Since the commencement of this study in mid-2007, carbon capture and storage (CCS) has moved up the political agenda and is now regarded as being potentially a major component of carbon abatement strategies, as early stage research and demonstration projects suggest that it is both technically and commercially viable to implement. The study adopted a phased approach through nine work packages (WP1 – WP9) agreed with the Client at the outset of the study, commencing with extensive data gathering and compilation to GIS to provide a preliminary geological assessment of likely storage basins and structures, both onshore and offshore the island of Ireland. This was followed by in-depth geological assessment of each identified structure/ basin, to quantify potential for storage of carbon dioxide (CO2). While geological assessment confirmed that there are significant data gaps for many basins, the study arrived at a reasoned, quantified assessment of Ireland’s geological storage potential. However, the paucity of deep geological data for many basins, particularly the offshore western basins, is the over-riding constraint to a full assessment of geological storage potential for CO2. The island’s major point source emissions were identified and power stations emerged as the priority candidates for capture if CCS economies of scale are to be achieved. An assessment of the all-island energy policy environment, current and future energy security and power generation mix, was used as a prism to provide an economic analysis of the most suitable technologies to capture, transport and sequester carbon, taking cognisance of Ireland’s demographics, energy requirements and the likely price of carbon to 2020 and beyond. The critical factor for the advancement of CCS on the island of Ireland is the geological viability of injection and storage in a suitable location on or offshore the Island. The depleting Kinsale Head gas field presents the best short term (<10 years) option, subject to further geological analysis and full reservoir simulation. Critically, there would be no logic in investing in expensive carbon capture technologies unless a proven geological storage site within acceptable socio-environmental risk parameters were to be available to take the captured CO2 into safe, long term storage. Geological Assessment of Storage Capacity An integrated assessment of the geological storage capacity of the island of Ireland was carried out for suitable onshore and offshore geological basins and structures (see Table Ex1 & Map 1 overleaf). The study estimated, using the techno-economic resource pyramid recommended by the international Carbon Sequestration Leadership Forum (CSLF, 2007), that the island has a total storage capacity of 93,115 Mt (see Figure 1). iii Figure 1: Techno Economic Resource Pyramid (CSLF 2007) This storage volume may be subdivided as follows: TOTAL QUANTIFIED CAPACITY 93,115 Mt x Theoretical Capacity: 88,770 Mt x Effective Capacity 3,507 Mt o of which 667 Mt is a subset of theoretical capacity; o of which 2,840 Mt is additional to theoretical capacity x Practical Capacity 1,505 Mt In the geological assessment, only theoretical, effective and limited practical capacities (see Table Ex.1 below) can be calculated due to limitations in deep geological data. To move these estimates up to the apex of the pyramid would require further geological and engineering studies for each structure. iv Table Ex.1 All-Island Ireland: Quantified Geological Storage Capacity for Carbon Dioxide ASSESSMENT OF THE ALL-ISLAND POTENTIAL FOR GEOLOGICAL STORAGE OF CO2 IN IRELAND QUANTIFIED GEOLOGICAL STORAGE CAPACITY (July 2008) Basin Structure Type Capacity Storage Quantified Classification Capacity Storage Capacity Mt Mt Kinsale Gas Field 330 South West Kinsale Gas Field Effective/ 5 1505 Spanish Point Gas Field Practical 120 East Irish Sea Oil & Gas Field 1050 Portpatrick Basin Sherwood Sandstone selected 37 structures Effective (subset of Central Irish Sea Sherwood Sandstone 630 (667) theoretical structures capacity) 667 Lough Neagh Basin Enler Group selected structures 1940 Effective Kish Bank Basin Sherwood sandstone structures (additional to 270 2840 East Irish Sea Basin Ormskirk structures theoretical 630 capacity) 2840 Celtic Sea - 1 structure in the Cretaceous A 40 sand Portpatrick Basin/ whole basin 2700 Larne Peel Basin Sherwood Sandstone whole Theoretical 68000 88770 basin NWICB Dowra Basin whole basin 730 Central Irish Sea whole basin 17300 Kish Bank Basin Carboniferous sandstone and coal Rathlin Basin Sherwood Sandstone, Permian and Carboniferous Celtic Sea Cretaceous A sand Porcupine Basin Theoretical / Slyne/Erris Basins un-quantified

