[en] Under the current macro-economic trends, the so far abundant support system for renewables (mainly in the form of feed-in-tariffs and quota systems) has been drastically modified. In many EU countries, companies are trying to find alternative ways to secure financing for their renewable energy projects. Therefore, new ways of attracting private capital for the realisation of green energy goals have to replace the old schemes. Some new forms of financing are coming together with the EU Cohesion Policy 2014-2020 (project guarantees, packaging of small project for micro-financing schemes at the regional level, preferential loan instead of subsidies etc.). Advanced financial structures are likely to play an increasingly important role in the allocation of risk and reward among different investor classes. The finance and investment gap needs to be filled by the private sector. The challenge is to identify the appropriate policy options and financial tools to attract and scale-up private investments. There are, however, already innovative and promising business and financial models to promote the deployment of RES in the EU. The aim of the EurObserv'ER case studies is to find such examples and describe them so as to put forward the best practices and the replicability of the future promising financing mechanisms. EurObserv'ER will aim at choosing only the most promising ones and try to describe them in order to promote replicability in other geographical areas. The selection criteria for the choice of case studies should ensure (i) diversity across regions and RES, (ii) diversity across finance instruments/mechanisms, (iii) success of approach and its potential to be replicated, (iv) and a wide range of the 'size' of actors/ investors and the resulting RES investments (capacity). The current selection also takes into account the fact that there were already some case studies published in 2014, 2015, 2018 and 2019. These are also available for download on the project web site: www.eurobserv-er.org
[en] After some brief recalls of definitions (surface and deep geothermal energy), indications of some operational characteristics (high and low energy geothermal, heat pumps), indications of the various fields of application of these different approaches and techniques, indications of some key data (turnover, production, potential), this publication proposes an overview of the various assets of this sector: a local, available, performing, and clean energy, a structured sector. It outlines the essential role of geothermal energy in reaching the objectives of the law on energy transition, but also that the development rate is still insufficient to reach the objectives defined for 2023. Then, measures and actions are proposed to free the whole potential of the geothermal energy sectors.
[en] Full text: Australia's electricity generation system needs to change to meet the challenge of reducing carbon emissions. To meet this challenge, various policies such as carbon pricing or renewable energy targets have focused upon the generation component with little attention being given to the network costs. Generation costs in 2016 in New South Wales represented 24 percent of our power bills while network costs were more than double that proportion at 55 percent (Figure 1) Generating costs (Figure 2) are going from circa $55/MWh in 2016 to around $105/MWh next year (see figure next page). Its hoped that transmission and distribution costs for the poles and wires may be stabilising. If we start introducing non-generating devices such as battery storage, pumped hydro storage, longer transmission lines to transmit wind and solar and frequency stabilising devices then significant increases in network costs will follow. We have been ill served by the consideration of nuclear energy in both the Power Generation Technology Report in 2015 and more recently by the Finkel Report In this presentation Rob Parker will look at the spectrum of reactor prices and vendors. If correctly selected nuclear energy could stabilise current generating prices and also reduce further network cost increases. These two factors now make nuclear energy competitive in Australia. With a national nuclear plan, business can have greater confidence in long term power prices and Australia can create a century long power generating asset to underpin our wealth and future competitiveness.

[en] Whereas data centres are an important issue in terms of energy consumption and water consumption for their cooling, this study first outlines that their energy efficiency is therefore a huge stake from and economic and energy point of view, that their development has however a brilliant future, and that their cooling is a crucial issue. Then, five fields of innovation are considered to properly address the issue of cooling and valorisation of the dissipated heat: the electric power network and its associated equipment, computing components of data centres and supported components, urbanisation and exploitation of the computer room, and technologies of valorisation of the dissipated heat. The report proposes an overview of leaders of the sector and notices the impossibility to choose a technological way to the detriment of an other. Some examples of R and D works and actors in the field of liquid cooling are evoked. A two-level R and D road-map is proposed to address the issue of data centre cooling. A Power point version of the study is proposed which highlights results.
