Researchers at the Group of R&D GITERM at the Higher Technical School of Naval Architecture and Ocean Engineering of the Universidad Politécnica de Madrid working with the Astilleros Balenciaga company and the Fundación Centro Tecnológico Soermar have built and tested a prototype of a device to harness energy from ocean currents that is able to [...]

Oxford researchers have developed a new tidal turbine that has the potential to harness tidal energy more efficiently and cheaply.  Now the technology has been licensed to new company, Kepler Energy Limited, formed to develop the tidal turbine and to build the device simply, more robust and more scaleable than current commercial designs. The turbine [...]

Reading Maria Surma Manka’s Maria Energia site tipped me to an interesting source of chemical energy that is abundant and close to many major metropolitan areas. Currently called osmotic energy it’s really a use of the salinity gradient energy that becomes available when fresh water contacts with seawater. The osmosis name comes from the membrane [...]

I’m not real certain just what the process is for the Crown Estates in the UK about leasing tidal areas, but it seems to be competitive for at least two companies to battle to have their ocean current designs installed at Pentland Firth, off the coast of Scotland. Pentland Firth is in the UK’s far [...]
