Energy policy

  • EnergyWhich fossil fuels must remain in the ground to limit global warming?

    A third of oil reserves, half of gas reserves, and over 80 percent of current coal reserves globally should remain in the ground and not be used before 2050 if global warming is to stay below the 2°C target agreed by policy makers, according to new research. The study also identifies the geographic location of existing reserves that should remain unused and so sets out the regions that stand to lose most from achieving the 2°C goal.

  • EnergyUnited States must seize opportunity to build sustainable energy system: IEA

    The United States is in a strong position to deliver a reliable, affordable, and environmentally sustainable energy system, the International Energy Agency (IEA) said, as it released a review of U.S. energy policy. To do so, however, the country must establish a more stable and coordinated strategic approach for the energy sector than has been the case in the past.

  • EnergyStoring hydrogen underground could boost transportation, energy security

    Large-scale storage of low-pressure, gaseous hydrogen in salt caverns and other underground sites for transportation fuel and grid-scale energy applications offers several advantages over above-ground storage, says a recent Sandia National Laboratories study sponsored by the Department of Energy’s Fuel Cell Technologies Office. Geologic storage of hydrogen gas could make it possible to produce and distribute large quantities of hydrogen fuel for the growing fuel cell electric vehicle market.

  • FrackingUsing earthquake research to refine fracking methods

    Researchers at Oklahoma State University (OSU) are using historical earthquake data to make oil and natural gas drilling more efficient. Members of the university research team found that hydraulic fracturing, or fracking, a process in which water and sand are blasted at high pressure into rock to remove oil, can cause an effect similar to earthquakes. Data gleaned from historical earthquake experiences have told scientists much about what happens to the rock during such events – and the knowledge may allow oil companies to understand how to extract gas without also removing groundwater.

  • EnergyGas can be a “bridge fuel” to a low-carbon future

    Major new suggests that gas could play an important role as a “bridging fuel” to a low-carbon economy, but warns that it will not be long before gas becomes part of the problem rather than the solution. The research combines the latest energy system modelling techniques with analysis of U.K. gas security to assess future demand.

  • EnergyState, federal role in electric utilities’ labor issues should be reexamined: Study

    Power outages have never been more costly. Electricity is critical to communication, transportation, commerce and national security systems, and wide-spread or prolonged outages have the potential to threaten public safety and cause millions, even billions, of dollars in damages. This is why it may be time to re-examine the role of public utility commissions and the effect of the National Labor Relations Act in labor disputes regarding electric utilities, a new study suggests.

  • Power supplyLights out: Experts say instability of world’s power supplies must be urgently addressed

    A new study reveals the urgent need to address instabilities in the supply of electrical power to counteract an increase in the frequency and severity of urban blackouts. The work builds on previous studies which examined a sharp increase in electrical usage over recent years, and warned the world to prepare for the prospect of coping without electricity as instances of complete power failure become increasingly common.

  • HazmatPetroleum industry, railroads want deadline extension for phasing out old tank cars

    Transportation of crude oil by train jumped to 408,000 in 2013, from 11,000 in 2009, partly due to the rise in production from North Dakota’s Bakken region, where oil production has surpassed pipeline capacity. The increasing use of rail to transport crude oil has resulted in several accidents. The Department of Transportation want to phase out older tank cars — because they have thinner shells and are thus more vulnerable to accidents when transporting flammable liquids like crude oil – and replace them with new, safer tank cars with thicker shells. The petroleum industry and U.S. railroads want DOT to extend the deadline for phasing out old tankers from two years to four years.

  • EnergyMore stringent climate policies mean hard choices for coal plant operators

    Limiting climate change to 2°C means shutting down coal power plants — an unpopular proposition for coal power companies. A new study shows, however, that delaying climate policies could prove even worse for power plant owners. The reason: new power plants being built now, especially in China and India, are built to run for 30-50 years, paying off only after years of operation. Stringent climate policies, however, could make the cost of emission so high that coal power generation is no longer competitive, leaving new power plants sitting idle and their owners and investors with huge losses — a problem known as stranded capacity.

  • EnergyControversial 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.

  • EnergySmall 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.

  • EnergyAdvancing 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.

  • EnergyU.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.

  • Energy50-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.

  • Geothermal energyPromising geothermal resources found on Akutan Island, Alaska

    Akutan Island, in Alaska’s east-central Aleutian Islands, hosts the City of Akutan and is home to the largest seafood production facility in North America. It also hosts Akutan Volcano, one of the most active volcanoes in the United States. During July 2012 the geochemistry of the hot springs on Akutan Island was studied in detail for the first time since the early 1980s. The results from this study document higher concentrations of hydrothermal components in the hot spring waters and an increase in water discharge from the hot spring system. The current heat output of the hot spring system is estimated at twenty-nine megawatts — nearly ten times higher than measured in the early 1980s. This large increase may reflect the volcanic and seismic events of the 1990s, and if so, it cannot be considered a short-term anomaly. Modern geothermal plants could use this heat to generate several MW of electricity. One MW of electric power would supply the needs of about 750 homes.
