tidal energy
It’s an ironic reality that, to develop renewable energy, you must use at least some non-renewable resources … things like steel and rare-earth metals. But a tidal power company in Norway is hoping to make its technologies a little less ironic. Hydra Tidal plans to forgo the steel and composite

France-based Alstom Hydro has entered the ocean energy market by signing a licencing cooperation agreement with Clean Current Power Systems, a Canadian firm that specialises in the design and testing of tidal energy technology. The International Energy Agency estimates that, worldwide tidal stream sites could generate as much as 100

Two British engineers have developed what they say is a breakthrough design that could, within five years, begin to generate substantial amounts of cheap electricity from deepwater tidal flows. UK-based TidalStream reported this week that its turbine platform design — code-named Triton — successfully underwent validation testing at the deep-water test basin

The Government’s shortlist of tidal power schemes for the Severn Estuary is “seriously flawed,” and should be scrapped, according to a review commissioned by an alliance of environmental organisations. The alliance includes the Royal Society for the Protection of Birds (RSPB), WWF, WWT, National Trust, and the Wye and

After months of work, UK-based Pulse Tidal’s “Pulse Stream 100” tidal generator is now fully assembled and undergoing commissioning and testing in the Humber Estuary near Immingham. The firm says the device is the “world’s first grid-connected shallow water tidal stream generator.” The Pulse Stream 100 operates in

Estuary barrages in the North West could provide as much as 5 percent of the UK’s electricity needs, according to engineers at the University of Liverpool. The engineers studied the tidal energy potential of barrages across the Solway Firth, Morecambe Bay and the Mersey and Dee estuaries. The most
hydrokinetic energy
Forget massive and costly hydroelectric dams: the future of water-based energy could lie, literally, below the surface in the form of hydrokinetic turbines. Basically underwater turbines that generate energy via waves, tides and currents instead of wind, these hydrokinetic devices are enjoying their first commercial test run in the US,
