• New method for cleaning up nuclear waste

    There are more than 436 nuclear power plants operating in thirty countries, and they create a lot of nuclear waste; one of the more toxic elements in that waste is radionuclide technetium (99Tc); approximately 305 metric tons of 99Tc were generated from nuclear reactors and weapons testing from 1943 through 2010

  • Simulation of nuclear fusion shows high-gain energy output

    High-gain nuclear fusion could be achieved in a preheated cylindrical container immersed in strong magnetic fields, according to a series of computer simulations performed at Sandia National Laboratories; the method appears to be fifty times more efficient than using X-rays — a previous favorite at Sandia — to drive implosions of targeted materials to create fusion conditions

  • A long-term low carbon energy strategy is essential for a prosperous U.K.

    An urgent remodeling of the U.K. energy infrastructure is vital if the country wants to decarbonize without “the lights going out” and not be reliant on imported energy supplies, says a new report

  • Solving the major problem of renewable energy: intermittency

    Intermittency, sometimes called the Achilles’ heel of renewable energy, has so far limited the penetration of renewable sources in most power grids; engineers imagine an energy future where giant transmission grids are backed up by massive energy storage units

  • Energy from differences between salt- and fresh water – produced inland

    Production of energy from the difference between salt water and fresh water is most convenient near the oceans, but now, using an ammonium bicarbonate salt solution, researchers can combine bacterial degradation of waste water with energy extracted from the salt-water fresh-water gradient to produce power anywhere

  • Researchers develop record-breaking plastic solar cell

    Researchers at the University of California, Los Angeles (UCLA) have made a breakthrough with plastic solar cells, creating a record-breaking polymer cell that converts 10.6 percent of the sun’s energy into electricity

  • Cheaper natural gas leads to reduced U.S. carbon emissions

    In the United States, lower emission from power plants in 2009 was driven by competitive pricing of natural gas versus coal; Harvard University researchers develop a model which identifies the relationship between the cost of electricity generation from coal and gas and the fraction of electricity generated from coal

  • Future aircraft could capture, re-use some of their own power

    When an Airbus 320 lands, a combination of its weight and speed gives it around three megawatts peak available power; researchers work on making the aircraft of tomorrow contribute to their power needs by harnessing energy from the wheel rotation of their landing gear to generate electricity

  • New source of power: bugs from space

    Researchers find that bacteria normally found thirty kilometers above the earth are highly efficient generators of electricity

  • Study: No direct link between fracking, groundwater contamination

    Hydraulic fracturing (fracking) involves the high-pressure injection of water, sand and chemicals into a shale seam, which causes the rock to shatter, releasing natural gas; preliminary findings from a study on the use of hydraulic fracturing in shale gas development suggest no direct link to reports of groundwater contamination

  • Nuclear waste recycling for better nuclear power generation

    Researchers aim to produce safe nuclear fuel that can be 80 percent recycled, compared to the current 1 percent; these fourth generation nuclear power systems can lead to a reduction of the amount of high-level, long-lived nuclear waste to a tenth of what it is today, while energy output can increase hundredfold

  • Compressed natural gas as transportation fuel

    A number of different fuel sources — ethanol, biodiesel, electricity, and hydrogen — have each shown their promise as an alternative to petroleum; scientists at Argonne Lab want to add one more contender to the list of possible energy sources for light-duty cars and trucks: compressed natural gas (CNG)

  • Sea water could corrode nuclear fuel

    Japan used seawater to cool nuclear fuel at the stricken Fukushima-Daiichi nuclear plant after the tsunami in March 2011 — and that was probably the best action to take at the time; scientists have since discovered a new way in which seawater can corrode nuclear fuel, forming uranium compounds that could potentially travel long distances, either in solution or as very small particles

  • U.K. opens first marine energy park

    Energy from the waves or tides has the potential to generate up to 27 GW of power in the United Kingdom alone by 2050, equivalent to the power generated from eight coal-fired power stations

  • Mysterious flotsam in Gulf came from Deepwater Horizon rig

    Scientists track debris from damaged oil rigs, helping forecast coastal impacts in the future
