This document provides a road map for Photovoltaics (PV) research in the UK. It covers PV materials, cell and module design and manufacture and applications including BOS components. It is specific to the UK and reflects the strengths and weaknesses of the research base in the UK, although it is compatible with the roadmaps of other countries, particularly the one recently developed for the European Community. Its primary aim is to identify priority areas for UK PV research and assist the research funding agencies, particularly EPSRC, DTI and the Carbon Trust, in developing their research programmes, but it also considers the need to develop UK capacity, both in terms of expertise and research facilities.

Research cannot take place in a commercial vacuum, and although not its primary function, the road map will outline the context for PV research in the UK. The potential for market growth in the UK and more widely is outlined and the need for market stimulation in the UK discussed.

The road map reflects the outcomes of a two day PV road mapping exercise, organised by the UKERC Meeting Place, that took place in Edinburgh in July 2006, together with inputs from a number of the attendees over the following weeks and subsequently contributions from the wider researcher community in response to an initial draft. The road map has also been subject to international peer review, and we indebted to these reviewers for their input.

This working paper considers the risks and opportunities posed to UK heat sector businesses by a potential transformation towards a low-carbon heat system in the UK. It is an output from the Heat, Incumbency and Transformations (HIT) project which is part of the UK Energy Research Centre programme.

The HIT project is investigating the idea of incumbency, considering what the term means, how it is present in the UKs heat sector and what the implications of incumbency are for the UKs potential transformation from a high carbon heat system to a low-carbon heat system.

The previous working paper developed a working definition of incumbency (Loweset al., 2017). This working paper forms the second phase of the project, exploring who the incumbents are in the UK heat system and the implications of the potential transformation for incumbents.

UKERC have submitted a response to the BEIS call for evidence on the future for small-scale low-carbon generation. This consultation sought to identify the role that small-scale low-carbon generation can play in the UK shift to clean growth by further understanding:

• The challenges and opportunities from small-scale low-carbon generation in contributing to government's objectives for clean, secure, affordable and flexible power; and
• The role for government and the private sector in overcoming these challenges and realising these opportunities.

In our submission we responded to the individual points raised in the call, drawing on two streams of work undertaken as part of the UKERC research programme. The first stream concerns community energy, drawing primarily on data from the UKERC Financing Community Energy project. This project has collected and analysed data from a number of sources:

• Quantitative data gathered as part of a UK-wide survey of community energy finance and business models. This dataset covers 145 community energy projects run by 48 different community energy organisations.
• Qualitative data on community energy organisations' suggestions for changes in public policy and industry practice, and their plans for the future, gathered as part of the same UK-wide survey.
• Further qualitative data on community energy organisations' views on pathways to future decentralised energy business models, gathered at workshops held as part of the Manchester Mayor's Green Summit process, and the Community Energy England annual conference 2018.
• A wide range of other data and literature, including access to the dataset collected for Community Energy England's 2017 State of the Sector Survey, covering 220 community energy organisations in England, Wales and Northern Ireland.

The second stream draws on a number of recent UKERC publications on electricity systems and networks :

• Developing low carbon networks for a low-carbon future
• Security of electricity supply in a low-carbon Britain
• The Costs and Impacts of Intermittency
• Delivering a highly distributed electricity system: Technical, regulatory and policy challenges.

The Code for Sustainable Homes has been developed to enable a step change in sustainable building practice for new homes. It has been prepared by the Government in close working consultation with the Building Research Establishment (BRE) and Construction Industry Research and Information Association (CIRIA), and through consultation with a Senior Steering Group consisting of Government, industry and NGO representatives.

The Code is intended as a single national standard to guide industry in the design and construction of sustainable homes. It is a means of driving continuous improvement, greater innovation and exemplary achievement in sustainable home building.

The Code will complement the system of Energy Performance Certificates which is being introduced in June 2007 under the Energy Performance of Buildings Directive (EPBD). The EPBD will require that all new homes (and in due course other homes, when they are sold or leased) have an Energy Performance Certificate providing key information about the energy efficiency/carbon performance of the home. Energy assessment under the Code will use the same calculation methodology therefore avoiding the need for duplication.

This document is divided into the following sections:

1. What is the code for sustainable homes?
2. How does the code work?
3. Summary of code benefits
4. Code standards
5. Practical Examples

This report presents a case study of Edinburgh Community Solar Cooperative, exploring how it financed the project against a backdrop of diminishing government support for grassroots sustainable development.

