In Italy, the actual geothermal concessions for the use of the geothermal resources expire in 2024. By the forthcoming assignment of the mining rights participate ‐ beyond ENEL‐Greenpower – also players of the free market, who intend to apply new technologies, accessing, however, one and the same geothermal reservoirs of Larderello‐Travale and Mt. Amiata. The use of different methodologies (partial or complete reinjection), in adjacent areas, requires an advanced monitoring system, capable to locate microseismicity in real‐time, calculating the relevant seismic parameters and communicating the results in quasi‐real‐time to the involved concessions, the competent authorities and the population. Following the initiative of the “Regione Toscana”, the role as responsible monitoring agency (SPM) has been assigned to INGV, with the purpose to guarantee a homogeneous and centralized monitoring of all concessions operating in the Tuscan geothermal areas. Concerning power plants under national jurisdiction, the ministerial guidelines propose an experimental alert‐ and reaction‐scheme, for water reinjection, exclusively. In this perspective, it is important to stress the actual lack of specific guidelines for geothermal exploitation on regional level. The aim of the present work is to summarize the experiences collected during the management of geothermal systems in other countries and to promote the drafting of a document that defines an appropriate communication scheme for application of the monitoring tasks by the SPM. Such a scheme may represent the basis for developing a reaction scheme and could be useful for the implementation of future regional monitoring guidelines for geothermal activities., In Italia, le attuali concessioni per l’utilizzo delle risorse geotermiche scadranno nel 2024. Alla prossima aggiudicazione parteciperanno - oltre ENEL-Greenpower – anche soggetti del mercato libero, che potrebbero voler applicare nuove tecnologie, attingendo comunque con alta probabilità ai medesimi reservoir geotermici dei campi di Larderello-Travale e del Monte Amiata. L’utilizzo di metodologie differenti (reiniezione parziale o totale), applicate in aree adiacenti, richiede un sistema di monitoraggio avanzato, in grado di localizzare in tempo reale la microsismicità, calcolare i parametri sismici rilevanti e comunicare, in tempo quasi-reale, i risultati ai concessionari coinvolti, agli uffici competenti e alla popolazione. Su iniziativa della Regione Toscana è stato assegnato all’INGV il ruolo di SPM (Struttura Preposta al Monitoraggio) con l’obbiettivo di garantire un monitoraggio omogeneo e centralizzato per tutte le concessioni attive nelle aree geotermiche toscane. Per impianti di competenza nazionale, le linee guida ministeriali propongono uno schema sperimentale di allerta e di reazione per il solo caso di reiniezione di acque nel sottosuolo. In tale contesto è importante notare l’attuale mancanza di linee specifiche per l’utilizzo della risorsa geotermica a livello regionale. L’obiettivo del presente documento è di riassumere le esperienze raccolte nella gestione di impianti geotermici in altri Paesi e di incentivare la redazione di un documento che definisca un apposito schema di comunicazione da applicare al monitoraggio da parte della SPM. Tale schema può rappresentare la base di partenza per lo sviluppo di un protocollo di reazione e potrà essere utile per l’implementazione delle future linee guida regionali per il monitoraggio delle attività geotermiche.

