Storing energy to smooth the intermittency of wind and solar power can be accomplished in a number of ways, including mechanical (pumped hydro, flywheels, compressed air and others), thermochemical (phase-change materials and molten salts, for example), chemical (conversion of electricity…
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…
Conscientious operation and maintenance is critical for steam-generator system reliability. Here, important details for softening and reverse osmosis systems are explained and compared As steam generation technology and higher pressure and temperature boilers evolved in the 20th century, improved makeup-water-treatment…
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…
