Abstract anzeigen

El artículo analiza la complejidad de las relaciones en la gobernanza energética en el actual contexto caracterizado por el exceso de oferta y ralentización de la demanda global. El análisis incide sobre el poder como factor determinante en la geopolítica de los precios, las instituciones energéticas, el papel de la oferta y la demanda y los intereses de sus participantes. El análisis se desarrolla desde una perspectiva geopolítica y geoeconómica y, explorando las implicaciones para los principales actores, se apunta que, si bien la bajada de los precios del petróleo puede tener consecuencias significativas, estas no son necesariamente irreversibles.

Abstract anzeigen

Neben kommerziell bereitgestellten Geodaten nehmen freiwillig erhobene geographische Daten (VGI, volunteered geographic information) in der Forschung einen wachsenden Stellenwert ein. Plattformen wie OpenStreetMap (OSM) bieten inzwischen eine enorme Menge an Geodaten, deren Qualität und deren Mehrwert für die Forschung zunehmend kritisch betrachtet werden. Besonders dann, wenn es um räumliche Planung geht, müssen die Daten vor der Anwendung angemessen validiert und bereinigt werden. In diesem Artikel wird ein Datenverarbeitungsmodell vorgestellt, mit dem OSM-Daten so aufbereitet werden können, dass der Bedarf an Ladeinfrastruktur für Elektroautos über von Nutzern eingetragene Point of Interests (POI) räumlich möglichst genau erfasst und abgebildet werden kann. Zunächst erfolgt eine Selektion relevanter Datensets durch eine Prävalidierung. Im zweiten Schritt werden die wichtigsten POI selektiert und spezifiziert. In einem dritten Schritt werden alle OSM-immanenten Schwierigkeiten beseitigt. Das hier vorgestellte Datenverarbeitungsmodell ist auf das Thema Elektromobilität zugeschnitten, für welches POIs in die vier Zeitkategorien Arbeit, Leben, Einkaufen und Freizeit eingeteilt werden, um so den Bedarf an Ladeinfrastruktur zu erheben. Durch dieses Modell der Datenverarbeitung soll die Energienachfrage für Elektroautos räumlich möglichst realistisch dargestellt werden und Rohdaten mit ihren bekannten Fehlern durch den OSM-Datensammlungsprozess bereinigt aufbereitet werden. Anhand einer Fallstudie, die im bayerisch-tschechischen Grenzraum durchgeführt wurde, wird gezeigt, dass die Fehlerrate durch die Implementierung validierter Daten um ca 10% reduziert werden kann.

Arbitrariness in Multidimensional Energy Security Indicators.

In: Ecological Economics (vol. 145) , pg. 263-273

(2018)

DOI: 10.1016/j.ecolecon.2017.09.002

Abstract anzeigen

Energy security (ES) has emerged as an issue of great importance in recent years. Nevertheless, the applied concepts of ES are rather vague and many methodologies have been proposed to construct ES indicators. Among these, composite indicators are very popular despite being affected by several methodological choices that often result in lack of robustness of the rankings involved. From a critical analysis of the methodological characteristic of ES composite indicators this study contributes to the debate on the construction of ES composite indicators by providing a better understanding of the various methods that are available. The analysis frames the ES definitions employed on multidimensional indicators and deals with the methodological implications of including the concept of sustainability.

Cogeneración en Chile: Capacidades, desarrollo y perspectivas.

In: Avances en Energías Renovables y Medio Ambiente (AVERMA) (vol. 22)

(2018)

Abstract anzeigen

En Chile, el proyecto de cogeneración más antiguo data de 1930 y operó hasta el año 1997. Sin embargo, pese a que la tecnología lleva introducida largo tiempo, pocos son los estudios que han analizado el potencial de CHP y su evolución. Un primer paso para el estudio del potencial del país es la creación de un catastro que incluya la capacidad instalada. El interés de este ejercicio radica en el potencial de integración de mayores cantidades de CHP en el sistema eléctrico con el objetivo de hacer frente a la intermitencia de fuentes de energía no convencionales. Además, las plantas CHP pueden ayudar a alcanzar los objetivos de eficiencia energética gracias a la posibilidad de los generadores de volcar a la red tanto la electricidad como calor no consumido en los procesos productivos. Sin embargo, para que esto ocurra es necesario el desarrollo de un marco regulatorio acorde a las capacidades y características de las plantas de CHP. El objetivo de este artículo es precisamente identificar las características de las instalaciones en industrias específicas, así como su evolución, con el objetivo de extrapolar los datos al resto de la economía y obtener un potencial de CHP para el país. Para ello, se han hecho consultas de catastros anteriores, así como entrevistas con empresas para conocer el estado actual del parque de plantas de CHP en el país.

