ScienceDirect - Renewable and Sustainable Energy Reviews : Review on thermal energy sto... - 0 views

  • The use of a latent heat storage system using phase change materials (PCMs) is an effective way of storing thermal energy and has the advantages of high-energy storage density and the isothermal nature of the storage process. PCMs have been widely used in latent heat thermal-storage systems for heat pumps, solar engineering, and spacecraft thermal control applications. The uses of PCMs for heating and cooling applications for buildings have been investigated within the past decade. There are large numbers of PCMs that melt and solidify at a wide range of temperatures, making them attractive in a number of applications. This paper also summarizes the investigation and analysis of the available thermal energy storage systems incorporating PCMs for use in different applications.

Study: Renewable Energy Not Green | LiveScience - 0 views

  •  
    Renewable energy could wreck the environment, according to a study that examined how much land it would take to generate the renewable resources that would make a difference in the global energy system. Building enough wind farms, damming adequate number of rivers and growing sufficient biomass to produce ample kilowatts to make a difference in meeting global energy demands would involve a huge invasion of nature.

  •  
    A massive switch from coal, oil, natural gas and nuclear power plants to solar power plants could supply 69% of the US's electricity and 35% of its total energy by 2050, according to Scientific American. However, $420 billion in subsidies from 2011 to 2050 would be required to fund the infrastructure and make it cost-competitive, the publication says in "A Solar Grand Plan" presented in its January 2008 issue.

Economic viability of small to medium-sized reactors deployed in future European energy... - 2 views

  • Future plans for energy production in the European Union as well as other locations call for a high penetration of renewable technologies (20% by 2020, and higher after 2020). The remaining energy requirements will be met by fossil fuels and nuclear energy. Smaller, less-capital intensive nuclear reactors are emerging as an alternative to fossil fuel and large nuclear systems. Approximately 50 small (<300 MWe) to medium-sized (<700 MWe) reactors (SMRs) concepts are being pursued for use in electricity and cogeneration (combined heat and power) markets. However, many of the SMRs are at the early design stage and full data needed for economic analysis or market assessment is not yet available. Therefore, the purpose of this study is to develop “target cost” estimates for reactors deployed in a range of competitive market situations (electricity prices ranging from 45–150 €/MWh). Parametric analysis was used to develop a cost breakdown for reactors that can compete against future natural gas and coal (with/without carbon capture) and large nuclear systems. Sensitivity analysis was performed to understand the impacts on competitiveness from key cost variables. This study suggests that SMRs may effectively compete in future electricity markets if their capital costs are controlled, favorable financing is obtained, and reactor capacity factors match those of current light water reactors. This methodology can be extended to cogeneration markets supporting a range of process heat applications.

EIA - Press Releases - EIA Assesses Impact of Economic Growth, Oil Prices, and Future P... - 0 views

  • The U.S. Energy Information Administration (EIA) today released the complete version of the Annual Energy Outlook 2010 (AEO2010), which includes 38 sensitivity cases that show how different assumptions regarding market and policy drivers affect the Reference case projections that EIA previously released in December, 2009. In addition to considering alternative scenarios for oil prices, economic growth, and the uptake of more energy-efficient technologies, the AEO2010 includes cases that examine the impact of changes in selected policies, such as the extension of existing policies that are currently scheduled to sunset as well as the sensitivity of natural gas shale production to variations in drilling activity and the size of the resource base.

Europe To Build $46bn Renewable Energy Super Grid - 0 views

  • The renewable energy super-grid is planned to become operational in 2020 and will involve Europe's leading utilities, who will share part of the massive price tag.   The project would be the first multinational grid designed to address the fluctuating nature of green power generation, one of the main challenges slowing down the share of renewables in the baseload energy mix.   Energy from power produced from the wind farms at night could be stored in Norway's hydropower facilities to be released the following day; helping to secure a more stable energy supply.

Today's Facility Manager - Heating And Cooling Sourced From The Earth - 0 views

  • It was estimated that the geothermal system would reduce electric consumption on campus by 25% and natural gas consumption by 70%. Stiles says, “Based on an extensive monitoring study, this turned out to be quite accurate.” He notes that savings were studied very carefully for the first three years of operation, but “it is impossible to know the savings now, since the operation of the buildings has been changed so significantly. But we are confident of the persistence of savings.”

UL Environment To Test Consumer Tech Energy Efficiency Claims | EarthTechling - 1 views

  • This new certification program, according to UL Environment, will be called Energy Efficiency Certification (EEC). It will test consumer focused items, including appliances, heating, air conditioning and refrigeration systems, high tech equipment, and lighting products, against energy efficiency standards and regulations like Energy Star, Natural Resources Canada (NRCan) and California Energy Commission (CEC). Those products which are proven to meet these standards will get yet another shiny label to put on product packaging – UL Environment’s leaf encapsulating the familiar “UL” initials and including the words “Energy Verified” in black text.

Solar Planes, Trains and Automobiles | celsias° - 0 views

  • And that's not all. We reported recently on this site on the solar powered car making its way around the world. We also covered the concept of solar roads to capture usable energy. We even reported on a sail boat powered with a solar sail. Now the BBC reports   that the U.S. military has held a test run in Arizona of a UK-made solar plane, the Zephyr-6. The plane flew for more than three days, running at night on solar charged batteries. The more than 83 hour non-stop flight was the longest of any unmanned aircraft.
  •  
    Does it make sense to solar power everything? It leads to many small, and relatively expensive installations. Wouldn't it be more effective to go for a battery & plug-in concept where possible. One would loose the inflight recharging of the solar airplane, but for everything else, the plug-in concept probably provides benefits.
  •  
    In addition, the lifetime of cars, for example, is much lower than the one for solar panels. Why integrate both?
  •  
    Yes, I agree that there is too much emphasis on the novel in attempt to solve climate change. Creating technology for the designer label market to sell goods to the rich who want to tell their friends they are green. The same investment in a solid developed renewable method could yield a hundred times the reduction of carbon or more...

Chemists Break Down Pesky Greenhouse Gas (Wired.com) - 0 views

  •  
    The molecules, known as fluorocarbons, are found in plastics, clothing and refrigerants. At their heart is a union of carbon and fluorine -- a union that, thanks to their atomic configurations, is one of the strongest molecular unions known in nature. Under standard conditions, fluorocarbons are impervious to acids and bases. They don't give or receive electrons, the very currency of molecular reconfiguration. Breaking them down is possible only at temperatures approaching 2000 degrees Fahrenheit. In some situations, that stability is a blessing: Teflon is made from fluorocarbons. But so are the hydrofluorocarbon coolants in refrigerators and air conditioners -- and when released, those become greenhouse gases that can circulate for thousands of years.
