    This is the author accepted manuscript. The final version is available from HeinOnline Law Journal LibraryIntroduction. In the face of the climate crisis, the future of the electricity industry is vital. Globally, the electricity sector ranks first in terms of greenhouse gas (GHG) emissions, accounting for 25% of such emissions in 2010. Among Organisation for Economic Cooperation and Development (OECD) countries, the figures are even starker: electricity is the number one contributor to climate change for this group, comprising 42% of GHG emissions.

    In situ study of sigma phase formation in Cr-Co-Ni ternary alloys at 800°C using the long duration experiment facility at Diamond Light Source.

    Get PDF
    The new long duration experiment facility on beamline I11 at Diamond Light Source has been used to study the kinetics of sigma phase formation in three Cr-Co-Ni alloys. Diffraction data acquired during in situ exposure at 800°C for 50 d showed progressive increases in the sigma fraction. This was accompanied by changes in the proportions of the other phases, which differed markedly between the alloys studied. These results demonstrate the capabilities of the long duration facility for the study of metallurgical phenomena over periods of months to years, a capability not previously available at a synchrotron source

    Distributed local energy: Assessing the determinants of domestic-scale solar photovoltaic uptake at the local level across England and Wales

    This is the final version. Available from Elsevier via the DOI in this record. Data availability: Data will be made available on request.The withdrawal of the Feed-in Tariff (FiT) by the UK Government at the end of March 2019, which rewarded low carbon electricity generators with subsidy payments, has led to doubts over the future of small-scale generation in the country's energy system. This study contributes to navigating this post-subsidy uncertainty by identifying the factors associated with the uptake of a domestic-scale technology, solar photovoltaics (PV), in England and Wales, and exploring its spatial distribution. It uses FiT installation data from Ofgem, available at a fine-grained spatial resolution for the period April 2010–September 2019, to test the effect of social, housing, political, energy and environmental factors. It is shown that population demographics, housing density, size, type and tenure, and energy consumption practices are important factors influencing the uptake of domestic PV at the local level. The South West and East of England are identified as regions of unexpectedly high uptake, controlling for the other factors. This is, at the time of writing, the first attempt to model PV uptake at a fine-grained spatial level across England and Wales.Economic and Social Research Counci

    Sources of Risk and Uncertainty in UK Smart Grid Deployment: An Expert Stakeholder Analysis

    Get PDF
    The shift to increasingly smarter grids will require preparation and planning on the part of a diverse selection of current and future stakeholders. There are substantive sources of uncertainty that will impact on the adoption of smarter grid solutions. Risks and uncertainties are placed in one of seven categories: markets, users, data and information, 28 supply mix, policy, investment conditions, and networks. Each of these has the potential to add risk to the planning profiles of the stakeholders involved. Here, UK stakeholders drawn from industry, government, regulators, and academia are canvassed about potential sources of uncertainty within the UK’s electricity sector and the attendant risks that might be engendered by them.UK Research Council

    Grid island energy transition scenarios assessment through network reliability and power flow analysis

    Get PDF
    This is the final version. Available on open access from Frontiers Media via the DOI in this record. Data Availability Statement: The original contributions presented in the study are included in the article/Supplementary Material. Further inquiries can be directed to the corresponding author.This paper presents a methodology for the reliability and power flow analysis of islands or off-grid power networks for situations of scarce data and information. It offers a new and pragmatic approach to derive the required power network information, including the power cable parameters and the load at each power node. The paper aims to present the developed methodology, and to illustrate its application, using Ushant Island as a case study. The assessment of the current power network status and the reliability analysis are presented. Grid performance parameters are further compared for conventional diesel generator operation and renewable energy generation scenarios, demonstrating the advantages of replacing the existing diesel units with renewable energy sources in terms of system reliability. The analysis shows that by introducing renewable energy systems to the island’s grid, the reliability of the grid increases by up to 50% and cable capacity usage reduces by up to 30%. Furthermore, this work suggests that it would not be necessary to modify the grid cables when substituting the diesel generator. The paper will be of interest to network planners, community stakeholders, project developers and decision-makers concerned with renewable energy investment on islands and in remote rural areas.Intelligent Community Energy (ICE) projec

