  • Controversial Mississippi power station to cut emissions by more than half

    A new $5 billion state-of-the-art power facility is under construction Kemper County, Mississippi. It places a firm bet on the future of carbon-capture technology, and other technological advancements, including: it utilizes the gasification process with carbon in unique ways; it recycles treated wastewater to generate power; and it makes money from the carbon dioxide it has removed by selling it to oil companies for their own extraction. Critics say that investing so much money in untested technologies is too much of a gamble.

  • Shale may offer long-term home for nuclear waste

    About 77,000 tons of spent nuclear fuel currently sit in temporary above-ground storage facilities, and it will remain dangerous for tens or hundreds of thousands of years or longer. Experts say that since the U.S. government abandoned plans to develop a long-term nuclear-waste storage site at Yucca Mountain in Nevada in 2009, finding new long-term storage sites must be a priority. Shale deep under the Earth’s surface could be a solution. France, Switzerland, and Belgium already have plans to use shale repositories to store nuclear waste long-term.

  • Methane from Deepwater Horizon oil spill has entered food web

    When millions of gallons of oil spilled into the Gulf of Mexico four years ago, so did large volumes of methane, or natural gas. Now, researchers have confirmed that methane-derived carbon has entered the Gulf’s food web through tiny organic particles floating in the Gulf. The presence of methane is not cause for alarm though, the researchers said. Overall, it has a benign impact on the food that makes it from the sea to people’s dinner tables.

  • Libyan PM escapes country after assembly ousts him over oil tanker fiasco

    Libya’s General National Congress has approved a no-confidence motion against Prime Minister Ali Zeidan and designated the defense minister as acting prime minister. Zeidan left Libya after the vote, in all likelihood for Italy. The no-confidence vote came after a North Korean-flagged tanker named Morning Glory managed to sail away from the port of al Sidra, carrying 234,000 barrels of crude oil from rebel-held oil fields. Last summer, armed militias in east Libya took over most of the country’s oil fields – and also three ports, with partial control of a fourth — bringing oil exports, which had amounted to 1.6 million barrels a day, to a halt. U.S. describes oil sale by the militias as “theft” from the Libyan people.

  • East Europe’s natural gas networks vulnerable during conflicts and crises

    Gas networks in Eastern European countries, such as Ukraine and Belarus, are less resilient than the U.K. gas networks during conflicts and crises, according to new research. The authors suggest that a decentralized approach to managing congestion on gas pipeline networks could be crucial for energy security during geopolitical conflicts or natural disasters, for example.

  • Small biomass power plants could help rural economies, stabilize national power grid

    As energy costs rise, more Americans are turning to bioenergy to provide power to their homes and workplaces. Bioenergy is renewable energy made from organic sources, such as biomass. Technology has advanced enough that biomass power plants small enough to fit on a farm can be built at relatively low costs. Researchers have found that creating a bioenergy grid with these small plants could benefit people in rural areas of the country as well as provide relief to an overworked national power grid.

  • Experts call for a new organization to oversee grid’s cybersecurity

    In 2013, U.S. critical infrastructure companies reported about 260 cyberattacks on their facilities to the federal government. Of these attacks, 59 percent occurred in the energy sector. A new report proposes that energy companies should create an industry-led organization to deflect cyber threats to the electric grid. Modeled after the nuclear industry’s Institute of Nuclear Power Operations, the proposed organization, to be called the Institute for Electric Grid Cybersecurity, would oversee all the energy industry players that could compromise the electric grid if they came under a cyberattack.

  • Large offshore wind farms could weaken hurricanes before they make landfall

    Computer simulations have shown that offshore wind farms with thousands of wind turbines could have sapped the power of three real-life hurricanes, significantly decreasing their winds and accompanying storm surge, and possibly preventing billions of dollars in damages. For example, an array of 78,000 wind turbines off the coast of New Orleans would have significantly weakened Hurricane Katrina well before it made landfall, reducing wind speeds between 80 and 98 mph, and decreasing the storm surge by up to 79 percent.

  • Advancing algae’s viability as a biofuel

    Lab success does not always translate to real-world success. A team of scientists, however, has invented a new technology that increases the odds of helping algae-based biofuels cross that gap and come closer to reality. The current issue of Algal Research showcases the team’s invention — the environmental photobioreactor. The ePBR system is the world’s first standard algae growing platform, one that simulates dynamic natural environments.

  • Not much is known about long-term health effects of chemical leaked in W.Va.

    In January, 10,000 gallons an obscure chemical called 4-methylcyclohexanemethanol, or MCHM, used in processing coal, leaked from storage tanks into the nearby Elk River in the Charleston, West Virginia area, contaminating the water of more than 300,000 residents for days. To what degree MCHM affects long-term human and fetal health is a major concern for residents because of the lack of complete toxicology and other studies on the chemical.

  • U.K. could generate half its energy needs from currently underutilized bioenergy sources

    The United Kingdom could generate almost half its energy needs from biomass sources, including household waste, agricultural residues, and home-grown biofuels by 2050, new research suggests. Scientists found that the United Kingdom could produce up to 44 percent of its energy by these means without the need to import. The new study highlighted the U.K. potential abundance of biomass resources that are currently underutilized and totally overlooked by the bioenergy sector.

  • 50-state roadmap to renewable energy unveiled

    Researchers recently developed detailed plans to transform the energy infrastructure of New York, California, and Washington states from fossil fuels to 100 percent renewable resources by 2050. The new roadmap to renewable energy for all fifty states was presented on 15 February at the annual meeting of the American Association for the Advancement of Science (AAAS) in Chicago. The online interactive roadmap is tailored to maximize the resource potential of each state.

  • Iran-Russia oil deal threatens nuclear negotiations

    Iran said that in exchange for Iranian oil, Russia could build a second reactor at Iran’s Bushehr nuclear power plant. Russia could also provide Iran with trucks, railroad tracks, mini-refineries, grain, and other goods for Iranian oil. In a deal worth $1.5 billion a month, Iran would export 500,000 barrels of oil per day to Russia. The deal would increase Iran’s oil exports, which have been reduced to about one million barrels a day by American and European sanctions aimed at curbing Iran’s nuclear program.

  • Power cuts will be more common in the future

    U.S. figures show that since 2007, commercial and domestic air-conditioning alone consumed 484billion kilowatt hours of electricity — not much more than the country’s total energy consumption in the mid-1950s. The American Society of Civil Engineers (ASCE) has warned that U.S. generation systems could collapse by 2020 without $100 billion of new investment in power stations. Demands of high-powered electrical appliances, a growing world population, and inadequate investment in the power sector will create more frequent power blackouts in Western societies.

  • Micro-windmills to recharge cell phones, used for home energy generation

    Researchers have designed a micro-windmill that generates wind energy and may become an innovative solution to cell phone batteries constantly in need of recharging, and home energy generation where large windmills are not preferred. The device is about 1.8 mm at its widest point. A single grain of rice could hold about ten of these tiny windmills. Hundreds of the windmills could be embedded in a sleeve for a cell phone.
