Tackling climate change, providing energy security and delivering sustainable energy solutions are major challenges faced by civil society. The social, environmental and economic cost of these challenges means that it is vital that there is a research focus on improving the conversion and use of thermal energy. A great deal of research and development is continuing to take place to reduce energy consumption and deliver cost-effective solutions aimed at helping the UK achieve its target of reducing greenhouse gas emissions by 80 per cent by 2050. Improved thermal energy performance impacts on industry through reduced energy costs, reduced emissions, and enhanced energy security. Improving efficiency and reducing emissions is necessary to increase productivity, support growth in the economy and maintain a globally competitive manufacturing sector. In the UK, residential and commercial buildings are responsible for approximately 40% of the UK's total non-transport energy use, with space heating and hot water accounting for almost 80% of residential and 60% of commercial energy use. Thermal energy demand has continued to increase over the past 40 years, even though home thermal energy efficiency has been improving. Improved thermal energy conversion and utilisation results in reduced emissions, reduced costs for industrial and domestic consumers and supports a more stable energy security position. In the UK, thermal energy (heating and cooling) is the largest use of energy in our society and cooling demand set to increase as a result of climate change. The need to address the thermal energy challenge at a multi-disciplinary level is essential and consequently this newly established network will support the technical, social, economic and environmental challenges, and the potential solutions. It is crucial to take account of the current and future economic, social, environmental and legislative barriers and incentives associated with thermal energy. The Thermal Energy Challenge Network will support synergistic approaches which offer opportunities for improved sustainable use of thermal energy which has previously been largely neglected. This approach can result in substantial energy demand reductions but collaboration and networking is essential if this is to be achieved. A combination of technological solutions working in a multi-disciplinary manner with engineers, physical scientists, and social scientists is essential and this will be encouraged and supported by the Thermal Energy Challenge Network.

The UK is committed to a target of reducing greenhouse gas emissions by 80% before 2050. With over 40% of fossil fuels used for low temperature heating and 16% of electricity used for cooling these are key areas that must be addressed. The vision of our interdisciplinary centre is to develop a portfolio of technologies that will deliver heat and cold cost-effectively and with such high efficiency as to enable the target to be met, and to create well planned and robust Business, Infrastructure and Technology Roadmaps to implementation. Features of our approach to meeting the challenge are: a) Integration of economic, behavioural, policy and capability/skills factors together with the science/technology research to produce solutions that are technically excellent, compatible with and appealing to business, end-users, manufacturers and installers. b) Managing our research efforts in Delivery Temperature Work Packages (DTWPs) (freezing/cooling, space heating, process heat) so that exemplar study solutions will be applicable in more than one sector (e.g. Commercial/Residential, Commercial/Industrial). c) The sub-tasks (projects) of the DTWPs will be assigned to distinct phases: 1st Wave technologies or products will become operational in a 5-10 year timescale, 2nd Wave ideas and concepts for application in the longer term and an important part of the 2050 energy landscape. 1st Wave projects will lead to a demonstration or field trial with an end user and 2nd Wave projects will lead to a proof-of-concept (PoC) assessment. d) Being market and emission-target driven, research will focus on needs and high volume markets that offer large emission reduction potential to maximise impact. Phase 1 (near term) activities must promise high impact in terms of CO2 emissions reduction and technologies that have short turnaround times/high rates of churn will be prioritised. e) A major dissemination network that engages with core industry stakeholders, end users, contractors and SMEs in regular workshops and also works towards a Skills Capability Development Programme to identify the new skills needed by the installers and operators of the future. The SIRACH (Sustainable Innovation in Refrigeration Air Conditioning and Heating) Network will operate at national and international levels to maximise impact and findings will be included in teaching material aimed at the development of tomorrow's engineering professionals. f) To allow the balance and timing of projects to evolve as results are delivered/analysed and to maximise overall value for money and impact of the centre only 50% of requested resources are earmarked in advance. g) Each DTWP will generally involve the complete multidisciplinary team in screening different solutions, then pursuing one or two chosen options to realisation and test. Our consortium brings together four partners: Warwick, Loughborough, Ulster and London South Bank Universities with proven track records in electric and gas heat pumps, refrigeration technology, heat storage as well as policy / regulation, end-user behaviour and business modelling. Industrial, commercial, NGO and regulatory resources and advice will come from major stakeholders such as DECC, Energy Technologies Institute, National Grid, British Gas, Asda, Co-operative Group, Hewlett Packard, Institute of Refrigeration, Northern Ireland Housing Executive. An Advisory Board with representatives from Industry, Government, Commerce, and Energy Providers as well as international representation from centres of excellence in Germany, Italy and Australia will provide guidance. Collaboration (staff/student exchange, sharing of results etc.) with government-funded thermal energy centres in Germany (at Fraunhofer ISE), Italy (PoliMi, Milan) and Australia (CSIRO) clearly demonstrate the international relevance and importance of the topic and will enhance the effectiveness of the international effort to combat climate change.

