“…The energy system costs include investment, operation and maintenance costs, plus the costs of imported fuels, minus the incomes of exported fuels, and the residual value of technologies at the end of the horizon (Loulou et al 2005). The Irish TIMES model (Ó Gallachóir et al 2012) has been used to test a number of future energy and emissions' policy scenarios, such as impact of climate mitigation policy on Irish energy system by 2020 (Chiodi et al 2013a) and 2050 (Chiodi et al 2013b), energy security (Glynn et al 2014), impact of limiting the bioenergy resources (Chiodi et al 2015a), and integrated agricultural and energy systems modelling (Chiodi et al 2015b).…”

“…Ireland must also ensure that at least 16 % of its gross energy consumption and 10 % of energy used in transport are generated from renewable sources by 2020 (European Parliament and Council 2009a). Ireland is facing significant challenges to meet these ambitious climate mitigation targets (Chiodi et al 2013a), and has a lot of ground to cover to meet the 16 % renewable energy target (Pye et al 2014). The country experienced a continuous increase in energy use, particularly between 1990 and 2007.…”

The greenhouse gases (GHG) emissions from land-use change are of particular concern for land-based biofuels. Emissions avoided by substituting fossil fuels with biofuels may be offset by emissions from direct and indirect land-use changes (LUC). There is an urgent need to investigate what impact land-use change emissions may have on the expansion of bioenergy and biofuels, in the context of EU mitigation policies. This paper focuses on Ireland, which faces a number of challenges in delivering its renewable energy and GHG reduction targets. The Irish TIMES energy systems model was used to assess the impact of a range of land-use change emissions' levels on the evolution of Ireland's low-carbon energy system. A reference scenario was developed where LUC is ignored and Ireland achieves a least-cost low-carbon energy system by 2050. If high indirect land-use change (ILUC) emissions are included, this results in a decrease by 30 % in bioenergy and a 68 % increase in marginal abatement costs by 2050. Hydrogen is used instead of bioenergy in the freight sector in this scenario, while private cars are fuelled by renewable electricity. If GHG emissions from ILUC were considered less severe, indigenous grass biomethane becomes the key biofuel representing 31 % of total bioenergy consumption. This is in line with recent research in Ireland of the key role that grass biomethane can play.

“…Chiodi et al [18] analyzed whether or not Ireland's greenhouse gas reduction targets were realistic by using the TIMES model. Ireland had proposed relatively aggressive targets of reducing Non-Emission Trading Scheme (ETS) greenhouse gas emissions by 25% of its 2005 levels by 2020.…”

According to the Paris Agreement at the 21st Conference of the Parties, 196 member states are obliged to submit their Intended Nationally Determined Contributions (INDC) for every 5 years. As a member, South Korea has already proposed the reduction target and need to submit the achievement as a result of the policies and endeavors in the near future. In this paper, a Korean bottom-up energy system model to support the low-carbon national energy R&D roadmap will be introduced and through the modeling of various scenarios, the mid-to long-term impact on energy consumptions and CO 2 emissions will be analyzed as well. The results of the analysis showed that, assuming R&D investments for the 11 types of technologies, savings of 13.7% with regards to final energy consumptions compared to the baseline scenario would be feasible by 2050. Furthermore, in the field of power generation, the generation proportion of new and renewable energy is expected to increase from 3.0% as of 2011 to 19.4% by 2050. This research also suggested that the analysis on the Energy Technology R&D Roadmap based on the model can be used not only for overall impact analysis and R&D portfolio establishment, but also for the development of detailed R&D strategies.

“…Ireland has not established a firm mandatory target for the year 2050, but does have ambitious and legally binding targets for GHG emissions reduction targets for the year 2020 (this is dealt with in detail in a separate paper [18]). Under Directive 2009/29/EC approximately half of GHG emissions are due to large point source emitters (within part of industry, power generation and transformation) and are regulated under the European Emissions Trading Scheme (ETS).…”

Cite as: Chiodi, A., Deane, P., Gargiulo, M., Gallachóir ABSTRACTThis paper assesses through scenario analysis the future role of bioenergy in a deep mitigation context. We focus in particular on the implications for sustainability -namely, competing demands for land-use, import dependency, availability of sustainable bioenergy and economics. The analysis here is limited to one Member State, Ireland, which is an interesting case study for a number of reasons, including significant import dependency and recent acceleration in renewable energy deployment. We used the Irish TIMES model, the energy systems model for Ireland developed with the TIMES model generator, for this scenario analysis. Long term, least cost mitigation scenarios point to bioenergy meeting more than half of Ireland's energy needs by 2050. The results of this paper point to the impact of tightened sustainability criteria and limitation on bioenergy imports, namely the increased use of indigenous bioenergy feedstocks, increased electrification in the energy system, the introduction of hydrogen and higher marginal abatement costs.