This report presents the first of four case studies of UK community energy organisations, exploring how these organisations have sought to finance their projects against a backdrop of diminishing government support for grassroots sustainable development.

Edinburgh Community Solar Cooperative (ECSC) is a Community Benefit Society (BenCom). Its objectives are a combination of environmental and social, with an explicit focus on reducing emissions, alleviating fuel poverty, improving energy security and promoting sustainable development education.

ECSC quickly settled on renewable power generation as a means of delivering this combination of environmental andsocial value. Today it operates 1.4 MW of solar PV panels on the roofs of 24 council-owned properties in Edinburgh, including schools, leisure centres and community halls.

Commencing in 2016, the Financing Community Energy project provides a comprehensive quantitative and qualitative analysis of the role of finance in the evolution of the UK community energy sector. This report presents the third of four case studies of UK community energy organisations, exploring how these organisations have sought to finance their projects against a backdrop of diminishing government support for grassroots sustainable development.

Gwent Energy (Wales) was formed in 2009 to deliver environmental benefit and cost savings to its local community. It aims to help local consumers save money on their energy bills through a combination of renewable energy, efficiency, storage and electric vehicle charging interventions, whilst simultaneously generating a surplus to fund local community initiatives.

The Paper considers first demand for indium and tellurium from the PV industry, now and in future. Whilst a range of scenarios exist for the role of PV in the global energy mix there is considerable agreement that the share of PV per se and thin film devices in particular is expected to expand considerably in the light of carbon abatement goals.

The paper then considers the supply of indium and tellurium. It provides a detailed review of the processes used to extract and refine them, and discusses the issues associated with producing these secondary metals which are extracted as trace elements during the production of primary metals such as zinc and copper. The Paper finds that there are considerable complexities associated with reported reserves and an absence of meaningful data on resources. Again, existing estimates of availability for the PV market are reviewed. This alsoreveals considerable variation within the literature and the use of a wide a range of assumptions upon which to base resource availability.

The paper concludes that there is no immediate cause for concern about availability of either indium or tellurium. PV occupies a small fraction of current markets and there is evidence of considerable potential to increase the extraction of both metals because a sizeable proportion of the material potentially available from primary metal extraction is not currently utilised. Moreover, there is potential to increase recycling of products containing indium or tellurium, for example from flat screens. However, the scale of the roll out of PV ~ vi ~ envisaged in some scenarios could imply a large expansion in the demand for indium and tellurium. There is no reason to believe that this is not feasible, however adequate data on reserves and resources do not exist. Resource estimates are not available and simplistic assumptions such as using current production or crustal abundance to estimate potential supply cannot provide any meaningful insight into future production. A scenario approach that links production to primary metals is appropriate. We conclude that considerable further research is needed to characterise indium and tellurium resources and the economic feasibility of expanding production.

There is increasing concern that future supply of some lesser known critical metals will not be sufficient to meet rising demand in the low-carbon technology sector. A rising global population, significant economic growth in the developing world, and increasing technological sophistication have all contributed to a surge in demand for a broad range of metal resources. In the future, this trend is expected to continue as the growth in low-carbon technologies compounds these other drivers of demand. This report examines the issues surrounding future supply and demand for critical metals - including Cobalt, Gallium, Germanium, Indium, Lithium, Platinum, Selenium, Silver, Tellurium, and Rare earth Metals.

The Office of the Deputy Prime Minister ('the ODPM') has commissioned this research into Planning for Renewable Energy as part of its New Horizons research programme. The New Horizons programme aims to introduce new research ideas, develop innovative, cross-cutting approaches to research and offer a forward-thinking perspective on medium- to long-term policy issues pertaining to the ODPM.

The specific objectives of the Planning for Renewable Energy research have been:

The research programme was devised in May 2002 and the research was conducted over the course of eleven months, commencing in October 2002.

The research is especially timely because the results are able to inform the revision of Planning Policy Guidance 22 (renewable energy) and the accompanying documentation for the new Planning Policy Statement 22 (renewable energy). The research has also been able to take account of the Energy White Paper, Our Energy Future, Creating a Low Carbon Economy (2003) and The Sustainable communities Plan (2003), both of which were published during the course of the project.

