Decarbonising the energy system in many countries (including both China and the UK) is likely to involve the large-scale deployment of renewable electricity generators with intermittent output and the electrification of energy services such as heat and transport that have very low load factors. These changes in electricity supply and demand will lead to a great need for energy storage. Our work for the Carbon Trust has estimated that the effective deployment of energy storage in the UK could reduce the cost of a low-carbon electricity system by £15 billion in 2030. The deployment and operation of storage is a complex task, since it can provide many different services, including energy arbitrage (buying off-peak and selling at higher peak prices), energy reserves, resolving transmission and distribution constraints and improving system reliability. The weight placed on each of these could affect the pattern of investment, and sophisticated planning tools are required to ensure that optimal decisions can be taken. We will improve these tools so that we can accurately represent a variety of storage systems. Much of the existing work on storage assumes that it might be used simply to postpone the "like for like" replacement of network assets that would otherwise be overloaded, but we will consider more radical options, using storage to actively manage the distribution network as part of the broader smart grid. We can use our models to calculate the economic value of energy storage when it provides a range of services to network companies and system users. We will measure the option value of having a storage system that can be deployed in much less time than it takes to get consent to build a transmission line, adding flexibility in how we respond to uncertainty over the future evolution of the energy system. It is important that such decisions are made on the basis of appropriate models, capable of quantifying the wide range of services that storage can provide, taking account of the way that electricity generation and demand varies over the course of the day and the year, and measuring the impact of transmission and distribution network effects. It is important to recognise that many countries (including the UK) have liberalised their electricity industries, and storage will only be pursued if companies believe that a viable business case exists. Work has started (via the Low Carbon Networks Fund) to test particular business models for demonstration projects, but this needs to be generalised. We will provide a quantified assessment of whether there is a business case for energy storage at present, and of what needs to be done to create one. This will involve a detailed study of the contracts that would be written around electricity storage, drawing lessons from existing arrangements for other kinds of storage, such as for gas or agricultural commodities. We will study how the rules of the electricity market could affect the choices of storage and generation technology. We will ask what policies are needed to ensure that storage can be economically viable when sensibly deployed and operated. We will identify technology policies that can help move energy storage from prototypes to large scale deployment. International transmission may complement energy storage within a country, and we will assess the potentially conflicting incentives if neighbouring countries adopt different strategies for dealing with intermittency. Too many debates around energy policy today are based on assertions without sufficient evidence. The models that we will develop, and the analysis that we will perform, will provide numerical estimates of the effectiveness of a range of policies, allowing regulators and other policy-makers to choose options that will lead to decarbonisation in the most effective way.

The aim of the Sustainable Eastside Project is to explore how sustainability is addressed in the regeneration decision-making process, and to assess the sustainability performance of completed development schemes in Birmingham Eastside against stated sustainability credentials and aspirations. The incorporation of sustainability into an urban regeneration program, such as Birmingham Eastside, appears best conceptualised as a complex decision-making process carried out by stakeholders who are embedded within the development process. The barriers to and enablers of sustainability (as identified in Phase I of this project) appear at various moments or locations within this complex. The timing and context of decisions are critical (examined in Phase II), and can cause path-dependency which then limits how sustainability features in final development plans. In Phases I & II, the research set in place a framework of cross-disciplinary knowledge and key partnerships; highlighted the importance of coherent integration of the three pillars of sustainability to enable the complexity of achieving urban sustainability to be sufficiently grappled with; gained access to key decision-making forums in Eastside; built strong links with key stakeholders in the area; and firmly integrated into the policy agenda for Eastside. In addition, researchers are working to establish a cross-cutting baseline dataset of developments in Eastside rigorously to measure change over time and the impact of particular decisions on the sustainability of the overall urban regeneration programme. In so doing the foundations for a zonal urban regeneration case study site are being established, augmented by the creation of a study facility, with library and hot desking, now available for researchers from SUE / IEP consortia, to study the application of research to practice. The emerging findings of Phase II have allowed researchers to develop a series of hypotheses about the timing of decisions for sustainability in a range of decision-making forums, and the extent to which path-dependency becomes problematic. In Phase III, a suite of innovative analytical tools will be employed to elucidate further the complexities and interactions of the key elements of the sustainability vision for Eastside. First, a Development Timeline Framework (DTF), a multi-disciplinary tool that makes explicit the path dependency of decisions toward achieving sustainability goals, and the conflicts and synergies between different sustainability objectives, will be used as the basis for further research. Second, a cross-cutting Sustainability Checklist (SC) applied to the DTF will allow each researcher to analyse the impact of timing and context of decisions for each sustainability element (e.g. biodiversity, public participation, space utilisation, local sourcing, and recycling). Third, an Industrial Ecology (IE) analysis will follow particular resources (e.g. water, aggregates) thus highlighting their interdependence, while a Social Impact Assessment (SIA) approach will enable assessment of the socio-cultural aspects of sustainability (not covered by the IE approach). This suite of tools underpins the delivery of the work package aims. This analysis will be undertaken on a case history site basis, using development sites within Eastside that are all currently 'live,' each site representing a different conceptualisation of sustainability. This provides a unique opportunity to evaluate the specific impact of early thinking about sustainability in the planning and design stages, and the impact of this timing and path-dependency on sustainability performance in the final built form.