    Adjacent level discitis after anterior cervical discectomy and fusion (ACDF): a case report

    Get PDF
    This report describes a case of spondylodiscitis occurring adjacent to levels at which anterior cervical discectomy and fusion was performed. The objective is to describe a rare cause of spondylodiscitis and discuss its successful management. Post-operative discitis involving the same level is a known occurrence. We report an interesting case of spondylodiscitis occurring at the adjacent level of fusion, and to our knowledge this is the first such case reported in literature. A two-level decompression and fusion was performed at C5–6 and C6–7 levels with PEEK cages and anterior cervical plating in a middle-aged gentleman for persistent axial neck pain and left-sided radiculopathy involving C6 and C7 distribution. After 6 weeks, the patient presented to us with complaints of mild paresthesia in the abdomen and extremities. Radiological investigations including plain radiographs and MRI revealed a surprising finding of discitis at C4–5 level with an associated epidural abscess. In view of the patient’s myelopathic symptoms, surgical debridement and decompression of the spinal cord was performed. The plate and screws were removed, the cages were left intact, and the C4–5 disc level was reconstructed with tricortical iliac crest autograft. No further instrumentation was performed. The biopsy specimen from the disc at C4–5 level grew Serratia marcescens. It was contemplated that C4–5 discitis was initiated by inoculation of bacteria at the superior endplate of C5 by contaminated vertebral pins/drill-bit or screws. Adjacent level discitis is a rare but potentially serious complication of anterior cervical fusion. A high index of suspicion of infection is necessary if the patient complains of new symptoms after anterior cervical fusion. Thorough assessment and aggressive treatment is necessary for successful management

    Scenarios for the Development Smart Grids in the UK — Synthesis Report

    Research report | https://ukerc.ac.uk/publications/scenarios-for-the-development-of-smart-grids-in-the-uk‘Smart grid’ is a catch-all term for the smart options that could transform the ways society produces, delivers and consumes energy, and potentially the way we conceive of these services. Delivering energy more intelligently will be fundamental to decarbonising the UK electricity system at least possible cost, while maintaining security and reliability of supply. Smarter energy delivery is expected to allow the integration of more low carbon technologies and to be much more cost effective than traditional methods, as well as contributing to economic growth by opening up new business and innovation opportunities. Innovating new options for energy system management could lead to cost savings of up to £10bn, even if low carbon technologies do not emerge. This saving will be much higher if UK renewable energy targets are achieved. Building on extensive expert feedback and input, this report describes four smart grid scenarios which consider how the UK’s electricity system might develop to 2050. The scenarios outline how political decisions, as well as those made in regulation, finance, technology, consumer and social behaviour, market design or response, might affect the decisions of other actors and limit or allow the availability of future options. The project aims to explore the degree of uncertainty around the current direction of the electricity system and the complex interactions of a whole host of factors that may lead to any one of a wide range of outcomes. Our addition to this discussion will help decision makers to understand the implications of possible actions and better plan for the future, whilst recognising that it may take any one of a number of forms.UKR

    A structured approach for governing sustainable heat transitions in building renovation of towns and cities

    Get PDF
    This is the final version. Available on open access from IOP Publishing via the DOI in this record. Pioneer cities have demonstrated a willingness and capability to decarbonise local heat systems, but support is needed to scale up action. Heat decarbonisation is not simply a technical challenge, but also a political and social one; stakeholders must inform decisions about appropriate technological and policy solutions and will, in turn, be affected by them. Taking three dimensions of stakeholders, technology, and policy, a structured approach which centres stakeholders is presented to help local government to collaboratively find appropriate technology and policy solutions, both at the strategic scale across the municipality and in localised pilot projects, and explores how to initialise and support heat decarbonisation in more cities.European Regional Development Fund (ERDF)Province of South-Holland (Netherlands)Ministry of Economic Affairs and Climate Policy (Netherlands
