Underwater Turbine Spins 6.5 Years Off Scotland's Coast, Proving Viability of Tidal Energy (apnews.com) 34
An underwater turbine has been spinning for more than six years "to harness the power of ocean tides for electricity," reports the Associated Press. The long-running turbine (off the coast of Scotland) has now proven the commercial viability of the technology:
Keeping a large, or grid-scale, turbine in place in the harsh sea environment that long is a record that helps pave the way for bigger tidal energy farms and makes it far more appealing to investors, according to the trade association Ocean Energy Europe. Tidal energy projects would be prohibitively expensive if the turbines had to be taken out of the water for maintenance every couple of years.
Tidal energy technologies are still in the early days of their commercial development, but their potential for generating clean energy is big. According to the National Renewable Energy Laboratory, marine energy, a term researchers use to refer to power generated from tides, currents, waves or temperature changes, is the world's largest untapped renewable energy resource.
This long-running tidal energy project off the coast of Scotland has four 1.5-megawatt turbines — enough to power 7,000 homes for a year, according to the article. But they plan to add 20 turbines in 2030 ("after needed upgrades to the electricity grid are finished"), and the site "could eventually hold as many as 130 turbines that are more powerful than those at the site today."
