We need to be doing both. Once the grid is fixed or close to it then we will need carbon capture to reverse the damage. It's either that or massive reforestation or using algae or something (liquid trees anyone?).
Pure reactionary xenophobia. Chinese thorium reactors are cutting edge, and we're adding degree points to the global average by not adopting it ASAP.
If they own the plant they could theoretically sabotage it. Would they in practice? No idea but so long as the USA believes they might they won't use Chinese technology.
Neither the USA or China are good regimes. To be honest I want to see them both either broken or re-formed.
Westinghouse aren't the only people in the USA doing nuclear research afaik. I believe the DOE national laboratory does research on fusion for example. There are private companies like NuScale also working on fission designs in the USA.
If you were familiar with the technology, you'd understand why it has failed to come to market for so long. You need enormous subsidies to sell vehicles and even then you cannot efficiently produce "Green H2"
Halting emissions is the most efficient method of reducing total emissions. Capture is extraordinarily expensive and inefficient, particularly when you're still using carbon-based infrastructure to power compressors.
This isn't a "right now" issue. Its been an ongoing problem since the '90s. And yes, throwing 10x your investment in a working solution on a speculative technology for 35 years running is a bad idea.
Now you sound like the people advocating against renewables.
The O&G industry has been the primary promoter of fuel cell technology. They never deliver and they've had far more money and time to work on this problem than the nascent solar and wind industries.
