What & Who is MAREN?
Overview of MAREN:
Modelling of marine renewable energy potential and impact across the Atlantic Area
The project is co-financed with the support of the EU Interreg Atlantic Area Programme,
bringing a wide range of technological expertise. The work is ongoing and runs until 2012
(2013).

Why?
“Optimising the energy extraction potential of the
marine resource whilst minimising the negative
hydro-environmental impact across the Atlantic
Area”
MAREN Project Overview
The MAREN Project investigates the marine renewable energy forms of:- offshore wind,
tidal current, tidal barrages and lagoons, and wave, in the Atlantic Area to
produce:
1.
Country Modelling Case Studies
•
High resolution modelling and mapping of the resource potential
•
Assessment of marine renewable energy device performance
•
Assessment of the Environmental Impact
•
Future climate change scenarios – for resource, impacts and design
requirements
•
Carbon emission life-cycle analysis
2. Comparative analysis of EIA and SEA protocol across the Atlantic corridor

Hydro-environmental modelling:
 The Severn Barrage under different generation modes – resource and impact
 The North Wales tidal lagoons – resource and impact including coastal flooding
 Energy harbours along the Severn Estuary and Bristol Channel
Proposals:
 Bridgewater Lagoon - resource potential and hydro-environmental impact
 Loughor Barrage - resource potential, hydro-environmental and economic impact
modelling
Other ideas to work from existing modelling capabilities of:
 Energy assessment
 Water quality
 Water speed
 Flood risk
 Pathogens
 Fish habitat modelling

Offshore Wind
IH Cantabria, Spain
The aim of their work is two-fold:
• To present two novel wind and wave re-analysis databases to be used for wind farm
offshore applications.
• To describe a corrective method using instrumental observations.
These tools provide marine climate information for addressing issues about optimal design for
offshore wind farms, such as:- optimal location, operation and maintenance strategies, etc.
New Methods used: SeaWind and GOW 2.1 databases provide 21 years continuous long
time series of wind and wave climate on a high resolution grid, which can be used for offshore wind farm planning and design. Both SeaWind and GOW databases have been
corrected using a parametric calibration method based on nonlinear regression
These models are being used to identify key sites in the Atlantic Area based on
resource potential:
• Pilot study in each area – Severn, Shannon, W. France - Brest, Spain Santander, and
Portugal offshore Lisbon
Further work: Models for each site need higher resolution validation data
Tidal Stream Studies
Hydro-environmental modelling:
 The Shannon Estuary (Ireland) – resource and impact
 The Severn Estuary (UK) – resource and impact
 La Rance (France) - impact
Proposals:
 Shannon Estuary – resource potential and hydro environmental impact
 Severn Estuary – resource potential and hydro environmental impact
Other ideas to work from existing modelling capabilities of:
 Energy assessment
 Changes to hydrodynamic regimes
 Tidal ellipse analysis
 Climate impacts – especially flooding
 Multi-scale modelling: Cylindrical coordinates; Rotated/nested grids
Wave
IST, University of Lisbon, Portugal
Work to date:
A wave prediction system based on two state-of-the-art spectral models, WAVEWATCH
III ™ and SWAN, was implemented in order to evaluate UK’s wave conditions and to
assess potential wave energy extraction.
Case Studies:
• Wave Hub test site, Cornwall
• Pembrokeshire Coast
Validation tests are carried out with buoy data from the British Oceanographic Data
Centre so that the model's performance can be evaluated.
Further work: Refinement of the calibration with higher resolution data sets.
Paper available on request.
Stakeholder Engagement Work
PURPOSE: Research is only as good as the people and
environment it can help. MAREN strives to involve stakeholders to
produce useful outputs with the research.