The UK is committed to a target of reducing greenhouse gas emissions by 80% before 2050. With over 40% of fossil fuels used for low temperature heating and 16% of electricity used for cooling these are key areas that must be addressed. The vision of our interdisciplinary centre is to develop a portfolio of technologies that will deliver heat and cold cost-effectively and with such high efficiency as to enable the target to be met, and to create well planned and robust Business, Infrastructure and Technology Roadmaps to implementation. Features of our approach to meeting the challenge are: a) Integration of economic, behavioural, policy and capability/skills factors together with the science/technology research to produce solutions that are technically excellent, compatible with and appealing to business, end-users, manufacturers and installers. b) Managing our research efforts in Delivery Temperature Work Packages (DTWPs) (freezing/cooling, space heating, process heat) so that exemplar study solutions will be applicable in more than one sector (e.g. Commercial/Residential, Commercial/Industrial). c) The sub-tasks (projects) of the DTWPs will be assigned to distinct phases: 1st Wave technologies or products will become operational in a 5-10 year timescale, 2nd Wave ideas and concepts for application in the longer term and an important part of the 2050 energy landscape. 1st Wave projects will lead to a demonstration or field trial with an end user and 2nd Wave projects will lead to a proof-of-concept (PoC) assessment. d) Being market and emission-target driven, research will focus on needs and high volume markets that offer large emission reduction potential to maximise impact. Phase 1 (near term) activities must promise high impact in terms of CO2 emissions reduction and technologies that have short turnaround times/high rates of churn will be prioritised. e) A major dissemination network that engages with core industry stakeholders, end users, contractors and SMEs in regular workshops and also works towards a Skills Capability Development Programme to identify the new skills needed by the installers and operators of the future. The SIRACH (Sustainable Innovation in Refrigeration Air Conditioning and Heating) Network will operate at national and international levels to maximise impact and findings will be included in teaching material aimed at the development of tomorrow's engineering professionals. f) To allow the balance and timing of projects to evolve as results are delivered/analysed and to maximise overall value for money and impact of the centre only 50% of requested resources are earmarked in advance. g) Each DTWP will generally involve the complete multidisciplinary team in screening different solutions, then pursuing one or two chosen options to realisation and test. Our consortium brings together four partners: Warwick, Loughborough, Ulster and London South Bank Universities with proven track records in electric and gas heat pumps, refrigeration technology, heat storage as well as policy / regulation, end-user behaviour and business modelling. Industrial, commercial, NGO and regulatory resources and advice will come from major stakeholders such as DECC, Energy Technologies Institute, National Grid, British Gas, Asda, Co-operative Group, Hewlett Packard, Institute of Refrigeration, Northern Ireland Housing Executive. An Advisory Board with representatives from Industry, Government, Commerce, and Energy Providers as well as international representation from centres of excellence in Germany, Italy and Australia will provide guidance. Collaboration (staff/student exchange, sharing of results etc.) with government-funded thermal energy centres in Germany (at Fraunhofer ISE), Italy (PoliMi, Milan) and Australia (CSIRO) clearly demonstrate the international relevance and importance of the topic and will enhance the effectiveness of the international effort to combat climate change.