Assessment of on-site steady electricity generation from hybrid renewable energy systems in Chile.

In: Applied Energy (vol. 250) , pg. 1548-1558

(2019)

DOI: 10.1016/j.apenergy.2019.05.005

Abstract anzeigen

Chile has an immense renewable energy potential but its integration into the energy system constitutes a major challenge. The country has a complex topography that is expressed by a divided national grid with almost isolated subsystems and wide differences in the availability of renewable energy resources. The present study aims at evaluating the potentials of combining solar power, wind power and storage systems to provide steady loads already from the generation source. The analysis relies on an optimization model to size hybrid renewable energy systems and 10 years of weather data from the brand new ERA5 global reanalysis. Multiple scenarios are calculated and intercompared for all possible locations across the country. These scenarios include system sizing considering hourly weather data for the period 2008–2017 and for one year without major weather extreme events. In both analyses, the results are calculated for systems that generate 1 MWh of electricity at every time step and systems that have certain intraday flexibility. Results show that the necessary generation and storage capacities to provide a steady energy output are very high even for areas with exceptionally high renewable energy potential (in the Atacama desert the system configuration requirements could reach 10 MWp of photovoltaics and 10 MWh of storage). Intraday flexibility has direct effects on these results by reducing the total size of the systems but the effects on the sizes of the installations of the particular technologies depend on the individual geographical location.

Potential Analysis of Hybrid Renewable Energy Systems for Self-Sufficient Residential Use in Germany and the Czech Republic.

In: Energies (vol. 12) , pg. 4185

(2019)

DOI: 10.3390/en12214185

Abstract anzeigen

Independence from the power grid can be pursued by achieving total self-sufficient electricity supply. Such an energy supply model might be particularly interesting for settlements located in rural areas where enough space is available for energy generation installations. This article evaluates how and at what cost electricity demand of residential users across Germany and the Czech Republic could be covered by hybrid renewable energy generation systems consisting of photovoltaics, micro-generation wind turbines and batteries. High-resolution reanalysis data are used to calculate necessary system sizes over a large area by simultaneously accounting for the temporal variability of renewable energy. For every potential location in the research area, the hybrid system requirements for clusters of 50 self-sufficient single-family houses are calculated. The results indicate no general trend regarding the size of the respective technologies, although larger areas where PV-wind power complementarity enables lowering the total system costs and required storage capacities were determined. Assuming that the cluster of households could be constituted and depending on the location, the total installation and operation costs for the proposed systems for a lifetime of 20 years range between EUR 1.8 Million and EUR 5 Million without considering costs of financing. Regions with the lowest costs were identified mainly in the south of Germany.

Gestión de la Demanda en la Industria de Chile: Aprendiendo del Caso Alemán (Demand Side Management on the Chile Industry: Learning From the German Case).

In: Ingeniería (vol. 24)

(2019)

DOI: 10.14483/23448393.14709

Abstract anzeigen

Context: Both pioneer countries and those that have recently begun an energy transition towards renewable energy require high levels of flexibility in their electrical systems. This article reviews the Demand Side Management (DSM) application as a tool to provide flexibility, and then, to achieve renewable energy penetration objectives. Method: A systematic mini-review of the literature has been done to review the origin and evolution of the concept of DSM in German and Chilean industry, at the same time, to make a parallel and comparison between them. Results: Both countries have difficulties in taking advantage of the demand management potential in the industry, the lack of promoting policies and the lack of specific regulatory frameworks are some of the causes. Conclusions: It is necessary to speed up attention to the management of demand, it is important that the academy contributes with estimates of potential, it also needs public policies that encourage the use of this tool.

Industry, flexibility, and demand response: Applying German energy transition lessons in Chile.

