Hydrogen is produced in a catalytic hydrolysis reaction of sodium borohydride (NaBH 4 ) with ruthenium powder as a catalyst. The system consists of two main chambers: an upper chamber with granulated sodium borohydride powder and a lower reaction chamber with a solution of water and catalyst. Zakhvatkin et al. 1c00367.
Researchers from Ulsan National Institute of Science and Technology (UNIST) in Korea and Karlsruher Institute of Technology in Germany have developed a novel energy conversion and storage system using seawater as a cathode. Similarly, sodium has recently attracted attention as a replacement for lithium in alkali-metal-air batteries.
Flowchart of Molten Sodium Upgrading process. A new company, Field Upgrading (Calgary, Alberta), has been formed dedicated to developing and commercializing the Molten Sodium Upgrading (MSU) technology. When electricity is applied to the ceramic membrane, elemental sodium is extracted through the membrane and recycled to the process.
The thermochemical production of hydrogen and oxygen from water via a series of chemical reactions is of interest because it directly converts thermal energy into stored chemical energy (hydrogen and oxygen), and thus can take advantage of excess heat given off by other processes. —Xu et al. NaMnO 2 at 850 °C; Na + extraction from ?-NaMnO
Schematic representation and operating principles of the lithium–water electrochemical cell used for hydrogen generation: (1) external circuit and (2) inside of lithium–water electrochemical cell. the high-school chemistry demonstration of the violent reaction between sodium and water.). sea water) by using sunlight.
The platform technology is also being commercialized for conversion of waste brines to chemicals and desalinated water. The Mangrove technology is derivative of the company’s original focus on the treatment of produced water. Mangrove says that its process recovers more than 90% of the lithium from lithium concentrates.
Researchers from Tatung and National Cheng Kung Universities in China, and Case Western Reserve University in Ohio, report manufacturing a new oxygenate additive for diesels (bio or petroleum) using glycerol (a major byproduct of biodiesel production), dimethyl sulfate (DMS), and sodium hydroxide pellets as raw materials.
Two chemists at Brown University have streamlined the conversion of waste vegetable oil (WVO) into biodiesel, eliminating the need for corrosive chemicals to perform the reactions. Current techniques for the conversion of waste vegetable oil to biodiesel take time, are costly and are inefficient. WVO to Biodiesel. —Jason Sello.
Using electrolyzed water rather than harsh chemicals could be a more effective and environmentally friendly method in the pretreatment of ethanol waste products to produce an acetone-butanol-ethanol fuel mix, according to research conducted at the University of Illinois. coli on fresh fruits and vegetables. Resources. 52(3): 885-892.
The Pilot Plant has undergone validation testing and begun Phase One operation, the results from which demonstrate highly selective, high-yield direct lithium extraction from brine and high water efficiency. SuperLig 285 is highly selective for Li over other brine constituents including magnesium, calcium, sodium, potassium and boron.
Most importantly, after full conversion of the formate, the bicarbonate solution may be recharged with hydrogen to close the cycle. Bicarbonates are a component of many natural stones and are also commonly used as baking powder or sherbet (sodium bicarbonate, NaHCO 3 ). formed in the dehydrogenation.
The new approach, described in an open access paper in the journal Biotechnology for Biofuels , potentially could significantly reduce costs of sugar production from lignocellulose by eliminating the need for costly enzymes and decreasing the water consumption requirements. Significantly reduced volume of water (.
Researchers in the Netherlands have demonstrated the direct conversion of synthesis gas through a Fischer-Tropsch process to C 2 through C 4 light olefins with selectivity up to 60 wt.% using catalysts that constitute iron nanoparticles (promoted by sulfur plus sodium) homogeneously dispersed on weakly interactive ?-alumina
Current interest areas in sustainable energy technologies are as follows: Biomass Conversion, Biofuels & Bioenergy. Advanced systems such as lithium-air, sodium-ion, as well as lithium-ion with new cathode chemistries are appropriate. Advanced Batteries for Transportation.
Researchers from George Washington University and Vanderbilt University have demonstrated the conversion of atmospheric CO 2 into carbon nanofibers (CNFs) and carbon nanotubes (CNTs) for use as high-performance anodes in both lithium-ion and sodium-ion batteries. times above that of sodium-ion batteries with graphite electrodes.

Touchstone Research Laboratory, Triadelphia, W. TerraPower LLC, Bellevue, Wash.
Current topics of interest include: Biomass Conversion, Biofuels & Bioenergy. Advanced systems such as lithium-air, sodium-ion, as well as lithium-ion electrochemical energy storage are appropriate. Advanced Batteries for Transportation and Renewable Energy Storage.
The 55kW E-Drive fits neatly onto the existing engine mounting points with just three additional connections (water, high voltage electrics and low voltage electrics). Tags: Conversions Electric (Battery) Motors. Click to enlarge.
Such a conversion has never been done, but the report is another sign that the idea is gaining momentum—if with the slow steps of a baby needing decades to learn to walk. “A Conversion backers say the process has benefits for everybody involved. On 13 September, the U.S. Either option will be an uphill battle. In Kemmerer, Wyo.,
Water (1 project). 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. Affordable Energy from Water and Sunlight. Waste Heat Capture (2 projects).
The new solar cell can be excited by incident light on sunny days and raindrops on rainy days, yielding an optimal solar-to-electric conversion efficiency of 6.53% under AM 1.5 Raindrops are not pure water; they contain salts that dissociate into positive and negative ions.
The program will encourage systems that couple large-scale physical and genetic characterization with advanced algorithms in order to accelerate the year-over-year yield gains of traditional plant breeding and the discovery of crop traits that improve water productivity, nutrient use and our ability to mitigate greenhouse gases. Description.
Others solid battery types are nickel-cadmium and sodium-sulphur, while zinc-air is emerging. Energy storage with pumped hydro systems based on large water reservoirs has been widely implemented over much of the past century to become the most common form of utility-scale storage globally. Batteries encompass a range of chemistries.
He had discovered sodium, potassium, and several compounds and invented the. While reconstructing Ørsted's experiments, Faraday was not entirely convinced that electricity acted like a fluid, running through wires just as water runs through pipes. Davy, just 13 years older than Faraday, had already made a name for himself as a chemist.
Battery: The battery is suitable for pure electric vehicles, including lead-acid batteries, nickel-metal hydride batteries, sodium-sulfur batteries, secondary lithium batteries, air batteries, and ternary lithium batteries. (1) Alkaline fuel cells consume oxygen and pure oxygen to produce drinking water, heat and electricity.
It’s basically the reason they say you’re 66 percent water or whatever. This is like sieve water. It’s got sodium, potassium, calcium, etc., It doesn’t really like sodium so much. This is a whole conversation that’s being had, but that’s one avenue. and these ions are charged particles.
Other work focuses on sodium as an earth-abundant alternative to lithium, but while it could lower cost, sodium ions also carry just a single charge. One way is to generate hydrogen by splitting water and storing the hydrogen, as in the power-to-gas schemes under examination (e.g., Rechargeable metal-air batteries.
In addition to nickel and cobalt electrolysis, the flowsheet and site encompasses leaching and neutralization, nickel purification, crystallization and evaporation, cobalt extraction, utilities, cutting and packing, electrical, maintenance, an industrial waste-water treatment plant and a sodium sulfate crystallization building.
