ERI
● Predict environmental impacts of wave & tidal devices
● Address key roadblocks in developing the UK marine renewables sector
Building capacity in the region
● Provide next generation of leaders in marine energy research
● Provide industry a dynamic & enduring R&D base in the locality
SuperGen marine
Strategic Research Development Grant
Offshore Renewable Energy Conversion platforms
– Coordination Action (OREC-CA)
MaREE: A capacity building project
● Builds on: Existing expertise in marine & environmental sciences
Current activity and partnerships
Unique resource potential of the region
● Focus Environmental issues related to marine renewable energy
+ the socio-economic aspects
● Aims Establish academic leadership in the H&Is in a sector that
contributes to Government’s renewable energy targets
To develop a sustainable programme of applied and
fundamental research (+ associated KE and commercial
activity)
- Underpinned by strategic partnerships

Matching data on survey tracks (above) to
low-resolution model data (below)
Underway ADCP surveys
• Current strengths can vary over distances
of only 100 metres
• Flood and Ebb Streams can be
asymmetric
• In Strength
• In Position
• In Direction
• “Bi-directionality” of tidal currents is rare
• Asymmetry
• Tidal ellipses
• Eddies
• Vertical shear is mainly (but not always)
restricted to near the sea bottom
Detailed Characteristics of the Tidal Stream

How are the hydrodynamics altered
by introducing energy extraction?
If we introduce a tidal fence, significant
current anomalies are inevitably
introduced
Large anomalies result from GigaWatt-
scale extraction, with diminishing returns
Currents → Sedimentation Dynamics
→ Habitat → Ecology
3 Dimensional Flow
Wave Climate
• Offshore wave climate can
be effectively measured by
satellite altimetry
• At sites such as Pentland
Firth, there is a complex
interaction of waves with
bathymetry and currents
•Validated wave model
output is essential data for
exposed tidal energy sites
such as the Pentland Firth
Wave Modelling
Simple case of a uniform 1 metre sea propagating from the western boundary
Remote Sensing Methods
Radial Velocity by SAR ATI (X-SAR /
SRTM). N.B. one colour cycle equates
to a difference in velocity component
of 4m/s. From Runge et al. (2004)
“RASCAL PF”; Courtesy Lucy
Wyatt and Jon Side
N.B. Waves also!
Coastal HF Radar SAR Along Track
Interferometry
Conclusions
1) The Pentland Firth is a genuine resource, but is
also a valued and challenging environment
2) ERI emphasises observation and development of
VALIDATED models
3) Characteristics need to be measured and modelled
to scales of 10s of metres
4) ADCP survey methods (and fixed bottom-mounted
ADCP) are effective but costly and time-consuming
5) Currents and waves should also be measured by
remote sensing methods to extend spatial
coverage.

Physical Characteristics Of A Real Tidal Energy Resource [David Woolf]

