Geothermal energy is a renewable and clean source that has been used for electricity generation in some countries since the 50s, the main characteristic to be used in this application is that the subsoil must have a high temperature geothermal resource (+150 °C). However, it can also be used in applications such as air conditioning in places where the temperature is around 30°C; In Europe alone, there are more than one million thermal installations operating by harnessing geothermal energy. The objective of the work was to design a cooling system from the storage of underground energy, for that, it is essential to know the variation of subsoil temperatures during a certain period of time. For this purpose, sensors were used that were installed at different depths and by means of an Arduino, information of a whole year was stored; so that these data are as representative as possible of the energy storage conditions and the changes depending on the seasons that pass. Additionally, the characteristics of the soil (conductivity, humidity and composition) were taken into account, where the equipment is intended to be installed in subsequent works. For the determination of the necessary cooling load, the design requirements of the ASHRAE standard were used and for the design of the underground heat exchanger, references of designs recommended through experimental tests in other research works are included, together with internal fluid methodology and one-dimensional heat transfer. It includes elements that can help improve the dissipation of energy into the subsurface and maintain transfer properties as stable as possible. This design is designed for the air conditioning of a classroom of normal dimensions that are used in the University and therefore avoid the energy consumption of conventional air conditioning equipment.

The requirement for energy is increasing worldwide as populations and economies develop. Reasons for this increase include global warming, climate change, an increase in electricity demand, and paucity of fossil fuels. Therefore, research in renewable energy technology has become a central topic in recent studies. In this study, a solar-assisted house heating system with a seasonal underground thermal energy storage tank is proposed based on the reference system to calculate the insulation thickness effect, the collector area, and an underground storage tank volume on the system performance according to real weather conditions at Jeju Island, South Korea. For this purpose, a mathematical model was established to calculate its operating performance. This mathematical model used the thermal response factor method to calculate the heat load and heat loss of the seasonal underground thermal energy storage tank. The results revealed that on days with different weather conditions, namely, clear weather, intermittent clouds sky, and overcast sky, the obtained solar fraction was 45.8%, 17.26%, and 0%, respectively. Using this method, we can save energy, space, and cost. This can then be applied to the solar-assisted house heating system in South Korea using the seasonal underground thermal energy storage tank.

Due to the extensive utilization of liquid nature gas (abbreviated as LNG) resources and a multitude of considerations, LNG storage tanks are gradually transitioning towards smaller footprints and heightened safety standards. Consequently, underground LNG storage tanks are being designed and constructed. However, underground LNG storage tanks release a considerable quantity of cold into the ground under both accidental and normal conditions. The influence of cold results in the ground freezing, which further compromises the safety of the structure. Existing research has neglected to consider the effects of this. This oversight could potentially lead to serious safety accidents. In this work, a complete set of experiments using a novel LNG underground storage tank fluid-solid-thermal coupled cryogenic leakage scale model were conducted for the first time to simulate the effect of the tank on the soil temperature field, stress field, and displacement field and to analyze the development of the three fields and the results of the effect. This research helps the related personnel to better design, construct, and evaluate the LNG underground storage tanks to avoid the catastrophic engineering risks associated with cryogenic leakage and helps to improve the design process of LNG underground storage tanks.

ABSTRACT This paper discusses the limitations imposed on internal volumetric leak detection systems for underground gasoline storage tanks by uncertainty in the value of the thermal expansion coefficient for gasoline and uncertainties in measurements of the temperature of the gasoline. For leak detection or level sensing systems that are used to infer or measure volumetric leak rates, correction must be made to account for the expansion or contraction of the gasoline. An analysis is made of experimental determinations, in other work, of the density of samples of gasoline and calculated values of the thermal expansion coefficient. The data are divided according to three categories of gasoline: regular, unleaded, and premium. In each of these categories the estimate of the standard deviation of the thermal expansion coefficient is approximately 3 percent of the mean value. Examples are given of the magnitude of the apparent leak rate or error in leak rate due to uncertainties in the thermal expansion coefficient. In order to correct for expansion or contraction of the gasoline, the mean temperature of the entire quantity of the gasoline must be known. An error in mean temperature will result in an apparent leak rate or an error in leak rate. Examples are given of the magnitude of the apparent leak rate or error in leak rate.

