UK officials are underestimating the vast energy potential of marine tides, a renewable and reliable energy source that could meet 20 percent of the nation’s electricity needs, according to a new report.

Writing in the journal Philosophical Transactions of the Royal Society A, researchers explain that while the process of exploiting tidal energy remains (more…)

Ocean Renewable Power Company (ORPC) is Maine company that develops ocean and river power systems.

According to this NRDC blog post, ORPC’s Cobscook Bay tidal energy project in the Bay of Fundy in Maine is the first in the U.S. to receive a FERC license, include a power purchase agreement, and install and (more…)

Ecofys is Dutch renewable energy and climate policy consultancy that has developed a Wave Rotor tidal energy device.

IHC Merwede, a Dutch company that focuses on design and construction solutions for the maritime sector, recently acquired the Wave Rotor technology.

The Wave Rotor technology enables IHC Merwede to (more…)

The Heslin Rothenberg firm’s Clean Energy Patent Growth Index (CEPGI) 2011 Year in Review was published earlier this month.

The 2011 roundup found that granted green patents were at an all time high of 2331 for last year, a rise of 450 patents, or 24%, over 2010.

Always an interesting read, the CEPGI is quarterly (more…)

The Federal Energy Regulatory Commission (FERC) recently issued its first pilot project license for a tidal energy project located in New York City’s East River. The project is owned by Verdant Power and is known as the Roosevelt Island Tidal Energy (RITE) Project. The project’s capacity is 1,050-kilowatts and uses the East River’s natural tidal currents to generate (more…)

According to a new study by the Carbon Trust up to 240 GW of capacity of marine energy could be installed worldwide by 2050. Out of these, 75 percent could be coming from wave, and the remainder by tidal energy.

The total market for both wave and tidal energies (more…)

Tidal energy proponents are optimistic that the French government strategy of “investments in the future” could by the end of the summer lead to governmental support for the France Ocean Energies technological platform supported by the Institut français de recherche pour l’exploitation de la (more…)

Nautricity is a UK company that develops tidal energy technology. Its CoRMaT tidal turbine, a 500kw device in its largest form, will be installed and tested in the Thames River alongside a former Royal Navy sloop called the HQS Wellington (see Clean Technica article).

The CoRMaT turbine is the subject of at least one (more…)

Tidal power, also called tidal energy, is a form of hydropower that converts the energy of tides into electricity or other useful forms of power. The first large-scale tidal power plant (the Rance Tidal Power Station) started operation in 1966. Harnessing the power of ocean tides has long been imagined, but countries are only now putting it into practice. A demonstration (more…)
