  • Energy recovery from gas compressors

    With the development of natural gas recompression plants, linked to the opening of the global gas market, which means increased exchanges and transportation between production and consumption areas, the number of energy recovery projects on this type of installation is ...

  • Case study - Oxidizer energy recovery options

    Overview The mainstream media today is full of allusions to energy awareness and conservation. Just as visible these days are media references to astronomical dollar figures that can boggle the mind. This article does not seek to break out of that mold, but rather to conform to it – as Oxidizer Stack Heat Recovery offers a tremendous opportunity for both energy conservation and ...

  • Assessing Feasibility of Direct Drive Technology for Energy Recovery from Digester Biogas

    ABSTRACTThe Regional Municipality of Waterloo completed a study, with support from Environment Canada, to evaluate the feasibility of using direct drive technology to recover energy from digester biogas. The study identified that a 150 HP engine, operating at 54 % load, could be supported by the estimated gas production of 1560 m3/d with 63 % methane by volume. ...

  • Maximum possible efficiency for energy recovery from low-grade heat sources

    Gas-to-gas heat exchangers are increasingly being used to recover low-grade heat (or cooling) to reduce energy requirements for space heating, drying and other applications. The efficiency of heat recovery is often limited by practical considerations which could – in principle – be reduced or eliminated by development of new materials and technology. However, this paper posits a fundamental ...

  • Energy recovery from waste by use of fluidised-bed technology

    Revolving type fluidised-bed technology, developed by Ebara Corp., is installed in more than 100 facilities worldwide. The technology is applied for waste, coal and in situations where a conventional fluidized bed is difficult to use. Waste and/or coal can be treated and valuable energy can be recovered from a non-renewable source. This paper describes the application of the revolving fluidised ...

  • Integrating Reverse-Electrodialysis Stacks with flow batteries for improved energy recovery from salinity gradients and energy storage

    Abstract Salinity gradient energy can be directly converted into electrical power by using reverse electrodialysis (RED) and other technologies, but reported power densities have been too low for practical applications. Herein, the RED stack performance was improved by using 2,6-dihydroxyanthraquinone and ferrocyanide as redox couples. These electrolytes were then used in a flow battery to ...

  • Nuclear power – engine for world economic recovery and development

    The benefits of nuclear energy as an economic 'growth engine' derive from the impacts of nuclear sector activity on the overall functioning of a nation's economy. To adequately assess these impacts, it is necessary to go beyond conventional monetary-based measures of growth, focusing attention on the 'real economy' in terms of successive physical investment cycles. The principles of 'real ...

  • Energy recovery potential using micro hydropower in water supply networks in the UK and Ireland

    The supply and treatment of water is a highly energy intensive process, resulting in large amounts of greenhouse gas emissions as well as incurring large economic costs. Both governments and water service providers worldwide recognise the need for more sustainable water supply systems. In recent years, the use of hydropower turbines within water supply networks has been shown as a viable option ...

  • Federal energy stimulus: The check is in the mail

    Energy efficiency companies waiting for federal stimulus money probably feel like they are being told, “The check is in the mail.” It is supposed to arrive, but when?The federal government will channel a large pot of the money through state agencies, so it is wise to keep an eye on announcements by governors and state energy offices. States must apply by May 12 for $3.1 billion in what is known ...

  • Energy efficiency: Cure for mortgage meltdown?

    By Elisa Wood October 7, 2010   My first reaction was that the Alliance to Save Energy was stretching a bit by titling its October 6 talk: “Is energy efficiency the key to recovery from the recession?” But after hearing David Goldstein’s presentation, I must admit I’m thinking about energy efficiency in a whole different way. Goldstein, author of the ...

  • Ocean Thermal Energy and Water Production

    Introduction The scarcity of potable water is a growing problem worldwide, particularly in arid regions and among developing countries. Compounding this problem is the increasing contamination of freshwater sources, which comprise only about 2.5% of all water on Earth. Of this small portion, only 0.5% of the total fresh water available is found in easily accessible sources such as ...

  • Geothermal Energy... Power from the Depths

    The Earth's crust is a bountiful source of energy—and fossil fuels are only part of the story. Heat or thermal energy is by far the more abundant resource. To put it in perspective, the thermal energy in the uppermost six miles of the Earth's crust amounts to 50,000 times the energy of all oil and gas resources in the world! The word 'geothermal' literally means 'Earth' plus 'heat.' ...

  • New energy efficiency guidance for data centres

    New guidance for data centres will incorporate new metrics covering water usage, energy recovery and the energy efficiency of operation of computing resources. The Green Grid, a global consortium of manufacturers and operators aiming to improving the energy efficiency of data centres, has launched the Data Centre Maturity Model (DCMM), a new guidance to help data centres reduce their ...

  • Mobile systems provide solar energy in northern climates

    The Department of Transportation for Alberta, Canada, is examining innovative strategies to resolve environmental issues in remote areas of the province. Portable units for harnessing solar energy have been demonstrated over the past five years as a viable method for generating the electricity needed to drive remediation systems at several sites in western Canada. The typical mobile system ...

  • Clean energy, jobs and the real estate market

    President Barack Obama wants to create five million new green jobs over the next decade. This is a big goal, but in line with what clean energy industry advocates see as possible. An upcoming international report provides some solid perspective on why green initiatives make for good job building opportunities. Scheduled for release next summer, “Greening Buildings and Communities: Costs and ...

  • Value of nuclear power in the global energy system

    With a global energy model which finds the minimum cost energy system over the time range of 1995-2055, the value of nuclear power is analysed. The model incorporates detailed descriptions of energy conversion technologies. For nuclear technologies, light water reactors and fast breeder reactors are taken into account with fuel cycle options. Major findings are: 1) the maximum introduction of ...

  • Energy efficiency: The unsung hero of our times

    As our economy continues to sputter, one little-noticed industry has been booming for a while now: energy efficiency. The sector is hiring like crazy -- a fact that speaks volumes about the close relationship between clean energy and the economic recovery that we're all waiting for. Energy efficiency could save us all. My firm works with utilities, government agencies, housing authorities, and ...

  • Are we thinking about energy all wrong?

    By Elisa Wood  April 29, 2010    The energy world operates under the premise that more is better.  If we build more power plants, we’ll have ample supply, and electricity prices will drop. Even better, if those plants are clean and ...
