While connecting both coasts seems like a good idea on paper, when you do the numbers it doesn't stack up.

That idea was floated to connect gas across the country many years ago. lt never eventuated because shipping is much cheaper.

The youtube channel ' Engineering with Rosie ' talked about it in one of her videos. l'll post it if l can find it. She used current data about HVDC .

Basically it's just a numbers game. The cost of transmission vs the cost of energy storage at each end.
