“…This highlighted the significance of upstream (particularly fugitive) emissions, in contrast to power plant operational or 'stack' emissions, as well as their technological and policy implications. The findings were reinforced by the carbon and environmental footprint analysis of Alderson et al (2012), who examined the environmental impacts associated with UK power generation based on historic data and a set of three alternative energy scenarios to 2050. They found that their projections indicated that the UK electricity supply industry could only be near-decarbonised by 2050 under various low carbon scenarios.…”

“…Subsequently, following the development of version 2.1 of the pathways, a similar study was carried out and is reported here that adopted the same methodology. Earlier studies of the carbon and environmental footprints of low carbon UK energy futures (by, e.g., Alderson et al, 2012) suggest that refinements of the technical elaboration or quantification of the pathways are unlikely to make significant differences to their environmental impacts reported. In this present study, similar trends were observed in both iterations, although version 2.1 suggests greater decarbonisation by 2050.…”

“…The focus here is on the implications of upstream, particularly fugitive, CO 2 e emissions in relation to the power generators (including the consequences for the adoption of CCS facilities in the power sector) and the modelling of future UK electricity projections on to around 2050. This work forms part of an ongoing research effort aimed at evaluating and optimising the performance of various sustainable energy systems (see, for example, Allen et al, 2008;Hammond, 2011; in the context of transition pathways to a low carbon future for the UK (Alderson et al, 2012;Foxon et al, 2010).…”

Upstream environmental burdens arise from the need to expend energy resources in order to extract and deliver fuel to a power station or other users. They include the energy requirements for extraction, processing/refining, transport and fabrication, as well as methane leakages from coal mining activities – a major contribution – and natural gas pipelines. The upstream carbon dioxide emissions associated with various power generators and UK electricity transition pathways towards a ‘low carbon’ future have been evaluated on a ‘whole systems’ basis. Carbon dioxide capture facilities coupled to fossil-fuelled plants are shown, for example, to deliver only a 70% reduction in greenhouse gas emissions (including both upstream and operational emissions), in contrast to the normal presumption of a 90% saving. In addition, the present UK greenhouse gas trajectories associated with transition pathways to 2050 are found to differ significantly from those produced by the British government's Department of Energy and Climate Change and its independent Committee on Climate Change. These bodies do not currently account for upstream, ‘fugitive’ greenhouse gas emissions. Therefore, there will actually remain further emissions upstream that are unaccounted for, even if the current UK carbon dioxide equivalent reduction targets are apparently met.

“…Various previous studies have been conducted to analyze the potential of the environmental policies or the low-carbon scenarios from the system perspective, but they have not considered the effects of the alternative energy adoption from the system perspective. Alderson et al [6] analyzed energy saving scenario for the United Kingdom (UK) by 2050, deriving that the GHG emissions reduction could be achieved at 46% by 2030. Ashina et al [7] studied the future low-carbon society road map in Japan and showed that the CO 2 emissions reduction rate would reach 31%-35% by 2030.…”

Abstract:We analyze the economic effects of greenhouse gases (GHG) reduction measures of the generation sector of South Korea to accomplish the 2030 GHG reduction target using a scenario-based approach. We estimate the GHG emission of the South Korean power industry in 2030 based on both the 7th Electricity Supply and Demand Plan and the GHG emission coefficients issued by the International Atomic Energy Agency (IAEA). We establish four scenarios for reduction measures by replacing the coal-fired power plants with nuclear power, renewable energy and carbon capture and storage, and liquefied natural gas (LNG) combined cycle generation. Finally, the nuclear power scenario demonstrates the most positive measure in terms of GHG reduction and economic effects.

“…Electricity generation presently contributes approximately 30% of United Kingdom (UK) carbon dioxide (CO 2 ) emissions [1,2], the principal 'greenhouse gas' (GHG) having an atmospheric residence time of about 100 years [3]. This share mainly arises from the use of fossil fuelled (coal and natural gas) power stations.…”

Several tidal power schemes have been proposed for the River Severn Estuary between the South West of England and Wales. An indicative technology assessment has been undertaken in order to evaluate the so-called 'Shoots Barrage' over its foreseen lifespan of 120 years in terms of its cradle-to-site, operation and maintenance requirements. It would be located just upriver of the Severn road crossings in the United Kingdom (UK), involve an estimated cost of £3.2 bn to construct, and could potentially generate around 2.7 TWh per year (or a little under 1% of UK electricity demand). This scheme is favoured by environmental groups, because to its more benign environmental impacts compared with the much larger, Cardiff-Weston scheme. The present analysis suggests that the proposed Shoots Barrage would yield relatively attractive 'figures of merit' in terms of its net energy and carbon emissions, although its financial performance is poorer than alternative power generators.