The UK food chain, comprising agricultural production, manufacturing, distribution, retail and consumption, involves more than 300,000 enterprises and employs 3.6 million people. The food and drink industry is the largest manufacturing sector, employing 500,000 people and contributing £80 billion to the economy. It is also estimated that the food chain is responsible for 160 MtCO2e emissions and 15 Mt of food waste, causing significant environmental impacts. Energy is an important input in all stages of the food chain and is responsible for 18% of the UK's final energy demand. In recent years, progress has been made in the reduction of energy consumption and emissions from the food chain primarily through the application of well proven technologies that could lead to quick return on investment. To make further progress, however, significant innovations will have to be made in approaches and technologies at all stages of the food chain, taking a holistic view of the chain and the interactions both within the chain and the external environment. The EPSRC Centre for Sustainable Energy Use in Food Chains will make significant contributions in this field. It will bring together multidisciplinary research groups of substantial complementary experience and internationally leading research track record from the Universities of Brunel, Manchester and Birmingham and a large number of key stakeholders to investigate and develop innovative approaches and technologies to effect substantial end use energy demand reductions. The Centre will engage both in cutting edge research into approaches and technologies that will have significant impacts in the future, leading towards the target of 80% reduction in CO2 emissions by 2050, but also into research that will have demonstrable impacts within the initial five year lifetime of the Centre. Taking a whole systems approach, the research themes will involve: i) Simulation of energy and resource flows in the food chain, from farm-gate to plate to enable investigations of energy and resource flows between the stages of the chain and the external environment, and facilitate overall energy and resource use optimisation taking into consideration the impact of policy decisions, future food and energy prices and food consumption trends. ii) Investigation of approaches and technologies for the reduction of energy use at all stages of the chain through reduction of the energy intensity of individual processes and optimisation of resource use. It is expected that a number of new innovative and more efficient technologies and approaches for energy reduction will be developed in the lifetime of the Centre to address processing, distribution, retail and final consumption in the home and the service sector. iii) Identification of optimal ways of interaction between the food chain and the UK energy supply system to help manage varying demand and supply through distributed power generation and demand-response services to the grid. iv) Study of consumer behaviour and the impact of key influencing factors such as changing demographics, increased awareness of the needs and requirements of sustainable living, economic factors and consumption trends on the nature and structure of the food chain and energy use. Even though the focus will be on the food chain, many of the approaches and technologies developed will also be applicable to other sectors of the economy such as industry, commercial and industrial buildings and transportation of goods. The Centre will involve extensive collaboration with the user community, manufacturers of technology, Government Departments, Food Associations and other relevant research groups and networks. A key vehicle for dissemination and impact will be a Food Energy and Resource Network which will organise regular meetings and annual international conferences to disseminate the scientific outputs and engage the national and international research and user communities

Decarbonising both heating and cooling across residential, business and industry sectors is fundamental to delivering the recently announced net-zero greenhouse gas emissions targets. Such a monumental change to this sector can only be delivered through the collective advancement of science, engineering and technology combined with prudent planning, demand management and effective policy. The aim of the proposed H+C Zero Network will be to facilitate this through funded workshops, conferences and secondments which in combination will enable researchers, technology developers, managers, policymakers and funders to come together to share their progress, new knowledge and experiences. It will also directly impact on this through a series of research funding calls which will offer seed funding to address key technical, economic, social, environmental and policy challenges. The proposed Network will focus on the following five themes which are essential for decarbonising heating and cooling effectively: Theme 1 Primary engineering technologies and systems for decarbonisation Theme 2 Underpinning technologies, materials, control, retrofit and infrastructure Theme 3 Future energy systems and economics Theme 4 Social impact and end users' perspectives Theme 5 Policy Support and leadership for the transition to net-zero
