UK shipping produced 5.9 million tonnes of CO₂ equivalent from domestic routes and 13.8 million tonnes from international routes in 2017, together making up 3.4% of the UK’s total greenhouse gas emissions, while also pumping out nitrogen oxides, sulphur dioxide, and particulates that damage human health in coastal communities. The problem is that decarbonising maritime activity is not a one-size-fits-all fix. Each port has different vessels, cargoes, local infrastructure, and supply chains for alternative fuels. Current clean maritime plans focus on technologies already close to market (technology readiness levels 3–7), but deeper fundamental research across hydrodynamics, fuels, combustion, electric machines, batteries, fuel cells, energy systems, digitisation, logistics, and safety engineering is needed to reach zero-carbon by 2050. If this hub succeeds, it will produce targeted technical and socio-economic interventions tailored to specific UK ports and their surrounding communities. It will feed into a national clean maritime strategy with clear milestones for 2030, 2040, and 2050. A dedicated policy unit will supply quantitative evidence to regulators and lawmakers, while a network of regional hubs across England, Scotland, Wales, and Northern Ireland will spread best practice. The global market for maritime emission reduction technologies could reach $15 billion annually by 2050, offering substantial economic opportunity for the UK if the fundamental science and place-based solutions are delivered.

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.
