european perspective on absorption cooling in a combined heat and power system a case study of Energy Utility and industries in sweden
Applied Energy, 2007Co-Authors: Louise Trygg, Shahnaz AmiriAbstract:Mankind is facing an escalating threat of global warming and there is increasing evidence that this is due to human activity and increased emissions of carbon dioxide. Converting from vapour compression chillers to absorption chillers in a combined heat and power (CHP) system is a measure towards sustainability as electricity consumption is replaced with electricity generation. This electricity produced in Swedish CHP-system will substitute marginally produced electricity and as result lower global emissions of carbon dioxide. The use of absorption chillers is limited in Sweden but the conditions are in fact most favourable. Rising demand of cooling and increasing electricity prices in combination with a surplus of heat during the summer in CHP system makes heat driven cooling extremely interesting in Sweden. In this paper we analyse the most cost-effective technology for cooling by comparing vapour compression chillers with heat driven absorption cooling for a local Energy Utility with a district cooling network and for industries in a Swedish municipality with CHP. Whilst this case is necessarily local in scope, the results have global relevance showing that when considering higher European electricity prices, and when natural gas is introduced, absorption cooling is the most cost-effective solution for both industries and for the Energy supplier. This will result in a resource effective Energy system with a possibility to reduce global emissions of CO2 with 80%, a 300% lower system cost, and a 170% reduction of the cost of producing cooling due to revenues from electricity production. The results also show that, with these prerequisites, a decrease in COP of the absorption chillers will not have a negative impact on the cost-effectiveness of the system, due to increased electricity production.

the discourses of power governmental approaches to business models in the renewable Energy transition
Energy Policy, 2019Co-Authors: Scott T. Bryant, Karla Straker, Cara WrigleyAbstract:Abstract Government policies continue to grapple with the direction of the Energy industry as the uptake of variable renewable Energy (VRE) continues to impact the viability of traditional Energy Utility business models. To understand current governmental discourses and approaches to planning for a rapidly changing sector, the discourses of 63 European and Australasian Energy strategy documents were identified and analysed using content analysis. Findings identified 6 Energy strategy discourses: Energy Scout, Energy Pontificator, Energy Muddler, Political Footballer, Pure Politics, and Neoliberal Energy Economics. The research uncovered that although all discourses are focused on providing Energy-security, affordability and reliability to their citizens and industry, only some touch upon the need for new business models to deal with changing Energy market landscapes. All discourses were found to rarely consider the future impact of increasing VRE on the business models of Energy companies within the Energy sector. This paper outlines proposed actions for policymakers of each of the 6 Energy discourses to adapt their future Energy strategies to better deal with the ongoing uptake of VRE. Ultimately, without viable business models to back it, the best renewable technology and policy will fall short of the transition required to develop a sustainable Energy sector.

The typologies of power: Energy Utility business models in an increasingly renewable sector
Journal of Cleaner Production, 2018Co-Authors: Scott T. Bryant, Karla Straker, Cara WrigleyAbstract:In the last decade Energy utilities have been confronted with the challenge of maintaining business-as-usual Energy production in a world seeking to dramatically increase levels of variable renewable Energy (VRE) in the Energy sector. To understand the state of business models in this changing sector, 50 Australasian and European Energy utilities were analysed. Findings identified 4 emerging Energy Utility and Utility equivalent business model typologies, in addition to the existing Traditional Energy Utility typology: the Green Energy Utility, the Cooperative Energy Utility, the Prosumer Energy Utility, and the Prosumer Facilitator. The study revealed that whilst Energy utilities and Energy equivalent utilities are aware of the need for innovation and new value propositions to deal with the changing Energy market landscape, there is a gap regarding how they will financially adapt to the impact of increased VRE. All typologies were found to be financially vulnerable to increasing levels of VRE capacity present in the Energy sector. More specifically, the business models and support business strategies rarely considered the potential future impact that VRE would have on their viability. This paper highlights proposed future routes of business model adaptation for the five typologies, and provides insights for VRE uptake in practice and policy.

the co evolutionary relationship between Energy service companies and the uk Energy system implications for a low carbon transition
Energy Policy, 2013Co-Authors: Matthew. Hannon, Timothy J Foxon, William F GaleAbstract:The Energy Service Company (ESCo) business model is designed to reward businesses by satisfying consumers’ Energy needs at less cost and with fewer carbon emissions via Energy demand management and/or sustainable supply measures. In contrast, the revenue of the incumbent Energy Utility Company (EUCo) model is coupled with the sale of units of Energy, which are predominantly sourced from fossil fuels. The latter is currently dominant in the UK. This paper addresses two questions. First, why has the ESCo model traditionally been confined to niche applications? Second, what role is the ESCo model likely to play in the transition to a low-carbon UK Energy system? To answer these, the paper examines the core characteristics of the ESCo model, relative to the EUCo model. The paper then examines how ESCos have co-evolved with the various dimensions of the Energy system (i.e. ecosystems, institutions, user practices, technologies and business models) to provide insight into how ESCos might help to shape the future UK Energy system. We suggest that institutional and technological changes within the UK Energy system could result in a more favourable selection environment for ESCos, consequently enabling the ESCo model to proliferate at the expense of the EUCo model.

Co-evolution of innovative business models and sustainability transitions : the case of the Energy Service Company (ESCo) model and the UK Energy system
Phd thesis University Leeds, 2012Co-Authors: Matthew. HannonAbstract:There is a growing consensus that the current Energy system we rely on is fundamentally unsustainable and that it will have to be transformed if we are to continue to satisfy our Energy needs in the future. At present we have a poor understanding of the role that the development and implementation of innovative business models, designed to satisfy our Energy needs in a sustainable manner, could play in facilitating a transition to a sustainable Energy system. To improve this understanding, this thesis develops an analytical framework that integrates co-evolutionary and business model theories, and applies this framework to analyse the case of the Energy Service Company (ESCo) business model and the wider UK Energy system. The thesis begins by presenting the core characteristics of the ESCo business model and its key variants; its strengths and weaknesses; and the factors that have constrained and enabled the uptake of this sustainable business model. It then examines the coevolutionary relationship the ESCo model shares with the UK Energy system to explain not only why the model has struggled to gain traction, compared to the incumbent Energy Utility company (EUCo) model, but also the role the ESCo model could play in a transition to a sustainable UK Energy system. In light of the empirical investigation, the research finds that the development and adoption of the ESCo business model could play a valuable role in facilitating transitions to sustainable Energy systems. However, it is likely to struggle to gain traction due to ESCos’ poor fitness with the prevailing selection environment, which can in part be attributed to the causal influence of the unsustainable, incumbent EUCo model. Conversely, worsening ecosystem crises, the introduction of supportive regulation and positive feedbacks associated with the adoption of this model by new and incumbent system actors could help the ESCo model to proliferate and thus, have an important influence on the transition to a sustainable Energy system.
