How far is it from Aus to Singapore? Just wondering how long the submarine HVDC would have to be?  Given that the idea for an HVDC from Iceland to Scotland is considered too costly for its 1000km length to be worthwhile...

According to the Guardian article the cable run will be 3,800km  Shocked

There's that new ultra HVDC line in China which is 3300km long, which is rated at 12GW capacity (1.1 million volts DC!) so I guess it's not completely out of the question - but that's not under water...

Have you seen the Pylons. they are massive. Not made of steel angle section, but flanged steel tube. Also the Hex bundle conductors look impressive, but the conductor cross sections look smaller than the old Quad bundle ACSR conductors used on UK L6 400kV towers.

Major problem with bundled solid insulated DC HV cables, especially those insulated with XLPE is water treeing within the insulation. Also dielectric recovery, when the cable is de-energised, difficult to safely discharge the stored charge within the cable.

Once we have RE hydrogen sorted then there is no end to where this might lead. Recently there was an article on how Aussies had cracked a cheaper way of making Ammonia to transport to Asia. Sea shipment Aus to Asia would be cheap and not reliant on a 100% reliable leccy cable.
