Energy supply for the UK, and for the World as a whole, will experience major changes during the next 20 years, as states seek secure energy supplies, combined with low costs, and sustainable environmental impacts. Most of world energy currently derives from combustion of fossil fuel. The UK is no exception.In the UK, fossil fuel (oil) dominates transport use, and this is unlikely to change in the near future. Electricity and heat generation is dominated by gas (41%) and coal (34%), with 20% from nuclear, only 3% from renewables, and 2% imported electricity. This gas and coal will from now onwards largely be imported, paying costs to suppliers outside the UK. This also means security of supply is not guaranteed. Can improvements be made to the use of these energy sources?A key environmental problem is that fossil fuel combustion releases CO2 to the atmosphere. This is now, beyond reasonable doubt, linked to global warming and climate change. Atmospheric CO2 also dissolves in ocean water, forcing an increased acidity greater than any time in the past 20 Million years. Even those who still do not believe in climate change cannot escape the inevitability of ocean acidification / with as yet un-predicted consequences. For this reason alone, atmospheric CO2 must be reduced.To enable continued use of fossil fuels it is an urgent requirement to de-carbonise their combustion. The Stern Review of Climate Change Economics in 2006 clearly re-stated that significant progress must be made during the ten years until 2017.This research proposal addresses the fossil fuel issues in two ways: Firstly, to create a UK Centre of university expertise in the capture of CO2 from power plants. Current industrial systems rely on chemical absorption by solvents, but require a very high energy input, which reduces the environmental gain. The Centre will focus on new technologies of CO2 separation by adsorption onto nanoporous materials, by filtration of CO2 from power plant flue gases by semi-permeable membranes, and by membrane and adsorption separation processes for the production of oxygen from air, to enable oxy-fuel combustion and efficient CO2 separation.Secondly, we acknowledge that there is, and will be, a need to remove existing CO2 emissions from the atmosphere. The reductions proposed from power plant emissions do not reduce existing CO2, but rather just make the increase slower. To control the earth atmosphere and produce a sustainable climate requires extraction of CO2 already emitted. This is routinely achieved, at low cost, by vegetation. We will create an entirely new centre of university expertise which will focus on using bio-mass from agriculture, forestry and waste. This can firstly make bio-fuel to replace fossil sources, and the residues can be pyrolised to form charcoal. Such charcoal has been used in traditional cultures to enhance soil fertility, and locks up carbon for thousands of years. Improvements in land use in the EU, the USA, and developing world can achieve this, by an integration of engineering, soil science, and social benefit to cultivators.Edinburgh (with the British Geological Survey and Heriot-Watt) already hosts the UK's largest academic centre investigating geological burial of captured CO2. There are existing multi-skilled networks at Edinburgh linking land use, agriculture, social, legal and economic analysis, chemical engineering and petroleum geoscience. Creation of the Carbon Capture Centre will be an ideal complementary activity, and the range of expertise, from atmospheric capture, to power-plant capture to cultivation and geological burial will be unique.Outputs from the Centre can help the UK to combust coal and gas with environmentally clean methods, to enhance energy security by diversifying away from fossil fuel sources, and to commence the direct clean-up of CO2 from the atmosphere in an energy and financially efficient, sustainable way.