This study deals with mathematical modeling and energy analysis of an ice rink cooling system with an underground thermal energy storage tank. The cooling system consists of an ice rink, chiller unit, and spherical thermal energy storage tank. An analytical model is developed for finding thermal performance of the cooling system. The model is based on formulations for transient heat transfer problem outside the thermal energy storage tank, for the energy needs of chiller unit, and for the ice rink. The solution of the thermal energy storage tank problem is obtained using a similarity transformation and Duhamel superposition techniques. Analytical expressions for heat gain of the ice rink and energy consumption of the chiller unit are derived as a function of inside design air, ambient air, and thermal energy storage tank temperatures. An interactive computer program in Matlab based on the analytical model is prepared for finding hourly variation of water temperature in the thermal energy storage tank, coefficient of performance of the chiller, suitable storage tank volume depending on ice rink area, and timespan required to attain an annually periodic operating condition. Results indicate that operation time of span 6–7 years will be obtained periodically for the system during 10 years operating time.

Geothermal energy storage provides opportunities to store renewable energy underground during summer for utilization in winter. Vertically oriented systems have been the standard when employing boreholes as the means to charge and discharge the underground. Horizontally oriented borehole storage systems provide an application range with specific advantages over vertically oriented systems. They are not limited to the surface requirements needed for installation with vertical systems and have the potential to limit storage losses. Horizontal systems can be incorporated into the built environment and utilize underground storage sites below existing infrastructure. An experimental study examines configurations using a mix of renewable energy (photovoltaic panels) and grid energy to charge a storage system during summer for use during winter. A comparison of five different borehole configurations at three different loading temperatures was composed using an experimentally validated numerical model. The horizontal systems studied and analyzed in this work showed improved performance with scale and charging temperature. This paper supports further exploration into specific use cases for horizontal borehole thermal energy storage systems and suggests applications which would take advantage of better performance at scale.

Underground Thermal Energy Storage (UTES) systems are energy conservation systems used to buffer the difference between energy supply and energy demand and therefore represent an interesting alternative to energy depletion. At the same time they contribute to cut CO2 emissions by a reduction of energy demand from traditional heating/cooling systems. Even though UTES are relatively environmental friendly solutions they are not completely free of impacts on the underground. They have possible hydro(geo)logical, chemical, thermal or microbiological impacts that are obviously strongly interrelated. The risks of UTES to groundwater quality are insufficiently known, and policies to address this uncertainty are still lacking. In order to improve the understanding and knowledge of UTES techniques, this study aimed to perform a Life Cycle Analysis (LCA) on two different UTES systems: Aquifer Thermal Energy Storage (ATES) and Borehole Thermal Energy Storage (BTES). Even if at present LCA has been mainly performed on products of the industrial and building sector it can be a useful instrument to determine the sustainability of these two possible alternatives of underground exploitation.

The United States Department of Energy indicates that 97% of all homes in the US use fossil fuels either directly or indirectly for space heating. In 2005, space heating in residential homes was responsible for releasing approximately 502 million metric tons of carbon dioxide into the atmosphere. Meanwhile, the Sun provides the Earth with 1000 watts per square meter of power everyday. This document discusses the research of modeling a system that will capture and store solar energy during the summer for use during the following winter. Specifically, flat plate solar thermal collectors attached to the roof of a single family home will collect solar thermal energy. The thermal energy will then be stored in an underground fabricated Seasonal Solar Thermal Energy Storage (SSTES) bed. The SSTES bed will allow for the collected energy to supplement or replace fossil fuel supplied space heat in typical single family homes in Richmond, Virginia. TRNSYS is a thermal energy modeling software package that was used to model and simulate the winter thermal load of a typical Richmond home. The simulated heating load was found to be comparable to reported loads for various home designs. TRNSYS was then used to simulate the energy gain from solar thermal collectors and stored in an underground, insulated, vapor proof SSTES bed filled with sand. Combining the simulation of the winter heat demand of typical homes and the SSTES system showed reductions in fossil fuel supplied space heating in excess of 64%.

Coupling effects between thermal, hydraulic, chemical and mechanical (THCM) processes for rock materials are one of major issues in Geological engineering, Civil engineering, Hydrology, Petroleum engineering, and Environmental engineering. In all of these fields, at least two mechanisms of THCM coupling are considered. For an example, thermal, hydraulic, and mechanical coupling effects are important in Geological engineering and Civil engineering. The THM coupling produces effects on underground structures, since the underground structures are under influences of geothermal gradient, groundwater, gravitational stresses, and tectonic forces. In particular, underground repository of high-level nuclear waste involves all four of the THCM coupling processes. Thermo-hydro-mechanical coupling model for fractured rock media has been developed based on micromechanical fracture model [Kemeny 1991, Kemeny & Cook 1987]. The THM coupling model is able to simulate time- and rate-dependent fracture propagation on rock materials, and quantify characteristics of damage by extensile and shear fracture growth. The THM coupling model can also simulate coupled thermal effects on underground structures such as high-level nuclear waste repository. The results of thermo-mechanical coupling model are used in conducting a risk analysis on the structures. In addition, the THM coupling model is able to investigate variations of fluid flow and hydraulic characteristics on rock materials by measuring coupled anisotropic permeability. Later, effects of chemical coupling on rock materials are investigated and modified in the THM coupling model in order to develop a thermo-hydro-chemo-mechanical coupling model on fractured rocks. The THCM coupling model is compared with thermal, hydraulic, chemical, and mechanical coupling tests conducted at the University of Arizona. The comparison provides a reasonable prediction for the THCM coupling tests on various rock materials. Finally, the THCM coupling model for fractured rocks simulates the underground nuclear waste storage in Yucca Mountain, Nevada, and conducted performance and risk analysis on the repository.

