  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • Application of temperature-distribution models to evaluate the energy and exergy of stratified thermal storages

    Vertical stratification occurs in many thermal energy storages, and is often promoted to increase efficiency. Six temperature-distribution models for vertically stratified Thermal Energy Storage (TES) systems are described and applied for determining their energy and exergy efficiencies. The models are Linear, Stepped, Continuous-linear, Basic Three-zone, General Three-zone and General-linear. ...

  • Energy Storage 301: Solar + Storage Economics - Case Study

    In this post we examine the economics of solar + storage. Specifically, we calculate the value of solar and storage for two commercial buildings in each of three markets: California, New York, and Hawaii. We find solar and storage are strongly synergistic in all three markets. The NPVs of solar + storage investments are greater than the sum of the NPVs of solar investments and storage investments ...

  • Modelling of water consumption in a spent fuel storage facility

    In current practice, spent fuel is most commonly stored in a special basin of distilled or demineralised water for a required time period to reduce the amount of heat generated by radioactive decay to a level that can permit reprocessing. The processes taking place inside the spent fuel induce complex processes in the storage basin. The loss of water from the storage basin by means of ...

  • Environmental impacts of aquifer thermal energy storage investigated by field and laboratory experiments

    Aquifer thermal energy storage (ATES) uses groundwater to store energy for heating or cooling purposes in the built environment. This paper presents field and laboratory results aiming to elucidate the effects that ATES operation may have on chemical groundwater quality. Field data from an ATES site in the south of the Netherlands show that ATES results in chemical quality perturbations due to ...

  • Control and small-signal analysis of battery and supercapacitor hybrid energy storage systems

    This paper is devoted to control strategies for an active battery and supercapacitor hybrid energy storage system using the master-slave control scheme, where the charging and discharging currents of the supercapacitor are dependent on that of battery and the current sharing ratio depends upon the load conditions. A small-signal model is proposed, which considers the variations in the currents of ...

  • Exergy analysis of a rock bed thermal storage system

    In this paper, a thermodynamic procedure is presented to analyse energy and exergy balances of a rock bed thermal storage system. The thermal behaviour is described by means of a control volume that includes three subsystems: the solar collectors, the fluid distribution system and the storage chamber. Solar-to-thermal energy conversion was obtained by means of a solar collector at a fixed airflow ...

  • The trouble with angels: carbon capture and storage hurdles and solutions

    This article examines the challenges to commercial deployment of carbon capture and storage using geologic sequestration. The authors argue that CCS will never become a reality without early federal investment in research and development, a uniform federal regulatory framework, and a framework to address the currently unknown and unquantifiable liabilities. They suggest a model similar to the ...

  • Numerical simulation of fluid flow and heat transfer in a phase change thermal energy storage

    The objective of this work is the study of an industrial process of energy storage which consists in the use of a cylindrical tank filled with encapsulated Phase Change Materials (PCM). A particularity is present in this kind of processes; it concerns the delay of the crystallisation of PCM, called supercooling phenomenon. The development of a 2D porous-medium model for cold storage with coolant ...

  • Nuclear waste storage and environmental intergenerational externalities

    This article analyses the long–term consequences of nuclear waste storage within a general equilibrium framework. The objective is to determine the conditions for which the storage of waste, and thus the transfer of externalities towards the future, can be optimal. These conditions could explain the implementation of intergenerational externalities, justifying an intertemporal Not in My Back Yard ...

  • 7 Theses on Storage Systems in Commercial Applications

    Solar storage systems are now the focus of attention more than ever before. The application areas are as different as the requirements. While private PV system operators work toward optimizing self-consumption, storage systems in industry are mainly used to provide control reserve and thus ensure grid stability. In commercial storage ...

  • Designing renewable contracts that value CSP storage

    As California ramps up its storage requirements, it has not included Concentrated Solar Power (CSP) with integrated energy storage. Instead it is testing pilot projects using batteries at utility-scale, even though it must be obvious to bean counters at utilities ...

  • Energy Security

    Renewable & Clean Energy Solutions to Secure Energy Independence from Foreign Oil. FOREIGN OIL: As imports grow and world prices rise, the amount of money we send to foreign nations every year is soaring. At current oil prices, we will send $700 billion dollars out of the country this year alone — that’s four times the annual cost of the ...

  • Capacity optimization of hydropower storage projects using particle swarm optimization algorithm

    A mixed integer optimization model is formulated for capacity optimization of a hydropower storage project with control on reliability of meeting the project's firm energy yield. Particle swarm optimization (PSO) is used as the optimization algorithm, in which the method of sequential streamflow routing is called for objective function evaluations. Two types of problems are studied. The first one ...

  • A dynamic virtual power station model comprising small-scale energy zones

    Concerns over global warming and high oil prices are expected to lead to a continuous increase in electricity generated by distributed renewable energy sources and small-scale embedded generators (SSEGs). This increase in SSEG will pose numerous technical challenges for distribution network operators. The small-scale energy zone (SSEZ) concept seeks to overcome these challenges using appropriate ...

  • Exergy analysis of a multi–tank thermal storage system for solar heating applications

    This paper presents the results of an experimental study on the stored exergy of a stratified multi–tank system when subjected to various charge and discharge strategies. Tests were performed over 8–h and 48–h test periods, for constant temperature charging, variable input power charging, constant volume hourly draws and variable volume hourly draws. For each set of test parameters, three ...
