Options for the Development of Wave Energy in Ireland: A Public Consultation Document
The potential for development of wave, ocean current and tidal energy is the subject of growing international investigation. This document focuses on the status and development potential of wave energy in Ireland. While recognising that this technology is not in a position to contribute to national renewable energy targets within the Kyoto timeframe, it is oriented towards the longer term prospect of Ireland becoming a world-leading developer and manufacturer of the technologies that will enable the harnessing of ocean energy resources
Ocean Energy in Ireland
Ireland has a target of supplying 13.2% of its electricity consumption from renewable sources by 2010. The majority of this target is likely to be supplied from wind energy. It is likely that targets will increase in the longer term. This will require large deployments of other forms of renewable energy. Ocean energy, both wave and marine current tidal energy, may have a role to play in meeting longer term targets in Ireland. The resource, particularly the wave energy resource, is vast. Before these technologies become commercially viable researchers and developers must overcome the challenge of developing low cost, highly reliable, integrated systems. Given current efforts to develop technology, ocean energy may be deployed in small scale demonstrations by 2010; however it is not expected to contribute significantly to Irelandâs electricity supply before 2020. It is proposed to implement an ocean energy strategy to advance the speed at which ocean energy technologies are deployed in Ireland by increasing the capacity for research and development, both within academic institutions and commercial entities developing devices in Ireland. A structured and phased strategy of development supports may enable Ireland to utilize its ocean energy resource within a decade. The result could also see Ireland positioned with the potential to become a world leader in the manufacture and use of ocean energy systems
Wind/hydrogen hybrid systems: opportunity for Irelandâs wind resource to provide consistent sustainable energy supply
Ireland with its resource of wind has the potential to use this natural resource and sustain the countryâs power needs for the future. However, one of the biggest drawbacks to renewable energy generation, particularly wind generated electricity is that it is an intermittent and a variable source of power. Even at the "best" sites wind varies dramatically from hour to hour and minute to minute. This leads to two main problems:
1) When the wind drops below a lower limit or goes above a higher limit the turbine can shut down and electricity is not produced.
2) Energy is not stored when there is an excess of electricity generated on site.
Because of these problems wind power has a very low capacity credit and backup power is needed to handle the large fluctuation of production.
This paper introduces the energy system of Ireland and the targets that Irish operators are to achieve in the next decade. A review of energy storage options for Ireland is outlined including the use of hydrogen and fuel cell technology. It is concluded that a project similar to the Norwegian Utsira wind / hydrogen project could be piloted in Ireland and a site similar to Dundalk Institute of Technology could be used to demonstrate and test the system. Going forward to achieve high levels of renewable energy generation, similar distributed wind / hydrogen hybrid systems could reduce the need for curtailment of wind farms, save wasted energy, reduce backup power, reduce transmission losses, generate large revenue by selling power at peak times, ensure security of supply and reduce the need for costly interconnects to Europe
Greening healthcare: systematic implementation of environmental programmes in a university teaching hospital
peer-reviewedThe provision of healthcare creates significant environmental impacts, and their mitigation is being attempted in a variety of ways which vary from nation to nation in line with differing policy priorities and resource availability. The environmental performance of hospitals has been enhanced through, for example, green building, waste and energy management, and product design. However, unpredictable occupant behaviour, new research outcomes and evolving best practice requires healthcare to react and respond in an ever challenging and changing environment, and clearly there is no one set of actions appropriate in all jurisdictions. Many authors have pointed up negative environmental impacts caused by healthcare, but these studies have focused on particular aspects of mitigation in isolation, and are for this reason not optimal. Here it is argued that tackling impact mitigation through a whole system approach is likely to be more effective. To illustrate what this approach might entail in practice, an evaluation of a systematic implementation of impact mitigation in Ireland's largest teaching hospital, Cork University Hospital is presented. This approach brings together voluntary initiatives in particular those emanating from governmental and non-governmental organisations, peer supports and the adaptation of programmes designed originally for environmental education purposes. Specific measures and initiatives are described, and analysis of results and planned future actions provides a basis for evaluation of successes achieved in achieving mitigation objectives. A crucial attribute of this approach is that it retains its flexibility and connectivity through time, thereby ensuring continual responsiveness to evolving regulation and best practice in green healthcare. It is demonstrated that implementation in Cork resulted both in mitigation of existing impacts, but also a commitment to continual improvement. For such a systems approach to be widely adopted, the healthcare sector needs both leadership from regulators and stakeholders, and strong supports. In Cork it was found that environmental education programmes, especially action and reward based programmes, as utilised by the campus's academic affiliates in particular University College Cork, were especially effective as a framework to address sustainability challenges and should be developed further. However, within healthcare implementation of environmental initiatives must prioritise patient safety. This approach has now been adopted for delivery across the health services sector in Ireland.

Appraising infrastructure for new towns in Ireland
Copyright © 2013 ICE Publishing Ltd. Permission is granted by ICE Publishing to print one copy for personal use. Any other use of these PDF files is subject to reprint fees.Over a 20 year period 1996â2016, a new 223 ha town is being developed 10 miles west of Dublin's city centre on the south side of Lucan, County Dublin, in the Republic of Ireland (ROI). This âŹ4 billion âAdamstownâ development is the first of four planning schemes in ROI to be approved as a strategic development zone â an integrated planning framework deemed suitable for creating sustainable neighbourhoods in sites of strategic economic or social importance to the state. The creation of sustainable neighbourhoods in ROI is facilitated through the implementation of a checklist of 60 indicators. This paper critically examines the attempts being made to consider sustainability within the development's overall infrastructure plan, specifically: transport, energy and water services, information technology and waste. Inadequacies in the existing development are linked to shortfalls in the sustainability checklist, by way of a comparison of infrastructure-related indicators from the ROI checklist with those derived for the UK and exemplar European projects (i.e. Bedzed, UK and Freiberg, Germany). The subsequent legacy for future residents of Adamstown is then considered in the context of âwhat ifâ scenarios
Policy mixes for incumbency: the destructive recreation of renewable energy, shale gas 'fracking,' and nuclear power in the United Kingdom
The notion of a âpolicy mixâ can describe interactions across a wide range of innovation policies, including âmotors for creationâ as well as for âdestructionâ. This paper focuses on the United Kingdomâs (UK) ânew policy directionâ that has weakened support for renewables and energy efficiency schemes while strengthening promotion of nuclear power and hydraulic fracturing for natural gas (âfrackingâ). The paper argues that a âpolicy apparatus for incumbencyâ is emerging which strengthens key regimebased technologies while arguably damaging emerging niche innovations. Basing the discussion around the three technology-based cases of renewable energy and efficiency, fracking, and nuclear power, this paper refers to this process as âdestructive recreationâ. Our study raises questions over the extent to which policymaking in the energy field is not so much driven by stated aims around sustainability transitions, as by other policy drivers. It investigates different âstrategies of incumbencyâ including âsecuritizationâ, âmaskingâ, âreinventionâ, and âcapture.â It suggests that analytical frameworks should extend beyond the particular sectors in focus, with notions of what counts as a relevant âpolicy makerâ correspondingly also expanded, in order to explore a wider range of nodes and critical junctures as entry points for understanding how relations of incumbency are forged and reproduced
