An effort is underway to establish an environmentally friendly supply of rare-earth elements (REEs) from waste streams in the U.S. The project, undertaken by American Resources Corp. (Fishers, Ind.; www.americanresourcescorp.com), is focused on re-positioning assets from the coal industry to…
Conventional propane dehydrogenation (PDH) is an endothermic, equilibrium-limited reaction that requires high temperatures to achieve commercially viable per-pass yields of propylene. Oxidative propane dehydrogenation has the potential to form propylene at much lower temperatures and more selectively by controlling the…
TeselaGen Biotechnology (San Francisco, Calif.; www.teselagen.com) has developed a platform technology that integrates software and services, while taking advantage of artificial intelligence (AI) by applying machine-learning algorithms to reduce the costs and time required for the development of biologically derived…
Typically, to achieve the high graphite purity levels demanded by lithium-ion battery (LIB) applications, processors depend on hydrofluoric acid to remove silica impurities. Now, a new graphite-purification technology that eliminates the use of highly corrosive and toxic HF is being…
Kaji Technology Corp. (Osaka; www.kajitech.com) and Toray Industries, Inc. (Tokyo, both Japan; www.toray.com) have jointly completed developing and demonstrating an electrochemical hydrogen pump system earlier this year. This effort was part of a project, funded by the New Energy and…
As application demands evolve, battery materials have gotten more complex, incorporating not only lithium, but higher nickel, manganese and cobalt content, while also including various dopants like aluminum or zirconium and stabilizing coatings. Processing all of these disparate components into…
U.S. Vanadium LLC (Hot Springs, Ark.; www.usvanadium.com) has successfully demonstrated the ability to recycle the liquid electrolyte used in vanadium redox-flow batteries (VRFB), a rapidly growing commercial technology that promises to enable intermittent renewable energy technologies, such as solar and…
A closed-loop, long-duration energy-storage system (diagram) developed by Malta, Inc. (Cambridge, Mass.; www.maltainc.com) could provide a carbon-neutral path to industrial heating. “One of the exciting facets of this technology is that it generates a lot of discharge heat. When we…
Engineering design of a demonstration plant is underway for a process that pyrolyzes natural gas into hydrogen and solid carbon. The process was developed by C-Zero Inc. (Goleta, Calif.; www.czero.energy), a company set up in 2018 to develop and commercialize…
Last month, Amarillo Gold Corp. (Toronto, Canada; www.amarillogold.com) selected Metso Outotec’s (Helsinki, Finland; www.mogroup.com) modular FIT Station for its Posse Gold greenfield mining project in the state of Goiás in central Brazil. This will be the first commercial installation of…
