Emergence of District-Heating Networks; Barriers and Enablers in the Development Process

Infrastructure provision business models that promise resource efficiencies and additional benefits, such as job creation, community cohesion and crime reduction exist at sub-national scales. These local business models, however, exist only as isolated cases of good practice and their expansion and wider adoption has been limited in the context of many centralised systems that are currently the norm. In this contribution, we present a conceptual agent based model for analysing the potential for different actors to implement local infrastructure provision business models. The model is based on agents’ ability to overcome barriers that occur throughout the development (i.e. feasibility, business case, procurement, and construction), and operation and maintenance of alternative business models. This presents a novel approach insofar as previous models have concentrated on the acceptance of alternative value provision models rather than the emergence of underlying business models. We implement the model for the case study of district heating networks in the UK, which have the potential to significantly contribute to carbon emission reductions, but remain under-developed compared with other European countries

Business model innovation in electricity supply markets: The role of complex value in the United Kingdom

This research investigates the new opportunities that business model innovations are creating in electricity supply markets at the sub-national scale. These local supply business models can offer significant benefits to the electricity system, but also generate economic, social, and environmental values that are not well accounted for in current policy or regulation. This paper uses the UK electricity supply market to investigate new business models which rely on more complex value propositions than the incumbent utility model. Nine archetypal local supply business models are identified and their value propositions, value capture methods, and barriers to market entry are analysed. This analysis defines 'complex value' as a key concept in understanding business model innovation in the energy sector. The process of complex value identification poses a challenge to energy researchers, commercial firms and policymakers in liberalised markets; to investigate the opportunities for system efficiency and diverse outcomes that new supplier business models can offer to the electricity system

Assessing the critical material constraints on low carbon infrastructure transitions

We present an assessment method to analyze whether the disruption in supply of a group of materials endangers the transition to low-carbon infrastructure. We define criticality as the combination of the potential for supply disruption and the exposure of the system of interest to that disruption. Low-carbon energy depends on multiple technologies comprised of a multitude of materials of varying criticality. Our methodology allows us to assess the simultaneous potential for supply disruption of a range of materials. Generating a specific target level of low-carbon energy implies a dynamic roll-out of technology at a specific scale. Our approach is correspondingly dynamic, and monitors the change in criticality during the transition towards a low-carbon energy goal. It is thus not limited to the quantification of criticality of a particular material at a particular point in time. We apply our method to criticality in the proposed UK energy transition as a demonstration, with a focus on neodymium use in electric vehicles. Although we anticipate that the supply disruption of neodymium will decrease, our results show the criticality of low carbon energy generation increases, as a result of increasing exposure to neodymium-reliant technologies. We present a number of potential responses to reduce the criticality through a reduction in supply disruption potential of the exposure of the UK to that disruption

Local Electricity Supply: Opportunities, archetypes and outcomes

This report investigates how new, system-wide value opportunities have arisen in the energy system and how local electricity1 business models can capture them. The research team was composed of Dr Stephen Hall and Dr Katy Roelich of the Schools of Environment and Civil Engineering at the University of Leeds. This report develops a detailed evidence base to explore the business models and value opportunities offered by the emerging field of local electricity supply. The purpose of this report is to offer evidence-based options for enabling the local electricity supply sector in the UK

Substantiating Energy Justice: Creating a Space to Understand Energy Dilemmas

This paper explores the relationships between the moral philosophical foundations and strategic goals of two conceptions of energy justice: the “triumvirate conception” and the “principled approach”. We explore the extent to which the goals of these approaches align with their core aims and strategies. Having initially been developed to capture and reflect the values of activist-led environmental justice movements, we find that the triumvirate approach’s adoption of a trivalent conception of justice currently lies in tension with its overarching top-down approach. We note that the principled approach does not face the same tensions as the triumvirate conception of energy justice, but would benefit from illustrating the consequences of framing the same energy dilemma with conflicting moral theories. Aiming to ameliorate these limitations and further develop conceptions of energy justice, we outline a case study of hydro power in Hirakud, India and propose a framework which illustrates how using differing theories of justice to conceptualise the same energy dilemmas can result in substantially different normative framings and guidance. We illustrate how this framework, combined with a pluralistic appeal to moral theory, can enable both approaches to draw on a wider range of moral theory to assess energy dilemmas. This in turn provides a broader socio-political backdrop in which to view energy dilemmas. We outline how this backdrop contributes to the creation of a space in which the grievances of those who suffer in relation to energy systems can be heard and better understood

