concept what is wave energy
Concept – What is wave energy?
  • Waves are formed by the wind. The stronger and longer distance of wind generates larger waves and energy.
  • Wave energy is a concentrated form of solar energy.
  • The greatest amount of energy is available in deeper well-exposed waters offshore.
  • The capacity to harness the incident energy is larger than that of wind or solar systems. (refer Fig.1)

  • Devices take energy out of the motion of the water near surface and convert the action into movements that power generators to produce electricity.

market status
Market Status
  • The primary market for wave energy is electricity generation.
  • There are opportunities to produce mechanical energy for the desalination of, or mineral extraction from, sea water.
  • While still new technologies with high cost, significant improvements are predicted generating costs of devices. (5p/kWh or less at 8% discount rate)
  • Economically competitive in the market of isolated communities that are not connected to the grid.
market status the u k
Market Status- the U.K.
  • The U.K. is situated at the end of long stormy fetch of the Atlantic, where characterised by high wave energy.
  • Work on wave energy within the U.K. began in the early 1970s.
  • Department of Trade and Industry (DTI) has supported R&D on smaller devices which are more economic.

Areas Studied for UK for wave energy resource assessment

potentials
Potentials
  • The wave energy devices are less environmentally degrading than others.
  • Limit potential for chemical
  • pollution
  • Little visual impact
  • Low noise generation
  • Less influence the coastal
  • environment
  • Less CO2 emission than
  • others
projection technologies
Projection- Technologies
  • Multiple concepts such as wind-wave, wind-tidal, or wave-tidal system may emerge as ocean energy exploration.

  • UK targets of 20% of electricity from renewable energy sources by 2020.
  • A large share of the European deployment of marine energy devices by 2020 could occur in the UK.
  • Beyond 2020 the industry would turn to long-term off shore operation in the UK.
  • Further improvement of generating costs is expected as the same way as wind turbines.
