Tidal turbines harbor the potential to provide a natural, inexhaustible source of power, but have faced some regulatory ...

Submerged in about 40 meters (44 yards) of water off Scotland’s coast, a turbine has been spinning for more than six years to harness the power of ocean tides for electricity—a durability mark that ...

A world-first demonstration combining tidal power, battery storage, and hydrogen production has been completed at the European Marine Energy Centre (EMEC) in Orkney, Scotland.The demonstration ...

A European project, led by one of Scotland’s leading tidal developers, has demonstrated that the cost of tidal energy could potentially be reduced by as much as 40 percent, and has produced findings ...

At the bottom of Sequim Bay’s tidal channel, four-bladed turbines churn through the water. Critics have feared devices like this act as “underwater blenders,” chopping up everything from seals to ...

Underwater tidal turbines are gaining recognition as a viable renewable energy source, with energy companies and governments investing in research and development to improve their efficiency and ...