[en] In a study on vigilance in the supply chains of minerals used in the energy transition, Sherpa highlights the shortcomings of the measures presented in the vigilance plans of nine French companies, more than three years after the adoption of the Duty of Vigilance Law. Fighting global warming requires a reduction in greenhouse gas emissions to reach the climate targets set out in the Paris agreement. However, the current implementation of the energy transition, through the development of electric mobility or the deployment of renewable energies, requires increasing supplies of certain minerals used to produce batteries or solar panels. The World Bank has identified at least 17 minerals essential for these technologies, such as lithium, cobalt, and neodymium. Yet the extraction and supply of these minerals can lead to environmental and human rights adverse impacts. The Business and Human Rights Resource Centre has documented more than 160 cases of human rights and environmental allegations for the 37 largest companies involved in the extraction and use of minerals crucial in the transition to low-carbon technologies. Sherpa sought to verify whether the vigilance plans published by nine French companies subject to the Duty of Vigilance Law contain reasonable and adequate vigilance measures to identify such risks and prevent such impacts. In particular, our research shows that the content of the vigilance plans analyzed is insufficient, as the risks associated with these minerals rarely appear in these plans, and the listed measures are often imprecise and detached from the companies' activities. Companies often limit themselves to presenting tools that they were already using before the law existed, such as audits or certifications, but which in practice do not make it possible to avoid damage linked to the use of these minerals.
[en] The present dissertation aimed at estimating the photovoltaic (PV) generation potential at the Pici Campus of the Federal University of Ceara (UFC). Data collected during the period of one year - September 2016 to August 2017 - were evaluated on a photovoltaic (PV) distributed generation (DG) connected to the distribution network of the Pici Campus/UFC and the irradiation in the vicinity of the PV DG. Representative day charts were plotted for each month in the sample period. The annual average irradiance (Igmês m), average electricity generation (Gmês m), average PV capacity factor (FCmed) and PV efficiency (eFV) for the study region were of 5.21 kWh/m²/day, 7.55 kWh/day (0.7754kWh/m²/day), 20.98% and 14.94%, respectively. The equivalence in the reduction of CO2 provided by the PV DG (ECO2) in the LEA in the period studied was 255.64 kgCO2/year. The analysis of the PV potential of the Pici Campus was done with a focus on the ceilings of the buildings of the Technology Center (CT-UFC), Science Center (CC-UFC), Agricultural Science Center (CCA-UFC), Institute of Culture and Art/University Restaurant (ICA-UFC/RU-UFC) and University Library (BU-UFC), which are separated into five sets of areas that have a PV generation potential of 2.67 GWh/year, 4.80 GWh/year, 1.97 GWh/year, 2.25 GWh/year and 0.55 GWh/year respectively, totaling a PV potential of 12.25 GWh/year, with a total installed capacity of 6.67 MWp. For case 1, cost of PV DG in the Pici Campus based on the Investment of the Federal Institute of Ceara (IFCE), the investment for the implementation of the PV DG system (CFV) is R $ 29,262,587.57. For Case 2, cost of PV DG in the Pici Campus based on the Investment in the solar park of Nova Olinda, Piaui the required investment is R $ 20,400,732.78. The amount of the invoice for the Campus do Pici in this period was R $ 8,330,313.61. The consumption of electric energy was 14.33 GWh, with 1.19 GWh consumed in peak time (HP) and 13.14 GWh consumed in the off-peak time HFP. The average Gmês m of the Pici Campus is able to offset R $ 5,047,425.79 (93.29%) of the value of energy consumption in the HFP. The return period of the PV DG PRIFV) investment installed in the Pici Campus is from four to six years. (author)
[en] As the global electricity systems are shaped by decentralisation, digitalisation and decarbonization, the World Energy Council's Innovation Insights Briefs explore the new frontiers in energy transitions and the challenges of keeping pace with fast moving developments. We use leadership interviews to map the state of play and case studies across the whole energy landscape and build a broader and deeper picture of new developments within and beyond the new energy technology value chain and business ecosystem. The topic of this briefing is energy storage. We interviewed energy leaders from 17 countries, exploring recent progress in terms of technology, business models and enabling policies. We showcase these in 10 case studies. While the brief addresses energy storage as a whole, most insights are focused on electrical storage. Our research highlighted that today's mainstream storage technologies are unlikely to be sufficient