Engineers at MIT (Cambridge, Mass.; www.mit.edu) are developing solar concentrators that have the potential to increase the electrical power output from solar cells by a factor of more than 40. Instead of actually focusing the light, as in systems being…
The production of hydrogen by water splitting promises to become less expensive through a solar-energy process being developed at Penn State University (University Park, Pa.; www.psu.edu). Like other photoelectrochemical methods, the process splits water into its two components, generating O2…
Among this year’s award winners of the U.S. Environmental Protection Agency’s (EPA; Washington, D.C.) Presidential Green Chemistry Challenge are: Battelle, SiGNa Chemistry, Inc., Nalco Co., Dow AgroSciences and Michigan State University. Battelle (Columbus, Ohio; www.battelle.org) received the Greener Synthetic Pathways…
Chisso Corp. (Tokyo, Japan; www.chisso.co.jp) has established a new joint-venture (JV) company to produce solar grade silicon using a new process that was first developed by Chisso and subsequently refined, jointly, by the three JV partners: Chisso (50% share), Nippon…
QuantumSphere, Inc. (Santa Ana, Calif.; www.qsinano.com) has commercialized electrodes coated with the firm’s Nano NiFe catalysts for making hydrogen in water electrolyzers. Available in production quantities, the electrodes effectively increase the surface area used in commercial electrolysis by about 1,000…
Time consuming and prone to error, microscopy — the manual counting of yeast cells with a hemocytometer — has long been the primary method for determining the progress of ethanol fermentation. However, a new joint development agreement between Fluid Imaging…
The global market for carbon-capture technologies was worth $88.7 billion in 2007, and is expected to increase to over $236.3 billion by 2012, according to a report published last month by BCC Research (Wellesley, Mass.; www.bccresearch.com). Postcombustion, the absorption of…
The high salt concentrations, extreme pH values and high temperatures required in biotechnological research on extremophiles and marine organisms cause corrosion in the stainless-steel components of common fermenters. To enable further process development in these areas, Bioengineering AG (Wald, Switzerland;…
Last month, Cargill (Minneapolis, Min.; www.cargill.com) broke ground in Chicago on a $22-million manufacturing plant for producing BiOH polyols. Scheduled for startup in November, the facility will be the first world-scale biobased polyols plant; since BiOH polyols were commercialized in…
Evonik Industries AG (Essen; www.evonik.com) and SolarWorld AG (Bonn, both Germany; www.solarworld.de) have officially opened their new solar silicon plant in Rheinfelden (Baden, Germany). As part of the joint venture Joint Solar Silicon (JSSI), the two companies are using an…
