• New tech taps Earth's deep heat

    Established methods for transforming Earth’s heat into electricity involve extracting hot water from rock formations several hundred feet from the Earth’s surface at the few natural hot spots around the world, then using the hot water to turn power-producing turbines; University of Minnesota researchers developed a new system — CO2-plume geothermal system, or CPG — which uses high-pressure CO2 instead of water as the underground heat-carrying fluid; the method is expected not only to produce renewable electricity far more efficiently than conventional geothermal systems, but also help reduce atmospheric carbon dioxide (CO2) — dealing a one-two punch against climate change

  • QinetiQ's OptaSense to protect India's major oil pipeline

  • Germany to scrap nuclear power by 2022

    Germany yesterday announced plans to become the first major industrialized power to shut down all its nuclear plants in the wake of the disaster in Japan; phase-out due to be wrapped up by 2022; it means that the country will have to find the 22 percent of its electricity needs currently covered by nuclear reactors from another source; Monday decision is a U-turn for Chancellor Angela Merkel, and means that the current government has adopted the timetable for a nuclear phase-out set by the previous Social Democrat-Green coalition government a decade ago; it also cancels Merkel’s decision from November 2010 to extend the lifetime of Germany’s seventeen reactors by an average of twelve years, which would have kept them open until the mid-2030s

  • Scientists: bacteria may not have consumed Deepwater Horizon methane

    A widely publicized study, published in the prestigious journal Science in January, concluded that a bacterial bloom in the Gulf of Mexico consumed the methane discharged from the Deepwater Horizon well; a new scientific paper casts doubt on that explanation, making the case that uncertainties in the hydrocarbon discharge from the blowout, oxygen depletion fueled by processes other than methane consumption, a problematic interpretation of genetic data, and shortcomings of the model used by the authors of the January study raise serious doubts about the attribution of low oxygen zones to the oxidation of methane gas; the debate has implications for the Gulf of Mexico ecosystem as well as for predictions of the effect of global warming

  • PG&E send safety information to customers living near gas pipelines

    PG&E begins notifying customers of gas transmission pipeline locations and highlights actions the company is taking to make natural gas transmission lines safer; the letter safety brochures is being to 2.5 million homeowners and businesses located within about 2,000 feet of a natural gas transmission pipeline

  • ElBaradei: nuclear still main alternative to oil

    Mohamed ElBaradei, former head of the UN International Atomic Energy Agency (IAEA) said that “Today, nuclear power is the only real alternative to fossil fuel as a source of a reliable supply”; he acknowledged that Fukushima represents a potentially significant setback for nuclear power, but said that “Chernobyl and Fukushima should be shown to be aberrations”

  • Algae could replace 17% of U.S. oil imports

    Environmental and economic security concerns have triggered interest in using algae-derived oils as an alternative to fossil fuels; growing algae, however — or any other biofuel source — can require a lot of water; researchers at the Pacific Northwest National Laboratory the far less water is required if the algae is grown in those regions in the United States that have the sunniest and most humid climates: the Gulf Coast, the Southeastern Seaboard, and the Great Lakes; water-wise algae farming could help meet congressionally mandated renewable fuel targets by replacing 17 percent of the U.S. imported oil for transportation

  • Wastewater-treatment system to produce electricity

    Scientists will bio-engineer bacteria to break down large amounts of solid waste using anaerobic digestion (without oxygen) in a reactor based on existing technology used by distilleries and pharmaceutical companies; they hope to be able to capture the gas from the process to generate electricity. Because the system would not produce other waste products, they also hope it could improve wastewater treatment in the developed world

  • Marines complete largest solar power system yet

    The U.S. Marine Corps recently completed construction of a 1.4 megawatt solar electric system at Marine Corps Base Camp Pendleton; the solar installation is currently the largest system installed to date on a Marine base; the new system is expected to generate 2,400 megawatts each year and power roughly 400 homes; it will save the base $336,000 in energy costs annually; on Monday, the Corps announced a comprehensive strategy to harness solar energy in Afghanistan to reduce fuel consumption and save lives

  • Oil industry creates center for off-shore safety

    Following several accidents on off-shore oil rigs, the U.S. oil and gas industry will launch a center dedicated to investigating safety issues related to off-shore drilling; the center will be operated by the American Petroleum Institute (API) but will be walled off from the trade group’s lobbying work

  • Growth of geothermal energy market lags behind wind and solar

    According to a recently released report, the geothermal energy market is expected to grow over the next twenty years, but will still trail far behind wind and solar; currently only twenty-six countries in the world use geothermal energy to generate power, and as of 2010 there was a total global capacity of 10,715 megawatts; in June 2010, total global capacity of wind-powered generators was 175 gigawatts; by 2020 as much as 14.4 gigawatts of new geothermal capacity will be added at a 3 percent annual growth rate; the market value is estimated to be $6.8 billion by 2020; the expansion of geothermal energy still faces several impediments; at least 350 projects currently underway face financing, drilling rig, and skilled labor shortages

  • Thorium could be answer to South Africa's energy woes

    South African scientists are increasingly touting thorium as a viable solution for the country’s energy woes; scientists believe that South Africa could use its plentiful reserves of thorium, a radioactive rare earth metal, to generate greenhouse gas-free electricity; South Africa’s aging energy infrastructure has led to rolling blackouts and energy rations; South Africa currently generates 78 percent of its energy from coal making it one of the largest contributors of greenhouse gases in the world; thorium is a better alternative to uranium in nuclear power production as it cannot be weaponized, does not need to be converted or enriched, its radioactive waste breaks down faster, and is less expensive and environmentally friendlier to extract

  • China races to claim Arctic resources

    As temperatures around the world continue to rise and the ice in the Arctic Ocean melts, the once frozen seas are increasingly open for exploration and countries have been scrambling to claim the region’s vast resources; several countries including Canada, the United States, and Russia have all sought to expand their territorial claims over the region and now new countries like China are pushing in; Chinese researchers recently sailed to within 120 nautical miles of the North Pole; only a few years prior, this trip would have been impossible due to the thick ice in the ocean that can be more than 30 feet thick; scientists estimate that during the summer months, the Arctic Ocean could be ice-free by as early as 2013 or as late as 2060
