  • Battery Storage will have a Profound Impact on Smart Buildings

    Often the best ideas are the most simple and elegant. If electric vehicles and consumer devices can have battery storage why can’t buildings? And if buildings can pull electricity from the grid at off peak times and store it in batteries, wouldn’t that save money? Since 2009, Stem based in California, have been working on these questions and disrupting the energy storage industry. ...

  • Background: EU electricity and gas directives

    3.rd Energy Market Package, proposed September 2007 September 2007 the EU Commission proposed a revision of the electricity and gas market directives with amendmets of the directives on electricity and gas markets and the directives on cross-border trade of electricity and gas. The main changes are that all countries must have independant regulators of the electricity and gas markets, that these ...

  • 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 ...

  • As renewable electricity is added to the grid, are power markets misfiring?

    When increasing megawatt-hours of variable solar and wind energy began coursing through the grid, the initial concern was an operational one—could grid reliability be maintained. But it turns out those megawatt-hours are creating market challenges, as well. What needs to be done to right the markets? Travis Kavulla, vice chairman of the Montana Public Service Commission, and Albert Cheung, ...

  • US plant shutdowns, grid focus drive storage growth: Greensmith CEO

    Power plant closures and hiking transmission costs are driving up US utilities’ investment in renewable energy storage, John Jung, CEO of Greensmith, an energy storage services firm, told Wind Energy Update. Some 60 GW of US coal-fired capacity is set to close between 2012 and 2020, according to the EIA. Nuclear plant lifespans will end and the US plans $180bn in planned transmission ...

  • Fuel reduction potential of energy management for vehicular electric power systems

    In the near future a significant increase in electric power consumption in vehicles is to be expected. To limit the associated increase in fuel consumption and exhaust emissions, smart strategies for the generation, storage/retrieval, distribution and consumption of the electric power can be used. This paper considers a vehicle configuration with a conventional drive train. Two energy management ...

  • Detection and Location of Leaks in Geomembrane Liners Using an Electrical Method: Case Histories

    ABSTRACT A field-proven electrical technique, developed at Southwest Research Institute, San Antonio, Texas, is commercially available to detect and locate leaks in geomembrane liners. The electrical technique is used to inspect 100% of the geomembrane material that is covered by a conducting liquid. A voltage applied across the liner produces a uniform electrical potential distribution in ...

  • Tank terminal demonstrates the electrically operated solution for ESD Valves - case study

    Overview Since the disastrous fire at the Buncefield fuel depot in 2005, much has been done to ensure that such a catastrophic accident should not happen again. Led by COMAH (Competent Authority/Industry Standards Task Group), safeguards have been put in place by the petroleum industry to provide additional safety and environmental protection to tank storage installations. Endorsing the ...

  • Designing a sustainable hydrogen energy economy

    A general vision of a sustainable energy economy relying substantially on hydrogen produced from renewables is sketched as a potential solution to the twin global crises of climate change and depleting oil reserves. Core differences between this 'sustainable hydrogen economy' (SHE) and the original hydrogen economy (HE) proposed in the early 1970s are discussed. In transport, rather than posing a ...

  • The isoengine: realisation of a high-efficiency power cycle based on isothermal compression

    A novel high-efficiency internal combustion engine for power generation and direct-drive applications is being developed. Distillate-fuelled power plants in units of 7 MW electrical output are predicted to reach a net electrical efficiency of 60%. An efficiency of 58% is targeted for the gas-fired version. This compares with a net electrical efficiency of about 45% for advanced reciprocating ...
