New project aims to scale up rapid carbon-capture process
A new project is exploring a unique large-scale carbon-capture facility in the U.S. Technology developer Svante, Inc. (Burnaby, B.C., Canada; www svanteinc.com), is working with LafargeHolcim, Oxy Low Carbon Ventures, LLC and Total S.A., to evaluate the construction of a…
Reduce the humidity and make some electricity on the side
Researchers at the Dept. of Materials Science and Engineering, National University of Singapore (www.nus.edu.sg), led by professor Swee Ching Tan, have combined a moisture-absorbent gel with light-active materials to develop a humidity “digester” that dries ambient air while generating energy.…
Japanese ‘clean coal’ demonstration project takes a step further
Construction has begun on the third step of a project to demonstrate the world’s first integrated coal-gasification fuel-cell (IGFC) combined cycle power plant with CO2 capture. The five-year, $73.3-million project is a collaboration of the New Energy and Industrial Technology…
Chementator Briefs
Sludge to fuel Bio-sludge is a byproduct of the wastewater treatment process at Stora Enso Oy’s (Helsinki, Finland; www.storaenso.com) Heinola fluting mill in Finland. In the past, the mill had been burning the bio-sludge at the power station for generating…
Bottom-up synthesis of new perovskite material for ammonia production
Perovskites are a class of synthetic materials that have a crystalline structure similar to that of the naturally occurring mineral calcium titanate. They have been the subject of many studies because they exhibit unique properties that can be tuned according…
Metals from nodules on seabed offer environmental advantages
Small-scale pilot testing has begun for a process that extracts nickel, manganese, cobalt and copper from nodules collected from the surface of the Pacific Ocean seafloor. Obtaining the metals from the seabed nodules has advantages over mining land-based ores because…
New material promises to enhance performance of gas-separation membranes
Harnessing its polymer technology and carbon-fiber expertise has enabled Toray Industries, Inc. (Tokyo, Japan; www.toray.com) to create a porous carbon fiber with uniformly continuous pores (diagram) — claimed to be a world’s first. Using this fiber as a support layer…
A Pt-free electrode promises to cut costs for fuel cells and metal-air batteries
Hiroya Abe and colleagues at Tohoku University (Sendai, www.tohoku.ac.jp) and Hokkaido University have developed a method to fabricate a highly active catalyst electrode for performing the oxygen reduction reaction (ORR) in fuel cells and metal-air batteries. Currently, such fuel cells…
Non-halogenated flame-retardant material
Dynamic Modifiers LLC (Atlanta, Ga.; www.dynamicmodifiers.com), a maker of custom polyolefin compounds, recently introduced PAL…VersaCHAR, a non-halogenated flame-retardant polymer designed to be molded over other materials. When exposed to flame, the formulation’s surface chars quickly, which prevents flame spread and…
Cascade reactions on ‘nanozymes’ make chemicals from CO2
An international team of researchers has developed metallic nanoparticles that imitate enzymes to convert carbon dioxide into ethanol and propanol, which are common raw materials for the chemical industry. The team includes professors Justin Gooding and Richard Tilley from the…