In: Energy Research & Social Science (vol. 54) , pg. 12-25

(2019)

DOI: 10.1016/j.erss.2019.03.003

Abstract anzeigen

Demand side management (DSM) contributes, among its other purposes, to provide stability and flexibility to energy systems that include a high proportion of variable renewable energy in pioneer countries and those which recently began their energy transition. Among DSM policies, implementation of measures and mechanisms for a demand response (DR) is not a trivial matter. This study presents a review and comparative analysis of the major energy policy developments in Germany and Chile. Based on i) the relevance of the industry sector in both countries, ii) the difficulty in implementing the regulatory framework and iii) the importance given to the industrial customers in the German legislation and DR literature, the following analysis will focus on both medium and large industrial customers. The goals are to review the challenges in untying the full DR potential of the productive industry and to provide recommendations for the promotion of DR in Chile. Emphasis is placed on the lessons learned in fitting the wide potential of DR in the German electricity markets. A review of the successes and failures of the German experience reveals the potential risk that poor policy implementation can have in both the short and long term.

A framework for regional smart energy planning using volunteered geographic information.

In: Advances in Geosciences (vol. 54) , pg. 179-193

(2020)

DOI: 10.5194/adgeo-54-179-2020

Abstract anzeigen

This study presents a framework for regional smart energy planning for the optimal location and sizing of small hybrid systems. By using an optimization model – in combination with weather data – various local energy systems are simulated using the Calliope and PyPSA energy system simulation tools. The optimization and simulation models are fed with GIS data from different volunteered geographic information projects, including OpenStreetMap. These allow automatic allocation of specific demand profiles to diverse OpenStreetMap building categories. Moreover, based on the characteristics of the OpenStreetMap data, a set of possible distributed energy resources, including renewables and fossil-fueled generators, is defined for each building category. The optimization model can be applied for a set of scenarios based on different assumptions on electricity prices and technologies. Moreover, to assess the impact of the scenarios on the current distribution infrastructure, a simulation model of the low- and medium-voltage network is conducted. Finally, to facilitate their dissemination, the results of the simulation are stored in a PostgreSQL database, before they are delivered by a RESTful Laravel Server and displayed in an angular web application.

    Unveiling the potential for combined heat and power in Chilean industry-A policy perspective.

    In: Energy Policy (vol. 140) , pg. 111331

    (2020)

    DOI: 10.1016/j.enpol.2020.111331

    Abstract anzeigen

    Combined Heat and Power (CHP) has again become a key element in international energy and environmental policy, since it is one of the most promising methods of ensuring grid stability, making an energy system more flexible and environmentally friendly. This is particularly true in the case of Chile, which has an energy system that progressively introduced volatile renewable energy sources such as wind and solar energy. This scenario has led to the development of a new regulatory strategy and CHP flagship projects throughout the country. Despite this interest, there has been no analysis of CHP development or the impact of the latest regulatory changes on its evolution. This study presents an updated cadastre of the CHP facilities as of 2018, together with an analysis of its evolution in terms of an energy policy. From this cadastre, interviews with experts, and a review of the regulations and incentives, the study identifies the main policy barriers for CHP development in Chile. Furthermore, this study presents a series of challenges and recommendations for the country.

    Prioritizing the Chicken or Egg? Electric Vehicle Purchase and Charging Infrastructure Subsidies in Germany.

    In: Politics and Governance (vol. 8) , pg. 185-198

    (2020)

    DOI: 10.17645/pag.v8i3.3025

    Abstract anzeigen

    To meet current targets for greenhouse gas emissions in Europe, emissions, especially those originating from the road transport sector, need to be reduced. Plans are to achieve this goal by substituting fossil fuel vehicles with electric vehicles (EVs). This article first discusses conceptually the impact of an increasing share of EVs on the electricity grid and suitable locations for charging stations with examples from a Case Study in Lower Bavaria. Secondly, the impact of purchase subsidies on EV purchases in Germany, a high-income country characterized by an important automotive industry and an increasing share of private vehicles is examined. To achieve this, yearly information on EV purchases were analyzed by applying the Synthetic Control Method. Combining data from different sources including the European Alternative Fuels Observatory, Eurostat, and the European Automobile Manufacturers' Association, an overall picture was developed. Results indicate a difference between private, semi-public, and public charging infrastructures. Its spatial distribution does not correspond to a specific development strategy. Moreover, EV subsidies have a limited effect in Germany when controlling for market size. Limiting the discussion to a trade-off between subsidizing infrastructures or EV purchases obviates the multidimensionality of the problem as neither of them may be sufficient to accelerate the transition per se. Furthermore, if electricity provided for EVs comes mainly from fossil carriers, the changes in the road transport sector will not yield the expected emission reductions. The transition towards renewables is directly intertwined with the effects of EVs on emission reductions in the road transport sector.

