Interconnectors set for key role in green energy systems

ENERGY transition discussions tend to be abuzz with clunky terms such as carbon sequestration, refuse derived fuels and distributed energy systems that green energy advocates hope will become common parlance as they become more widely used.

Less talked about but likely to become at least equally important are interconnectors, which are high-voltage cables that connect the power grids of different countries and allow for the trading of surplus electricity.
