"so it was just a case,of cost effectiveness,we went for the cheap,available alternative."
And we will again. The cost of change is enormous, and so is the amount of resources and energy required to build it all. Which ever way it goes, we will be paying the cost through our bills for years to come. eg Price of elec was not high enough to attract a single bidder for a UK offshore wind farm contract auction the other day.
Ironically coal, gas and oil could live on if CO2 scrubbers arrive soon. US & UK Govts are investing heavily in research. Many countries have access to these resources already, and all to some extent, have the existing infrastructure. It is a low cost solution and is relatively quick to implement. It would allow developing countries to build their way in to a carbon free future as China has done and Saudi is going to do.
It is also ironic that China is the biggest user of coal in the world, but has installed more wind, solar and batteries then anyone else. The Saudi's are using their vast oil wealth to build large scale solar and batteries too. But these are two rich men whose country's have large vanadium resources as a by-product. And probably the only two countries that might meet their emission targets on time.
The voting/tax paying people of the world will have to share the costs where they are, and you can only milk a cow so much. So I think its going to take a decade or two for the West to achieve the same as these guys, or make the changes needed to curb emissions fast enough to stop the 2 degrees C rise. Germany has already caved and delayed its gas boiler ban, UK will too. EV's next. Also why I dont see the same rate of take up of VFRBs in the West before it is eclipsed by a cheaper alternative or change of direction.
I'm just musing, I'll say no more on VRFBs or heat-pumps. The future rarely turns out as we see it, there's always a curve ball. But it is 'all about the money'.
