    The new battery relies on an innovative architecture called a semi-solid flow cell, in which solid particles are suspended in a carrier liquid and pumped through the system. In this design, the battery's active components - the positive and negative electrodes, or cathodes and anodes - are composed of particles suspended in a liquid electrolyte. These two different suspensions are pumped through systems separated by a filter, such as a thin porous membrane.

    If a report released Tuesday by the International Energy Agency is correct, then the $2 billion committed by the Alberta government toward the development of carbon capture and storage is nothing more than a drop in the bucket. The IEA estimates it will cost as much as $10 trillion U.S. between 2010 and 2030 for the world to keep carbon dioxide emissions below 450 parts per million and temperatures from rising more than 3.6 degrees Fahrenheit. While that level of investment might be enough for even the most ardent climate change advocate to throw their hands up and surrender, there's a little bit of good news to be found in the report.

    Carbon capture and storage (CCS) are possible, but the cost of doing so - both early on and even as the technology matures - is likely to be staggering, according to a study from Harvard University's Belfer Centre for Science and International Affairs.

    "Shell, on behalf of the Athabasca Oil Sands Project, a joint venture among Shell Canada (60 per cent), Chevron Canada Limited (20 per cent) and Marathon Oil Sands L.P. (20 per cent) has proposed a carbon capture and storage (CCS) project. The Quest CCS Project would be based at Shell's Scotford Upgrader, located near Fort Saskatchewan, Alberta. Commissioned in 2003, the Upgrader turns bitumen from the Athabasca oil sands into synthetic crude oil, most of which is turned into consumer products such as gasoline."

  • Light and compact lithium-ion batteries sound great for electric vehicles--aside from their historical tendency to catch fire. But recent advances in electrode chemistry have made them much safer. One of the first vehicles to use the new batteries comes from a Norwegian company, Think. By year's end, Think plans to start selling ultracompact electric cars with a range of more than 100 miles. A123 Systems of Watertown, MA, and Indianapolis's EnerDel will provide the batteries.

  • Most experts agree that prices for energy storage will fall in coming years, but disagree over how far and how quickly. This is an important debate because a significant drop in battery prices could have wide-ranging effects across industries and society itself. In particular, cheaper batteries could enable the broader adoption of electrified vehicles, potentially disrupting the transportation, power, and petroleum sectors.

    This article suggests that 10Gb ethernet (copper) is about to take over the (optical) fibre channel for storage area networks. Caution: these networks are usually physically small and dense so cable lengths are short. The added value is high enough to justify the costs (Cost per switsch port still ~100 times higher than 1Gb, tricky cable installation).The comments at the end of the article that imply that 10Gb will be common are unconvincing.

  • Xtreme Energetics has investigated the possibility of using mechanical trackers to perform the same light-focusing duties as other solar array manufacturers have. However, HP’s transparent transistor can do the job electronically, rather than mechanically, and significantly reduce the costs of such an installation. Such a solar array is known as a concentrating photovoltaic (or CPV) solar array. To date, CPV arrays are fairly expensive and cannot store energy, making them less useful. They also work best in specific sections of the world — those with the highest levels of solar radiation, such as the southwest United States and northern Africa.

  • Once construction of its innovative plant in Stephentown, New York, is complete, Beacon Power expects to be able to provide up to 20 megawatts of energy capacity to the region’s electricity grid. The first four megawatts of capacity are set to come online earlier, however — by the end of this year.

  • In the latest Electric Power Research Institute Journal, an article titled "Hydropower Reservoirs: A Question of Emissions" notes that reservoirs used for hydropower and for pumped-hydro energy storage are not necessarily as green as you might imagine. Or rather, they might be too green: carbon-rich organic material that accumulates on the reservoir floor can be the source of carbon emissions. A recent study of the 90-year-old Lake Wohlen, in Switzerland, for example, found high emissions of methane, as recently reported in the journal Environmental Science and Technology, in an article titled: "Extreme Methane Emissions from a Swiss Hydropower Reservoir: Contribution from Bubbling Sediments."

    Applies to both hydro reservoirs (i.e. water pooled behind a dam) and hydro pools filled with pumped-hydro. Note that the latter, pumped-hydro, already carries the emissions profile of the energy used to power the turbine pumping the water against gravity, scaled up for conversion efficiency losses.