  • 1. The Physical Characteristics of a Real Tidal Energy Resource David Woolf ERI, North Highland College,Thurso UHI Millennium Institute David.Woolf@thurso.uhi.ac.uk
  • 3. ● Predict environmental impacts of wave & tidal devices ● Address key roadblocks in developing the UK marine renewables sector Building capacity in the region ● Provide next generation of leaders in marine energy research ● Provide industry a dynamic & enduring R&D base in the locality SuperGen marine Strategic Research Development Grant Offshore Renewable Energy Conversion platforms – Coordination Action (OREC-CA)
  • 4. MaREE: A capacity building project ● Builds on: Existing expertise in marine & environmental sciences Current activity and partnerships Unique resource potential of the region ● Focus Environmental issues related to marine renewable energy + the socio-economic aspects ● Aims Establish academic leadership in the H&Is in a sector that contributes to Government’s renewable energy targets To develop a sustainable programme of applied and fundamental research (+ associated KE and commercial activity) - Underpinned by strategic partnerships
  • 5. Resources and risks Research staff: Dr. Peter Bowyer Dr. Lonneke Godijn-Murphy Dr. Tariq El-Geziry * Technicians: Soeren Hoejlund Yen-Fu Chen Dr. Jason McIlvenny ● Tidal resource assessment / Wave climate assessment ● Modelling device-environment physical interaction ● Weather windowing ● Satellite, radar, acoustics and buoys data, GIS /modelling Dr. David Woolf Theme lead PhD researchers: M. Easton - An integrated modelling framework for EIA of large-scale arrays J. Dufaur *- Meteorological forcing of current & sea level anomalies in Pentland Firth G. Marchi *- Tidal races in the Pentland Firth as an obstacle to tidal stream energy development
  • 6. Outline of Tidal Stream Research • Analysis and GIS Mapping of Low Resolution Model (POLPRED Orkney Model) – Lora Jane Dillon, 2006-7 • Underway ADCP Surveys – Lonneke Goddijn-Murphy, 2009 • High Resolution Modelling – Matt Easton, 2009 - (see also PG presentation) – Peter Bowyer, 2010 - • Remote Sensing Methods
  • 7. The POLPRED Model Proudman Oceanographic Laboratory ~950 1*1km grid squares 10 minute intervals 1 year of data 1/120° lat by 1/60° long 58°N to 59°40'N 04°00'W to 02°00'W Temporal or Spatial Level of tide Speed of current Direction Tidal Diamonds Long term statistics Particle tracking
  • 8. Modelled Tides (POLPRED) MSc Project of Lora Jane Dillon. POLPRED 1/120 x 1/60 “Orkney Model” under license from POL.
  • 9. GIS Representation of Summary Information
  • 10. Boat Survey and Analysis Speed variations vs time 0 0.5 1 1.5 2 2.5 3 3.5 12:10 12:20 12:30 12:40 12:50 13:00 13:10 13:20 13:30 13:40 13:50 14:00 14:10 14:20 14:30 14:40 14:50 15:00 15:10 15:20 15:30 15:40 15:50 Currentvelocity Area 1 Area 1 Area 3 Area 4 Area 5 Area 6 Area 7 Area 8 Area 9 Matching data on survey tracks (above) to low-resolution model data (below) Underway ADCP surveys
  • 11. • Current strengths can vary over distances of only 100 metres • Flood and Ebb Streams can be asymmetric • In Strength • In Position • In Direction • “Bi-directionality” of tidal currents is rare • Asymmetry • Tidal ellipses • Eddies • Vertical shear is mainly (but not always) restricted to near the sea bottom Detailed Characteristics of the Tidal Stream Resource
  • 12. Inner Sound on Flood
  • 14. How are the hydrodynamics altered by introducing energy extraction? If we introduce a tidal fence, significant current anomalies are inevitably introduced Large anomalies result from GigaWatt- scale extraction, with diminishing returns Currents → Sedimentation Dynamics → Habitat → Ecology
  • 16. Wave Climate • Offshore wave climate can be effectively measured by satellite altimetry • At sites such as Pentland Firth, there is a complex interaction of waves with bathymetry and currents •Validated wave model output is essential data for exposed tidal energy sites such as the Pentland Firth
  • 17. Wave Modelling Simple case of a uniform 1 metre sea propagating from the western boundary
  • 18. Remote Sensing Methods Radial Velocity by SAR ATI (X-SAR / SRTM). N.B. one colour cycle equates to a difference in velocity component of 4m/s. From Runge et al. (2004) “RASCAL PF”; Courtesy Lucy Wyatt and Jon Side N.B. Waves also! Coastal HF Radar SAR Along Track Interferometry
  • 19. Conclusions 1) The Pentland Firth is a genuine resource, but is also a valued and challenging environment 2) ERI emphasises observation and development of VALIDATED models 3) Characteristics need to be measured and modelled to scales of 10s of metres 4) ADCP survey methods (and fixed bottom-mounted ADCP) are effective but costly and time-consuming 5) Currents and waves should also be measured by remote sensing methods to extend spatial coverage.

  1. The potential market for marine renewable energy is by any standards large. Marine energy technology has the capacity to deliver 15-20% of UK energy needs[1]. It is estimated that in Scotland alone there is 21.5GW of exploitable marine resource and that by 2020 installed wave and tidal energy capacity in Scotland will be in the region of 15,000MW[2]. The level of marine energy development would represent at least £15bn of capital investment in Scotland alone. Estimates of employment in the sector vary between 6,000 and 24,000 by 2015[3]. Globally it is estimated that marine energy technology has the capacity to deliver between £60bn and £190bn of revenues annually requiring global investment in excess of £500bn13.
