• Fracking generates less wastewater per unit of gas, but more overall

    Hydraulically fractured natural gas wells are producing less wastewater per unit of gas recovered than conventional wells would. The scale of fracking operations in the Marcellus shale region – which stretches from New York to Virginia and accounts for about 10 percent of all natural gas produced in the United States today — is so vast, however, that the wastewater it produces threatens to overwhelm the region’s wastewater disposal capacity.

  • The untapped potential of tidal power

    New research from a global group of scientists and engineers has been published in a special issue journal of the Royal Society. The work is in support of tidal power, which has the potential to provide more than 20 per cent of the U.K. electricity demand. While the predictable nature of tides makes them an ideal renewable energy source, more so than wind, the ability effectively to harness energy from the tides has so far proved elusive.

  • New York State power plants showing their age

    New York State could face power plant closings in the near future as a result of updated environmental regulations and the fact that plants in the state are outdated and inefficient; a recent report concluded that New York’s coal and nuclear power plants, as well as steam and turbine plants that run on oil or gas, are on average older than others around the country

  • Innovative Atmospheric Vortex Engine for energy generation

    See video

    A Canadian company offers a new energy generation concept: the Atmospheric Vortex Engine (AVE) uses low-temperature waste heat to create a tornado-like atmospheric vortex; in contrast with a real tornado, the vortex cannot go anywhere because it is anchored to its heat source. So it is really more like a dust devil or waterspout, and it serves as a low-cost virtual chimney

  • Fuels, household chemicals made from sugar

    Scientists at the University of Manchester have identified a biocatalyst which could produce chemicals found in ice-cream and household items such as soap and shampoo — possibly leading to the long-term replacement of chemicals derived from fossil fuels

  • Wind and solar power, paired with storage, would be cost-effective way to power grid

    Renewable energy could fully power a large electric grid 99.9 percent of the time by 2030 at costs comparable to today’s electricity expenses, new research says; a well-designed combination of wind power, solar power, and storage in batteries and fuel cells would nearly always exceed electricity demands while keeping costs low, the study authors found

  • Marines looking for solar energy in combat outposts

    The Office of Naval Research (ONR) is looking to the sun for energy in an effort to help Marines do away with diesel-guzzling generators now used in combat outposts; the Renewable Sustainable Expeditionary Power (RSEP) program seeks to create a transportable renewable hybrid system that can provide Marines with electricity for a 15-day mission without relying on fuel resupply convoys that often become targets for adversaries

  • Responding to future oil spills: lessons learned from Deepwater Horizon

    A special collection of articles about the Deepwater Horizon oil spill provides the first comprehensive analysis and synthesis of the science used in the unprecedented response effort by the government, academia, and industry;with the benefit of hindsight and additional analyses, these papers evaluate the accuracy of the information that was used in real-time to inform the response team and the public

  • Fracking in Michigan

    In hydraulic fracturing, large amounts of water, sand and chemicals are injected deep underground to break apart rock and free trapped natural gas; though the process has been used for decades, recent technical advances have helped unlock vast stores of previously inaccessible natural gas, resulting in a fracking boom; researchers are examining the benefits of fracking for Michigan

  • Synthetic fuels could entirely eliminate U.S. need for crude oil, create new economy

    The United States could eliminate the need for crude oil by using a combination of coal, natural gas, and non-food crops to make synthetic fuel, a team of researchers has found; besides economic and national security benefits, the plan has potential environmental advantages; because plants absorb carbon dioxide to grow, the United States could cut vehicle greenhouse emissions by as much as 50 percent in the next several decades using non-food crops to create liquid fuels

  • Student invents a wireless vibration sensor which harvests energy from earthquakes

    A wireless vibration sensor being developed by an engineering student could provide a low-cost solution for engineers to monitor the damage of buildings affected by earthquakes; currently, no sensor exists in the marketplace which does not rely on batteries or electricity supply to run

  • Learning the lessons of the BP oil spill

    In an attempt to limit the harm of the Deepwater Horizon oil spill in the Gulf of Mexico in 2010, three million liters of dispersant were used to dissipate the oil; on the surface the damage seems limited, but the seabed is covered with a thick layer of gunk; scientist from around the world are now working on models that can be consulted by decision makers when there is another oil spill disaster

  • Combining CO2 storage with enhanced oil recovery can aid U.K. economy

    Combining carbon storage with enhanced oil recovery techniques in key fields could generate up to 2.7 billion pounds in extra economic output; if a combination of carbon storage and enhanced recovery techniques is fully exploited, it is estimated that nineteen potentially suitable oil fields on the U.K. Continental Shelf (UKCS) could contribute 15 percent of all UKCS oil production by 2030

  • Chemists convert greenhouse gas to fuel

    What if you could take greenhouse gas and convert it to fuel for an energy-hungry world? Scientists, using modern genetics, accomplished exactly this; the researchers’ findings are just a first step toward converting carbon dioxide, one of the most abundant emissions from fossil fuel use, into usable hydrocarbons

  • New fluorescence technology pinpoints oil leaks at sea

    Cambridge Consultants uses fertility monitor technology in oil leak early warning system; the company has built an oil spill detection technology platform which is capable of detecting the natural fluorescence of even tiny amounts of oil in or on water
