Unfortunately Nuclear isn't quick or cheap or green, though I do think it will have to be an interim solution. I know that Rolls Royce, and so I assume others around the world, are looking at modular Nuclear reactors.
That will be interesting. I was a reactor controls officer on nuclear submarine back in the late 70's. To make the reactor small the uranium must be highly enriched. There is also a trick to how the uranium is placed or positioned in the reactor. Commercial reactors use uranium pellets. That isn't the case for navel reactors. Canada uses heavy water. That isn't cheap. So how small do you think the reactor will be?
BTW, the Fukushima reactor plant was a p!$$ poor design. Reactors can be designed so that the water goes through the reactor by natural convection so electric power is not needed below a certain power level.
When I was in college they built a nuclear plant down stream of Portland. It lasted for a few years and then it generated a leak between the primary and secondary cooling systems. This was probably due to poor chemistry that allowed corrosion of the steam generator pipes. This allowed the radioactive water from the primary system to contaminate the secondary steam/water system that turns the turbines. This makes any maintenance on the secondary system a radioactive hazard. The plant had to be shut down and the cooling towers are now gone.
I don't see it. While I think nuclear power can be safe, it must be handled with lots of care. More plants small nuke plants mean more operators that must be trained.
I am hoping that batteries will be better so storing wind and solar generated electricity is more practical.
There are lots of wind turbines along the Columbia river. There is a lot of wind in the Columbia river gorge which is renowned for wind surfing. There are also many damns on the Columbia River. Right now our problem is distributing the power. Our local bureaucrats want to do away with natural gas. I wonder if our grid can handle it.
The energy density of H2 is very low. H2 must be compressed much more than methane or propane to achieve the same energy density. H2 is relatively safe. The H2 levels must get to about 50% before it will explode. H2 will dissipate before the level gets too high unless it is in a confined area.
The sub could generate O2 by electrolysis. The problem we getting rid of the H2. It was pumped overboard. All that H2 wasted.
