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 NHP-WEC project aims to advance data-driven monitoring and control in connection to both device technology and sea state predictions for WEC arrays. The research proposed is simultaneously generic while also significantly contributing to the development of an existing concept device that has shown potential, namely the multi-axis TALOS that has been developed and tank tested at Lancaster University (LU). TALOS is a novel multi-axis point absorber-style built as a 1/100th scale representation, with a solid outer hull containing all the moving parts (like a submarine or a PS Frog style WEC device). The internal PTO system is made up of an inertial mass with hydraulic cylinders that attach it to the hull. The mass makes up a significant proportion of the device, hence it moves around as the hull is pushed by various wave motions. The motion of the ball moves hydraulic cylinders causing them to pump hydraulic fluid through a circuit. The flow of this hydraulic fluid is used to turn a hydraulic motor, which is coupled to an electrical generator, to generate electricity i.e. an inertial mass PTO approach. Key strengths include: The arrangement of the rams allows for the mass ball to move in multiple directions, allowing energy to be captured from multiple degrees of freedom. The flow of hydraulic fluid will change as the ball's motion changes, so an internal hydraulic smoothing circuit is utilised to regulate the output. The latest design has proven to be successful in wave tank testing and the PTO system yields a smooth output in response to time-varying inputs from waves. An analytical model has also been developed to combine data from the hull model and hydraulic rig, yielding a predicted power output of up to 3.2 kW. However, TALOS is at a very early stage of development and requires further research to advance its Technology Readiness Level (TRL). The design, development, deployment and operation of WECs, such as TALOS and their potential commercial use requires a holistic understanding of the marine environment, including on-line monitoring to enhance control combined with prediction. Potential WEC deployment sites and energy resource from single devices and arrays must be determined. Operational conditions, including wave characteristics must be quantified to estimate dynamic loads on WEC, constraining manufacturing and their real-time operation. In this context, SmartWave, developed by the UoH, with the ORE Catapult and Orsted, is a tool capable of deriving high resolution sea state conditions from satellite images using machine learning. Key strengths: SmartWave is based on a novel forecasting methodology, capable of resolving sea state within offshore windfarms for sector O&M logistics. It integrates recent advances in all-weather satellite monitoring to map and study the temporal and spatial distribution of sea surface wave characteristics. However, existing limitations must be addressed to advance the TRL of WEC capabilities and hence fully exploit this new technology. For example, it has been developed to characterize significant wave height, whilst further research is essential in order to extract other sea state parameters, including wave height, direction and frequency. Nonetheless, since it is capable of global reach remotely, without the use of in situ sensors, SmartWave is uniquely placed to identify the selection of appropriate deployment sites depending on the device size and specification, for optimal production of electricity. The NHP-WEC project brings together key aspects of WEC technology and the global deployment potential of SmartWave, allowing integration of novel methodologies across optimisation, control, condition monitoring and resource forecasting. These advances will together drive evidenced reductions in costs and hence provide confidence on the benefits of wave energy technology to developers and investors.

Hydrogen and alternative liquid fuels have an essential role in the net zero transition by providing connectivity and flexibility across the energy system. Despite advancements in the field of hydrogen research both in the physical sciences and engineering, significant barriers remain to the scalable adoption of hydrogen and alternative liquid fuel technologies, and energy services, into the UK's local and national whole system infrastructure policy. These are technical barriers, organisational barriers, regulatory and societal barriers, and financial barriers. The vision as Co-ordinator of the Centre for Systems Integration of Hydrogen and Alternative Fuels (CSI-HALF) is to deliver a fundamental shift in critical analysis of the role of hydrogen in the context of the overall energy landscape, through the creation of robust tools which are investment-oriented in their analysis. A Whole Systems and Energy Systems Integration approach is needed here, in order to better understand the interconnected and interdependent nature of complex energy systems from a technical, social, environmental and economic perspective. This 6-month proposal is to deliver key stakeholder engagement, to develop a comprehensive, co-created research programme for the Centre. The Centre is led by Prof Sara Walker, currently Director of the EPSRC National Centre for Energy Systems Integration, supported by Prof David Flynn of Heriot Watt University and Prof Jianzhong Wu of Cardiff University. The team have extensive experience of large energy research projects and strong networks of stakeholders across England, Wales and Scotland. They bring to the Centre major hydrogen demonstrators through support from partners involved in InTEGReL in Gateshead, ReFLEX in Orkney, and FLEXIS Demonstration in South Wales for example. This 6-month phase is an engagement exercise. It is our responsibility to engage with the community in a manner which respects and supports their motivations. Our philosophy in undertaking this engagement work is based around principles of inclusion, authenticity and tailoring. We will de-risk the integration of HALF into the UK energy system, through full representation of the hydrogen spectrum with open and integrated analysis of top-down and ground-up perspectives, including representation of the immediate and wider stakeholder group e.g. financial markets. We shall engage with this broad section of stakeholders with the support of experts in citizen and community engagement. These expert partners will enable us to produce the highest possible quality of engagement in the 6-month period. Our initial approaches to key stakeholders have been extremely positive. We have already engaged with, and have support from representatives of: pink, green and blue hydrogen production; hydrogen transportation stakeholders; hydrogen end users; policy makers and community groups; financial and consultation organisations; and key academics. We shall engage to create a vibrant, diverse, and open community that has a deeper understanding of whole systems approaches and the role of hydrogen and alternative liquid fuels (HALF) within that. We shall do so in a way which embeds EDI in the approach. We shall do so in a way which is a hybrid of virtual and in-person field work consultation, and develop appropriate digital tools for engagement. This builds on accredited practices and inclusive key performance indicators. The network created as a result of the engagement activity will be consulted on with respect to key research questions for the Centre, to co-create a research programme. Through relationship building, webinars and focus groups, we shall deliver an expertise map for hydrogen integration, an information pack containing the state of the art "commons", and a full proposal with comprehensive research programme which has extensive community buy-in.

