The EPSRC CDT in Net Zero Aviation in partnership with Industry will collaboratively train the innovators and researchers needed to find the novel, disruptive solutions to decarbonise aviation and deliver the UK's Jet Zero and ATI's Destination Zero strategies. The CDT will also establish the UK as an international hub for technology, innovation and education for Net Zero Aviation, attracting foreign and domestic investment as well as strengthening the position of existing UK companies. The CDT in Net Zero Aviation is fully aligned with and will directly contribute to EPSRC's "Frontiers in Engineering and Technology" and "Engineering Net Zero" priority areas. The resulting skills, knowledge, methods and tools will be decisive in selecting, integrating, evaluating, maturing and de-risking the technologies required to decarbonise aviation. A systems engineering approach will be developed and delivered in close collaboration with industry to successfully integrate theoretical, computational and experimental methods while forging cross theme collaborations that combine science, technology and engineering solutions with environmental and socio-economic aspects. Decarbonising aviation can bring major opportunities for new business models and services that also requires a new policy and legislative frameworks. A tailored, aviation focused training programme addressing commercialisation and route to market for the Net Zero technologies, operations and infrastructure will be delivered increasing transport and employment sustainability and accessibility while improving transport connectivity and resilience. Over the next decade innovative solutions are needed to tackle the decarbonisation challenges. This can be only achieved by training doctoral Innovation and Research Leaders in Net Zero Aviation, able to grasp the technology from scientific fundamentals through to applied engineering while understanding the associated science, economics and social factors as well as aviation's unique operational realities, business practices and needs. Capturing the interdependencies and interactions of these disciplines a transdisciplinary programme is offered. These ambitious targets can only be realised through a cohort-based approach and a consortium involving the most suitable partners. Under the guidance of the consortium's leadership team, students will develop the required ethos and skills to bridge traditional disciplinary boundaries and provide innovative and collaborative solutions. Peer to peer learning and exposure to an appropriate mix of disciplines and specialities will provide the opportunity for individuals and interdisciplinary teams to collaborate with each other and ensure that the graduates of the CDT will be able to continually explore and further develop opportunities within, as well as outside, their selected area of research. Societal aspects that include public engagement, awareness, acceptance and influencing consumer behaviour will be at the heart of the training, research and outreach activities of the CDT. Integration of such multidisciplinary topics requires long term thinking and awareness of "global" issues that go beyond discipline and application specific solutions. As such the following transdisciplinary Training and Research Themes will be covered: 1. Aviation Zero emission technologies: sustainable aviation fuels, hydrogen and electrification 2. Ultra-efficient future aircraft, propulsion systems, aerodynamic and structural synergies 3. Aerospace materials & manufacturing, circular economy and sustainable life cycle 4. Green Aviation Operations and Infrastructure 5. Cross cutting disciplines: Commercialisation, Social, Economic and Environmental aspects 75 students across the UK, from diverse backgrounds and communities will be recruited.

Along the well-to-wake value chain from upstream processes associated with fuels production and supply, components manufacture, and ships construction to the operation of ports and vessels, the UK domestic and international shipping produced 5.9 Mt CO2eq and 13.8 Mt CO2eq, respectively in 2017, totalling 3.4% of the UK's overall greenhouse gas emissions. The sector contributes significantly to air pollution challenges with emissions of nitrogen oxide, sulphur dioxide and particulate matters, harming human health and the environment particularly in coastal areas. The annual global market for maritime emission reduction technologies could reach $15 billion by 2050. This provides substantial economic opportunities for the UK. The Department for Transport's Clean Maritime Plan provides a route map for action on infrastructure, economics, regulation, and innovation that covers high technology readiness level (TRL 3-7). There is a genuine opportunity to explore fundamental research and go beyond conventional marine engineering and naval architecture and exploit the UK's world-leading cross-sectoral fundamental research expertise on hydrodynamics, fuels, combustion, electric machines and power electronics, batteries and fuel cells, energy systems, digitization, management, finance, logistics, safety engineering, etc. The proposed UK-MaRes Hub is a multidisciplinary research consortium and will conduct interdisciplinary research focussed on delivering disruptive solutions which have tangible potential to transform existing practice and reach a zero-carbon future by 2050. The challenges faced by UK maritime activity and their solutions are generally common but when deployed locally, they are bespoke due to the specifics of the port, the vessels they support, and the dependencies on their supply chains. Implementation will be heavily dependent on the local community, existing infrastructure, as well as opportunities and constraints related to the supply, distribution, storage and bunkering of alternative fuels, in decarbonising port handling facilities and cold-ironing, with the integration of renewable energy, reducing air pollution, to land-use and increased capacity and capability, and the local development of skills. The types of vessels and the cargoes handled through UK ports varies and are related to several factors, such as geographical location, regional industrial and business activity and wider transport links. Therefore, UK-MaRes Hub aims to feed into a clean maritime strategy that can adapt to place-based challenges and provide targeted technical and socio-economic interventions through a novel Co-innovation Methodology. This will bring together Research Exploration themes/work packages and Responsive Research Fund project activity into focus on port-centric scenarios and assess possibilities to innovate and reduce greenhouse gas emissions by 2030, 2040 and 2050 timeframes, sharing best practice across the whole maritime ecosystem. A diverse, and inclusive Clean Maritime Network+ will ensure wider dissemination and knowledge take-up to achieve greater impact across UK ports and other maritime activity. The Network+ will have coordinated regional activity in South-West, Southern, London, Yorkshire & Lincolnshire, Midlands, North-West, North-East, Scotland, Wales, and Northern Ireland. An already established Clean Maritime Research Partnership has vibrant academic, industrial, and civic stakeholder members from across the UK. UK-MaRes Hub will establish a Clean Maritime Policy Unit to provide expert advice and quantitative evidence to enable rapid decarbonisation of the maritime sector. It will ensure that the UK-MaRes Hub is engaging with policymakers at all stages of the hub activities.
