The vision for the EDI+ network is to acknowledge and address key challenges and equip a cohort of researchers and their organisations to make lasting changes towards a diverse, equitable, inclusive and accessible research community. This will have impact beyond the academy and set a precedent, offering the means to tailor EDI action among the diverse organisations participating in energy research. It garners the best of scientific and social science evidence and critical approaches from the humanities to put EDI challenges in appropriate perspectives and make them available for action. It is action-oriented and based on an effective Theory of Change Model that considers: -> the desired outcomes (aims) for the network (An energy research community that is equal, inclusive and diverse) -> the evidence-informed assumptions for achieving the outcomes (such as findings from the Inclusion Matters programme) -> the activities that, based on the assumptions, should be implemented to achieve the aims (prioritising time, training and support for action) Evidence suggests that key barriers to effective change in EDI can be condensed to be: - Lack of Time to develop deep, evidence-based understanding of local issues - Lack of Access to the power structures required to enact change - Lack of resource and evidence-based solutions to issues that are found - Isolation from peers with experience of EDI driven change In response, we propose a fellowship programme, which recruits EDI champions from diverse energy research institutions; trains them in EDI issues; research methods for analysing organisational contexts, how to make organisational changes, and how to implement and evaluate plans of action; and supports them to publish their results. All fellows will have the support of a named senior executive of their organisation, all of whom will engage in cross-institutional reciprocal mentoring to embed learning and change in the institutional context. We name these 'fellowships' (despite the possible connotations of the term 'fellow') so that they will have prestige on the participants' cv's, emphasise the research-basis of the actions, and lend weight to their change-making activities under the network. The 'fellows' will form a mutually supportive network that should endure beyond the life of the funding scheme. EPSRC funded fellows will be complemented by industry- and government- funded fellows to expand the network beyond the funded call, and with the establishment of an alumni network, will offer the potential for the network to endure beyond the funding period. Selected training events will be open to the wider energy research community, who will also have access to a toolkit on EDI actions in context and all other network publications. Additional impact activities will include workshops and presentations to coincide with existing conference and research events, to maximise the reach of the network. Findings will be shared and promoted through a 'network of networks' approach across the energy research community nationally, and internationally.

By 2050 it's estimated >400 GW of energy will be gathered by offshore wind across the whole North Sea. For scale, Hinkley Point C nuclear reactor is projected to produce 3.2 GW. How will this increased anthropogenic use of our coastal seas impact already stressed marine ecosystems? And how will that same production of renewable energy offset risks of extreme climate change that, left unchecked, will increase the risk of biodiversity declines. There are many complex changes to ecosystems linked to Offshore Wind Farms (OWFs) that we need to understand now, so that the extent of increasing wind energy extraction further offshore is managed in the most sustainable way. An important effect of large wind energy extraction will be to reduce the amount of energy that would normally go into local ocean currents via surface stress, altering sea state and mixing. Conversely, there will be local increases in turbulence around turbine structures and seabed scouring near fixed foundations. Any change in ocean mixing may change the timing, distribution and diversity of phytoplankton primary production, the base of the food chain for marine ecosystems, to some degree. This has knock-on-effects on the diversity, health and locations of pelagic fish that are critical prey species of commercial fish, seabirds and marine mammals. Observed changes caused by operational OWFs in the southern North Sea include local surface temperature rise and the displacement of seabirds and fishing fleets from the OWF footprint, whereas seals often appear to be feeding near turbines. All of these changes have a linked component - important prey fish species - which are likely to aggregate near structures (as seen at other offshore platforms). Seabirds and fishing fleets subsequently have less space to hunt, with potentially increased competition for fish. However, if OWFs are also de facto marine protected areas and so positively affect local primary production, they may provide good habitat for fish population growth. So, what are the cumulative effects of current OWF developments and the thousands of additional planned structures? Do the physical, biogeochemical and ecosystem changes exacerbate or mitigate those resulting from climate change? As OWFs migrate further offshore as floating structures, how can current knowledge based on shallow, coastal fixed turbines be suitably extrapolated to understand the impacts on ecosystems dependent on seasonal cycles that are typical of deeper waters? PELAgIO will address all of these questions through an interdisciplinary, multi-scale observation and modelling framework that spans physical mixing through to plankton production, on to the response of fish and whole ecosystems. We will collect fine-scale data using the latest multi-instrumented acoustic platforms set beside and away from OWFs, complemented by autonomous surface and submarine robots to capture continuous and coincident data from physics to fish, over multiple scales and seasons to fully understand what is 'different' inside an OWF and how big its footprint is. These new data will test the effects on seabirds and marine mammals to build an OWF ecosystem parameterization that accounts for changes to mixing and wind deficit impacts, and is scalable to next-generation OWFs. This bottom-up, comprehensive approach will enable true calibration and validation of 3D ocean-biogeochemical-sediment modelling systems, from the scale of turbine foundations up to the regional and even cross-shelf scales. Identified changes will be integrated into Bayesian ecosystem models that enable the cumulative effects of ecological, social and economic trade-offs of different policy approaches for OWFs to be quantifiably assessed for present day conditions, during extreme events and under climate change.

