In January 2011, the Energy Information Administration released a preview of its Annual Energy Outlook. One result of the outlook: the U.S. has twice the amount of projected recoverable natural gas than previously thought, totaling 827 trillion cubic feet. Not only is the gas supply apparently abundant, but other reasons for power players to investigate gas alternatives also exist.
In September 2010, the Martin Next Generation Solar Energy Center generated its first solar-powered steam and has been providing heat to reduce a nearby combined cycle power plant’s fossil fuel consumption ever since. The Florida Power and Light-owned and operated solar thermal power plant is among the world’s first hybrid solar plants to connect to an existing power plant.
The Fukushima Daiichi nuclear plant accident in Japan is widely expected to slow new plant development efforts in a number of countries. The events also may impact existing plants, either via temporary or permanent shutdowns of some aging units or via design and procedure modifications to enhance plant safety.
Personnel at the 380 MW Safe Harbor hydroelectric plant discovered a gap between a wicket gate stem and bearing surface in one unit. To temporarily repair the unit, personnel inserted pieces of steel pipe in the gap and welded them in place. The repair functioned successfully during high spring flows. Safe Harbor Water Power Corp. is now working to determine whether to rehabilitate the unit or install a new runner.
Researchers from Northwestern University and Argonne National Laboratory have a better understanding of a common freshwater alga and its ability to remove strontium from water. Insight into this mechanism could help scientists design methods to remove radioactive strontium from existing nuclear waste.
In the U.S. today, electricity from coal fired plants is hindered due to environmental issues especially CO2 emissions. Biomass, in its various forms, including clean wood waste, and agriculture crop residue is considered CO2 neutral in most jurisdictions and are acceptable as an alternative fuel by many state Renewable Energy Portfolio Standards.