The global hydrogen generation market is valued at $115.25 billion in 2017 and is projected to grow to $154.74 billion by 2022 [Global Outlook & Trends for Hydrogen, IEA, 2017]. We are witnessing significant market opportunities emerging for hydrogen technologies today. New and existing hydrogen technology developments and market activities are projected to intensify over the coming decade. Sustainable hydrogen solutions are a key pathway for decarbonising transport, heat and power generation sectors. Common challenges to sustainable hydrogen being adopted across these sectors are: - Cost reduction - Safety - Systems level and multisectoral innovations - Managing change Over the next decade innovative solutions are needed to tackle the above challenges, but it will be impossible without a dedicated mechanism to train doctoral Energy Innovation Leaders. These leaders should have a firm grasp of the technology from scientific fundamentals through to applied engineering and a solid understanding of the techno-economic barriers and an appreciation of the societal issues that will impact on the translation of disruptive technologies from research labs through to market. This goes beyond being multidisciplinary, but is a transdisciplinary training, reflecting the translation steps from understanding market driven needs, planning and conducting appropriate basic and applied research to products/solutions/system development through to successful market penetration. This is delivered by a cohort training approach through the cross fertilisation of ideas of a cohort with a diverse background, peer-demonstration of the value of research across a diverse range of stakeholder-led projects, thus facilitating a peer-to-peer transdisciplinary learning culture. The SusHy Consortium, led by Gavin Walker, continues a long running and highly successful collaboration in hydrogen research between the Universities of Nottingham, Loughborough, and Birmingham (UoN, LU, UoB) which started over a decade ago with the Midlands Energy Consortium. The Midlands Energy Graduate School spawned two successful CDTs (Hydrogen, Fuel Cells and their Applications and the current Fuel Cells and their Fuels). The current proposal for a CDT in Sustainable Hydrogen brings together the world leading expertise in hydrogen generation, purification, sensors/monitoring, and storage, along with whole systems issues (resilience engineering, business economic models and life cycle analysis) which exist across the three Universities. A gap in the consortium expertise is in the research field of hydrogen safety and we identified the internationally-renowned Hydrogen Safety Engineering and Research Centre (HySAFER) at Ulster University (UU) as the right partner to deliver on this key aspect. This is the first broad collaboration in the world seeking to investigate, train researchers and produce leaders in Sustainable Hydrogen. Stakeholder Partnerships. A key strength of this CDT is the active involvement of the Stakeholders in co-creation of the training programme which is reciprocated in the value with which the Stakeholders view of the CDT. This shared vision of a training partnership between the Universities and Stakeholders will lead to the smooth function of the CDT with not just a high-quality training programme, but a programme that is tailored to the sector needs for high-quality, industry-ready doctoral Energy Innovation Leaders. The valued CDT-stakeholder partnership will also be a significant appeal to candidates interested in energy-related PhDs and will be used to help market the CDT programme to a diverse talent pool.

Identifying and understanding extreme and fatigue loads on tidal energy converters (TEC), understanding environmental extremes (other than main resource), and determining accessibility, serviceability criteria, fault intervals and associated device life cycles, are all important factors that can determine CAPEX and OPEX cost of devices and array deployments. This project will provide a holistic vision for design optimisation to ensure, reliability and survivability for floating TECs (FTECs). Computational modeling and real sea deployment measurements will provide a tool to inform the optimum operational strategy and maximise survivability and reliability for FTEC devices and arrays. Swansea University will develop a versatile BEMT code to enable the study of FTECs numerically at a fundamental level and physically by working closely with project partners Oceanflow Energy, EMEC and Black and Veatch to determine the most important parameters to be measured for this type of technologies. Measurements taken at the Sanda Sound deployment site for the Oceanflow Energy 1:4 scale EVOPOD prototype, including loads on the device and sea condition datasets, will be used to validate the BEMT model for FTECs. A generic BEMT FTEC model will then be tested using environmental data, including extremes, provided by EMEC. In collaboration with Black and Veatch the resulting load predictions will be used to estimate component fatigue and failure. This will lead to the development of an operational strategy and design guidance to maximise survivability and reliability of FTECs.
