Heat demand in the UK accounts for around 44% of final energy consumption and is currently predominantly obtained by burning natural gas and oil, representing about 90% of the fuel share, while renewable energy sources supply only a fraction of it. Recent legally binding net-zero targets for greenhouse gas emissions (by 2045 in Scotland and by 2050 for the UK), will truly test our nation's technical and engineering competence and ability to innovate. The net-zero transition will not only require radical changes in technologies-it will also result in a profound impact on our society. A targeted decarbonisation framework, built from the participation and contribution of every home and every customer, is needed, so each of them may find optimal place and role as a fully functioning part of a wider smart energy system. This will require innovation. DISPATCH asserts that a net-zero transition in the UK should be planned and realised as a "bottom-up" and "user-centric" approach, where scalability and flexibility are obtained through the aggregation, sharing and control of the resources of individual customers, in such a way that the search for optimal solutions always starts with customers' needs and always ends without reducing customers' comfort levels and sacrificing their wellbeing. DISPATCH will focus on multi-vector energy solutions for decarbonisation of heating and cooling in residential and typical commercial applications (office buildings, educational facilities, etc.). These can be specified as generic parameterised models, as opposed to medium and large industrial and non-domestic applications. Our decarbonisation framework will also include cooling, which is anticipated to increase due to climate change-caused global warming (since 1884, all of the UK's ten warmest years occurred in years from 2002), but also due to provision of automatic or user-set temperature regulation by reversible heat pumps. Furthermore, as the net-zero transition through electrification of heating requires electrical-thermal solutions to be better in all aspects than the currently predominant natural gas infrastructure for heating, we will use electrification of heating as a "reference case" for comparative evaluation and ranking of other considered decarbonisation routes. Arguably, the highest potential for the provision of flexibility and balancing services is through increased customer participation in energy management and coordinated shifting of energy demands in the UK's 27 million homes and 1.4 million SMEs. However, to ensure wider customer engagement and to increase their willingness to take part in various demand-side management (DSM) schemes, they should be able to access appropriate energy exchange and energy trading services for their voluntary or interest-based participation. DISPATCH approaches the above challenges as actual opportunities for exploring synergies, interoperabilities and the overall integration potential of different energy vectors, in order to identify the most cost-effective solutions for reshaping and redistributing energy flows. For example, we will repurpose balancing and demand shifting controls used in normal operating conditions as low-cost resources for automated frequency response in emergency conditions, and compare its benefits with recently introduced procurement of stability as an ancillary service by NGESO.

The EPSRC Centre for Doctoral Training in Renewable Energy Northeast Universities (ReNU) is driven by industry and market needs, which indicate unprecedented growth in renewable and distributed energy to 2050. This growth is underpinned by global demand for electricity which will outstrip growth in demand for other sources by more than two to one (The drivers of global energy demand growth to 2050, 2016, McKinsey). A significant part of this demand will arise from vast numbers of distributed, but interconnected devices (estimated to reach 40 billion by 2024) serving sectors such as healthcare (for ageing populations) and personal transport (for reduced carbon dioxide emission). The distinctive remit of ReNU therefore is to focus on materials innovations for small-to-medium scale energy conversion and storage technologies that are sustainable and highly scalable. ReNU will be delivered by Northumbria, Newcastle and Durham Universities, whose world-leading expertise and excellent links with industry in this area have been recognised by the recent award of the North East Centre for Energy Materials (NECEM, award number: EP/R021503/1). This research-focused programme will be highly complementary to ReNU which is a training-focused programme. A key strength of the ReNU consortium is the breadth of expertise across the energy sector, including: thin film and new materials; direct solar energy conversion; turbines for wind, wave and tidal energy; piezoelectric and thermoelectric devices; water splitting; CO2 valorisation; batteries and fuel cells. Working closely with a balanced portfolio of 36 partners that includes multinational companies, small and medium size enterprises and local Government organisations, the ReNU team has designed a compelling doctoral training programme which aims to engender entrepreneurial skills which will drive UK regional and national productivity in the area of Clean Growth, one of four Grand Challenges identified in the UK Government's recent Industrial Strategy. The same group of partners will also provide significant input to the ReNU in the form of industrial supervision, training for doctoral candidates and supervisors, and access to facilities and equipment. Success in renewable energy and sustainable distributed energy fundamentally requires a whole systems approach as well as understanding of political, social and technical contexts. ReNU's doctoral training is thus naturally suited to a cohort approach in which cross-fertilisation of knowledge and ideas is necessary and embedded. The training programme also aims to address broader challenges facing wider society including unconscious bias training and outreach to address diversity issues in science, technology, engineering and mathematics subjects and industries. Furthermore, external professional accreditation will be sought for ReNU from the Institute of Physics, Royal Society of Chemistry and Institute of Engineering Technology, thus providing a starting point from which doctoral graduates will work towards "Chartered" status. The combination of an industry-driven doctoral training programme to meet identifiable market needs, strong industrial commitment through the provision of training, facilities and supervision, an established platform of research excellence in energy materials between the institutions and unique training opportunities that include internationalisation and professional accreditation, creates a transformative programme to drive forward UK innovation in renewable and sustainable distributed energy.

