From Fast Company’s Co.Exist series, check out 8 of the latest advances in ocean-powered generators. Most of the devices are being developed in Scotland, which is apparently a world leader in marine energy investment – who knew? They’re all well beyond the design stage, with working prototypes being deployed and tested in the rough waters of the North Sea.
They cover the full spectrum of ocean-generated power, creating electricity out of everything from tides to waves to currents. There are a few hurdles, such as figuring out how to efficiently transfer the power to land, and how to administer maintenance. While it’s estimated these devices won’t be operating at a commercial scale for another 2 to 3 years, they could supply as much as 10% of the UK’s power needs once online (that’s 75,000 megawatts for those of you keeping score at home). Carbon-free and eternally renewable – how’s that for future power?
