Field trials are expected to begin shortly for a high-temperature thermal-storage demonstrator built by AED Energy (London, U.K.; www.aedenergy.com). The field trials follow the successful completion of a test program of the demonstrator at AED’s London facility. The test program,…
Black mass is the powdered material resulting from shredding end-of-life lithium-ion vehicle batteries. For effective recycling, lithium must be efficiently separated from this material, but conventional methods, such as smelting at high temperatures or dissolving in strong acids, require large…
Several situations, including when takeaway capacity is limited at remote oil-well sites, result in methane flaring. To avoid wasting that resource, several strategies have been explored to convert methane onsite into commercially useful liquid chemicals. One of the approaches is…
A first-of-its-kind demonstration unit is showcasing hydrogen liquefaction using magnetocaloric cooling, a process that demands much lower energy consumption than conventional methods used in industry. A joint venture between Magnotherm Solutions GmbH (Darmstadt, Germany; www.magnotherm.com) and Helmholtz-Zentrum Dresden-Rossendorf (HZDR; Dresden,…
Pharmaceutical residues, particularly from antibiotics, are extremely difficult to fully remove from wastewater using traditional bulk-treatment methods, wherein antibiotic compounds are often only partially broken down. Even at trace amounts, antibiotic fragments can accumulate and wreak havoc on natural ecosystems.…
Increased concern around per- and polyfluoroalkyl substances (PFAS) in water is necessitating more robust mitigation techniques. There are many technologies that can effectively capture or destroy PFAS, but challenges remain surrounding large volumes of PFAS-laden solid waste and fluorinated byproducts.…
Palladium is widely used in membrane applications because of its extreme selectivity for hydrogen. However, conventional palladium membranes can be damaged at the high temperatures required for many processes that generate hydrogen for various subsequent uses, including the manufacture of…
By replacing traditional silicon or graphite anode materials with specially crystallized niobium, manufacturers can overcome some of the safety and power limitations of traditional lithium-ion batteries (LIBs). Echion Technologies Ltd. (Cambridge, U.K.; www.echiontech.com) has developed a proprietary mixed niobium-oxide active…
Siloxanes — synthetic chains of alternating silicon and oxygen atoms — are widely used in personal care products, soaps, pharmaceutical formulations and other products, but are notoriously difficult to manage in production- and waste-fluid streams. Current approaches, including flaring and…
The widely used plastic polyethylene terephthalate (PET) can be depolymerized by reacting it with sodium hydroxide (NaOH) under strong mechanical impact from metal spheres in a ball mill. This type of mechanochemical route to recycling could alleviate some of the…