    The data set includes hourly time series for a period of one year of electricity demand of three different types of industries. The industries include a small food processing company, one small paper industry and one medium-large paper producing company. The data have been synthetized from two years of measured data from industries in Chile using a comprehensive clustering analysis. The synthetic data possess the same statistical characteristics as the measured data but are provided normalized to one kWh and anonymized in order to be used without confidentiality issues. The data were originally used in the associated paper [1] to assess the demand side management potential of the industries but these can be used for further energy system modelling exercises including these types of industries.

    DOI: 10.1016/j.energy.2020.118962

    Abstract anzeigen

    Demand side management is a promising alternative to offer flexibility to power systems with high shares of variable renewable energy sources. Numerous industries possess large demand side management potentials but accounting for them in energy system analysis and modelling is restricted by the availability of their demand data, which are usually confidential. In this study, a methodology to synthetize anonymized hourly electricity consumption profiles for industries and to calculate their flexibility potential is proposed. This combines different partitioning and hierarchical clustering analysis techniques with regression analysis. The methodology is applied to three case studies in Chile: two pulp and paper industry plants and one food industry plant. A significant hourly, daily and annual flexibility potential is found for the three cases (15% to 75%). Moreover, the resulting demand profiles share the same statistical characteristics as the measured profiles but can be used in modelling exercises without confidentiality issues.

    DOI: 10.1016/j.erss.2021.102090

    Abstract anzeigen

    The multilateral institutions of global energy governance consider energy security a key aspect for achieving greater coordination in the energy transition. However, the public good characteristics of energy security and its implications for global energy governance have not been systematically analyzed. This article discusses the concept of energy security within the global energy governance literature and the public character of the “energy regime complex” in the area of energy security. We define the requirements for considering energy security as a global public good. Then, we apply this theoretical framework and assess the levels of publicness of consumption, benefits, and decision-making of the various global energy security approaches. The results show that institutional arrangements for the governance of the security of supply and demand should be conceptualized as transnational public goods rather being considered within a more global cooperative energy security approach. We discuss the implications of the results for other global energy governance domains, finding that the extension of the public character of energy security may limit coordination in other areas of energy governance, such as climate change mitigation.

    Energy Cell Simulation for Sector Coupling with Power-to-Methane: A Case Study in Lower Bavaria.

    In: Energies (vol. 15) , pg. 2640

    (2022)

    DOI: 10.3390/en15072640

    Abstract anzeigen

    In this study, the possibility of sector coupling with biological Power-to-Methane to support and stabilize the energy transition of the three major sectors of electricity, heat, and gas was addressed. For this purpose, the energy cell simulation methodology and the Calliope tool were utilized for energy system optimization. This combination provides detailed insights into the existing dependencies of consumers and fossil and renewable energy suppliers on a local scale. In this context, Power-to-Methane represents an efficient technology for quickly and effectively exploiting unused electricity potential for various sectors and consumers. It was found that, even in regions with low wind levels, this surplus electricity potential already exists and depends on various influencing factors in very different ways. The solar influence on these potentials was considered in connection with gas-fired cogeneration plants for district heating. It was found that the current heat demand for district heating produces a large amount of electricity and can generate surplus electricity in the winter. However, in the summer, large amounts of usable waste heat are dissipated into the environment, owing to the low consumption of district heat. This problem in the heat sector could be reduced by the expansion of photovoltaics, but this would require further expansion of storage or conversion systems in the electricity sector. This demonstrates that the consideration of several sectors is necessary to reflect the complexity of the sector coupling with Power-to-Methane properly.

    Socio-Ecological Controversies from Chilean and Brazilian Sustainable Energy Transitions.

    In: Sustainability (vol. 15) , pg. 1861

    (2023)

    DOI: 10.3390/su15031861

    Abstract anzeigen

    Chile and Brazil have been historically recognised in South America for having a high share of renewable sources in their primary energy matrices. Furthermore, in the last two decades, aligned with the global efforts to conduct a sustainable energy transition, both countries have experienced a successful introduction of nonconventional renewable energy for power production. Nevertheless, some experiences with renewable sources have been demonstrated to be not entirely societally and environmentally friendly, as some local human communities and ecosystems are threatened, and conflicts have emerged, regardless of low-emission technology. Using the cases of Chile and Brazil, we aim to explore the socio-ecological dimension of sustainable energy transition—which has sometimes been ignored. We analyse the controversies regarding renewable energy and the emergence of socio-ecological conflicts through the principles of justice in transitions. Critical renewable conflicting power projects are identified using the Atlas of Environmental Justice’s database. Considering those experiences, we believe that reinforcing decision-making processes should be in synergy with identifying new alternatives to develop energy in both countries. Placing justice approaches at the centre of public policies is imperative to developing sustainable policies in the future.

