Project aims to establish supply of REEs from waste streams

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…

New catalyst for oxidative dehydrogenation of propane to propylene

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…

Compressing hydrogen electrochemically

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…

Direct metal conversion streamlines cathode-material supply chain

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…

Recycling electrolyte from vanadium RFBs

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…

Thermal-energy storage system can decarbonize industrial heat

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…

Methane-pyrolysis process leverages natural gas for CO2-free H2 generation

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…

New crushing station makes its commercial debut in Brazil

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…
