Zusammenfassung:
Smart second-generation policies for energy transition governance have been less studied and reviewed in the literature. They are also difficult to compare or measure in terms of their effectiveness with regard to the energy transition, not only because each country’s objectives and underlying drivers for an energy transition are different. Technological innovation and new technology deployment are only the tip of the iceberg. Understanding how to redesign energy governance to allow for business model reconfiguration among incumbents and how to stimulate business model innovation by start-ups and new entrants is key for an effective and sustainable energy transition in the long term. However, beyond this, countries must address the underlying driving forces such as consumption patterns and the financial system. Therefore, business model transformation is not the only solution, but it is an important one and it requires well-designed policies. It also requires the involvement of all stakeholders at all levels of the economic fabric of each region and country. At the same time, we continue to measure progress on energy transitions in a superficial and extremely limited way. Policies must now be smarter, not just more ambitious in terms of appearances, and the measurement of energy transition progress must evolve as well. We discuss the full story of an energy transition to the extent possible in a single chapter. For example, we will review business models in different sub-sectors, policies that either block or promote such changes in each sub-sector chosen, and the elements that are necessary for energy transitions to become successful and sustainable without long-term government intervention and financial support. Finally, we also provide insights from an expert workshop held in 2019 and we outline our upcoming work on an Energy Transition Preparedness Index.

À travers le monde, 165 réacteurs sont à l’arrêt définitif et plus d’une centaine d’entre eux devraient arriver en fin de vie dans les prochaines années. De nombreux articles axés sur les aspects socioéconomiques de la fermeture des sites nucléaires ont souligné l’opposition suscitée par la disparition des centrales nucléaires. Toutefois, peu de recherches se sont intéressées à la question de leur reconversion territoriale. Cet article questionne les effets des héritages territoriaux à la lumière des dynamiques de reconversion de deux centrales nucléaires : Brunsbüttel en Allemagne et Barsebäck en Suède. La fermeture et la reconversion de la centrale allemande semblent avoir généré peu de débats socio-territoriaux à l’échelle locale. Au contraire, la centrale suédoise suscite de nombreuses revendications sociopolitiques et des controverses quant à sa reconversion. La comparaison des trajectoires territoriales ces deux centrales nucléaires foncièrement différentes permet ainsi d’enrichir la discussion sur les facteurs qui influencent les trajectoires postnucléaires des territoires.

La méthanisation et le biométhane ainsi produit constituent un potentiel intéressant pour la transition énergétique. Cependant, la variabilité des projets et la multifonctionnalité de la méthanisation complexifient l’analyse et la quantification des impacts environnementaux de la filière, notamment nécessaire à la construction de scénarios prospectifs loco-régionaux. Nous proposons une méthodologie systémique basée sur les flux physiques dont l’application présentée permet la production de facteurs d’émissions territorialisés du biométhane agricole.

The consumption of buildings for the production of heat is expected to decrease in Switzerland in the coming years, in particular following policies encouraging the refurbishment of buildings. This will notably have an impact on the natural gas network, in parallel with the penetration of electric-driven heat pumps. Through a detailed optimization scheme, the evolution of the natural gas (NG) distribution network is studied over a future period of forty years, i.e. up to 2050, on the territory of a large Swiss canton. By way of installing large shares of co-generation units, it is shown that the NG network does not lose its meshed structure, while continuing to play a central role in the production of heat and the generation of part of the additional electricity demand associated with the concomitant penetration of heat pumps. As a novel result, the developed optimization framework allows a detailed, geographically precise view of both the evolution of the NG network, as well as of the optimal location of selected technologies. The adoption of energy networks convergence in urban zones therefore can lead to relevant synergies, avoiding over-investments, increasing system resilience and fostering the use of efficient technologies.

In this chapter, we provide a framework for assessing the relevance and impact of BlockChain technologies for enabling the energy transition from both the production and consumption sides of the equation. We will assess the issues and current solutions to understand how BlockChain combined with Smart Contracting could be best adapted and combined to serve energy transition objectives. The assessment is taken from both the technology and business models perspectives. Our framework is designed as a guide for the adoption and deployment of BlockChain and Smart Contract solutions in the energy sector for common and new use cases by taking the perspective of multiple stakeholders such as consumers (either private and industrial), producers, operators and investors in microgrids, DSOs and TSOs. Moreover, we will include aspects related to regulation and policies. The proposed framework and assessment methodology are the synthesis of a study realized in Switzerland where several representatives of multiple stakeholders have been consulted via interviews and a workshop held in mid-2019.