    Assessment of the green hydrogen value chain in cases of the local industry in Chile applying an optimization model.

    In: Energy (vol. 300) , pg. 131630

    (2024)

    DOI: 10.1016/j.energy.2024.131630

    Abstract anzeigen

    This study assessed the feasibility of integrating a green hydrogen value chain into the local industry, examining two case studies by comparing four scenarios. The optimization focused on generating electricity from stationary renewable sources, such as solar or through Power Purchase Agreements, to produce sufficient hydrogen in electrolyzers. Current demand profiles, renewable participation targets, electricity supply sources, levelized costs of energy and hydrogen, and technology options were considered. The most cost-effective scenario showed a levelized cost of energy of 0.032 and 0.05 US$/kWh and a hydrogen cost below 1.0 US$/kgH2 for cases 1 and 2, respectively. A sensitivity analysis highlighted the critical influence of fuel cell technology on cost modification, underscoring the importance of focusing cost reduction strategies on these technologies to enhance the economic viability of the green hydrogen value chain. Specifically, a high sensitivity towards reducing the levelized costs of energy and hydrogen in the port sector with adjustments in fuel cell technology costs was identified, indicating the need for specific policies and supports to facilitate their adoption.

    Parameterization proposal to determine the feasibility of geographic areas for the green hydrogen industry under socio-environmental and technical constraints in Chile.

    In: International Journal of Hydrogen Energy (vol. 50) , pg. 578-598

    (2024)

    DOI: 10.1016/j.ijhydene.2023.10.013

    Abstract anzeigen

    Chile, abundant in solar and wind energy resources, presents significant potential for the production of green hydrogen, a promising renewable energy vector. However, realizing this potential requires an understanding of the most suitable locations for the installation of green hydrogen industries. This study proposes a quantitative methodology that identifies and ranks potential public lands for industrial use, based on a range of technical parameters (such as solar and wind availability) and socio-environmental considerations (including land use restrictions and population density). The results reveal optimal locations that can facilitate informed, sustainable decision-making for large-scale green hydrogen implementation in Chile. While this methodology does not replace project-specific technical or environmental impact studies, it provides a flexible, general classification to guide initial site selection. Notably, this approach can be applied to other regions worldwide with abundant solar and wind resources, such as Australia and Northern Africa, promoting more effective and sustainable global decision-making for green hydrogen production.

    Socio-environmental and technical factors assessment of photovoltaic hydrogen production in Antofagasta, Chile.

    In: Energy Strategy Reviews (vol. 53) , pg. 101373

    (2024)

    DOI: 10.1016/j.esr.2024.101373

    Abstract anzeigen

    This study introduces a method for identifying territories ideal for establishing photovoltaic (PV) plants for green hydrogen (GH ) production in the Antofagasta region of northern Chile, a location celebrated for its outstanding solar energy potential. Assessing the viability of PV plant installation necessitates a balanced consideration of technical aspects and socio-environmental constraints, such as the proximity to areas of ecological importance and indigenous communities, to identify potential zones for solar and non-conventional renewable energy (NCRE)-based hydrogen production. To tackle this challenge, we propose a methodology that utilizes geospatial analysis, integrating Geographic Information System (GIS) tools with sensitivity analysis, to determine the most suitable sites for PV plant installation in the Antofagasta region. Our geospatial analysis employs the QGIS software to identify these optimal locations, while sensitivity analysis uses the Sørensen–Dice coefficient method to assess the similarity among chosen socio-environmental variables. Applying this methodology to the Antofagasta region reveals that a significant area within a 15 km radius of existing road networks and electrical substations is favorable for photovoltaic projects. Our sensitivity analysis further highlights the limiting effects of socio-environmental factors and their interactions. Moreover, our research finds that enlarging areas of socio-environmental importance could increase the total hydrogen production by about 10% per commune, indicating the impact of these factors on the potential for renewable energy production.
