Europe could ride the wave of Ocean Energy


Up to 20 million homes in Europe could be powered by clean renewable energy from the sea, according to ocean energy expert Teresa Pontes of Portugal, who was speaking at the EurOCEAN marine science and policy event in Galway today (12th May). She estimated that, by harnessing energy from waves and marine currents, Europe would produce around 200 TerraWatt (200 million megawatt) hours per year of electrical power.

“The oceans contain a huge energy resource with different origins,” said Ms. Teresa Pontes. “The most developed conversion technologies are for tidal energy, thermal energy, marine currents and ocean waves. The last two technologies are those which have received most attention in that last fifteen years, as they show the best prospects of becoming competitive in the short to medium term.”

Wave and marine current energy generation are generally considered to be environmentally benign, with the only impacts being visual intrusion and possibly noise from air turbines on shoreline wave power plants. For offshore ocean energy plants the only conflicts could come from shipping, navigation and fishing and most of these conflicts could be minimised and, in some cases, eliminated at the planning stage.

“Europe is characterised by particularly high ocean energy, with the highest offshore power levels off Ireland and Scotland,” added M. Teresa Pontes. Going eastwards and southwards, energy levels drop from the 70 kiloWatts per hour off Ireland and Scotland to 30 kiloWatts per hour off Norway and the southern archipelagos of Madeira and the Canaries.

The EurOCEAN event continues today and tomorrow in Galway with over 500 participants from all over Europe. One of the major themes of the event is ‘Communicating Marine Science’, which was used as a keynote address by leading journalist Mr. Clive Cookson – Science Editor of the Financial Times. “Scientists are coming to realise how important it is to communicate their work to the public through the media and to engage with the public on controversial issues,” said Mr Cookson.

The EurOCEAN Conference concludes tomorrow with an address by Mr. Dermot Ahern TD., Minister for Communications, Marine and Natural Resources. Rapporteurs from six parallel and plenary sessions will highlight future challenges and priorities identified during the three day Conference at the Radisson Hotel, Galway.

EurOCEAN 2004 is a European Presidency event sponsored by the European Commission, the Marine Institute, and the European Science Foundation Marine Board (ESF-MB).

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