The current environmental challenges that face the world put pressure on the heating market to move towards increased share of renewable energy sources as fuel. District heating (DH) is seen as an efficient solution to achieve this in dense urban areas. Thermal energy storage (TES) is seen as a solution to handle the increased amount of intermittent energy sources in the energy system. For the Swedish DH business a large-scale underground TES (UTES) is seen as an interesting solution partly for this reason and partly to utilise more residual heat and heat from under-utilised production facilities. However, the current complexity to invest in large-scale UTES is limiting the further development of DH. The purpose of this report is therefore to fill the current knowledge gap regarding factors needed to analyse an investment in large-scale UTES. An investment framework is presented to be used as decision support mainly for decision-makers in the DH business, but which can be interesting for other stakeholders in the district heating system (DHS). The main findings of the report are that there exists necessary circumstances for an investment in a large-scale UTES and that the criteria needed to evaluate an investment in large-scale UTES are either related to economy or environment. Further, the main function of a large-scale UTES is seasonal storage because this function creates the majority of the revenue. This revenue is created through storage of cheap heat during periods of low heat demand, which replaces expensive peak production during periods of high heat demand. Depending on the size of the created revenue, the large-scale UTES can be profitable as required by the DH companies. However, it is shown in the report that other factors also must be considered for the large-scale UTES to become profitable. Further, the uncertain future of DH poses a challenge for the evaluation of an investment in large-scale TES. The recommendations for further studies therefore focus on limiting these uncertainties through additional research and development.
De nuvarande miljöförändringar som världen står inför ställer krav på värmemarknaden att förändras till ökad användning av förnybara energikällor som bränsle. Fjärrvärme ses som en effektiv lösning för att åstadkomma detta i tätbebyggelse. Termiska energilager (TES) ses som en lösning för att hantera den ökande mängden intermittenta energikällor i energisystemet. För den svenska fjärrvärmen ses ett storskaligt underjordiskt TES (UTES) som en intressant lösning dels av denna anledning dels för att öka användningen av restvärme och värmen från underutnyttjade produktionsanläggningar. Hursomhelst så innebär den nuvarande komplexiteten att investera i storskalig UTES att utvecklingen för fjärrvärme begränsas. Syftet med denna rapport är därför att fylla den kunskapslucka som existerar gällande faktorer att analysera för en investering i ett storskaligt UTES. Ett investeringsramverk presenteras för att användas som beslutsunderlag för huvudsakligen beslutsfattare inom fjärrvärmeverksamheten, men som även kan vara av intresse för andra intressenter i fjärrvärmesystemet. De huvudsakliga upptäckterna från denna rapport är att det existerar nödvändiga förutsättningar för en investering i storskalig UTES och att kriterierna för utvärdering av en investering i storskalig UTES antingen är relaterade till ekonomi eller miljö. Vidare så är den huvudsakliga funktionen av ett storskaligt UTES säsongslagring eftersom denna funktion skapar lejonparten av inkomsten. Inkomsten skapas genom lagring av billig värme under perioder av låg efterfrågan på värme som ersätter dyr spetsproduktion under perioder av hög efterfrågan på värme. Beroende på storleken av den skapade inkomsten så kan ett storskaligt UTES potentiellt klara kravet på att vara lönsamt. Hursomhelst så visar denna rapport på att andra faktorer troligen också behöver tas hänsyn till för att ett storskaligt UTES ska bli lönsamt. Trots att det är nödvändigt så gör den osäkra framtiden för fjärrvärme det svårt att utvärdera en investering i storskalig UTES. Rekommendationerna för framtida studier fokuserar därför på att begränsa dessa osäkerheter genom ytterligare vetenskapligt stöd.

