I believe you are 80% correct, but unfortunately it goes so much further than that. The market is not the be all and end all of it.
Often the very reason why one thing is more widely found on the market than another thing is simply history. When you're a power utility in South Africa for example it's a lot easier to build a coal fired power station than a PV farm not simply because there's lots of coal here (sunshine is also in abundance), but because we've been building coal fired power stations here for 100 years and PV farms for only 10. You want a new coal fired power station? Sure no problem! We've got all the drawings, all the components and all the expertise you need! There are thousands of engineers and technicians with decades of experience all standing in line with their CV's. There are factories and constructions companies all over the place that will happily get things off to a flying start. A new PV farm will not be so easy yet, a lot has to be done from scratch and procurement is a bit harder.
It does not necessarily mean coal-fired is a better technology though.
Could it be a similar story between batteries and other energy storage technologies for example?