Perhaps the single most important concluding remark for ODPM is to point out that its extensive responsibilities for the built environment mean that it cannot avoid a significant role in the development of policies on renewables over the course of the next five to ten years. Indeed, given the potentially vital role of the linkages between planning, regeneration and governance, and the ODPM's responsibilities across these areas, the Department could reasonably be considered to be the most important in helping the country to become a low carbon economy

Against a policy background set principally by the Energy White Paper 2003 and the Sustainable Communities Plan 2003, Brook Lyndhurst's research work on "Planning for Renewable Energy" approached the issue of renewable energy from three perspectives:

The particular objectives of the research were:

Our research suggests that the issue(s) of renewable energy is, in general, restricted to a small but enthusiastic minority of players in regional and local government. For the mainstream practitioner in land-use planning and urban regeneration, energy issues generally, and renewable energy issues in particular, have a low priority.

Those practitioners with responsibility for renewables, while making some headway in forging links with regional planners, appear to operate discretely from regeneration practitioners at all levels and planners at the local level. As a result, no "critical mass" of concern has come about, so there has been no significant impetus for the development of a "community of interest" encompassing planning, regeneration and renewable energy personnel, at both regional and local levels.

In the longer term, however, it would seem that if the UK is to achieve truly dramatic reductions in its emissions of carbon dioxide (as envisaged, most obviously, by the Royal Commission on Environmental Pollution), then a more radical and far-reaching programme of change will be required.

UKERC offers its views on the research funding landscape. Recommendations are highlighted in bold.

Energy System Demonstrators are physical demonstrations testing new technologies for low-carbon energy infrastructure.

A review of energy systems demonstrator projects in the UK was undertaken for UKERC by the Energy Systems Research Unit (ESRU) at the University of Strathclyde. The review encompassed 119 demonstrators and consisted of two phases: 1) the identification of demonstrator projects and 2) an analysis of projects and their outcomes.

Energy demonstrators

The review defined an energy system demonstrator as "the deployment and testing of more than one technology type that could underpin the operation of a low-carbon energy infrastructure in the future". Only demonstrators that post-date the 2008 Climate Change Act were included and that included a physical demonstration at one or more UK sites. 119 projects were identified that met the search criteria.

There were two phases of review activity. Phase 1 involved identification and documentation of demonstration projects, involving a systematic search to identify and record the details of projects. Phase 2 was a review of project outcomes and outputs, particularly end-of-project evaluations, covering technical, economic and social outcomes where available.

The review outputs (available here) are a final report summarising the findings, 119 demonstrator project summaries (the Phase 1 reports), 119 demonstrator output analyses (the Phase 2 reports) and a GIS (Geographic Information System) map and database showing the locations and project details of the demonstrators.

The final report, attendant project summaries and GIS data are intended to provide policy makers and funding bodies with an overview of the existing demonstrator "landscape", enabling decisions on future demonstrator calls and the focus of those calls to be made with a clearer knowledge of what has already been done.

It argues that, since its emergence in the UK in the late 1990s, community energy has grown through finding opportunities for smaller scale, decentralised energy activities in the UKs highly centralised energy system. The combination of development of renewable energy technologies, and the launch of the governments Feed-In Tariff Scheme (FITS) in 2010, produced a boom in the sector, especially around solar electricity generation.

Recent cuts to FITS rates and other policy changes place community energy at a crossroads. Some renewables activity will continue, but groups are exploring a wide range of activities, partnerships, and business models. We are engaging with the sector around outputs from our research, which include a survey and case studies, to co-develop recommendations and pathways for the future.

Regen has run the Solar Commission, a project that has been set up as part of the UKERC Whole Systems Network Fund.

Innovation and falling costs are leading to solar power playing an increasing role in the energy system. The UK has considerable scientific, technical and business experience in solar power and including technology, power storage, control systems, financing, and power purchase arrangements.

The role of the Commission has been to stimulate new thinking and encourage collaboration between academics, industry and system operators on the role of solar power in the energy system. The Commission examined areas where the UK could use its scientific and technical capabilities to play a leading role in innovation and industrial strategy opportunities in solar power.

The Commission was formed of industry leaders, academics and others and the Commissioners were responsible for investigating the future role of solar power in the energy system, considering the UK’s areas of strength in research and innovation in solar.