Closing the low-carbon material loop using a dynamic whole system approach

The transition to low carbon energy and transport systems requires an unprecedented roll-out of new infrastructure technologies, containing significant quantities of critical raw materials. Many of these technologies are based on general purpose technologies, such as permanent magnets and electric motors, that are common across different infrastructure systems. Circular economy initiatives that aim to institute better resource management practices could exploit these technological commonalities through the reuse and remanufacturing of technology components across infrastructure systems. In this paper, we analyze the implementation of such processes in the transition to low carbon electricity generation and transport on the Isle of Wight, UK. We model two scenarios relying on different renewable energy technologies, with the reuse of Lithium-ion batteries from electric vehicles for grid-attached storage. A whole-system analysis that considers both electricity and transport infrastructure demonstrates that the optimal choice of renewable technology can be dependent on opportunities for component reuse and material recycling between the different infrastructure systems. Hydrogen fuel cell based transport makes use of platinum from obsolete catalytic converters whereas lithium-ion batteries can be reused for grid-attached storage when they are no longer useful in vehicles. Trade-offs exist between the efficiency of technology reuse, which eliminates the need for new technologies for grid attached storage completely by 2033, and the higher flexibility afforded by recycling at the material level; reducing primary material demand for Lithium by 51% in 2033 compared to 30% achieved by battery reuse. This analysis demonstrates the value of a methodology that combines detailed representations of technologies and components with a systemic approach that includes multiple, interconnected infrastructure systems

Physical and institutional challenges of low-carbon infrastructure transitions: constraints and potential solutions

There is growing recognition that the United Kingdom’s ageing infrastructure systems are unable to deliver the radical reductions in greenhouse gas emissions necessary to avoid dangerous climate change. As such, there is an imperative to transform our infrastructure systems towards alternatives that deliver services reliably but within environmental limits. There are significant challenges to achieving this transformation but most current analysis focusses on the technical and economic challenges of infrastructure transition. This thesis examines two under-studied challenges to low-carbon infrastructure transition: one principally physical; the constraints posed by the disruption in supply of critical materials embedded in low-carbon energy technologies; and one institutional; the constraints to alternative modes of infrastructure operation from current policy and regulation in water and energy infrastructure. It aims to not only characterise these constraints but also to identify policy responses to alleviate constraints. The two constraints differ greatly in character and contrasting methods were used to analyse the nature and scale of each constraint. Material criticality constraints were examined using a quantitative, indicator-based method developed in this thesis to dynamically assess the risk of critical material disruption to low-carbon electricity generation. Policy and regulatory constraints were analysed using theory building from case study analysis to identify the mechanisms by which development of alternative modes of operation were constrained by policy and regulation. Despite the differing scale and nature of the constraints, there are some striking similarities in the potential policy responses to constraints. The results of both analyses emphasize the importance of diversity in the future infrastructure system, the need for a more targeted approach to policy and stress the need for integrated action across policy areas. The dual focus on understanding and responding to constraints forced a balance between dealing with complexity and enabling action. This highlighted the importance of adaptive policy, which takes action in the face of uncertainty but is able to modify its course as system understanding develops

Supporting decision making for resilient net-zero infrastructure

In this policy brief, we introduce a suite of technologies which use underground assets to store heat and energy, or provide a low carbon means of energy generation. These present regional authorities with an opportunity for low carbon economic regeneration which is sympathetic to local industrial heritage
