue hydrogen. For them it's a win-win. They transition profit to natural gas (better than tar oil sands) and hydrogen is cheaper to produce, providing a base level of supply for heavy vehicles and the like.

You should ask yourself why we still spend money on anything else but this.

Using sunshine to create a gas that releases water when combusted is by a country mile better than anything else we have come up with. It's in fact hard to even imagine anything better!

If the petroleum industry uses its money to build infrastructure to handle hydrogen it'll the best thing they ever did, whatever their motivations are.

Because hydrogen is the future.