Infrastructure is fundamental to our economy and society, e.g. being one of the 10 pillars of the recently launched UK Industrial Strategy. Long linear (geotechnical) assets (LLAs) are a major component of this infrastructure and fundamental to the delivery of critical services over long distances (e.g. road & railway slopes, pipeline bedding, flood protection structures). Central government infrastructure investment will rise by almost 60% to £22 billion p.a. by 2022 (ONS). This will support both the development of new infrastructure, and the repair of existing infrastructure. At present, there are 10,200 km of flood defences in Great Britain; 80,000 km of highways; 15,800 km of railway). Failure of these assets is common-place (e.g. in 2015 there were 143 earthworks failures on Network Rail - >2 per week), the resulting cost of failure is high (e.g. for Network Rail, emergency repairs cost 10 times planned works, which cost 10 times maintenance), and vulnerability to these failures is significant (748,000 properties with at least a 1-in-100 annual chance of flooding; derailment from slope failure is the greatest infrastructure-related risk faced by our railways). However, the exact reasons for - and timing of - failure is, at present, poorly understood. This leads to unanticipated failures that cause severe disruption and damage to reputation. Current approaches to design and asset management perpetuate this situation as they are based on past experience, which cannot be extrapolated to future performance: the infrastructure is older, ever more intensively used and subject to increasingly extreme weather patterns. Together, these factors significantly increase the likelihood of failures in the future causing reduced performance and poorer service. Climate change has been identified as one of the factors driving this change. There is an exciting opportunity to bring together new advances in research and technology with design and asset management practices from different LLAs to reduce the risks posed to infrastructure systems by deterioration and future change. Current techniques can estimate future rates of deterioration that might lead to failure in transport infrastructure slopes, but are difficult to scale up, do not capture all drivers of deterioration relevant to all LLAs, are poor at dealing with uncertainty and heterogeneity, and lack rigorous validation against representative field data. Different asset owners have access to vast quantities of failure and condition data from their networks (recently enabled by technological advances in data capture and storage) but use different approaches to address failure based on historical data. ACHILLES proposes a research programme that brings these approaches together, coupled with statistical advances to enable rigorous use of network data, and economics to assess the value of design, monitoring and mitigation options. Our long-term vision is for the UK's infrastructure to deliver consistent, affordable and safe services, underpinned by intelligent design, management and maintenance. ACHILLES proposes a Programme to address this challenge by combining laboratory/field experimentation, numerical modelling and simulation, statistical data and cost benefit analysis, and activities to enable its outcomes to be adopted by LLA owners/operators: Deeper understanding of material and asset deterioration and how to model and predict New design tools to account for deterioration; and assessment tools to characterise Strategies to mitigate deterioration from material to asset scale Decision-making framework to prioritise spending on design, monitoring and/or interventions that accounts for heterogeneity and uncertainty, and informs appropriate business cases Better understanding of the importance of characterising heterogeneity and uncertainty for infrastructure decision making processes Knowledge and tools to incorporate data analytics into asset assessment and monitoring

The focus of this collaboration is to link research groups who undertake full-scale monitoring of slopes through a range of people-based activities. These include: visits of UK researchers and academics to a number of field sites both in the UK and overseas; exchanges of young researchers between UK and overseas academic institutions; secondments of researchers to industry; a dissemination workshop and the establishment of a web portal for the storage and exchange of data and for the running of on-line meetings and seminars. Despite its main focus, the collaboration will necessarily provide links between members of the extended research teams with expertise in numerical simulation, constitutive modelling, soils testing and instrumentation. It is the intention that these activities will also be linked within the wider collaborative framework created by this funding.

National infrastructure (NI) systems (energy, transport, water, waste and ICT) in the UK and in advanced economies globally face serious challenges. The 2009 Council for Science and Technology (CST) report on NI in the UK identified significant vulnerabilities, capacity limitations and a number of NI components nearing the end of their useful life. It also highlighted serious fragmentation in the arrangements for infrastructure provision in the UK. There is an urgent need to reduce carbon emissions from infrastructure, to respond to future demographic, social and lifestyle changes and to build resilience to intensifying impacts of climate change. If this process of transforming NI is to take place efficiently, whilst also minimising the associated risks, it will need to be underpinned by a long-term, cross-sectoral approach to understanding NI performance under a range of possible futures. The 'systems of systems' analysis that must form the basis for such a strategic approach does not yet exist - this inter-disciplinary research programme will provide it.The aim of the UK Infrastructure Transitions Research Consortium is to develop and demonstrate a new generation of system simulation models and tools to inform analysis, planning and design of NI. The research will deal with energy, transport, water, waste and ICT systems at a national scale, developing new methods for analysing their performance, risks and interdependencies. It will provide a virtual environment in which we will test strategies for long term investment in NI and understand how alternative strategies perform with respect to policy constraints such as reliability and security of supply, cost, carbon emissions, and adaptability to demographic and climate change.The research programme is structured around four major challenges:1. How can infrastructure capacity and demand be balanced in an uncertain future? We will develop methods for modelling capacity, demand and interdependence in NI systems in a compatible way under a wide range of technological, socio-economic and climate futures. We will thereby provide the tools needed to identify robust strategies for sustainably balancing capacity and demand.2. What are the risks of infrastructure failure and how can we adapt NI to make it more resilient?We will analyse the risks of interdependent infrastructure failure by establishing network models of NI and analysing the consequences of failure for people and the economy. Information on key vulnerabilities and risks will be used to identify ways of adapting infrastructure systems to reduce risks in future.3. How do infrastructure systems evolve and interact with society and the economy? Starting with idealised simulations and working up to the national scale, we will develop new models of how infrastructure, society and the economy evolve in the long term. We will use the simulation models to demonstrate alternative long term futures for infrastructure provision and how they might be reached.4. What should the UK's strategy be for integrated provision of NI in the long term? Working with a remarkable group of project partners in government and industry, we will use our new methods to develop and test alternative strategies for Britain's NI, building an evidence-based case for a transition to sustainability. We will analyse the governance arrangements necessary to ensure that this transition is realisable in practice.A Programme Grant provides the opportunity to work flexibly with key partners in government and industry to address research challenges of national importance in a sustained way over five years. Our ambition is that through development of a new generation of tools, in concert with our government and industry partners, we will enable a revolution in the strategic analysis of NI provision in the UK, whilst at the same time becoming an international landmark programme recognised for novelty, research excellence and impact.