The Government's commitment to increasing offshore and marine renewable energy generation presents significant technological challenges in designing, commissioning and building the infrastructure, connecting offshore generation to onshore usage, and considering where these new developments are best placed, whilst balancing the impact they have upon the environment. In tandem, this commitment presents opportunities to advance UK capabilities in cutting-edge engineering and technologies in pursuit of net zero. Liverpool is home to one of the largest concentrations of offshore wind turbines globally in Liverpool Bay, the second largest tidal range in the UK, some of the largest names of maritime engineering alongside numerous SMEs, and the Port of Liverpool, a Freeport and Investment Zone status. The latest Science and Innovation Audit (2022) highlights Net Zero and Maritime as an emerging regional capability, and is an area in which the Liverpool City Region Combined Authority has stated its ambition to grow an innovation cluster. The University of Liverpool and Liverpool John Moores University each host world-class research expertise, environments and facilities relevant to addressing these maritime energy challenges, and have an established, shared track record in collaboration with industrial and civic partners. The Centre for Doctoral Training in Net Zero Maritime Energy Solutions (N0MES CDT) will play a vital role in filling critical skills gaps by delivering 52 highly trained researchers (PGRs), skilled in the identification, understanding, assessment, and solutions-delivery of pressing challenges in maritime energy. N0MES PGRs will pursue new, engineering-centred, interdisciplinary research to address four vital net zero challenges currently facing the North West, the UK and beyond: (a) Energy generation using maritime-based renewable energy (e.g. offshore wind, tidal, wave, floating solar, hydrogen, CCS) (b) Distributing energy from offshore to onshore, including port- and hinterland-side impacts and opportunities (c) Addressing the short- and long-term environmental impacts of offshore and maritime environment renewable energy generation, distribution and storage (d) Decommissioning and lifetime extension of existing energy and facilities The N0MES CDT will empower its graduates to communicate, research and innovate across disciplines, and will develop flexible leaders who can move between projects and disciplines as employer priorities and scientific imperatives evolve.

The pace of deployment of offshore wind (OW) energy is rapidly accelerating to power the transition to net zero. The UK government aims to increase from the current 14GW of offshore wind to at least 50GW by 2030, requiring c£17bn investment per year, then 120-170GW by 2050, to provide clean energy resilience. Despite the remarkable success of OW over the past decade, making it a central component of the UK energy mix, future growth brings new challenges. Deployment must now expand beyond the relatively benign, shallow waters of the southern North Sea to sites further from shore, a fundamentally different engineering, operating and natural environment. In such areas the two-way effects of new OW engineering on the marine biosphere and concomitant impact on other sea users are poorly understood. Beyond technical challenges, a major barrier to rapid deployment is consenting time. The Government aim to reduce typical consent time from 4 years to 1 year by 2030 is only achievable if new approaches to data collection, aggregation and modelling are validated and adopted. The volume and speed of deployment must increase 6-fold, while remaining commercially competitive, requiring industrialisation of manufacturing and installation while ensuring that materials (such as rare earth metals, copper, composites) and other resources (including energy) are used sustainably. The OW workforce will reach >100,000 direct and indirect jobs by 2030, with >8,000 projected at HE Level 7+. To achieve and sustain this, the workforce must be drawn from a diverse talent pool and be built on equitable, inclusive cultures where safety and wellbeing are central. The sector OW Industry Council (OWIC) recognises that increasing growth, and UK supply chain content, requires a highly skilled and resilient workforce and highlights the key role of CDT programmes in providing this. The previous EPSRC-NERC Aura CDT in Offshore Wind Energy and the Environment (Aura CDT I) successfully demonstrated the value of OW research and training at the interface of engineering and environmental sciences. Sustainable sector growth now requires further research that integrates emergent social, societal and economic challenges of OW energy. Thus, the proposed UKRI Centre for Doctoral Training in Offshore Wind Energy Sustainability and Resilience (Aura CDT II), provides integrated solutions across the EPSRC/NERC/ESRC remit. These transdisciplinary sector needs are co-identified by key sector stakeholders, including Aura CDT project partners OWIC, ORE Catapult, The Crown Estate, Renewable UK and DEFRA. Direct industry engagement has co-created five Aura CDT II challenge-based themes to: push the frontiers of offshore wind technology; accelerate consent and support environmental sustainability; achieve a sustainable wind farm life cycle; build and support a sustainable workforce; and develop a resilient net-zero energy system. The importance of these themes to the sector is demonstrated by the cash and in-kind support of >40 project partners, allowing us to support >75 CDT students. The CDT connects the University of Hull with partner Universities Sheffield, Durham and Loughborough. PL Dorrell (Director of Aura CDT I) is supported by nine CLs from the partner universities and a pool of >100 diverse supervisors bringing world leading expertise in the areas of engineering, environment and social sciences required to support the training and research elements. Both full and part time students will receive postgraduate training delivered collaboratively through an intensive 6-month multidisciplinary programme at Hull and subsequent courses, with all partners, addressing topics including leadership, public engagement, responsible innovation and EDIW. Small clusters of doctoral students will link expertise from across the four universities and industry partners to provide holistic insights into sector challenges while building cross-cohort collaboration and multiplying impacts.

