Sure. Thank you for the question.
Issue number one is transportation infrastructure. Building out new transportation infrastructure is expensive, no matter what. I think what happened with the opportunity for natural gas transportation infrastructure was that the reality of that cost came to bear on the market advocates. Then oil prices started to drop and the comparative advantage wasn't as evident.
Issue number two is that when you're building out any new transportation infrastructure, you need to think about it in a broader context. If we're going to build natural gas refuelling infrastructure, we need to think about the four or five potential uses of it. We should have a coordinated plan to address that, not just for heavy duty trucking, but its application for remote communities, its application for rail, its application for marine. You need to think about the strategic location of refuelling centres in order to address those aspects and reduce the cost per unit, thereby making the opportunity more economically viable.
I think if we were to proceed on that basis going forward, we would see much more pickup of the opportunity for natural gas for transportation.