ilustraciones, fotografías, graficas, mapas Esta tesis revisa nueva información, datos geológicos y geofísicos existentes y de código abierto del flanco occidental del sistema volcánico Nevado del Ruiz (NRV), concretamente dentro de los valles de Molinos/Rio Claro. Estos conjuntos de datos heredados, que datan de hace más de cincuenta años, se revisan en el contexto de los nuevos datos de los últimos diez años. Las interpretaciones actuales se discuten a la luz de las interpretaciones pasadas. La intención es examinar la eficacia del uso de datos "antiguos" existentes y determinar si dichos datos se ajustan a la comprensión actual en el marco de la exploración geotérmica comercial. En los datos estudiados se incluyen nuevos datos magnetotelúricos de baja frecuencia recopilados en 2013. Además, las ubicaciones de las manifestaciones geotérmicas superficiales (como fumarolas, aguas termales y otros fenómenos) se correlacionan cualitativamente con los datos y la interpretación. Por último, se desarrolla y presenta un modelo 2D. (Texto tomado de la fuente) This thesis reviews existing and open-source geological and geophysical data from the western flank of the Nevado del Ruiz (NRV) volcanic system, namely within the Molinos/Rio Claro Valleys. These legacy data sets, which date back more than fifty years, are reviewed within the context of new data from the last ten years. Current interpretations are discussed in light of past interpretations. The intent is to examine the efficacy of using existing, “old” data, and to determine whether such data fit current understanding in the framework of commercial geothermal exploration. Various data sets are examined, including new low-frequency magnetotelluric data collected in 2013. Further, locations of surface geothermal manifestations (such as fumaroles, hot springs, and other phenomena) are qualitatively correlated with the data and interpretation. Lastly, a 2D model is developed and presented. Maestría Magíster en Ciencias - Geología Geotermia

The Valence basin is a graben located in the Rhodanian corridor which belongs to the ECRIS system, and is the subject of many studies due to its geothermal potential. In response to its a multiphase history, fracture networks of the basement and sedimentary cover which are targeted for geothermal exploitation show a complex organization. This study aims to characterize facture networks organization in the Valence basin. It is based on seismic and borehole data in the basin, as well as geological maps, digital elevation model (DEM) and outcrops on the Ardèche margin. Two methodological studies were developed to characterize the orientation and length distributions. These methods allowed to determine fracture network modelling parameters, and highlighted a structural heritage but also a detachment between the basement and the cover.; Le bassin de Valence, un fossé d’effondrement appartenant au système ECRIS localisé le long du couloir Rhodanien, est l’objet d’études approfondies quant à son potentiel géothermique. Dû à l’histoire évolutive polyphasée du bassin, les réseaux de fractures du socle et de la base de la couverture sédimentaire ciblés pour l’exploitation géothermique présentent une organisation complexe. Cette étude vise donc à caractériser l’organisation du bassin de Valence et de ces réseaux de fractures. Elle s’appuie sur les données sismiques et de forages du bassin, ainsi que les cartes géologiques, le modèle numérique du terrain et des affleurements de la marge ardéchoise. Deux méthodes de caractérisation des orientations et des longueurs des fractures sont développées dans ce travail. Leur application a permis de déterminer les paramètres des modèles de réseaux de fractures, et a mis en évidence un fort héritage structural mais aussi un découplage du socle et de la couverture.

Geothermal energy has a huge potential in building applications. This paper proposes the use of an Air-Source Heat Pump (ASHP) system coupled with a Horizontal Earth-To-Air Heat Exchanger (EAHX) to reduce energy consumption in buildings. The novelty is to geothermally pre-heat or pre-cool the air source of the ASHP through the EAHX, reducing the electric power needed, keeping constant heating/cooling capacity. The behaviour of ASHP-EAHX system has been investigated by a numerical model implemented in TRNSYS. A total of 54 combinations have been obtained and tested varying ground thermal properties, burial depth, air flow rate and pipe length. The model has been validated with a real case showing a good agreement between simulated and monitored data. The study is focused on the city of Turin (North of Italy), compared with Brindisi (South of Italy), and extremely cold and hot climates like Tromso (Norway) and Bechar (Algeria), respectively. The ASHP-EAXH performance has been investigated, by the comparison with the traditional ASHP, using different coefficients, such as the Coefficient of Performance (COP), the Energy Efficiency Ratio (EER), the Seasonal Coefficient of Performance (SCOP), and the Seasonal Energy Efficiency Ratio (SEER). The paper reveals how the ASHP-EAHX system show higher performance compared to the traditional ASHP, in all seasons. The overall merit is, for cold extremely climate, the reduction of the shutdown periods, when the outside temperature is below the limit operating temperature, and to allow the extension of the use of the heat pump to locations, where it is currently not convenient for the average outside temperature lower than the limit operating temperature of the heat pump.

