In response to TW’s comments on June 29, 2024.
As Australia and Singapore are far distant from each other:
Joint nuclear electricity programs
would not enjoy the advantages of continental Europe where large French
reactors can feed electricity into the German, Dutch and Belgian grids. Also
Sing and Aus are nuclear novices, each having no nuc electricity experience.
Better that Aus and Sing rely on countries with long power reactor experience, like South Korea, Canada or France to build nuclear reactors
in Aus and Sing.
The long range undersea power cable
proposed by some business interests would be high risk politically and
technically.
Politically an Aus-Sing cable totally relies on Aus and Sing having near permanent good relations with the country/waters the cable crosses ie. Indonesia. Heard of Konfrontasi when Indonesian President Sukarno's hostility impacted Sing and drew in "British Commonwealth" eg. Aus forces? https://en.wikipedia.org/wiki/Indonesia%E2%80%93Malaysia_confrontation Is it reasonable to expect Indonesia would have stable relations (or not demand too high a "cable rent" for crossing rights) with Aus and Sing - say for 60 to 100 years?
Also the cable could be cut
accidentally on purpose by the likes of Chinese Maritime Militia "trawlers".
Technically - long distance power
lines/cables have major downsides: "Long-distance power transmission can
lead to power loss, voltage drop, and environmental impacts.
...Another implication is voltage drop. As electricity travels along a transmission line, the voltage gradually decreases. This is due to the impedance of the line, which is a combination of its resistance and reactance." see https://www.tutorchase.com/answers/ib/physics/what-are-the-implications-of-long-distance-power-transmission
An alternate solution is Australia transforming its vast solar and windfarm potential into "Green" hydrogen and then shipping it, in liquid form, to Singapore. see https://www.dcceew.gov.au/energy/hydrogen
