Produced water from coal-bed natural gas (CBNG) production may contain sodium bicarbonate (NaHCO 3 ) at concentrations that can harm aquatic life, according to a new study by the US Geological Survey; Montana Fish, Wildlife and Parks; the Bureau of Land Management and the US Environmental Protection Agency.
A typical example is the use of a dilute aqueous sodium hydroxide (NaOH) solution to absorb SO 2 from flue gas, forming an aqueous Na 2 SO 3 solution. Linkous, Olawale Adebiyi and Ali T-Raissi (2010) Hydrogen Production via Photolytic Oxidation of Aqueous Sodium Sulfite Solutions. Huang et al. Cunping Huang, Clovis A.
On a planet aspiring to become carbon neutral, the once-stalwart coal power plant is an emerging anachronism. It is true that, in much of the developing world, coal-fired capacity continues to grow. But in every corner of the globe, political and financial pressures are mounting to bury coal in the past.
ARPA-E selected the following 12 teams from universities, national laboratories and the private sector to address and remove key technology barriers to EV adoption by developing next-generation battery technologies: 24M Technologies will develop low-cost and fast-charging sodium metal batteries with good low-temperature performance for EVs.
In trials, GE’s sodium metal halide Durathon batteries ( earlier post ) have successfully powered GE Mining’s Scoop, an underground vehicle that transports mining materials, at Coal River Energy, LLC in Alum Creek, West Virginia. Sodium-metal halide cell basic chemistry. Click to enlarge.
TerraPower and PacifiCorp announced efforts to advance a Natrium reactor demonstration project at a retiring coal plant in Wyoming. The Natrium technology has a 345MW sodium fast reactor coupled with a molten salt-based integrated energy storage system that will provide clean, flexible energy and stability for the grid.
The plant uses natural gas instead of coal as the main energy source; realizes 100% recycling and recycling of condensed water; encourages the utilization of by-products, and transports products such as calcium silicate slag, sodium sulfate, calcium sulfate slag, etc. produced during the production process.
TerraPower is experiencing terrific growth, partially driven by the US Department of Energy’s Advanced Reactor Demonstration Program (ARDP) award ( earlier post ) and the construction of the Natrium demonstration plant at a retiring coal facility in Wyoming ( earlier post ).
Only about 3% currently is generated from wind, solar, hydroelectric and other renewable sources, with most of the electricity produced in the United States currently coming from coal- and natural gas-fired power plants, followed by nuclear according to data from the US Energy Information Administration (EIA).
using catalysts that constitute iron nanoparticles (promoted by sulfur plus sodium) homogeneously dispersed on weakly interactive ?-alumina Although Fischer-Tropsch (F-T) synthesis can convert coal-, biomass-, and natural gas-derived synthesis gas into hydrocarbon derivatives, selectivity toward lower olefins tends to be low.
The process produces a toxic byproduct referred to as black liquor—a primarily liquid mixture of pulping residues (such as lignin and hemicellulose) and inorganic chemicals from the Kraft process (sodium hydroxide and sodium sulfide, for example). tons of black liquor dry solids. Globally over 1.3 Earlier post.)
But a new way to firm up the world’s electricity grids is fast developing: sodium-ion batteries. Sodium-ion batteries: pros and cons Energy storage collects excess energy generated by renewables, stores it then releases it on demand, to help ensure a reliable supply. Sodium ions are bigger and heavier than lithium ions.

It’s being constructed near the retiring coal-fired Naughton power plant and is the world’s only coal-to-nuclear project under development. TerraPower, which will employ between 200 and 250 people at the Natrium facility, wants to hire the 110 former coal workers to tap into their transferrable skills. Get started here.
MPa enable the system to operate with very high thermal efficiency, exceeding even those of a large coal-generated power plant and nearly twice as efficient as that of a gasoline engine (about 25%). Sienicki (2009) Investigation of alternative layouts for the supercritical carbon dioxide Brayton cycle for a sodium-cooled fast reactor.
Demonstration of Sodium Ion Battery for Grid Level Applications. Specifically, an aqueous sodium-ion based electrolyte is used in conjunction with simple highly scalable electrode materials housed in low cost packaging. . $10,792,045. 44 Tech Inc. (PA). 10,000,000. City of Painesville (OH). 7,487,153.
Eagle Picher, in partnership with the Pacific Northwest National Laboratory, will develop a new generation of high energy, low cost planar liquid sodium beta batteries for grid scale electrical power storage applications. Energy Efficient Capture of CO 2 from Coal Flue Gas. DOE grant: $7,200,000). DOE grant: $3,111,693).
Liquid sodium is used as a coolant because it does not slow down neutrons as much as water does. The new breeder reactors in China, meanwhile, are demonstration projects, the second step in a three-step program to develop fast breeder reactors to reduce the country’s dependence on coal.
Improving hydrogen-from-coal technologies, including developing membranes for separation and purification that show the potential, at laboratory scale, to achieve the 2010 technical targets for flux (200 ft 3 /hr/ft 2 ).
Many of you write to us about the long tailpipe of electric vehicles and coal is major source of electricity generated in India. Studies from independent scientists tell us that even if 100% of Electricity is generated from coal, EV’s emit 50% lesser carbon gases due to the efficiency of the electric motor. .
Poor women and children pay a heavy price from indoor air pollution since they spend more time at home breathing in smoke and soot from leaky coal and wood cook stoves. million deaths in 2012 in households cooking over coal, wood and biomass stoves.
