Absolutely. I can't resist. Thank you for the question.
The areas we see or the areas we have put investments in are in situ upgrading, again focusing in on some areas where you can create a big impact. One example would be in situ upgrading to avoid having to add a whole bunch of diluent. What that does is allow you to ship your oil to multiple refineries. It creates a bigger market. That's one technology that's well along, and well developed, and coming through our process.
The other side of it is providing other ways of producing hydrogen for hydrocracking. All the work and all the investment that has gone into the hydrogen economy up until now is shifting direction for it to say how can we produce hydrogen more efficiently to apply to the oil sands. That's something we've started to do.