to meet future flexibility requirements resulting from further decentralisation and decarbonization efforts. Furthermore, a restricted focus on lithium-ion batteries is putting the development of more cost-effective alternative technologies at risk. A detailed list of the interviews with innovators, energy users and producers can be found at the end of this brief. Annex 4 provides a list of acronyms and abreviations. With major decarbonizing efforts to remove thermal electric power generation and scale up renewable energies, the widespread adoption of energy storage continues to be described as the key game changer for electricity systems. Affordable storage systems are a critical missing link between intermittent renewable power and 24/7 reliability net-zero carbon scenario. Beyond solving this salient challenge, energy storage is being increasingly considered to meet other needs such as relieving congestion or smoothing out the variations in power that occur independently of renewable-energy generation. However, whilst there is plenty of visionary thinking, recent progress has focused on short-duration and battery-based energy storage for efficiency gains and ancillary services; there is limited progress in developing daily, weekly and even seasonal cost-effective solutions which are indispensable for a global reliance on intermittent renewable energy sources. The synthesis of thought leadership interviews and case studies with 37 companies and organizations from 17 countries helped derive the following key takeaways and also provide the impetus to the solution steps that we discuss in detail later in this brief: 1 - Shared road-maps: Energy storage is a well-researched flexibility solution. However, while the benefits of energy storage are clear to the energy community, there has been limited bridge-building with policy-makers and regulators to explore the behavioural and policy changes necessary to encourage implementation. 2 - Market design - Access and stacking: Market access and the ability to stack different services simultaneously will enable cost-effective deployment of energy storage, regardless of the technology. 3 - More than batteries: Energy storage is too often reduced to battery technologies. Future-proofing our energy systems means considering alternative solutions and ensuring technologies have equal market opportunities. Demonstration projects of such technologies are necessary to disprove bias towards specific technologies. 4 - Sector coupling: Energy storage presents a sector coupling opportunity between hard-to-abate sectors, such as mobility and industry and clean electricity. Different vectors of energy can be used, including heat, electricity and hydrogen. 5 - Investment: Relying on investments by adjacent sectors such as the automotive sector is not enough. The energy sector must adopt more aggressively technologies aligned with the end-goal: affordable clean energy for all.
[fr]L'adoption a grande echelle du stockage de l'energie est consideree comme un changement de paradigme majeur pour le systeme energetique. Le developpement d'une technologie de stockage accessible aux consommateurs constitue le chainon manquant pour rendre fiables les energies renouvelables variables. En depit de ce defi technique, le stockage de l'energie peut remplir un role au-dela des energies renouvelables, notamment dans le controle des congestions et les variations de puissance du reseau. Malgre ces perspectives encourageantes, les progres autour du stockage sont restes centres sur les services secondaires et les gains d'efficacite acquis par le stockage a court terme. En revanche, tres peu de progres a ete fait vers les solutions diurnes, hebdomadaires ou saisonnieres rentables, qui sont necessaires a la fiabilite des sources d'energies renouvelables. Conclusions principales: 1 - Feuille de route partagee: le stockage d'energie est une solution de flexibilite reconnue. Cependant, il existe tres peu de visions communes entre legislateurs et experts, bien que tous reconnaissent le potentiel du stockage. 2 - Structure du marche: obtenir un deploiement rentable du stockage se fera grace a un acces equitable au marche et un cumul de differents services, quelle que soit la technologie utilisee. 3 - Au-dela des batteries: le stockage energetique est trop souvent reduit aux batteries. Un systeme energetique a l'epreuve du temps doit s'appuyer sur des solutions diverses, encouragees par un acces equitable aux opportunites sur le marche. 4 - Couplage sectoriel: le stockage energetique represente une veritable opportunite de couplage entre les secteurs difficiles a decarboner et les energies renouvelables. Differents vecteurs d'energie peuvent etre utilises, y compris la chaleur, l'electricite et l'hydrogene. 5 - Investissements: il faut diversifier les investissements au-dela des secteurs adjacents, tel que le secteur automobile. Le secteur energetique doit adopter de maniere plus agressive les technologies alignees avec leur finalite: de l'energie propre pour tous.

