Not holding my breath. but it is possible
If China starts making green grid technology for the rest of the world then it could result it being used in China too. Once they start producing something in quantity it will not only be sold cheaply to other countries but may also be used locally. Not because it is green but because it is cheap and available.
Much better that importing dirty coal from us crazy Aussies who are madly digging up our back yard and selling it to the cheapest bidder.
