A Hydrodynamic Modelling Framework for Strangford Lough Part 1: Tidal Model
Hydrodynamic models are a powerful tool that can be used by a wide range of end users to assist in predicting the effects of both physical and biological processes on local environmental conditions. This paper describes the development of a tidal model for Strangford Lough, Northern Ireland, a body of water renowned for the location of the first grid-connected tidal turbine, SeaGen, as well as the UK’s third Marine Nature Reserve. Using MIKE 21 modelling software, the development, calibration and performance of the model are described in detail. Strangford Lough has a complex flow pattern with high flows through the Narrows (~3.5 m/s) linking the main body of the Lough to the Irish Sea and intricate flow patterns around the numerous islands. With the aid of good quality tidal and current data obtained throughout the Lough during the model development, the surface elevation and current magnitude between the observed and numerical model were almost identical with model skill >0.98 and >0.84 respectively. The applicability of the model is such that it can be used as an important tool for the prediction of important ecological processes as well as engineering applications within Strangford Lough.

Foreshore Licensing and Leasing for Marine Renewables Projects - MRIA White Paper
Ireland’s offshore renewable energy resources have significant development potential and are considered among the best in the world. The practicably exploitable wave energy resource is estimated at more than 75% of Ireland’s 2006 electricity demand while our tidal resource also has significant potential. The Government’s Energy White Paper (2007) includes targets of 75MW generated from ocean energy sources by 2012 and 500MW by 2020. In order for Ireland to achieve these progressive targets and optimise the socio-economic benefits associated with exploitation of its marine energy resource, it is critical that public and regulatory policy enacts effective delivery mechanisms.
Key to delivery is the implementation of an appropriate Foreshore Licencing and Leasing process. The existing process, currently under review, operates on a ‘first come, first served’ basis which is felt to be inappropriate for appropriate development of the resource in the national interest. In light of the current review, due to be concluded in 2009, MRIA has prepared this Paper to communicate the Industry view on an effective Foreshore Licencing and Leasing process for marine renewable projects.

Ocean Energy in Ireland
Ocean energy, contained in the world’s waves and marine tidal currents, provides an untapped source of renewable energy and this publication focuses on ocean energy in Ireland in 2005.
Ocean Energy Initial Development Zones White Paper
The opportunity to derive energy from the Ocean is significant in Ireland, both from Wave and from Tidal sources. The potential is such that Ocean Energy represents a critical opportunity to create substantial wealth and employment on this island over the next twenty years and beyond. Key to this transformation of the island of Ireland into ‘Europe’s Battery’ is the achievement of the target set in the Republic by Government to have 500MW of Wave and Tidal capacity in operation by 2021.
The Marine Renewables Industry Association- which represents Ireland’s Marine Renewables industry in the Ocean Energy fields of Wave and Tidal- recognises that achieving the 500MW target over the next ten years will require a major coordinated effort across all Government Departments and Agencies and a focus on a small number of sea areas for developments towards 2020. The Association proposes in this Paper that four Initial Development Zones (IDZs) for Ocean Energy be prioritised by Government and that efforts to achieve the 2020 target be focused in these zones. The Paper demonstrates that this proposal is consistent with broad Government economic development policy as well as policies in Energy, Spatial Planning and Regional Planning.
This White Paper hails the progress made in Ocean Energy in Ireland to date, highlights the challenges which must be overcome and proposes measures to expedite further development. Specifically, this Paper identifies the priority Initial Development Zones, sets out the assumptions underlying them and indicates the next steps to be taken- urgent action, notably in Consenting where a Round to provide for initial exploration and exploitation of the IDZ’s is critical, is sought.

Research and Development and Ocean Energy
Ocean energy – wave and tidal generated electricity - is at the Research and Development, pre-commercial stage. Ireland has a significant effort underway in ocean energy R and D which represents a potential competitive advantage for the country particularly in light of other advantages such as the highly energy intensive wave resource, possible access to major markets through the Anglo Irish talks on electricity supply now underway and other factors.
This Paper records the views of the three key stakeholders in ocean energy R and D- Third Level institutions, Government Agencies and Industry. It sets out the boundaries to ocean energy at the present as discerned by these stakeholders and it identifies the five research priorities for the next few years: develop and grow the database; develop understanding of the economics of the industry; promote a series of projects to deal with practical engineering problems; continue to invest in infrastructure; and build the research effort into the environmental dimension to ocean energy. Overarching all of this is the need to provide funding for R and D in this (Government-determined) research priority area.

Strangford Lough and the SeaGen Tidal Turbine
The background to and outcomes of the Environmental Monitoring Programme (EMP) required by statutory regulators for the deployment of the SeaGen tidal turbine in Strangford Lough, Northern Ireland, an area with many conservation designations, are described. The EMP, which was set within the context of an adaptive management approach, considered possible effects of the device on local populations of seals and harbour porpoises, representative seabirds and benthic communities. The studies on seals were carried out on both local and regional scales. The ecological studies were complemented by detailed field and hydrodynamic modelling investigations together with a programme of mitigation measures designed to reduce collisions between seals and turbine rotors. In general only minor statistically significant changes in abundance, distribution and animal behaviour patterns were recorded, principally associated with small distributional shifts close to the turbine structure and with the likelihood that these changes were ecologically of little significance. The seal–rotor collision mitigation studies provided a base for the establishment of acceptable collision risk strategies. The EMP highlighted observational, methodological and statistical challenges in assessing the environmental consequences of marine energy devices. A brief review of related studies in Strangford Lough is included.

