  • The Potential for Geologic Hydrogen for Next-Generation Energy

    Hydrogen, you may recall from your school days, is a gas. It is considered the cleanest fuel, because burning it only produces heat and pure water. A previously overlooked, potential geologic source of energy could increase the renewability and lower the carbon footprint of the U.S. energy portfolio: natural hydrogen.

  • Shutting Down Nuclear Power Could Increase Air Pollution

    Nearly 20 percent of today’s electricity in the United States comes from nuclear power. If reactors are retired, polluting energy sources that fill the gap could cause more than 5,000 premature deaths, researchers estimate.

  • From High to Low in 15 Years: Coal Continues Its Precipitous Decline

    The country’s power generators used more coal in 2007 than ever before — a little over one billion tons. This year, coal use by U.S. electric-power producers would likely not reach 400 million tons. Roughly 40 percent of the country’s current coal-fired capacity is set to close by 2030. “This is not an economic cycle that is simply going to go away,” says an expert. “It is a real phaseout across the industry of the use of coal.”

  • Polish Shale Gas May Be the answer to the EU's Energy Shortage

    Although there is currently no shale gas production in Europe, Polish energy experts say it could easily be brought back to the table to alleviate the European energy crisis.

  • Kites Aim to Tap Unused High-Altitude Wind Power

    There is a growing interest in harvesting what are known as high-altitude winds. At a height of 200 meters (656 feet) and more, winds tend to blow stronger and more steadily than those closer to the ground. High-altitude winds remain a huge untapped source of renewable energy, but a race to the sky is well underway.

  • If the Price Is Right: Fusion's Future in the U.S. Could Come Down to Dollars and Cents

    Fusion energy is often hailed as a limitless source of clean energy, but new research suggests that may only be true if the price is right. The researchers say that the engineering challenges of fusion energy are only part of the problem — the other part lies in economics.

  • Solar Thermal Tower Key Component of National Energy Goals

    Sandia hosted a Feb. 16 groundbreaking ceremony to begin the construction of a new solar tower at the National Solar Thermal Test Facility. The project is part of DOE’s effort to develop concentrating solar power technology that may provide clean, utility-scale electricity.

  • Tidal Stream Power Can Significantly Enhance Energy Security

    A new study reveals the potential of tidal resources to make a marked difference on a community’s clean energy ambitions. Using tidal technologies as part of a renewable energy mix can also reduce the space required for power-generating facilities, both on land and at sea, by around 33% and significantly reduce their visual impact since much of their operation is below the sea’s surface.

  • Illuminating the Barrier to Next-Generation Battery That Charges Very Quickly

    In the race for fast-charging, energy-dense lithium metal batteries, researchers discovered why the promising solid electrolyte version has not performed as hoped. This could help new designs – and eventually battery production – avoid the problem.

  • Interest in Geothermal Energy is Growing

    These days, some 400 power plants in 30 countries generate electricity using steam generated beneath the earth’s surface, producing a total capacity of 16 gigawatts (GW). Despite its advantages, geothermal energy has seen limited use compared to fossil fuels, but recent energy shocks have increased interest in this energy source.

  • Can Floating Solar Islands Meet the World’s Future Energy Needs?

    Covering less than ten per cent of the world’s hydropower reservoirs with floating solar panels would yield as much energy as all hydropower does today, one researcher says.

  • Space Solar Power Technology Demo Launched into Orbit in January

    Space solar power provides a way to tap into the practically unlimited supply of solar energy in outer space, where the energy is constantly available without being subjected to the cycles of day and night, seasons, and cloud cover.

  • Europe Faces a Chilling Couple of Years, but Russia Will Lose the Energy Showdown

    In the European Union this winter, fears of rolling blackouts triggered by Russian energy export cuts amid Moscow’s war in Ukraine have subsided thanks to good luck, good weather, and quick action. “In the long run, Russia simply can’t win this energy war,” says an expert.
