Yes. No, it’s a great question, Mark. So, look, we, in the context of Sun 5, are actively considering what the CCS or CCUS kind of strategy on that might be in the future. And it’s expensive. It is -- that would be a unit that would generate, call it, 2, 2.5 megatons a year of CO2. And in today’s dollars, kind of the cost of putting CCS on a facility like that that would capture, call it, 90% of the emissions coming out of that, would be easily in the $800 million range, possibly even more. So, it’s not much different, Mark, than the actual cost of the repowering, of the unit that’s there. So, we are actively looking at it. We’re in discussions with the government. I think, there’s been some constructive proposals that came out of the budget, certainly from a federal government perspective, and there’s more work to do to develop it. But, I think there’s a recognition, both by the industry and by government that achieving our goals is going to require probably some assistance to get some of these kinds of investments done in a way that just makes sense economically going forward. You had a couple of other points there. I mean, from a -- in terms of the urgency for that, Sun 5 will be a pretty efficient facility. So, even though we’re seeing an increase in carbon pricing going forward, the sort of incremental annual increase in cost is relatively modest, kind of in that $2 to $3 a year incremental cost from a carbon perspective. So, it really bites, I think, 5, 6 years out where you start seeing carbon pricing approaching that $100 range, which might then begin to make some of these kind of technologies more economic. The final thing that I’d say, you mentioned hydrogen. We are looking at hydrogen and assessing it. It’s pretty expensive. Candidly, Mark, I mean, many times more expensive than natural gas is right now. And there’s a couple of other challenges associated with it. I mean, one, there’s a lot of infrastructure build-out that would have to take place to make sure, A, that we’ve got the supply and it can be delivered to the facilities to run them. But probably more importantly, at least in the foreseeable term, the existing infrastructure that’s in place isn’t really all that well suited to blending it or burning it. And the challenge you have is even if you mix it, which we think we can probably do and it wouldn’t cost a ton more from a capital perspective, there isn’t a linear relationship between your emissions reductions and the hydrogen that you burn. So, for example, if you burn 30% hydrogen in the fuel mix, you won’t get a 30% reduction in emissions. The emissions reductions might be half that. It’s only when you get to kind of 80%, 90% levels of hydrogen kind of burn that you sort of capture equivalent levels of CO2 emissions. So, it’s a bit of a long answer, but I just want to give you a flavor of the way our company is looking at it, and we’re looking at the technology. And certainly, we’re looking at companies we could partner with to move it forward. I think it’s going to require a collaborative effort.
