  • Nature Energy article: ‘Open discussion of negative emissions is urgently needed’

    At the moment, nearly all model-based scenarios that limit global warming to 2 °C or less use negative CO2 emission technologies (NETs), particularly bio-energy with carbon capture and storage (BECCS). Still, investments in these technologies continue to be relatively small, and concerns are being raised regarding the large-scale application of such technologies. If no explicit policy ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Prioritising sources of risk at liquefied natural gas storage terminals in Mexico

    Liquefied natural gas (LNG) operations and facilities are growing in scale and number in developed and developing countries. The associated hazards to human health and safety and the environment are being addressed systematically. This paper discusses and refines existing methods to perform identification, screening, and prioritisation for a variety of sources of risk in LNG processes. The steps ...

  • 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 ...

  • 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 ...

  • Building Energy Modeling 101: HVAC Design and Operation Use Case

    A great deal of energy use in buildings goes toward heating, ventilation, and air-conditioning (HVAC). In 2015, HVAC consumed 15.5 quads. The first step in reducing HVAC energy use is reducing heating and cooling load—i.e., the amount of heat that needs to be added to or removed from a building—typically by reducing heat from equipment and lighting; minimizing unnecessary ...

  • A comercial store for the solar energy

    In this paper we will introduce our mathematical model for the solar energy sink, which can be used in general for the bio-energy processing. This model was based on the basic principle property of the heat capacity for the working mixture of the reservoir. Our modification here was to convert the storage energy into an energized air rotating any turbine, and generator to power electricity for ...

  • The Energy Revolution is Here

    We live in an exciting time. Yes, glaciers are melting, sea levels are rising, and in my new home in the Western United States, earlier snowmelts, longer summers, and hotter temperatures have made wildfires 400 percent more frequent. And yet, there are encouraging signs we are in the midst of an energy revolution that is sure to transform our climate, our economy, and our lives for the better. ...
