Wave & Tidal

pumped storage

This is an out-of-the-box idea for a massive energy storage scheme, the largest potential pumped storage opportunity anywhere in North America: the Lake Erie/Lake Ontario System.[read more]

ocean thermal energy conversion

With Ocean Thermal Energy Conversion deployment, the navy can become energy self-sufficient in its own domain and can be relieved of a heavy burden in the Middle East; a win for the navy, a win for the planet.[read more]

sea-level rise

One of the most important and threatening risks of climate change is sea-level rise. The mechanisms are well understood, and the direction of changes in sea-level is highly certain.[read more]

The small French island of Mont Saint-Michel, a UNESCO World Heritage site, is famous for its fast and forcefully rising tides. The famous writer Victor Hugo once claimed them to be as fast as galloping horses. Tidal energy is all about capturing this energy of the sea. While large tidal projects have been proposed for centuries, actual...[read more]

While going for a stroll along the seaside, many enjoy the magnificent sight of waves hitting the shore. Few will realize the unique opportunity to visualize the enormous amount of energy that waves carry. Is this the next big source of renewable energy?[read more]

Energy transition is not just an imperative: it’s a certainty. But while it’s certain that we’ll continue to transition towards a new energy mix, far less certain are the nature of this mix and the speed of our transition. Also uncertain, though certain to be profound, are the impacts of this transition on human societies and the economies and earth systems that sustain them.[read more]

The ocean is a tremendous bank of energy. Covering more than two-thirds of our planet, the amount of energy embodied in the ocean’s tides, currents, and waves, not to mention temperature and salinity gradients, could power the world—if we were able to commercialize the technology to harness its renewable power.While technologies...[read more]

Surfers spend half their time on the water sitting upright on their boards, scanning the horizon for the next suitable wave. The reason of course is that a wave’s size and power is going to tell you a lot about how good a ride you’re likely to have.Well, the same is true of wave energy capture technology. Put simply, some waves are...[read more]

Israel-based wave power designer and manufacturer Eco Wave Power (EWP) has completed the first open water phase of testing for its new wave energy device. The company said it successfully installed a medium-scale wave energy power plant in the Black Sea during April.The latest phase of testing follows on from the initial...[read more]

The British government has a launched a £20 million ($32 million) scheme to fund projects for groups of wave machines.The funding money is available for up to two pre-commercial projects and will allow the development of single device prototypes into a cluster of devices. The successful bids will test the operation of their...[read 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...[read more]

GreenBang reports that Siemens its expanding its presence in the ocean energy market - In marine current energy, Siemens wants to be 800-lb gorilla.There’s a lot of energy in the world’s oceans, and Siemens wants to play a big part in developing that power for our use.The Germany-based technology giant announced today that it’s taken on...[read more]

 While reading “Rising tide: Company unveils plans for cutting-edge turbine to be deployed next spring” it spurred some interest on how tidal power continues to slowly move forward. Ocean Renewable Power Company (ORPC) offered an open house to everyone in the Eastport Maine community(1). ORPC’s open house was on their 35-ton...[read more]

A recent study performed by the Indian government shows the country has an estimated 8,000 megawatts of tidal energy potential. According to the assessment, the majority of this potential lies in the Gulf of Cambay where 7,000 megawatts of energy could be reportedly harnessed.  The report also indicates two other areas could be...[read more]