Geological history The oldest rocks in County Down are 417-495 million years old [Ma] and consist of mudstones and volcanic rocks. At that time County Down lay beneath a deep ocean, on the edge of an ancient continent made up of Scotland, north America and the north of Ireland. A huge ocean separated this continent from the rest of Ireland, England, Wales and Europe. Over millions of years, this ocean closed and the two ancient continents collided, heating and deforming the rocks to form slates. The same rock types occur from Longford, through County Down and into the Southern Uplands of Scotland. Around 350 million years ago, in the early Carboniferous, sea level slowly rose to flood across the landscape.

    Draft NMPF Submissions, Marine Planning Section Department of Housing, Planning and Local Government Newtown Road Wexford, Y35 AP90 Emailed to [email protected] 30th April 2020 Submission – Draft National Marine Planning Framework (NMPF) Dear Sir/Madam, Thank you for providing us with the opportunity to comment on the Draft National Marine Planning Framework (NMPF). Founded in 1964, Kilsaran Concrete is the largest privately owned concrete and construction materials company in Ireland. Kilsaran remains a family owned Irish company producing quality construction material from 20 large quarries and 23 nationwide state-of-the-art concrete production facilities. Accordingly, Kilsaran has an intimate knowledge of terrestrial planning framework as it pertains to the sourcing and delivery of essential construction raw materials and concrete manufactured products. Kilsaran formed part of a group of companies that participated in the IMAGIN1 Project. The overall aim of the IMAGIN project was to facilitate the evolution of a strategic framework within which the exploitation of marine aggregate resources from the Irish Sea may be sustainably managed with minimum risk of impact on marine and coastal environments, ecosystems and other marine users. IMAGIN identified significant deposits of sand and gravel in the Irish Sea. We wish to have input on the design of a future marine planning framework for Ireland, and help to realise Ireland’s marine potential as a sustainable source of construction aggregates. We hope you find our comments useful and we would be happy to discuss them further with you, should that be required. 1 Kozachenko, M., Fletcher, R., Sutton, G., Monteys, X., Van Landeghem, K., Wheeler, A., Lassoued, Y., Cooper, A.

  • The Value of Reducing Minimum Stable Generation for Integrating Wind Energy
    The value of reducing minimum stable generation for integrating wind energy 1* 2 3 4 M. L. Kubik , P. J. Coker , Mark Miller and J.F.Barlow 1,4 Technologies for Sustainable Built Environments, University of Reading, United Kingdom 2 School of Construction Management and Engineering, University of Reading, United Kingdom 3 AES Kilroot, Carrickfergus, County Antrim, United Kingdom * Corresponding author: [email protected] ABSTRACT The integration of wind energy is a major driver toward grid decarbonisation in a number of electricity systems. However, no large-scale electricity grid is able to operate without some minimum level of conventional generation, which is required for both system security and to maintain power quality. This minimum stable generation level caps the amount of wind energy that can be used to satisfy system demand, and any excess must be curtailed if it cannot be stored. The curtailment of wind generation is undesirable for wind developers as it reduces their economic viability and increases costs for the system. It is also undesirable for the goal of reducing the carbon intensity of the grid as zero-carbon generation is held back in order for fossil fuel based conventional generation to run. With increasing wind capacity this problem becomes more severe. Certain modifications can be made to conventional generation to reduce their minimum stable generation levels, with differing cost implications. This paper examines the system benefits of reducing the minimum stable generation level of Kilroot power station for the Northern Ireland electricity system under the 40% wind penetration level planned for 2020. Keywords: Variability, intermittency, conventional generation, minimum stable generation 1.