In Europe, at least 3 GW installed capacity of wind turbine generators (WTG) will fall out of subsidy schemes every year from 2021 onwards. An estimated 50% of this capacity cannot be replaced with new WTG due to commercial and legal restrictions. The remaining options are either to sell the electricity without subsidies on the wholesale electricity market—a novelty for most WTG, as most are receiving a feed-in tariff—or their dismantlement. Since the electricity market fixes the price at the intersection of demand and short run marginal production costs, WTG might struggle to generate enough revenues to cover their costs. This paper proposes an innovative commercialization strategy for WTG after the end of the feed-in tariff, namely a profit-maximized approach that focuses on synergies between revenues and costs when increasing the curtailments of the WTG. The two key elements of this approach are a more flexible and variable cost structure and a central overall optimization process. The paper proves the potential of this new strategy and highlights the necessity of further research for WTG at the end of their lifetime from a technical and commercial perspective, due to the impact on the initial investment decision and best allocation of subsides.

In this paper key applications of blockchain (and smart contracts) are reviewed coming from across different industries around the world, and lessons learned are pulled from this review with a specific focus on what can be learned regarding the energy industry and in relation to the energy transition in particular. While it is difficult to obtain clear conclusions based on such early stage applications in other industrial sectors, like the financial sector, some basic insights emerged that could provide general lessons learned to inform players in the energy industry (in particular utilities and the innovation ecosystem around them) about the potential for blockchain in the energy industry, considering of course that stakeholders in this industry operate and innovate under a highly regulated market.

With the rapid growth and increased consumption of biofuels worldwide, and the multitude of policy decisions supporting this expansion, growing concerns about the biofuels sustainability have arisen. Therefore, the European project “ITAKA”, aiming at supporting the development of aviation biofuels in an economically, socially and environmentally sustainable manner, has devoted considerable effort to take sustainability into account, in a quantitative and qualitative manner. This paper aims to calculate a robust assessment of a life-cycle greenhouse gas (GHG) for the entire ITAKA value chain. Design/methodology/approach – The calculation for the produced bio jet fuel has been set up using the roundtable on sustainable biomaterials (RSB) European Union (EU) renewable energy directive (RED) methodology, through the online RSB tool. This pathway includes feedstock production, feedstock processing, biofuel production, biofuel distillation and all transport steps involved. Findings – A significant reduction in GHG emissions has been demonstrated, up to 66 per cent emission reduction if one considers a mature pathway for the entire ITAKA biofuel chain. Practical implications – The camelina oil produced can be sustainable according to RSB and RSB EU RED schemes if the practices defined in the project are applied. Originality/value – Application of different frameworks (actual vs theoretical) to the ITAKA value chain has aimed at testing and demonstrating the commercial application of the sustainability standards in Europe and the readiness of biofuels in Europe as a major means to decrease GHG emissions in aviation.

Zahlreiche Projekte verfolgen das Ziel, nachhaltigere Städte und Regionen zu erschaffen, insbesondere im Hinblick auf die Energieversorgung. Das Projekt IntegrCiTy kann bei der Evaluierung und später bei der Nutzung von Synergien zwischen den Energienetzen in städtischen Gebieten Unterstützung bieten. Durch die Interoperabilität der Energieinfrastrukturkomponenten werden zweifelsohne eine bessere Effizienz der Energieversorgung, z.B. durch die Förderung von auf Wärme-Kraft-Kopplung basierenden Szenarien, sowie eine Reduktion von Emissionen erreicht. Zudem wird durch die Integration der Netze eine Verringerung bzw. Optimierung der Investitionskosten gewährleistet. Das Projekt IntegrCiTy dient dabei als Interaktionspunkt, zunächst zwischen verschiedenen Energiesektoren, später zwischen allen lokalen Akteuren eines bestimmten Gebiets, bsp. zwischen Industrieunternehmen und Wohnungsgemeinschaften, ohne die politische Ebene ausser Acht zu lassen. Schliesslich wird die Interoperabilität die städtische Infrastruktur robuster machen, weil dadurch die Energieversorgungssicherheit und -vielfalt gesteigert wird. Auch können bestimmte städtische Gebieten energieautonomer werden, da integrierte Energienetze den Beitrag der erneuerbaren Energien und die Rolle der Speicherelemente optimieren.