[en] After having indicated some key data which illustrate the situation and the predicted evolution of fleets of electrical or hybrid vehicles, and of the number of charge points, this study gives an overview of the strategy and evolving role of car manufacturers in the production of electric and hybrid vehicles, of their components, and in the deployment of associated infrastructures. Thus, it notably describes the various ways car manufacturers adopt to intervene in battery manufacturing either by assembling batteries (purchase of cells, assembling units) or by manufacturing batteries (investment, fabrication unit either owned or shared in partnership). It describes how this commitment in battery manufacturing can have impacts on other battery markets (for grid, industry, building or individual housing), and the various possible strategies (to become a battery provider, to develop partnerships, to commercialise battery packs). The next part addresses the development potential related infrastructures and services associated with e-mobility: manufacturing of charging stations, installation of these stations, operation of a charging station network, proposition of mobility services. The last part indicates how some manufacturers are committed in a global strategy and have created subsidies to be present on very different activity segments which may even reach electricity supply.
[fr]Deux tendances lourdes se degagent actuellement: l'e-mobilite decolle enfin et les reseaux electriques recherchent de la flexibilite (notamment pour pallier l'intermittence de certaines energies renouvelables, en fort developpement actuel et futur). Et ces deux tendances creent des opportunites pour les constructeurs automobiles. L'accroissement des ventes de vehicules electriques pose la question du sourcing des batteries, un composant devenu strategique dans la fabrication des vehicules electriques. Achats massifs a plus ou moins long terme aupres des fabricants asiatiques, assemblage en propre, et, de plus en plus, construction de gigafactories, les strategies different. La plupart des constructeurs automobiles securisent leurs approvisionnements en batteries. Ce qui ouvre de nouveaux horizons, a commencer par le stockage stationnaire y compris, d'ailleurs, avec des batteries de 2nde vie. Soutien au reseau electrique (pour ramener la frequence a 50 Hz), flexibilisation des sites industriels ou encore augmentation du taux d'autoconsommation des batiments/maisons dotes de panneaux photovoltaiques: les developpements possibles sont nombreux. Et il en va de meme pour le smart charging avec un interet mutuel pour les conducteurs de vehicules electriques et les gestionnaires de reseau. Ou encore de l'utilisation de la batterie des vehicules electriques, lorsqu'ils sont a l'arret (V2H, V2B, V2G). Les synergies entre l'automobile et l'electricite se renforcent. A tel point que certains constructeurs automobiles ont saute le pas en devenant fournisseur d'electricite. Volkswagen - via sa filiale Elli - en offre un exemple emblematique. Et il pourrait etre suivi par d'autres comme Tesla prochainement au Royaume- Uni. Tandis que d'autres misent plus sur des partenariats avec les energeticiens. Quelle que soit leur forme, les relations entre constructeurs automobiles devraient a l'avenir nettement s'intensifier.
[en] This document aims at proposing an overview of the legal and regulatory framework which is presently applicable for the installation of solar panels on roofs, and also at presenting some interesting returns on experience, and at formulating recommendations for a good integration of solar energy into the French built heritage. Thus, it first presents the general framework for the installation of solar panels, and then addresses the specific case of installation of solar panels within protected areas (procedure in remarkable patrimonial sites and at the vicinity of historical monuments, in classified buildings or in those classified or registered as historic monuments). Then, the authors discuss the technical characteristics and the integration into building: cost and efficiency of solar panels, examples. Finally, eleven propositions are stated for an easier development of solar installations within the protected heritage. These propositions notably aim at promoting co-construction of projects, at financially valorising the integration of solar panels, and at simplifying procedures for the development of projects
