Using a novel, reusable carbon material derived from old rubber tires, an Oak Ridge National Laboratory (ORNL)-led research team has developed a simple method to convert used cooking oil into biofuel. The patent-pending, waste oil-to-biofuel conversion adds a new approach to waste tire recycling initiatives. —Hood et al.
The platform technology is also being commercialized for conversion of waste brines to chemicals and desalinated water. Mangrove’s modular solution can be scaled to any capacity and co-located with upstream lithium producers or cathode and cell manufacturers. The process creates an effluent stream with salinity below 3,000 ppm.
Department of Energy (DOE) released a report suggesting that, in theory, over 300 former and present coal power plants could be converted to nuclear. 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
Researchers in Sweden and Spain have devised a three-step process for the conversion of precipitated kraft lignin from black liquor into green diesel. The kraft process converts wood into wood pulp for paper production. Their paper appears in the journal ChemSusChem. tons of black liquor dry solids.
The resulting aqueous bicarbonate solution can be catalytically converted to a formate solution under much milder conditions than those required for reactions of methanol or methane. Most importantly, after full conversion of the formate, the bicarbonate solution may be recharged with hydrogen to close the cycle.
Current interest areas in sustainable energy technologies are as follows: Biomass Conversion, Biofuels & Bioenergy. Photosynthetic processes used by plants or algae use sunlight to convert atmospheric CO 2 to energy-rich metabolites (carbohydrates, lipids, or hydrocarbons) which can be processed into transportation fuels.
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
In industry, molecular hydrogen and reactive reagents such as sodium borohydride are used as reducing agents during the production of pharmaceuticals, agrichemicals and ammonia for fertiliser. A future aim is to try to convert carbon dioxide into methanol much more efficiently. —Stephen Colbran. McSkimming, A., Bhadbhade, M.
published in the ACS journal Chemical Reviews , reviews in detail four stationary storage systems considered the most promising candidates for electrochemical energy storage: vanadium redox flow; sodium-beta alumina membrane; lithium-ion; and lead-carbon batteries. Sodium-beta alumina membrane battery. In their study, Yang et al.
It is usually associated with other lithium minerals; spodumene has a chemical composition of LiAlSi 2 O 6 but small amounts of sodium sometimes substitute for lithium. Once concluded, the revised terms will see MinRes responsible for operating Wodgina and Albemarle responsible for operating downstream conversion assets. Mt Marion.
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. NaMnO 2 at 850 °C; Na + extraction from ?-NaMnO
Although direct chemical reactions between water and certain metals—alkali metals including lithium, sodium and others—can produce a large amount of hydrogen in a short time, these reactions are too intense to be controlled. the high-school chemistry demonstration of the violent reaction between sodium and water.).
Chemical energy storage mainly includes lead-acid batteries, nickel batteries, lithium batteries, liquid flow batteries, and sodium-sulfur batteries, and electromagnetic energy storage mainly includes supercapacitor energy storage and superconducting energy storage. What is a battery?
The rule gives new certainty to a number of companies across the nation that are commercializing algae-based technologies that convert carbon dioxide generated at power plants into fuels, feeds, fertilizers and other valuable products.”. Several commenters also suggested that algae-based CCU (i.e.,

chemical, kinetic, or thermal) and convert them back to useful forms of energy like electricity. Others solid battery types are nickel-cadmium and sodium-sulphur, while zinc-air is emerging. Energy storage with hydrogen, which is still emerging, would involve its conversion from electricity via electrolysis for storage in tanks.

Charged : Do different companies handle different steps of the process that converts spent battery packs to minerals? There are real challenges with waste streams—they yield a lot of sulfuric acid and sodium sulfate, which will need to get landfilled. The output consists of those critical battery minerals and metals.
The batteries that use sodium instead of the pricey and rare lithium are the ones that are the closest to being on the market.

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. This allows storage of charge at a higher volumetric or gravimetric density, which translates to a higher stored energy density or storage capacity for a given size or weight.