Our infrastructure is central to the economic prosperity of the nation and to the flourishing of a stable, yet dynamic, civil society. Its interconnected strands - the energy, transportation, water, sanitation and communication networks that provide access to services and markets and which underpin the securities of daily life - must be not only affordable and reliable but also resilient against threats such as technological uncertainty, environmental causes, economic and political change, and demographic and societal change unfolding in an increasingly uncertain world. FIBE2 CDT will lead a paradigm shift in the approach to infrastructure resilience through the creation of an inspirational doctoral training programme for talented cohorts from diverse academic and social backgrounds to conduct world-class, cutting-edge and industry-relevant research. Our goal is to develop the infrastructure professionals of the future, equipped with a versatile and cross-disciplinary skillset to meet the most complex emerging challenges, harness the full value of existing infrastructure and contribute effectively to better infrastructure decision-making in the UK. The programme's technical focus will exploit high-level interconnected research themes in advanced infrastructure materials, rethinking design & construction, digitised civil engineering, whole-life performance, built environment and global challenges, along high-level crosscutting themes in emerging technologies, performance to data to knowledge, research across scales, and risk and uncertainty. In FIBE2 CDT we offer a radical rethink to deliver innovation for the cross-disciplinary and interconnected challenges in resilient infrastructure. Our 1+3 MRes/PhD programme proposes a new approach to infrastructure research where students from different disciplines proactively forge new training and research collaborations. FIBE2 is inspired by the paradigm of a 3D 'T' shaped engineer embodying a combination of depth and breadth of knowledge, augmented by our new thinking around cross-disciplinary training and research. High level Infrastructure Engineering concepts will be interlinked and related to the detailed technical fundamentals that underpin them in bespoke core and elective modules. Cohort-based learning will bridge across the wider environmental, societal, economic, business and policy issues within the even broader context of ethics, responsible innovation and ED&I. These depth and breadth elements are interwoven and brought together through problem-based challenges using large-scale cross-disciplinary infrastructure projects. Individual student plans will be carefully crafted to harmonise the specificity of PhD research with the need for expansive understanding of threats and opportunities. The development of Resilient FIBE2 CDT students with strong personal, technical and professional resilience attributes is integral to the FIBE2 approach to training and research. The FIBE2 PhD projects will build upon Cambridge's internationally leading research, investment and funding in the diverse areas related to infrastructure and resilience. Our major strategic initiatives include >£60M funding from EPSRC and industry. Our engagements in UKCRIC, CDBB, Alan Turing and Henry Royce Institutes and our world class graduate training programmes provide an inspirational environment for the proposed CDT. The FIBE2 vision has been co-created with our 27 strategic industry partners from across all infrastructure sectors and nine international academic centre partners across the world, who have pledged over £12M. We will work together to deliver the FIBE2 CDT objectives and add new dimensions to our students' experience. The lasting impact of FIBE2 will be embodied in our students acting as role models to inspire future generations of infrastructure engineers and rising to lead the profession through all the technological and societal challenges facing UK infrastructure.
