Ireland imports the vast majority of its energy – more than most European countries. Global energy demand will continue to increase over the coming decades so that sourcing secure and reliable energy at a reasonable cost is critical to Irish economic development. Technologies to produce sustainable and clean energy forms are being developed, however these will not meet predicted demand in the medium-term so that transitional energy supplies are required. In an Irish context, finding and producing hydrocarbons from offshore sedimentary basins has the potential to provide secure energy resources, with natural gas providing a relatively clean form of energy in the transitional period. iCRAG’s research in this area is leading to better understanding and forecasting of the geological setting of hydrocarbons especially offshore Ireland. We aim to strengthen Ireland’s position as an international leader in key hydrocarbon research themes, and to advise government in optimising exploration and development strategies by provision of independent scientific information and exploration models.