La réduction des émissions de gaz à effet de serre provenant des énergies fossiles combinée à l'augmentation de la demande mondiale en énergie représente un défi majeur pour l'humanité. Nous ne pourrons le résoudre sans un recours massif aux énergies renouvelables. L'énergie solaire est l'une des formes renouvelables les plus abondantes et disponibles. Diverses techniques sont utilisées pour exploiter cette énergie, telles que les panneaux solaires photovoltaïques pour la production d'électricité et les capteurs solaires thermiques pour la production de chaleur. Récemment, une autre approche a émergé, celle des routes solaires, offrant à la fois des infrastructures de transport et des capacités de captation d'énergie solaire. Dans ce contexte, cette thèse propose l'étude et le développement d'un système couplant énergétiquement une chaussée à un bâtiment via un stockage thermique. Le concept repose sur la récupération de chaleur de la chaussée pendant les périodes chaudes, via un fluide caloporteur circulant dans un revêtement de chaussée drainant placé sous la couche de roulement. Cette chaleur est ensuite stockée au sein d'un stockage thermique composé de sable saturé en eau en sous-sol du bâtiment afin d'être mobilisée ultérieurement. Le chauffage et la production d'eau chaude sanitaire mettent en œuvre une pompe à chaleur. Un modèle thermique et énergétique a été développé pour l'ensemble du système. Les prédictions du modèle sont comparées aux résultats expérimentaux obtenus à l'aide d'un démonstrateur spécifiquement développé pour les besoins de l'étude. Les simulations annuelles montrent qu'il est possible de chauffer efficacement des maisons individuelles ou des petits collectifs répondants aux réglementations énergétiques actuelles en valorisant l'énergie thermique des routes avec un coefficient de performance moyen de la pompe à chaleur voisin de 6.5. Une étude de sensibilité du système a montré que la superficie du capteur, le volume du stockage et le lieu d'implantation ont une influence sur les performances du système
Reducing greenhouse gas emissions from fossil fuels combined with increasing global energy demand represents a major challenge for humanity. We will not be able to solve it without massive recourse to renewable energies. Solar energy is one of the most abundant and available forms of renewable energy. Various techniques are used to harness this energy, such as photovoltaic solar panels for electricity production and solar thermal collectors for heat production. Recently, another approach has emerged, that of asphalt solar collector, offering both transport infrastructure and solar energy capture capacities. In this context, this thesis proposes the study and development of a system energetically coupling a roadway to a building via thermal storage. The concept is based on recovering heat from the roadway during hot periods, via a heat transfer fluid circulating in a draining road surface placed under the wearing course. This heat is then stored in a thermal storage composed of sand saturated with water in the basement of the building in order to be mobilized later. Heating and domestic hot water production use a heat pump. A thermal and energy model has been developed for the entire system. The model predictions are compared to experimental results obtained using a demonstrator specifically developed for the needs of the study. Annual simulations show that it is possible to efficiently heat individual houses or small collectives meeting current energy regulations by using the thermal energy of the roads with an average coefficient of performance of the heat pump close to 6.5. A sensitivity study of the system showed that the surface area of the sensor, the storage volume and the location have an influence on the performance of the system

A summary of the ongoing conversion from fossil fuel energy economy to sustainable energy is offered. A large fraction of the energy-related work force in the US has shifted to renewables, typified by the high demand for wind turbine technicians. A plan for full conversion to sustainable energy has been offered by Jacobson and collaborators, depending upon increased energy storage using underground thermal storage (UTES), thermal salt application in solar thermal installations, and pumped hydro. Hothouse earth events, extinguishing nearly all life, in climatic history are mentioned. The chance for triggering a future global hyperthermal event appears to be small from the excess carbon emissions of the past two centuries, with the present rate of emission.

Abstract Concentrated Solar Power (CSP) is one of the most promising ways to generate electricity from solar thermal sources. In this situation, large tracking mirrors focus sunlight on a receiver and provide energy input to a heat engine. Inside the receiver the temperature can be well above 1000°C, and molten salts or oils are typically used as heat transfer fluid (HTF). However, since the sun does not shine at night, a remaining concern is how to store thermal energy to avoid the use of fossil fuels to provide baseline electricity demand, especially in the late evenings when electricity demand peaks. In this study, a new method will be investigated to store thermal energy underground using a borehole energy storage system. Numerical simulations are undertaken to assess the suitability and design constraints of such systems using both molten salt as HTF.