There is a compelling need for well-trained future UK leaders in, the rapidly growing, Offshore Wind (OSW) Energy sector, whose skills extend across boundaries of engineering and environmental sciences. The Aura CDT proposed here unites world-leading expertise and facilities in offshore wind (OSW) engineering and the environment via academic partnerships and links to industry knowledge of key real-world challenges. The CDT will build a unique PhD cohort programme that forges interdisciplinary collaboration between key UK academic institutions, and the major global industry players and will deliver an integrated research programme, tailored to the industry need, that maximises industrial and academic impact across the OSW sector. The most significant OSW industry cluster operates along the coast of north-east England, centred on the Humber Estuary, where Aura is based. The Humber 'Energy Estuary' is located at the centre of ~90% of all UK OSW projects currently in development. Recent estimates suggest that to meet national energy targets, developers need >4,000 offshore wind turbines, worth £120 billion, within 100 km of the Humber. Location, combined with existing infrastructure, has led the OSW industry to invest in the Humber at a transformative scale. This includes: (1) £315M investment by Siemens and ABP in an OSW turbine blade manufacturing plant, and logistics hub, at Greenport Hull, creating over 1,000 direct jobs; (2) £40M in infrastructure in Grimsby, part of a £6BN ongoing investment in the Humber, supporting Orsted, Eon, Centrica, Siemens-Gamesa and MHI Vestas; (3) The £450M Able Marine Energy Park, a bespoke port facility focused on the operations and maintenance of OSW; and (4) Significant growth in local and regional supply chain companies. The Aura cluster (www.aurawindenergy.com) has the critical mass needed to deliver a multidisciplinary CDT on OSW research and innovation, and train future OSW sector leaders effectively. It is led by the University of Hull, in collaboration with the Universities of Durham, Newcastle and Sheffield. Aura has already forged major collaborations between academia and industry (e.g. Siemens-Gamesa Renewable Energy and Orsted). Core members also include the Offshore Renewable Energy Catapult (OREC) and the National Oceanography Centre (NOC), who respectively are the UK government bodies that directly support innovation in the OSW sector and the development of novel marine environment technology and science. The Aura CDT will develop future leaders with urgently needed skills that span Engineering (EPSRC) and Environmental (NERC) Sciences, whose research plays a key role in solving major OSW challenges. Our vision is to ensure the UK capitalises on a world-leading position in offshore wind energy. The CDT will involve 5 annual cohorts of at least 14 students, supported by EPSRC/NERC and the Universities of Hull, Durham, Newcastle and Sheffield, and by industry. In Year 1, the CDT provides students, recruited from disparate backgrounds, with a consistent foundation of learning in OSW and the Environment, after which they will be awarded a University of Hull PG Diploma in Wind Energy. The Hull PG Diploma consists of 6 x 20 credit modules. In Year 1, Trimester 1, three core modules, adapted from current Hull MSc courses and supported by academics across the partner-institutes, will cover: i) an introduction to OSW, with industry guest lectures; ii) a core skills module, in data analysis and visualization; and iii) an industry-directed group research project that utilises resources and supervisors across the Aura partner institutes and industry partners. In Year 1, Trimester 2, Aura students will specialise further in OSW via 3 modules chosen from >24 relevant Hull MSc level courses. This first year at Hull will be followed in Years 2-4 by a PhD by research at one of the partner institutions, together with a range of continued cohort development and training.