The Opportunity for Co-operation and Collaboration between Ireland and Scotland in Ocean Energy
Ireland, North and South, and Scotland are world leaders in the field of ocean energy and are endowed with substantial wave and tidal resources, excellent and growing Research and Development capacity and are home to many of the world’s leading companies in this field. Historically, Scotland has been ahead of Ireland in developing ocean energy, principally because of the strong commitment of Scottish political leaders to winning a commanding position for Scotland in the industry. On the island of Ireland, Northern Ireland has made commendable progress in exploiting its tidal resource but the Republic of Ireland has been the laggard despite its world-beating wave resource and its significant R&D effort. The position is changing in the Republic with positive signs of Government support including a new Bill to transform the consenting system (‘planning permission’) offshore while the Ocean Renewable Energy Development Plan is imminent.
Despite the progress, ocean energy in both Ireland and Scotland faces formidable challenges: the technology has a distance to travel before it reaches commercial ubiquity; the finance required to commercialise the technology is substantial; and there are significant issues of market access, particularly in Scotland, because, for example, wave and tidal resources tend to be distant from major grid capacity.
This Paper was drawn up to examine the scope for the various parties – particularly the Republic of Ireland and Scotland but also Northern Ireland– to work together. It is based on the views of a wide range of interests, mostly in Government and Industry, who expressed remarkably similar views regardless of geographical location. The Paper ends with a series of recommendations and suggests that these might form a series of work streams for the British Irish Council’s Marine Energy Committee.
The Supply Chain for the Ocean Energy Industry in Ireland
Ireland has an unprecedented opportunity to build a position of strength as a supply chain to the world- wide ocean energy industry. The policy landscape – including required legislation and provision of a policy framework for ocean energy- is moving in a positive direction but a greater sense of urgency is required. Most importantly, Government is negotiating an export framework with the United Kingdom which could provide a market for all forms of Irish marine energy and exploit our formidable offshore energy natural resource with potentially significant new job creation.
The development of an export market with the UK would provide a market for Irish ocean energy, but enabling actions are still required. Firms in the supply chain are aware of the ocean energy opportunity but need the confidence which would be provided by more overt Government leadership of the sector and, most important, the development of real business opportunities.
In particular, the Irish Government needs to give the private sector the confidence to invest in ocean energy and enable business interests to build a base to serve world-wide markets for ocean energy equipment and services. This can be achieved through the provision of a:
An allocation of ocean energy Renewable Energy Feed-In Tariff (REFIT) to incentivise early investment
Clear consenting process administered by a single body (An Bord Pleanála) offering developers – whether of demonstration arrays or, later, of export oriented ocean energy farms - a clear route to a fully consented site...with a proactive landlord in the form of the Department of Environment, Community and Local Government
The absence of any of the elements would be a severe impediment to the growth of ocean energy in Ireland.
Third Level Education Needs of the Ocean Energy Industry
The island of Ireland faces an economically transformative opportunity in ocean energy generated from waves and tides. The independent SQW report forecasts substantial income and job potential, particularly in the 2020’s when ocean energy technology is likely to reach maturity and to be deployed on a commercial scale. The opportunity will be realised on two planes- enterprise (e.g. development of the supply chain in Ireland to support the industry not only here but elsewhere in Europe) and export (e.g. through interconnectors to the UK and elsewhere).
A key factor in determining Ireland’s success in this challenging industry will be the quality and availability of appropriately skilled graduates from the Universities and the Institutes of Technology and other bodies, notably in engineering. This Paper presents the findings of a review of this issue by the Marine Renewables Industry Association with expert bodies and with those involved in the emerging ocean energy industry. The principal findings were:

Wave and Tidal Energy Market Deployment Strategy in Europe
Despite an investment crisis brought on by the biggest economic recession Europe has seen since the Second World War, the EU is on track to fulfil its ambitious 2020 renewable energy targets. In 2012, Europe’s renewable energy industry employed 1.2 million people and generated €130 billion of economic activity1, the vast majority of which did not exist just one decade ago. The reasons for this are straightforward. Targets at the EU level have provided long-term regulatory stability, matched with EU funding, which reduces risk by advancing technologies along readiness levels. Nationallevel targets in every Member State have resulted in governments putting in place capital and revenue support mechanisms, creating a vibrant market for renewable energy and generating volume production which has driven remarkable cost reduction across the most mature renewable energy technologies. Although it has now taken the first generation of renewable energy technologies to competitive levels, Europe still needs to diversify its electricity supply further if it is to meet its 2050 policy objective of reducing greenhouse gas emissions to 80 – 95% below 1990 levels2. Increased energy generation from renewable sources has been identified by the European Commission as a ‘no-regrets option’ for meeting these objectives3. Wave and tidal energy are the next generation of renewable energy technologies, and they will be needed if Europe is to meet its decarbonisation targets. These technologies can also support better grid integration for all renewables. Wave and tidal projects can, for example, be developed in areas of low solar or wind resource. Electricity generation from wave and tidal is also out of sync with other renewable technologies, and will provide further balancing effects for European transmission systems. However, binding renewable energy targets for the post-2020 period are necessary in order to provide clarity for investors. In a tough economic climate, and without binding targets, the incentive to shift from the status quo will be significantly weakened. Wave and tidal energy technologies must now find a route to market in more uncertain times than their predecessors.
