A flexible, origami-based fuel cell
Until now, manufacturing polymer-electrolyte membrane fuel cells (PEMFCs) that are small, light and capable of mechanical movement has been challenging using conventional methods. PEMFCs are composed of end plates, bipolar plates, gaskets, membrane-electrode assemblies (MEAs) and other assembly parts, of…
A solvent-free process makes battery electrodes
Conventional processes for manufacturing battery electrodes use toxic solvents and require a lot of space and energy. In contrast, DRYtraec — a new dry-coating process developed by the Fraunhofer Institute for Material and Beam Technology (IWS; Dresden, Germany; www.iws.fraunhofer.de) —…
Chementator briefs
'New food' GEA AG (Düsseldorf, Germany; www.gea.com) has received a contract from Novozymes A/S (Copenhagen, Denmark; www.novozymes.com) for a turnkey fitting of a major new plant to produce plant-based proteins for the plant-based food industry. The high double-digit million-euro order…
High-pressure fermentation for optimizing CO2 utilization
Biological processes can be used for the conversion of greenhouse gases into added-value chemicals. With a new, unique high-pressure (up to 10 bars) fermenter, the Flemish Institute for Technology Research (VITO; Mol, Belgium; www.vito.be) is researching how these processes can…
Cost-efficient, on-purpose 1,5-PDO from bio-based starting material
Construction is underway on a demonstration plant for manufacturing 1,5-pentanediol (1,5-PDO) from bio-based furfural, a platform chemical that can be derived from plant-based hemicellulose sugars. The process under construction by the company Pyran Inc. (Madison, Wis.; www.pyranco.com) offers a lower-cost…
Fibrous catalyst support boosts yields and reduces coke buildup
A new fibrous catalyst-support material can enhance a wide range of industrial catalytic reactions, allowing higher yields and reduced coke buildup compared to pellet supports. Unifrax (Tonawanda, N.Y.; www.unifrax.com) leveraged its expertise in ceramic materials to develop the high-alumina fiber…
Solar-powered water extraction from atmospheric air
A first-of-its-kind pilot project in Abu Dhabi is integrating large-scale atmospheric water generation (AWG) with solar-thermal energy storage to enable carbon-free production of water. Led by partners AQUOVUM LLC (Dover, Del.; www.aqvglobal.com), Masdar Clean Energy (www.masdar.ae) and Khalifa University of…
Increasing recovery of metals from refractory mine tailings
EnviroGold Global Ltd. (Toronto, Ont., Canada; www.envirogoldglobal.com) has filed a patent application for a proprietary electrochemical process designed to achieve advanced metal recoveries from refractory ores with reduced capital expenditures (capex) compared to industry standard solutions. “The residual metals contained…
Vanadium recovery from steel slag scales up
A hydrometallurgical process for recovering vanadium from slag, a byproduct of steelmaking, has been significantly scaled up. Previously deployed at mini-pilot and bench scales, the process, developed by Neometals Ltd. (West Perth, Australia; www.neometals.com.au), has now been expanded by a…
An integrated thermochemical process makes advanced biofuels from biomass
Bionext and its partners — a consortium of six industrial companies — have successfully completed the test program on BioTfueL demonstration units, setting the stage for commercialization of the thermochemical process that makes low-carbon-footprint sustainable aviation fuel (SAF) and other…
