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 UK is facing an energy crisis on three fronts: climate change, energy security, and affordability. This challenge requires a fundamental change in our society, to enable a deep energy demand reduction and wide use of low-carbon technologies, supported by policy, businesses and the public alike. Energy demand reduction is in fact fundamental so that we can improve energy security, reduce household energy bills and address climate change. Research has shown that reducing energy use could help meet half of the required emissions reductions we need by 2050 to become a Net Zero society. While this poses a challenge, it also provides an opportunity for the UK to become a global leader in energy demand reduction, and associated research. The Energy Demand Research Centre (EDRC) develops the next phase of energy demand research in the UK, building on previous research and working closely with academic and non-academic partners. Our work will inform and inspire energy demand reductions that support an affordable, comfortable and secure Net Zero society. Our research programme cuts across different sciences (e.g. engineering and social) and sectors (e.g. buildings, transport and industry). We study which energy demand solutions can be delivered in a flexible and equitable manner and at which locations, taking into consideration issues such as local housing stock and transport links, skills base and governance models. We aim to deliver impactful research on energy demand that produces actionable solutions for industry, policy makers, practitioners and charities.

The ESPRC Centre for Doctoral Training in Renewable Energy Northeast Universities Plus (ReNU+) is a transformative programme that will train a new generation of Doctoral Carbon Champions (DCCs) who are characterised by scientific and engineering excellence and capable of interdisciplinary systemic thinking to accelerate Net Zero. The outcome from ReNU+ will be that DCCs will meet critical needs in high-skill employment across industry, policy, education and government and convert key challenges in resilience and equity into economic opportunities for the United Kingdom. This will be achieved through a professionally accredited training programme in a thriving environment of research excellence led by Northumbria, Newcastle and Durham universities. The 2023-2035 energy landscape sets a compelling context for ReNU+ and in particular, the need for future leaders in this space in the United Kingdom. Locally generated renewable energy will provide the UK with increased energy security and critically important additions in electricity capacity to meet domestic and industrial demands. This is only one piece of the landscape however, which also includes sustainability (e.g. critical materials supply), resilience (e.g. climate change mitigation) and an equitable transition to Net Zero, which offers both economic and health benefits. The absorptive capacity for ReNU+ DCCs is partly evidenced by the forecast of 694,000 new UK jobs in the low carbon and renewable energy economy by 2030 (source: UK Local Government Association). The ReNU+ training programme has a core focus on developing key skills that facilitate understanding of and engagement with the wider Net Zero system including investment, regulation and end-user engagement. It will become a reference for high-skill training in Net Zero that redefines the role of scientists and engineers as critical catalysts for decarbonisation who deliver impact well beyond technology. ReNU+ identifies a critical link between equality, diversity and inclusivity and decarbonisation and includes key innovations to leverage this link. Consequently, DCCs will also develop societal and citizenship values as they become living examples of the future workforces to enable an equitable and sustainable transition to Net Zero. This approach has been validated by our partners who have co-designed and will co-deliver the ReNU+ training programme. This support includes national and local Government, multinational companies, small-to-medium enterprises and charity organisations.

Hydrogen and alternative liquid fuels (HALF) 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. These are technical barriers, organisational barriers, regulatory and societal barriers, and financial barriers. There are, therefore, significant gaps between current levels of hydrogen production, transportation, storage, conversion, and usage, and the estimated requirement for achieving net-zero by 2050. To address this, our proposed research programme has four interlinked work packages. WP1 will develop forward-thinking HALF technology roadmaps. We will assess supply chain availability and security. Selected representative HALF use cases will be used to identify and quantify any opportunities, risks and dependencies within a whole systems analysis. We will also develop an overarching roadmap for HALF system integration in order to inform technology advancement, industry and business development, as well as policy making and social interventions. WP2 will improve HALF characterisation and explore urgent new perspectives on the energy transition, including those related to ensuring resilience and security while also achieving net-zero. We will contrast the energy transition delivered by real incentives/behaviour versus those projected by widely-used optimisation models. The WP provides the whole systems modelling engine of the HI-ACT Hub, with a diverse array of state-of-the-art tools to explore HALF integration. WP 3 will explore the vital coupling of data and information relating to whole system planning and operational decision support, through the creation of a cyber physical architecture (CPA). This will generate new learning on current and future opportunities and risks, from a data and information perspective, which will lead to a whole system ontology for accelerated integration of hydrogen technologies. WP 4 considers options for a future energy system with HALF from a number of perspectives. The first is to consider expert views on HALF energy futures, and the public perceptions of those views. The second perspective considers place-based options for social benefit in HALF energy futures. The third perspective is to consider regulatory and policy options which would better enable HALF futures. Embedded across the research programme is the intent to create 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. The Hub is led by Prof Sara Walker, Director of the EPSRC National Centre for Energy Systems Integration, supported by a team of 16 academics at a range of career stages. The team have extensive experience of large energy research projects and strong networks of stakeholders across England, Wales, Scotland and Northern Ireland. They bring to the Hub major hydrogen demonstrators through support from partners involved in InTEGReL in Gateshead, ReFLEX in Orkney, and FLEXIS Demonstration in South Wales for example. 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 within that.