Une étude géochimique a été effectuée sur l’eau d’une source géothermale appelé Lilida, située dans la province de l’Ituri, dans la partie nord-est de de la République Démocratique du Congo. Ses objectifs étaient de définir le faciès chimique de ladite eau, de déterminer la nature lithologique de son réservoir et d’estimer la température qu’elle possède dans son réservoir. Les échantillons d’eau ont été prélevés au mois de février de l’année 2017 et soumis à des analyses chimiques et physiques. En plus, les diagrammes de D’Amore et al. (1983), de Giggenbach (1991) et de Piper (1944) ont été élaborés pour obtenir la classification de cette eau thermale. Au terme de cette étude, l’eau de la source Lilida s’est révélée du type bicarbonaté calcosodique. Son facies géochimique étant pour les cations Na+ > Ca2+ > Mg2+ et pour les anions HCO3->SO4=>Cl-. Il s’est avéré que son réservoir était une formation argileuse peu profonde contenant certainement des calcaires dolomitiques et des dérivées des flyschs ou « volcanites ». L’application de la géothermométrie a révélé que l’eau étudiée aurait, dans son réservoir, une température de 45,7 °C. En tant que telle, elle ne peut faire objet que d’une exploitation géothermique basse énergie., A geochemical survey on the thermal water released by the Lilida Spring, located in the Congolese Northeastern Province of Ituri was undertaken. The aims of this study were to determine the chemical facies of this water; to determine the lithological nature of its reservoir and to predict its subsurface temperature. The water samples were collected in February 2017. Then physical and chemical analyzes were done. The graphics of D’Amore, Giggenbach and Piper were applied on the water analyzes to obtain its classification. The studied water was characterized as a bicarbonated calcosodic shallow fresh groundwater, with this following geochemical facies for the cations Na+ > Ca2+ > Mg2+ and this one for the anions HCO3->SO4=>Cl-. Its reservoir was characterized as an argillaceous formation containing certainly dolomitic limestone and flysch derivate or «volcanites». Assessments from chemical geothermometer suggest the existence of a peripheral geothermal reservoir of low enthalpy (45.7 °C). Thus, in that state, this thermal water can only be used for geothermal low energy exploitation.

International audience; We investigate the feasibility of the hybrid gravity technique applied to two geothermal reservoirs in northern Alsace, France, namely the Soultz-sous-Forêts and Rittershoffen sites. Soultz-sous-Forêts site is the first enhanced geothermal system demonstration site producing electricity in France. Here a geothermal fluid at 165 °C allows to produce around 1.5 MW thanks to one injection well and one production well 5 km deep. Rittershoffen site is dedicated to an industrial use and it is designed to produce 24 MWth heat power with 2 wells around 2.5 km deep. The most recent production episodes of Rittershoffen and Soultz-sous-Forêts geothermal plants have started respectively on May and June 2016. To study underground mass redistribution, time-lapse relative microgravity measurements have been done since 2014 on a network designed ad hoc for Soultz-sous-Forêts site and since 2015 for Rittershoffen site. After tide and drift correction, double differences are calculated to retrieve the gravity variation at each measuring point compared to a reference time and station. Absolute gravity measurements have been also collected at one of the reference stations. Before the beginning of the production in 2016, the stability of the Soultz-sous-Forêts reference station was monitored through the repetition of absolute measurements and continuous gravity records. In 2016, regular ties between the reference stations and the Strasbourg gravity observatory STJ9 have been done. Several superconducting gravimeters operate continuously in STJ9. Thus, we approach the concept of hybrid gravity. Vertical deformation is also controlled thanks to six continuous GPS measurements: the height changes are less than 1 cm. So we consider that our gravity variations are only due to subsurface mass changes. For the Soultz-sous-Forêts network, we notice significant changes in agreement with the position of the injection and the production wells. The maximum gravity change is 31 ± 8 μGal. On the contrary, we do not detect any similar signal for the Rittershoffen network. A simplistic model using two spherical sources located at 5 and 2 km for Soultz-sous-Forêts and Rittershoffen sites respectively shows negligeable surface gravity changes when taking into account the known injection and production flow rates.

