Nuclear energy considered in bid to cut emissions
Eirgrid, which controls the country’s electricity transmission network, published a report drawn up by Poyry energy consultants which examines the various technology options open to Eirgrid if they want to achieve the 2050 target. These also include accelerating beyond the planned target of generating 40% of electricity from renewables by 2020, further interconnection with Britain and Europe and investing in increased energy storage. Ireland has just 11 days worth of gas supply storage whereas in France they have 92 days and 84 days in Germany.
According to Eirgrid, the move towards a de-carbonised electricity structure is driven by climate change and our lack of energy security. Ireland has the fourth highest dependency on imported fuel in Europe. The advent of the smart electricity grid and electric cars is also pushing the need for change. Eirgrid chief executive Dermot Byrne said “it was not about picking winners at this stage”.
“Carbon capture and storage and nuclear energy are both found to be capable of reducing overall power sector emissions while also diversifying away from our dependence on gas. It must be noted, though, that there are technology and public acceptance issues surrounding both that may yet take years to resolve,” he said.
“While cost competitiveness and supply reliability are key considerations, there are other complex issues that are considered in the report. Power systems need a range of different types of generators and this is reflected in each portfolio. The viability of new technologies and risks associated with technology development is assessed. Public acceptance, especially associated with delivery of large projects, is also considered.”
Ireland is on course to have 15% of its electricity from renewables this year and is focusing on having 40% by 2020. However, the renewable sector has warned that red tape is holding up many projects.