ABSTRACT: We present a laboratory setup to test the energy budget of underground heat storage in an otherwise impermeable rock through engineered fractures, a so-called Fracture Thermal Energy Storage (FTES) system. A hydraulic fracture is first created in a cubic specimen of Zimbabwe Gabbro. In the experiment, de-ionized water is circulated under high pressure through an injection steel tubing automatically heated to a target temperature. The fluid adjusts to the tubing temperature during its flow before entering a production well drilled into the 250 mm edge length block. The warm fluid then circulates through the previously created hydraulic fracture at mid-height of the block toward a production well drilled at the block periphery. The production well is equipped with a dedicated completion to allow fluid outflow. External fracture appearances are sealed using an epoxy resin. We demonstrated through the results of a preliminary heating experiment that we can transfer nearly all of the heat from the circulating fluid to the block. An efficient charging of the thermal battery is achieved. This first experiment is currently under further improvement and will ultimately help to better understand the engineering of mid- to large-scale field implementation of FTES systems. 1 INTRODUCTION Storing excess heat produced during summer or as a byproduct of industrial treatments is of widespread interest in the context of the energy transition. Typically, the peaks in energy production are not aligned with peak consumption. This mismatch is notably observed for inter-seasonal differences in demand and production. Underground thermal energy storage (UTES) systems could provide an efficient mechanism to overcome these limitations. Several types of UTES systems are being used as of today. The most used systems, not including any phase change of the temperature carrier, as of today are Aquifer Thermal Energy Storages (ATES) (Bloemendal et al., 2015). Other systems include the use of a series of boreholes (Borehole Thermal Energy Storage - BTES) or underground caverns (Cavern Thermal Energy Storage - CTES). All of these systems have regulatory, economic, and geological advantages and disadvantages.

ABSTRACT The current energy storage wave that looks at low temperature and heat storage in shallow reservoirs as well as the intensification of Hydrogen storage (especially as by product to methane) have reopened the quest for accurate and precise well temperature prediction and modeling. This prediction plays a critical role in the determination of wellbore storage capabilities, well integrity and overall energy storage efficiency. This paper shows experimental results on measuring thermal properties of various cement properties as well as selected rock which are used as comparison. Our data will show that small amount of additive products in cement may dramatically change cement thermal properties that could become important for the overall well heat transfer and thus will enhance the energy storage efficiency. INTRODUCTION With the focus of the world going toward the net zero goal with respect to carbon emission, the storage of hydrogen in the subsurface will play an important role to achieve that target. It is reported by Tarowskia and Uliasz-Misiak, (2022) that due to the ease of hydrogen availability around the world and increasing global acceptance, hydrogen has the potential to replace fossil fuel by 2050. At the moment the main source of hydrogen storage at the surface consists of the cryogenic and high-pressure tank. However, with further expansion of hydrogen gas as a source of renewable energy the storage capacity has to be increased. In this respect, underground hydrogen storage (UHS) gives an alternate solution in which hydrogen is injected into a suitable geological formation such as a depleted oil and gas reservoir, aquafer, and salt cavern, and can be reproduced when needed (Sambo, et al., 2022). As the only connection to the UHS is the well so it is of utmost importance that the integrity of the well is maintained. Hence, well cement plays an important role in the well integrity as it provides zonal isolation, give support to the casing, and seals of the problem some subsurface formation (Rincon, et al., 2022). Like any other subsurface gas storage, well cement will be exposed to different temperature cycles due to the process of injection and reproduction that can lead to thermal loading and degradation of the cement matrix. Therefore, it is necessary to know the thermal properties of the cement placed in the UHS so that the integrity of the well can be assured.

The DoD considers improving Arctic capabilities critical (DoD 2019; HQDA 2021). Deployment of shallow geothermal energy systems at cold regions installations provides opportunity to increase thermal energy resilience by lessening dependence on fuel supply and supporting installations’ NetZero transitions. Deployment can be leveraged across facilities, for ex-ample using Fort Wainwright metrics for implementation of geothermal in cold region bases. Fort Wainwright is an extreme case of heating dominant loads owing to harsh conditions in Alaska, making it ideal for proving feasibility in most heating dominant installations. Proven feasibility and potential mass deployment will help reduce emissions and increase resilience across the DoD cold region network. This report introduces the shallow geothermal energy and storage technology combination that would best fit demonstration in Alaska. Focus is on leveraging shallow, low-temperature geothermal for the development of a larger geothermal district heating and cooling (GDHC) system with underground thermal energy storage (UTES) and geothermal heat exchangers (GHX). Such systems are proven in cooling dominant climates, and individual components are proven in heating dominant climates, but deployment of a larger system in a heating dominant climate is not well established. Deployment at Fort Wainwright would represent an improvement in the technology.
