One of the major hindrances in saltwater electrolysis for “green”-hydrogen production is the cost of materials to construct electrolyzer components that can withstand an extremely corrosive saltwater environment. Currently, titanium coated with platinum or gold is usually required for such…
Direct-air capture (DAC) of atmospheric carbon dioxide presents promise for helping to reach global-warming reduction goals. However, many DAC technologies are hindered by high costs and inefficiency. RepAir Carbon (Yokne-am Illit, Israel; www.repair-carbon.com) recently launched a field prototype of its…
Using concentrated solar thermal (CST) energy to supply industrial-heating requirements is a promising way to reduce the use of fossil fuels. This is the aim of Magaldi Green Energy (Rome, Italy; www.magaldigreenenergy.com), which developed its Solar Thermo Electric Magaldi (STEM)…
To decarbonize steel production and its high carbon dioxide emissions, Fraunhofer researchers, TS Elino GmbH (Dürren; www.elino.de) and Salzgitter AG (all Germany; www.salzgitter-ag.com) are working on converting an existing steel mill to climate-neutral production methods. The aim is to produce…
CO2 to CO SK Innovation Institute of Environmental Science & Technology, an R&D organization of SK Innovation Co. Ltd. (Seoul, South Korea; www.skinnovation.com), has successfully manufactured about 1 kg/d of CO using diatomic catalyst (DAC) technology, which selectively converts CO2…
Capturing natural gas from petroleum drilling wells is economically challenging, but would have positive environmental impacts because it would eliminate the need for flaring and could allow the hydrocarbons to be converted into useful chemicals. Now, research led by chemists…
In traditional beer brewing, the progress of the fermentation process is typically checked manually, by inserting a hydrometer (beer spindle) that measures the density, from which the extract content of the wort can be derived — a procedure that not…
Researchers at Eidgenössische Technische Hochschule Zürich (ETH Zurich; Switzerland; www.ethz.ch) and Nanyang Technological University Singapore (NTU; www.ntu.edu.sg) developed a process to utilize industrial chicken feathers for making proton-conductive membranes that can be used in fuel cells, protonic transistors and water-splitting…
A new ammonia-recovery plant has begun steady-state operation to demonstrate a patented process to upcycle the ammonia content from cattle manure into stabilized fertilizer ingredients. The Ammonia Recovery System (ARS) was developed by Bion Environmental Technologies, Inc. (Old Bethpage, N.Y.;…
A new plasma-based technology is being touted as a more sustainable method for textile finishing, including water-intensive dyeing and coating processes. The Ausora process, developed by Xefco Pty. Ltd. (Eveleigh, Australia; www.xefco.com), in partnership with the Recycling and Clean Energy…
