2) Marine Energy?
• Energy sources:
1. Tidal energy: dam (French: barrage)
2. Tidal energy: currents
3. Wave energy
4. Osmotical energy: salt/fresh water gradients
5. Thermal energy: hot/cold water gradients

2) Wave – Tidal - WindWaves Tidal Current Wind
Meteo Dependant
Time shift of the wind
(difference sea and
swell waves!)
Almost independent, but
highly cyclical (ebb-flood
// spring – neap tide)
Depending on local
wind only
Energy density High, less variable
than wind
high Moderate (5MW for a
diameter of 126m)
Visual hindrance Limited None (except marker
buoys or access
structures)
Yes
Challenges - Efficiency
- ‘Survivability’
- Grid
- Efficiency
- Reliability in marine
environment (salt,
biolfouling)
- Grid
- Capacity factor
- Grid connection
- Reinforcement,
logistics.
Complementary and synergetic possibilities need to be researched!

horizontal axis turbine14
FOD Economy IA day IEA-OES: -6/12/2011 – Pieter Mathys
3) Tidal Energy Converters: TEC
• Different types, but not as diverse as Wave
Energy Convertors.
15
FOD Economy IA day IEA-OES: -6/12/2011 – Pieter Mathys
3) WEC: FlanSea
16
Aim of FlanSea
- Research about all aspects and components of a wave energy convertor…
- Which will lead to a robust and efficient Wave Energy Convertor concept…
- Suited for a moderate wave climate
- Funded by IWT (2.4 mio €) and private partners (seenext slide)

FOD Economy IA day IEA-OES: -6/12/2011 – Pieter Mathys
4bis) Belgium support policy
• Tradable Green Certificates
– Support mechanism
– Guarantee of origin
– Certificate obligation
�Market transparancy, sometimes difficult administration
(cfr recent VREG report on tariff for renewable energy)
�Independent of the electrity produced
• Both on federal and Flemish level
– But limited harmonization…

4bis) Belgium: so what is it?
• Flemish support?
– North Sea from low water
line? � Federal!
– <70 kV: Flemish, > 70 kV
Federal
• (Nota Di Rupo July: difference
transmission-distribution vs 70
kV)
• Federal support?
– What is ‘hydro’energy? Not
defined!33
FOD Economy IA day IEA-OES: -6/12/2011 – Pieter Mathys
4bis) Belgium: so what is it?
• Flemish support?
– Unclear, most likely not
applicable (personal
communication VREG)
• Federal support?
– Unclear, no clear view on
‘hydropower’ definition
• Best case: 90 €/MWh, 10 yr
• Mid case: 50 €/MWh, 10 yr
• Worst case: 20 €/MWh, 10 yr34

5) Future role / participation Belgium
• Key moment: industry is at stall speed
• Should Belgium form a wave/tidal energy
cluster? Open debate
– University representation has limitations � only
travel expenses, no personel budget, makes any
(pro-) active or long term committment impossible
– Some options:
• Sector Federation: Agoria AREC?
• Dutch Example: EWA: Nederlandse Vereniging voor
Energie uit Water 36
FOD Economy IA day IEA-OES: -6/12/2011 – Pieter Mathys
5) Future role: EWA example?

Conclusion
• Marine industry is at stall speed
– Belgium future role?
– Please: clarify and adapt the support system: no
technology can be commercially implemented
with the current policy
• Wave-tidal energy sector?
– EWA example the Netherlands