This project aims to understand how novel energy storage technologies might best be integrated into an evolving, lower-carbon UK energy system in the future. It will identify technical, environmental, public acceptability, economic and policy issues, and will propose solutions to overcome barriers to deployment. As electricity is increasingly generated by highly-variable renewables and relatively inflexible nuclear power stations, alternatives to the use of highly-flexible fossil-fuelled generation as a means of balancing the electricity system will become increasingly valuable. Numerous technologies for storing electricity are under development to meet this demand, and as the cost of storage is reduced through innovation, it is possible that they could have an important role in a low-carbon energy system. The Energy Storage Supergen Hub is producing a UK roadmap for energy storage that will be the starting point for this project. The value of grid-scale storage to the electricity system has been assessed for some scenarios. For extreme cases comprising only renewable and nuclear generation, the value is potentially substantial. However, the value of energy storage to the UK depends on the costs and benefits relative to sharing electricity imbalances through greater European interconnection, demand-side electricity response, and wider energy system storage, and the optimal approaches to integrating energy storage at different levels across the whole energy system are not well understood. This project will take a broader approach than existing projects by considering energy system scenarios in which storage options are more integrated across the whole energy system, using a series of soft-linked energy and electricity system models. Demand-side response and increased interconnection will be considered as counterfactual technologies that reduces the need for storage. Three broad hypotheses will be investigated in this project: (i) that a whole energy system approach to ES is necessary to fully understand how different technologies might contribute as innovation reduces costs and as the UK energy system evolves; (ii) that a range of technological, economic and social factors affect the value of ES, so should all be considered in energy system scenarios; and, (iii) that the economic value of the difference between good and bad policy decisions relating to the role of energy storage in the transition to low-carbon generation is in the order of £bns. A broader, multidisciplinary approach, which extends beyond the techno-economic methodologies that are adopted by most studies, will be used to fully assess the value of energy storage. This project will therefore also examine public acceptability issues for the first time, compare the environmental impacts of storage technologies using life-cycle analyses, and examine important economic issues surrounding market design to realise the value of storage services provided by consumers. All of these analyses will be underpinned by the development of technology-neutral metrics for ES technologies to inform the project modelling work and the wider scientific community. These multidisciplinary considerations will be combined in a series of integrated future scenarios for energy storage to identify no-regrets technologies. The project will conclude by examining the implications of these scenarios for UK Government policy, energy regulation and research priorities. The analyses will be technical only to the point of identifying the requirements for energy storage, with absolutely no bias towards or against any classes of storage technology.

Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

The objective of the Fellowship is to create a new platform to identify millions of streams of power flows in the large-scope distribution network to enable the ambitious blockchain technology for the power industry, which is seen as a future trend with a growing number of distributed energy resources. I believe that the eventual peer-to-peer (P2P) electricity market can only be realised when individual transactions can be physically traced to enhance the transparency and reflect the actual usage of the network for correct billing. This Fellowship questions the overlook of the present blockchain concept on the power grid infrastructure and proposes to analytically uncouple transactions from the usage of the physical medium for electricity transport. This Fellowship pushes the complex power systems (particularly distribution networks) analytics to its new limits by i) exploiting geographical information system with new distribution power flow tracing techniques with newly defined trait; ii) taking into account the mobility of distributed energy resources, e.g. electric vehicles, battery energy storage to flexible electricity trading from the physical constraint of the infrastructure; iii) using analytical, signal processing and chromatics methodology with smart metering data to improve power flow tracing performance especially for highly complicated distribution networks with microgrids and millions of nodes to represent all market participants; iv) developing a new tool as a fundamental layer of application programming interface to the future blockchain platform. The outcome of this Fellowship will not only shed light on the fundamental barriers on the energy P2P sharing economy but will also lead to the rollout of blockchain in the energy sector by enabling substantial public engagement to realise "Decarbonisation, Deregulation, Decentralisation" via "Transactions, Transparency, Traceability, Time-stamped, Trust".
