A new flow-battery design is based on quinones — a plentiful material historically derived from coal tar and used in dyestuff manufacturing — rather than traditional battery electrolytes. “Our feedstocks use no critical materials like lithium, cobalt or nickel, and…
Flashing occurs when the pressure of a fluid passing through a valve is lower than the same substance’s vapor pressure. This causes the fluid to boil — otherwise known as “flashing.” “By reducing flow capacity and eroding the valve itself,…
When searching for catalysts for the energy transition, materials consisting of at least five elements — so-called high-entropy alloys (HEAs) — are considered highly promising. But to find the right combination of elements and composition ratios needed for the best…
The production of substitute (or synthetic) natural gas (SNG) by methanation of CO2 with hydrogen is energy intensive and also requires a purification step to remove the byproduct water and remaining reactants. To address these issues, researchers at The Swiss…
Recovering valuable metals, such as cobalt and nickel, from used lithium-ion batteries is emerging as a key capability because of anticipated high battery demand and material shortages. Researchers at Lawrence Berkeley National Laboratory (Berkeley, Calif.; www.lbl.gov) have developed a technology…
Perovskite materials have great potential as a lightweight and low-cost option for solar panels, but in the past have not been seen as stable or durable enough for widespread use in large-scale solar-power installations. Now, a new coating developed by…
ODC Technology Last month, Covestro AG (Leverkusen, Germany; www.covestro.com) started up a new world-scale facility for the production of chlorine in Tarragona, Spain. It is the first world-scale production plant for chlorine based upon the oxygen-depolarized cathode (ODC) technology invented…
A recently commissioned, 150,000-ton/yr facility in Sumner, Wash. is the first wastewater-treatment plant to deploy a new liquid-waste treatment technology. Owned by Generate Upcycle (San Francisco, Calif.; www.generatecapital.com), and operated in partnership with Sedron Technologies, LLC (Sedro-Woolley, Wash.; www.sedron.com), the…
Processes that capture carbon dioxide from industrial fluegas and simultaneously convert it into useful chemicals are desirable because they offer an opportunity to produce CO2-derived chemicals more efficiently and economically than conventional approaches, where costs are driven up by the…
Coil coating is a continuous process for producing prepainted sheets of metal (steel or aluminum), which can then be fabricated into various building and other materials. Because organic coating materials are used, the process requires substantial energy for the curing…