The findings will be used to inform and influence decision makers and leading players in the UK energy system and have been published in a non technical briefing at the House of Lords on 9 July 2019. The project engaged new voices and maximise female representation through collaboration with Regen’s Entrepreneurial Women in Renewables initiative.

This report presents the conclusions of the Commission, setting out:

• key areas of innovation in the solar PV value chain where the UK has competitive advantage.
• the UK’s capabilities in these innovation areas.
• recommendations for UK to capitalise on the global growth opportunity.

A key finding of the Commission is that the UK has strong capabilities in many of the disruptiveinnovations transforming the solar PV market. The UK’s strengths in areas like innovative solar celltechnologies, storage, information and communication technologies and finance have sometimesbeen obscured by a focus on China’s domination of the manufacture of current generation crystallinesolar PV panels.

This UKERC Research Landscape provides an overview of the competencies and publicly funded activities in solar energy research, development and demonstration (RD&D) in the UK.

This working paper examines global and UK trends in cost trajectories of PV technologies, at module and system level, with the aim of:

• 1. Examining key trends in contemporary costs and forecasted cost projections;
• 2. Discussing major drivers for cost reductions;
• 3. Identifying implications for the use of available cost estimation methodologies in forecasting PV technology costs.

The UK Energy Research Centre welcomes this opportunity to provide input to the BERR Consultation on the UK Renewable Energy Strategy. We have addressed a number of the questions posed in the consultation document calling on all UKERC members for input.

To meet the EU 15% renewable energy target will be a significant challenge for the UK. It is important to understand that reductions in the UKs total energy demand will produce proportional reductions in the renewable contribution required. Although self-evident, this simple fact is often overlooked. Indeed the UK has to date failed to achieve any reductions in energy use, in fact the reverse is true: energy consumption in the key sectors of electricity and energy for transport continues to rise steadily.

In addition to reducing the demand for energy, there will need to be a massive increase in the contribution of renewables to transport fuel (predominately biofuels), heat and electricity. This submission concentrates on renewable electricity because UKERC has core competency this area. In Table 1, below, UKERC presents an illustrative scenario for the contribution of renew

• Without the adoption of a more holistic approach that addresses BETTA structural reform and network regulation, it is difficult to see how a satisfactory resolution of the transmission access issue can be achieved.
• It is proposed that more strategic and unified development of the onshore and offshore network together with the provision of interconnection would be encouraged through common or at least zonal ownership of offshore transmission assets, while cost-effectiveness and the efficient delivery of assets could be achieved through tendering and outsourcing construction.
• Modern distribution networks are not typically designed to accommodate generation; a number of technical and operational challenges will need to be addressed in order for the connection of significant amounts of distributed generation on these networks.
• The consequences of intermittency or variability of input will need to be managed by a combination of retaining conventional plant and developing demand response. Additionally, interconnection with adjacent transmission systems and improved forecasting of wind resource and maintaining geographic diversity of wind generation could also reduce the impacts of intermittency.
• The role of smart grids will be to enhance the capacity and utilisation of the electricity grid (both transmission and distribution) by means other than investing in traditional transmission assets and, via the deployment of smart metering, massively increase the contribution of the demand side to system security and the decarbonisation of the heat and transport sectors.
• UKERC is concerned that a major opportunity will be missed unless there is a timely change to a regulatory regime that encourages objective and costefficient choices between investment and smart grid solutions.

We welcome the Welsh Government's interest in locally owned renewable energy. Our response draws on a range of research undertaken by the Heat and the City research group at the University of Edinburgh, including a UK-wide study of local authorities and energy; and on the Financing Community Energy research project being led by Tyndall Manchester.

In our response we made the following general comments, before responding to individual points raised in the call:

• We suggest that greater attention should be paid to city/town/settlement scale infrastructure for a low carbon energy system, including area based upgrading of the built environment and low carbon heating infrastructure. Heat and energy efficiency for a low energy building stock are crucial to meeting Welsh and UK Government legally binding targets for carbon abatement.
• At national scale, Wales has opportunities for sharing risk, costs and benefits of energy developments - i.e. the direct benefit to the citizens of Wales through public ownership and the aggregate costs across society of decarbonisation.
• Local Authority planning and ownership could be considered further as key components to securing greater local control and accountability, and achieving Welsh Government objectives. Our research indicates that further developing specific roles, powers, resources and responsibilities of local institutional actors in energy planning and ownership, especially Local Authorities would also add value to Welsh society and economy.
