1 MAREN Project What? Who? Why? What next? Atlantic Area Marine Economy Conference, Malahide February 7th 2012 Co-financed with the support of the European Union ERDF Atlantic Area Programme Investing in our common future Co-financed with the support of the European Union ERDF Atlantic Area Programme Investing in our common future

2 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). MAREN TEAM Cardiff - Tidal Barrages & Impoundments: Dr Bettina Bockelmann Evans, Prof. Roger Falconer, Dr Reza Ahmadian National University of Ireland, Galway - Tidal Stream: Dr Michael Hartnett IHC - University of Cantabria, Spain - Offshore Wind: Prof. Inigo Losada Centec, Instituto Superior Tecnico, Portugal - Wave: Prof. Carlos Guedes Soares Ifremer, France - La Rance Barrage: Dr Nicolas Desroy Other partners - Policy makers, private & public sectors

3 Why? Optimising the energy extraction potential of the marine resource whilst minimising the negative hydro-environmental impact across the Atlantic Area

4 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

10 IH Cantabria, Spain The aim of their work is two-fold: Offshore Wind 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

11 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

12 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.

13 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. ENGAGEMENT EVENTS: MAREN Initiation Meeting in North Wales, Feb 2010 SEP Annual Event, Bristol, Aug 2010 MAREN Project Meeting in Lisbon, Sep 2010 MEP Annual Event, Pembrokeshire, Mar 2011 MAREN sub meeting at the OCEANS conference, Santander, Jun 2011 MEP Working Group Meeting, Aug 2011 MAREN-ICE Business Breakfast Meeting, Cardiff, Sep 2011 SEP Annual Event, Cardiff, Sep 2011
