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…
For the first time, an organic compound has been synthesized from water, carbon dioxide and sunlight — without any other external energy or reagents. The achievement, which was demonstrated by researchers at Toyota Central Research and Development Laboratories, Inc. (Toyota…
A facility that produces high-purity lithium carbonate for use in the growing market for electrolytes in electric-vehicle batteries has begun commercial operations in Imperial Valley, Calif. The 500-ton/yr plant, operated by Simbol Materials (Pleasanton, Calif.; www.simbolmaterials.com), is the only producer…
Impending standards requiring that cellulosic ethanol be used in gasoline blending have focused attention on building a capacity for bioethanol from non-food sources. In a development that may begin to meet that need, a plant employing a unique method for…
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…
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 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).…
A huge market for lithium ion batteries is expected to develop as car makers move toward electric vehicles. However, improvements in the batteries’ energy and power density are needed. It is also desirable to replace the common, high-cost lithium cobalt…
Renewable jet fuel Houston-based bioenergy company Terrabon Inc. (www.terrabon.com) has been awarded a $9.6-million, 18-month contract from Logos Technologies (Arlington, Va.; www.logos-technologies) to produce 6,000 L of renewable jet fuel for the Defense Advanced Research Products Agency (DARPA; Arlington,…
An underground coal-to-liquids (UCTL) technology is undergoing pilot testing at Oak Park, near Melbourne Australia, where a metric ton of brown coal is expected to yield about one barrel of oil suitable for use as refinery feedstock on an oil-parity…
