THE BACKGROUND

• Portugal has a good wave energy resource
• (25-30 kW/m in 50-100m deep water)

• Relatively narrow continental shelf
• (50m-deep-water line 6-12 km from shore)

• Most of the population near the coast

• Electrical grid available for connection near
  the coast

• Harbour and shipyard facilities

• Tradition in coastal and harbour engineering
• (although not in offshore engineering)

• Dedicated legislation special tariff for wave
  energy

RD in Wave Energy at IST

• Interest in Portugal started in mid-1970s
• Work started at IST about 1977 (INETI 1983, WEC
  2003)

• Involvement in pilot plant development
  monitoring
• Pico, Azores (OWC plant),1993-
• Limpet, Islay, Scotland (OWC plant), 1995-2000
• AWS (submerged device), 1998-
• Foz do Douro, Porto (OWC in breakwater), 2005-

• AquaBuoy, (floating device), 2006-
• Martifer SA (floating device), 2006-
• Cores (floating OWC), 2008-

9
The European context

• 1991 The European Commission approved the
  inclusion of wave energy in the JOULE RD
  programme on Energy (main drive provided by
  Portugal, Ireland and Denmark).

• Participation of IST in European projects, since
  1992
• 14 projects, of which 5 with overall coordination
  of IST

Scientific Output in Wave Energy from IST
45 papers in international archival journals
(since 1984) 140 papers in international
conferences (since 1980) 10 completed Ph.D.
theses (since 1985)
