A polarizable membrane for improved energy storage

The two basic energy-storage devices — dielectric and double-layer capacitors — entail serious limitations. Dielectric capacitors have low capacitance, on the order of 0.1 to 1.0 µF/cm2, while the double-layer capacitor has a high capacitance, on the order of 0.5…

U.S. production is scheduled for a critical metal

China produces about 98% of the world’s electrolytic manganese metal (EMM), a vital ingredient used in specialty steels, aluminum and electronics. In contrast, the U.S. produces no EMM, says Nick Weir, an executive with U.S. American Manganese Inc. (AMY; White…

Slash sewage-sludge volumes with this add-on digester

A 60% reduction in the sludge volume was achieved at the sewage treatment plant of Noboribetu City, Hokkaido, Japan, after installing a Bio-Diet SBD-1200 system from Nippon Steel Kankyo Engineering Co. (NSKE; Tokyo, www.nske.co.jp). The demonstration unit, developed at the…

A fast way to recover CO2

A rapid pressure-swing-adsorption (rPSA) system to separate carbon dioxide from fluegas is being developed by W.R. Grace & Co. (Columbus, Md.; www.grace.com) and three partners under a $3 million grant from the U.S. Dept. of Energy (DOE; Washington, D.C.; www.energy.gov).…
