Andrew Forrest and Mike Cannon-Brookes—Australia’s most vocal billionaires on climate change—have invested a further $210 million towards the world’s biggest intercontinental renewable power system. Sun Cable’s $30 billion Australia-Asia Power Link (AAPowerLink) project had already received nearly $50 million from Forrest and Cannon Brookes in 2019 through their respective investment firms, Squadron Energy and Grok Ventures. AAPowerLink is set to break numerous records once completed—including the longest high-voltage cable in the world, carrying 3 GW (gigawatts, or billion watts) through 4,200 km of undersea cabling from the Northern Territory to Singapore. This will be powered through 17 to 20 GW of solar—nearly matching Australia’s total solar capacity of 25 GW—across a 12,000 hectare area, 35 times the size of New York’s Central Park. To help maintain power at all periods, the project plans to build a whopping 36 to 42 GWh (gigawatt-hour) battery storage system, which at current prices alone …
