Metso (Helsinki, Finland; www.metso.com) is supplying a 140-MWth biogasification plant to Vaskiluodon Voima Oy in Vaasa, Finland. When it starts up in December 2012, the €40-million gasification plant, which will be located next to the existing 565-MW coal-fired power plant, will convert biomass (mainly forest residues) into a so-called biogas that can be combusted with coal. The gasification facility...

Scaleup is set for two technologies that facilitate the capture of carbon dioxide from fluegas by substituting oxygen for combustion air. Oxycombustion, as it is called, results in a much smaller fluegas stream, containing up to 90% CO2; part of that is recycled to dilute the O2 and control the combustion temperature. The O2 is entrained in the CO2 stream for injection into the furnace. The companies...

A system that utilizes existing biological wastewater-treatment facilities for destruction of biodegradable volatile organic compounds (VOCs) and other organic hazardous air pollutants (HAPs) has been demonstrated at three U.S. petroleum-refining and chemical facilities, and the developer has plans to extend the U.S. patent-pending treatment approach to eight additional facilities in coming months. Environ...

Mitsubishi Heavy Industries Ltd. (MHI; Tokyo, www.mhi.co.jp) says it has established technology to produce bioethanol for automobile use by using soft-cellulose, such as wheat straw and rice straw, as raw materials. MHI estimates the fuel cost for a full-scale production plant — accounting for the costs of feed material and its collection and transportation, as well as bioethanol production costs...

Spider silk has many unique properties that make it suitable for applications such as coatings and medical products. As a protein, the silk is remarkably stable and is only destroyed physically or digested and recycled by the spider. However, an industrially viable synthetic route to spider silk has eluded researchers over the last 25 years, says Axel Leimer, managing director at AMSilk GmbH...

Ammonia borane’s (AB) capacity to contain and easily release large amounts of hydrogen has made it an attractive candidate to store the gas for onboard fuel-cell powered vehicles. A major technological hurdle that remains is how to reintroduce hydrogen to spent AB in an energy-efficient way. Now, a team comprised of researchers from Los Alamos National Laboratory (Los Alamos, N.M.; www.lanl.gov) and...