[EN] The 83 ASTER L1B thermal channels of Cuban territorial scenes, from 2000 to 2008 years, selected and processed with geothermal aims showed almost 50% of cloudy coverage. The vortex coordinated as well as other data from such metadata facilitated completing the designed database. From a preliminary mosaic with the images existent these were subsequently processed in order to obtain temperature images. Such images were then integrated into another mosaic with a suitable reclassification resulting in 11 classes with 3°C each. This allowed delimitating those anomalous zones where the greater distribution of pixels oscillated from 25°C to 37°C, and the cloudy coverage temperature aroused up to 20°C approximately. In the resulting temperature map, 69 polygons were a priori delimitated and categorized, as for their perspective and the temperature value above 40°C. These polygons were later overlapped to Google Earth images with the aim to identify those from anthropogenic origins. Finally it was obtained an estimation of the temperature value of the surface coverage of the national territory as well as the understanding of that the eastern zone is the most perspective. This is an experimental application, using satellite images ASTER L1B with geothermic purpose., [ES] Se seleccionaron y procesaron, para fines geotérmicos, 83 escenas de las bandas termales pertenecientes al canal térmico del sensor ASTER L1B, de los años 2000 a 2008, con un cubrimiento nuboso de casi un 50%. Las coordenadas de los vértices de las imágenes, así como otros datos provenientes de sus metadatos, ayudaron al completamiento de la base de datos diseñada. Se preparó un mosaico preliminar a partir de las imágenes existentes en el país. Las nuevas imágenes, con valor de temperatura, fueron georreferenciadas según el sistema de coordenadas nacional Cuba Norte y se unificaron en otro mosaico para dicha variable. Como resultado, se establecieron 11 clases, divididas aleatoriamente cada 3°C, que ayudaron a delimitar las zonas anómalas donde la mayor distribución de píxeles oscila entre 25°C-37°C; la temperatura de la cobertura nubosa llegó hasta 20°C, aproximadamente. Sobre la imagen clasificada se definieron 69 polígonos, según su grado de perspectividad y con valor de temperatura superior a 40°C, lo cual se corresponde con la baja entalpía (25°C-100°C) que es la de mayor probabilidad en el país. Las imágenes obtenidas fueron superpuestas sobre la del Google Earth, con el fin de discernir la relación entre la cobertura terrestre y su origen antropogénico. Finalmente, se obtuvo una estimación del valor de temperatura de la cobertura terrestre del territorio nacional, lo que permitió definir que la zona oriental es la más perspectiva. Este trabajo constituye una aplicación experimental de las imágenes satelitales ASTER L1B con fines geotérmicos.

Geothermal energy has become one of the recognized processes to supply energy and to stop significantly the emission of greenhouse effect gases in the atmosphere. This classical renewable energy consists to extract thermal energy into the Earth and to produce heat, cooling and/or electricity. But particularly for the last case, only a few places in the world can exploit it. Indeed, the geothermal reservoir must be permeable and easily accessible.The subduction setting of the Lesser Antilles is favorable to the presence of geothermal reservoirs but its insularity and its volcanic nature have a negative impact on the exploration phases. The influence of the sea on electromagnetic methods, dense bush and the strong urban development add other obstacles. Thus, the risk of failure increases. Consequently, the localization and the characterization of the geothermal reservoir must be more precise. Facing these many constraints, it is essential to apply adapted methodologies and to build the best conceptual model as possible.The coupling of numerical models is presented and applied to the low enthalpy geothermal system of Lamentin, in Martinique. This approach could be developed for other countries with the same geodynamical context. The Geomodeller software and the ComPASS Code are the two numerical tools which have been employed to generate a 3D geological model then to simulate the hydrothermal aspect.The building of the 3D model gives elements of knowledge and thinking about the geothermal system of Lamentin and the hydrothermal simulations suggest some hypothesis on the localization and the intensity of the heat source., La géothermie est devenue aujourd’hui l’une des solutions pour produire de l’énergie tout en limitant significativement les émissions de gaz à effet de serre dans l’atmosphère. Cette énergie de base renouvelable qui exploite la chaleur souterraine présente de nombreuses utilisations comme la production de chaleur, de froid et/ou d’électricité. Cependant la facilité d’accès à cette ressource n’est pas la même partout et seuls quelques sites privilégiés sont recensés dans le monde. Le réservoir géothermique doit en effet être perméable et facilement accessible.Les îles des Petites Antilles s’inscrivent dans un contexte géologique de subduction favorable à l’existence de réservoirs géothermiques. Toutefois, l’insularité et le caractère volcanique complexifient l’exploration qui nécessite des échelles spatiales plus fines. À ces difficultés s’ajoutent la proximité de la mer qui perturbe notamment les méthodes électromagnétiques, la végétation dense favorisée par le climat tropical et la forte urbanisation.Face à ces nombreux obstacles, il est indispensable d'appliquer des méthodologies adaptées qui aboutissent à l'élaboration de modèles conceptuels les plus complets et surtout les plus fiables possibles. La modélisation numérique peut y apporter une grande fiabilité et réduire ainsi le risque géologique.Une méthodologie de couplage de modèles numériques est présentée et appliquée au prospect géothermique du Lamentin en Martinique, mais vise à être adaptée aux autres îles des Petites Antilles, voire à d’autres zones insulaires et volcaniques. Le logiciel Geomodeller et la plateforme ComPASS sont les deux outils numériques qui ont été employés pour générer un modèle géologique 3D et pour y réaliser des simulations hydro-thermiques. La construction du modèle 3D apportera des éléments de compréhension et de réflexions sur la structure et le fonctionnement du système géothermique du Lamentin. La comparaison des géothermes obtenus par simulation hydro-thermique avec ceux mesurés dans les forages d’exploration profonde permettront d’éprouver certaines hypothèses sur la localisation et l’intensité de la source de chaleur responsable de l’activité hydrothermale du Lamentin.