Hydropower is the central pillar of the current Swiss electricity mix. The Swiss energy transition will profoundly change the electricity mix by transitioning a third of electricity generation from nuclear towards renewable energy sources mainly. This backbone role of hydropower is hindered by the current Europe-wide sluggish economic situation, characterized by subsidized new renewables energies which distort electricity prices, a partially liberalized market and power production overcapacity. In this difficult context, a strong and comprehensive political support through long-term policy will be of utmost importance to accompany hydropower across this transformation. This article explores various subsidy instruments, before using the general framework of “System Engineering” to base a precise recommendation for Swiss hydropower. The recommended mixture of investment contribution with discount reclamation appears the most appropriate instrument. Also, the short time horizon means that the subsidization can be quickly terminated if necessary. In parallel, it is a mature instrument since it is already used for other new renewable energies. The discount model allows reclaiming subsidies in case of an excess profitability. The strength of this study is its robust, comprehensive and allencompassing methodology which can be replicated to other cases (for instance, other technologies or energy sources) and other countries.

Dans le contexte de transition énergétique et de crise environnementale actuel, les intérêts des approches territoriales et systémiques de l’énergie semblent aujourd’hui admis. Cependant et malgré les nombreuses avancées dans les domaines technologiques, en matière d’urbanisme et d’aménagement ou bien encore en termes d’approches psycho-sociales et comportementales, les courbes de consommations énergétiques peinent à s’infléchir. Fort de ce constat, nous posons l’hypothèse, sur la base d’éléments théoriques empruntés à la thermodynamique et à la biologie, du rôle potentiel que pourraient jouer les réseaux de distribution énergétique, leurs caractéristiques, leur morphologie et leur dynamique sur les comportements énergétiques des territoires favorisant ainsi des organisations et des fonctionnements territoriaux énergétiquement plus sobres.

During the IntegrCiTy project, a novel urban energy planning approach was successfully tested. The latter combines stakeholder engagement with an innovative multi-energy model using different control strategies, while combining both energy demand and supply dynamics on selected zones. The applied control strategies applied to the energy networks show the potential gains linked to using synergies among networks and technologies, as to foster renewable energy penetration in the system. Thanks to the combined approach of advanced optimization techniques and stakeholder engagement, solutions can be identified much quicker. In addition, unfeasible solutions can be discarded at earlier stages of the planning process, based on the feedback of the stakeholders even though, from a pure mathematical and energy point of view, the solutions might be theoretically interesting to consider.

The current study presents the CO2-eq emissions of the operational energy use of a single-family house, equipped with a micro-cogeneration unit. A back-up boiler and electricity from the grid cover the remaining energy demand, not covered by the micro-CHP. Two different technologies are evaluated, i.e. ICE and fuel cell systems, operating with a variable share of biomethane, while two different substrates were considered for the biomethane generation. A dynamic LCA was applied for the electricity mix, coming from the grid, using different time steps. The results show that producing biomethane from biowaste compared to conventional natural gas is beneficial, in terms of CO2-eq emissions, independently of the micro-CHP technology, while the total CO2-eq emissions of the fuel cell technology are higher than those of the ICE, independently of the substrate and the biomethane share.

The environmental footprint of the Swiss consumed electricity is not constant over the year. Indeed, the share of the energy production means varies throughout the days, weeks and months, as a function of the electricity demand, resource availability (hydro, solar) and the power plant availability (maintenance). Switzerland also balances its electricity grid with imports from neighboring countries. All these possible fluctuations imply a variable environmental footprint of the Swiss consumed electricity, which affect the environmental impact of the building electricity demand. So far, in Switzerland, the environmental accounting of the building energy demand considers yearly average impacts for the consumed electricity. The EcoDynBat project has developed a framework to collect and merge all the necessary data to conduct a Dynamic Life Cycle Assessment (DLCA) of the environmental impact for the Swiss building consumed electricity under different time steps. The resulting database and methodology has been applied to different profiles of building electricity demand, including buildings with heat pump and/or decentralized electricity production systems. The study evaluates the influence of different time step resolutions on the environmental impacts of the electricity demand in Swiss buildings. Results for the climate change impact show a variability going from 36 to 580 g of CO2 eq/kWh for the consumed electricity when using an hourly resolution, during a one year period. This variability causes an increase in the impacts of up to 24% for space heating, when compared to the annual average impacts. Other electricity loads that do not have a seasonal profile are less affected by the time resolution. Nevertheless, observed trends suggest that an hourly resolution will be relevant to evaluate the potential environmental impacts of smart buildings.
