Minimizing cost is the key parameter for the viability of direct-air-capture (DAC) systems that remove carbon dioxide from the atmosphere. The startup company Sustaera Inc. (Research Triangle Park, N.C.; www.sustaera.com) has built a prototype DAC system that it says can…
A new approach to advanced recycling combines heterogeneous catalysis with electromagnetic induction, enabling the conversion of polyolefin-rich waste streams into versatile materials. Developed by bobine (Strasbourg, France; www.bobine-chemistry.com), this fully electric technology can help decarbonize the production of olefins like…
A new demonstration facility in northern Iceland will integrate geothermal energy with a solid-oxide electrolyzer cell (SOEC) to produce green hydrogen, representing a key step toward lower-cost sustainable aviation fuel (SAF). This Thermal Hybrid Production System, developed by Syntholene Energy…
Extracting lithium from currently underutilized brines, such as geothermal and oilfield brines, will be necessary to meet the growing demand for lithium in energy-storage applications in the future. Technical hurdles for extracting lithium from these sources include the relatively low…
Current recycling methods for recovering platinum-group metals (PGMs) from catalyst-coated membranes (CCMs) used in proton-exchange membrane (PEM) electrolyzers and fuel cells incinerate the highly valuable membrane material, requiring the manufacture of new material and the management of hydrogen fluoride offgas…
Olefin epoxidation is an important reaction for making a range of industrial intermediates in processes for epoxy coatings, polyurethanes, polyester textiles, surfactants, specialty chemicals, pharmaceuticals and others. Conventional olefin epoxidation involves organo-peroxides or organo-halogen oxidants, which present safety and environmental…
Traditional methods for making graphite involve heating premium needle coke and coal-tar pitch at temperatures above 3,000ºC in a process that requires several days of heating and cooling. A new process developed by researchers at the National Energy Technology Laboratory…
Calcining limestone (CaCO3) to produce lime (CaO) is a key industrial process for making cement, steel and chemicals, among other uses. Lime production is a target for CO2-abatement efforts because it generates a great deal of CO2 emissions, not only…
Flow batteries have been widely deployed in large-scale energy-storage applications in recent years, but the low energy density and high cost of the incumbent vanadium electrolyte limit the long-term return on investment of such systems. A new organic redox flow-battery…
A new process called BioSintering takes advantage of plant-based bio-active molecules to fuse together particles at mild temperatures, yielding an alternative material for conventional ceramic tiles with a much lower carbon footprint. Developed by Dekiln (Manchester, U.K.; www.dekiln.com), the technology…
