The Netherlands-based startup company Ore Energy (Amsterdam, the Netherlands; www.oreenergy.com) recently announced that it has successfully connected its flagship iron-air battery system to the electric grid in the city of Delft, the Netherlands. It is the first iron-air battery system…
Breaking the stable carbon-fluorine bonds within per- and polyfluoroalkyl substances (PFAS) is one of the most significant challenges in mitigating persistent PFAS pollution. The Hydrothermal Alkaline Technology (HALT; diagram), invented at the Colorado School of Mines (Golden, Colo.; www.mines.edu) and…
The production of “green” hydrogen via electrolysis is seen as a key decarbonization pathway for certain industry sectors, but its efficiency can be hampered by a number of factors, including the accumulation of gas bubbles on electrode surfaces within electrolyzers…
Extremely high-salinity water streams present difficulties for many types of processing equipment, such as membranes and filters, and most commercial treatment methods involve thermal evaporators or crystallization, which are energy-intensive and require special anti-corrosion materials. A new membrane-less, non-evaporative process…
The growing need for energy-storage solutions for a gamut of applications from electronic devices to large-scale energy systems has spurred an increase in research for innovative technologies. Considerable attention is being given to new chemistries beyond the widely used lithium-ion…
A patent-pending material developed at the Technical University of Munich (TUM; www.tum.de) has achieved the fastest-ever conductivity of lithium ions, and is now poised to significantly improve the efficiency of future solid-state batteries. Solid-state batteries, often seen as a more…
Manufacturing traditional cement for concrete is responsible for a sizeable (~8%) portion of overall global CO2 emissions. Meanwhile, anthropogenic global warming is driving the need for housing structures capable of withstanding hurricane-force winds and wildfires. The cement technology company Eco…
In the catering industry, refined cooking oils (those that have undergone a process to remove lower-boiling-point impurities) are used and re-used in frying. Despite the refining process, high temperatures cause the oils to oxidize, creating polar compounds that degrade the…
Due to rising demand and widespread supply-chain turmoil, researchers around the world are investigating creative methods to obtain rare-earth elements (REEs) and other critical minerals and metals (CMMs). The ash from combusting coal has previously been seen as a potential…
Magnesium metal is a critical ingredient for aluminum alloys and it is widely used for desulfurization in steelmaking processes. Most magnesium metal is produced in China via high-energy-consumption processes. Now, technology company Magrathea (San Francisco, Calif.; www.magratheametals.com) has developed a…
