• U.S. nuclear industry faces a wave of nuclear power station retirements

    A wave of U.S. nuclear power station retirements is on the horizon. The typical design life of a nuclear power plant is 40 years. There are 104 nuclear power plants in the United States, and their average age is 34 years — only a few years short of, and fast approaching, their design life. Almost 30 U.S. commercial and research reactors already have started decommissioning. A $400 million is regarded as the bargain basement price tag for cleaning up a single reactor.

  • Using waste heat to capture CO2 before it goes up in smoke

    Power plants fired by coal and natural gas account for about half of the CO2 that humans add to the atmosphere each year; these power plants are prime candidates for new technology that captures CO2 before it goes up in smoke. Researchers seek to optimize CO2 removal from power plant emissions by employing waste heat. This is just one example of looking to improve upon a tried-and-true technology for CO2 capture. That technology — a two-phase chemical process — has been used for decades to remove naturally occurring CO2 from natural gas.

  • U.S. to cut mineral payment to states by $110 million between now and August

    The U.S. Department of Interior  will cut its federal mineral payments to thirty-five states by $110 million due to the federal budget cuts. Different states will lose different amounts of money: Wyoming tops the list with $53 million in lost federal mineral payments over the next five months, while North Carolina is bringing up the rear, with the federal government cutting its mineral payments to the state by $7 (seven dollars) between now and August.

  • Coming soon: fuel made directly from CO2 in the atmosphere

    Excess carbon dioxide in the Earth’s atmosphere created by burning of fossil fuels is a major driving force of global climate change. Now, researchers have found a way to transform the carbon dioxide trapped in the atmosphere into useful industrial products – including biofuels made directly from the carbon dioxide in the air.

  • Fluctuating wind power as a solution rather than a problem

    Incorporating wind power into existing power grids is challenging because fluctuating wind speed and direction means turbines generate power inconsistently. Coupled with customers’ varying power demand, many wind-farm managers end up wasting power-generation capacity and limiting the service life of turbines through active control in order to avoid any possible damage to the power grid from spikes in supply.

  • Day of the nuclear battery nears

    Experts in nuclear physics have helped develop research toward a “nuclear battery,” which could revolutionize the concept of portable power by packing in up to a million times more energy compared to a conventional battery.

  • New technology for carbon-dioxide capture, clean coal reaches milestone

    An innovative new process which releases the energy in coal without burning — while capturing carbon dioxide, the major greenhouse gas — has passed a milestone on the route to possible commercial use.

  • Instead of a renaissance, U.S. nuclear energy industry is facing tough times

    Five years ago, U.S. nuclear industry executives and energy industry analysts talked about an American nuclear renaissance, with up to twenty new reactors to be added to the nation’s stock. Things are very different today, however, and the U.S. nuclear energy industry, rather than expanding, is fighting to hold on.

  • Coal and U.S electric power generation

    Coal is an important fuel source in the United States today. Responsible for approximately 39 percent of the country’s electrical generation, coal is vital to the day-to-day operation of people’s lives. The United States is rich in coal deposits, with large resources.  One of the most important and largest of those deposits is found in the Powder River Basin (PRB) of Wyoming and Montana, which, in 2012, produced more than 42 percent of the nation’s coal.

  • Modified bacteria turn bio waste into fat for fuel

    “Green” chemistry developed at Rice University is at the center of a new government effort to turn plant waste into fatty acids and then into fuel. A new project aims to develop a new generation of renewable energy and bio-based products from switchgrass and forestry residues and from a new hybrid of sorghum.

  • Much less additional land available for biofuel production

    Amid efforts to expand production of biofuels, scientists are reporting new estimates that downgrade the amount of additional land available for growing fuel crops by almost 80 percent.

  • Wind power’s contribution has been overestimated

    People have often thought that there is no upper bound for wind power — that it is one of the most scalable power sources. After all, gusts and breezes do not seem likely to “run out” on a global scale in the way oil wells might run dry. Yet the latest research in mesoscale atmospheric modeling  suggests that the generating capacity of large-scale wind farms has been overestimated.

  • Hydroelectric power generation superior to nuclear and coal, beats oil and gas

    Researchers have reviewed the economic, social, and environmental impact of hydro, coal, oil, gas, and nuclear power. Each has its advantages and disadvantages, but of these conventional electricity generation technologies, hydroelectric power appears to be the most sustainable and acceptable environmentally and economically.

  • New clean coal technology provides energy without burning

    A new form of clean coal technology reached an important milestone recently, with the successful operation of a research-scale combustion system. The technology is now ready for testing at a larger scale. For 203 continuous hours, the combustion unit produced heat from coal while capturing 99 percent of the carbon dioxide produced in the reaction.

  • Novel nanosized antenna arrays key to effective harvesting of solar energy

    For years, scientists have studied the potential benefits of a new branch of solar energy technology that relies on incredibly small nanosized antenna arrays that are theoretically capable of harvesting more than 70 percent of the sun’s electromagnetic radiation and simultaneously converting it into usable electric power. A novel fabrication technique could provide the breakthrough technology scientists have been looking for to improve today’s solar energy systems.
