• Sandia Labs technology used to clean up Fukushima after disaster

    A Sandia Lab-developed technology — crystalline silico-titanate, or CST — is a molecular sieve that can separate highly volatile elements from radioactive wastewater; the technology has been used to remove radioactive material from more than forty-three million gallons of contaminated wastewater at Japan’s damaged Fukushima Daiichi nuclear power plant

  • California coastal planners protect infrastructure from climate change

    California’s coastal planners and resource managers say there is a need to prepare for changes along the coast that might result from rising sea levels and other impacts, such as more floods, loss of beach access, coastal erosion, and potential damage to transportation infrastructure, including highways, roads, and ports

  • Groundwater depletion in Texas, California threatens US food security

    The U.S. food supply may be vulnerable to rapid groundwater depletion from irrigated agriculture; for example, from 2006 to 2009, farmers in the south of California’s Central Valley depleted enough groundwater to fill the U.S. largest man-made reservoir, Lake Mead near Las Vegas — a level of groundwater depletion that is unsustainable at current recharge rates

  • Removing CO2 from the flues of coal-fired power plants

    The current method of removing the greenhouse gas carbon dioxide (CO2) from the flues of coal-fired power plants uses so much energy that no one bothers to use it; scientists have developed an entirely new catalyst for separating out and capturing CO2, one that mimics a naturally occurring catalyst operating in our lungs

  • Producing renewable hydrogen

    Hydrogen is regarded as the cleanest and greenest of all fuels; a California company combines its polymer coating with a small-scale solar device to form a self-contained particle that separates hydrogen from water using only the power of the Sun

  • New geological insights to aid oil extraction, water recovery

    By understanding the variety of pore sizes and spatial patterns in strata, geologists can help achieve more production from underground oil reservoirs and water aquifers; better understanding also means more efficient use of potential underground carbon storage sites, and better evaluations of the possible movement of radionuclides in nuclear waste depositories to determine how well the waste will be isolated

  • Probability of nuclear reactor core meltdown higher than expected

    Currently, there are 440 nuclear reactors in operation, and sixty more are planned; new research finds that reactor accidents involving a core meltdown, as were the Chernobyl and Fukushima, may occur once every ten to twenty years — some 200 times more often than estimated in the past; the authors of the study note that they did not take into account potential contributing factors to accidents such as the age and type of reactors, or whether reactors are located in regions of enhanced risks such as earthquakes

  • Explaining uneven rise in sea levels

    If there is a global warming trend, one of its consequences would a rise in sea levels, which will require massive mitigation efforts to protect coastal infrastructure; rather than a uniform rise in sea level, however, the records show sea levels rising in some areas and dropping in others; Harvard researchers offer an explanation for this phenomenon

  • Solving southwest U.S. water shortage by water cap and trade?

    Lake Mead, on the Colorado River, is the largest reservoir in the United States, but users are consuming more water than flows down the river in an average year, which threatens the water supply for agriculture and households; researchers suggest that to solve this imbalance, a water cap-and-trade system, successfully implemented in Australia, should be considered for interstate water trading

  • Westinghouse, Missouri utilities promote Westinghouse Small Modular Reactor

    Westinghouse Electric Company and the Missouri Electric Alliance led by Ameren Missouri have formed a utility participation group called the NexStart SMR Alliance; alliance members signed a Memorandum of Understanding that highlights the importance of advancing nuclear energy by deploying the Westinghouse Small Modular Reactor (SMR)

  • Collecting solar power in space

    Researchers have tested equipment in space which would provide a platform for solar panels to collect the energy and allow it to be transferred back to earth through microwaves or lasers; this method would provide a reliable source of power and could allow valuable energy to be sent to remote areas in the world, providing power to disaster areas or outlying areas that are difficult to reach by traditional means

  • Groundbreaking tests to offer better understanding of post-earthquake fires

    Post-earthquake fires are a well-known and serious hazard, but very little is known about the performance of fire protection systems in earthquakes; groundbreaking tests to be conducted next week are aimed at better understanding of the effects of earthquakes on building systems designed to suppress or prevent the spread of fires

  • McAfee, Intel collaborate on protecting energy infrastructure

    McAfee and Intel will collaborate on improving the protection of the world’s energy utilities, including generation, transmission, and distribution, from increased cyber attacks; the two companies have provided a blueprint for a comprehensive solution of multiple products which create layers of security and operate together without great complexity or without impacting availability

  • Seismic safety worries about South Carolina nuclear fuel facility

    The worries about the seismic safety of nuclear energy-related facilities, worries which have only grown since the March 2011 Fukushima disaster, extend not only to nuclear power reactor, but to other facilities as well; the most recent example is a Westinghouse facility outside Columbia, South Carolina, one of only three facilities in the United States which make nuclear fuel for commercial reactors

  • Groundwater pumping causes sea level rise, canceling out effect of dams

    Those in charge of infrastructure protection must now worry about another source of sea level rise: water pumped out of the ground for irrigation, drinking water, and industrial use; this water ends up emptying into the world’s oceans, and scientists calculate that by 2050, groundwater pumping will cause a global sea level rise of about 0.8 millimeters per year