Diese Diplomarbeit setzt sich mit dem Thema der Verwendung und Förderung von alternativen Energieversorgungssystemen für Einfamilienhäuser auseinander. Der Begriff Nachhaltigkeit ist im Zusammenhang mit dieser Arbeit sehr wichtig. Daher wird dieser auch im Allgemeinen sowie im Zusammenhang mit der Bauwirtschaft bzw. für Privathaushalte genauer erläutert. Um dem Gedanken der Nachhaltigkeit gerecht zu werden, ist eine Energiegewinnung aus erneuerbarer Energie unumgänglich. Unter Auflistung aller erneuerbaren Energiequellen werden die entsprechenden Vor- bzw. Nachteile im Zusammenhang mit der Energiegewinnung aufgezeigt. Um bei der Errichtung eines Eigenheims die richtigen Entscheidungen im Hinblick auf Klimaaspekte treffen zu können, wird das Aktivitätsfeld „Bauen und Wohnen“ der österreichischen Klimawandelanpassungsstrategie genauer erläutert. Alle Formen der nachhaltigen Energiegewinnung für ein Einfamilienhaus werden detailliert beschrieben und ermöglichen somit eine Vergleichsbasis gegenüber Energiegewinnungssystemen aus fossilen Ressourcen. Es werden alle notwendigen Informationen für die Anschaffung, Planung, Montage und den Betrieb der Anlagen dargestellt. Der augenscheinliche Vergleich unter den alternativen Energiegewinnungssystemen wird durch die Auflistung der Investitions-, Heiz- und Wartungskosten sowie der Amortisationszeit geschaffen. In Zusammenhang mit den Fördermitteln, die vom Bund und den Ländern bereitgestellt werden, kann eine sehr aussagekräftige Empfehlung für das, zum Zeitpunkt dieser Arbeit geltende, günstigste sowie effizienteste alternative Energiesystem gemacht werden. In weiterer Folge wird die Marktentwicklung der letzten Jahre analysiert sowie die entsprechenden Zukunftsprognosen abgegeben. Das Ziel der vorliegenden Arbeit ist es somit Überblick über das derzeitige Angebot an alternativen Energiesystemen am Markt, sowie den wichtigsten Entscheidungsfaktoren zu gewähren This thesis deals with the topic of usage and subsidies of alternative energy supply systems for single-family homes. The concept of sustainability is very important in the context of this thesis. The term sustainability is therefore explained in general as well as in relation with the construction industry and private households. To meet the idea of sustainability energy production from renewable energy is indispensable. A list of all renewable sources of energy will show the corresponding advantages and disadvantages associated with energy production. In order to be able to make the right decisions with regard to the climate aspects by building a family home the activity field "Building and Living" of the Austrian Climate Change Adaptation Strategy will be explained particularly. All forms of sustainable energy generation for family homes are described in detail and compared to fossil resources. All necessary information for the acquisition, planning, installation and operation of the different systems are presented. The comparison among the alternative energy production systems is provided by considering the investment, heating and maintenance costs as well as the payback period. In context with the subsidies granted by federal government and the state of Austria a recommendation on the most favorable and efficient alternative energy system at the time of writing this thesis will be given. The market development of recent years as well as corresponding forecasts are analyzed. The aim of this thesis is to provide a good overview of the currently offered alternative energy systems on the market as well as the most important decision-making factors for the right selection. vorgelegt von: Martin Schneider Abweichender Titel laut Übersetzung der Verfasserin/des Verfassers Wien, FH Campus Wien, Masterarb., 2017

El aumento progresivo del precio de los combustibles derivados del petróleo y la contaminación del medio ambiente, debido al uso excesivo de los hidrocarburos, hace necesario utilizar energía geotérmica en la generación de eléctrica y en otros usos, como en la industria, agricultura y en la calefacción de viviendas. El recurso geotérmico es bastante considerable en el Perú y no se ha hecho uso de ella hasta la fecha. Con relación a los precios de los combustibles fósiles, se convierten en una alternativa muy competitiva y favorable para nuestro país. Su potencial aún no ha sido evaluado adecuadamente ni explorado exhaustivamente por falta de interés y la pertenencia del recurso a varios sectores. Otro punto a su favor de la energía geotérmica, es que produce mínimas emisiones contaminantes comparadas con otro tipo de tecnologías. El gran potencial geotérmico del Perú no es muy conocido, por lo que se deben hacer estudios de reconocimiento y exploración geológica estructural, geoquímica y energética especializada., The increase progressive of Price of fuels derivative of petroleum and the contamination enviroment due use excessive of hydrocarbons, make necessary utilized energy geothermic in the generation electric and other uses as industry, agriculture and heating of housing. The geothermic resources is enough considerable in the Perú and not make use them until the date with relation of the prices of fuels fossils, it convert in a alternative very competitive and favorable for our country. His potential even not been evaluated adquality, neither explorated exhaustivity by absence interest and belong resources to various sectors. Other point to his favor of the geothermic energy is that produced minimal emissions contaminated compared with other types of technologys. The great potential geothermic of Perú is not very know, by the debits make studies of recognition and exploration geologyc structural, geochemist and energytily specialize.

The baths of l'Échaillon in Saint-Jean-de-Maurienne have been known since the 16th century. They were first used for medical purposes in 1696. Many attempts were made to exploit their thermal qualities, without success. They hoped to create a hot springs resort that would equal its sisters of Tarentaise and Aix-Les-Bains. The hot mineral springs are located on a plain traversed by the Arc River, well-known for its tendency to flood. The flooding and ensuing infiltrations regularly contaminate the springs. This recurrent problem which has been known since the beginning is one of the reasons for the failure of the projects. Many analyses have confirmed the quality of the water but have not been enough to carry out the individual projects. The town gave up trying to establish a hot springs resort and kept only the baths. These were eventually replaced by a center for physical rehabilitation, which did not use the water. A study to use the springs' géothermie properties was conducted, with no follow-up. The center will soon close its doors., Les bains de l'Échaillon, à Saint-Jean-de-Maurienne, sont connus depuis le XIVe siècle. Ils seront utilisés à des fins médicales à partir de 1696. Il y aura de très nombreuses tentatives pour exploiter ces eaux thermales. Toutes échoueront. On espérait pourtant arriver à créer une station thermale qui égalerait ses consoeurs de Tarentaise et d'Aix-les-Bains. Les sources thermales sont situées dans une plaine au milieu de laquelle coule l'Arc, rivière connue pour ses débordements. Ces crues et des infiltrations contaminent les sources. Ce problème récurent et connu depuis que l 'on utilise les eaux sera une des causes d'échec des projets. Les nombreuses analyses réalisées confirmeront les qualités des eaux mais ne suffiront pas pour mener à bien les différents projets. La ville renoncera à la station thermale pour ne conserver que des bains, ceux-ci seront remplacés par un centre de rééducation fonctionnelle, qui n 'utilisera pas les eaux. Une étude pour une utilisation des propriétés géothermiques des sources sera faite mais restera sans suites. Le centre va être prochainement désaffecté., Geneletti Pierre, Aspord Jean.
