Cybersecurity Threats Prompt Proactive Approach
An evolving threat landscape for plant security is attracting more attention to the development of operational technology (OT)-specific cybersecurity programs, underlining the importance of collaboration and blurring the line between cyber- and physical security Cybersecurity threats against critical infrastructure sites,…
First commercial DAC facility in the U.S. captures CO2 for concrete
In November 2023, Heirloom Carbon Technologies (Tracy, Calif.; www.heirloomcarbon.com) unveiled the United States’ first commercial direct air capture (DAC) facility, which can capture up to 1,000 ton/yr of CO2. The process first uses renewable energy to remove CO2 from limestone…
This new stainless steel is ultra-resistant to corrosion
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 molten-salt electroplating cuts battery costs
The extremely high material purity demanded for conventional lithium-ion battery manufacturing creates considerable costs for transporting and refining lithium and other raw materials. Through the development of a single-step electroplating process that uses lower-purity raw materials and a nanostructured-foam electrode…
A continuous electrochemical process for direct-air CO2 removal
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…
Chementator Briefs
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…
Converting a steel mill to climate-neutral steel production
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…
Water-cooled servomotors for extreme dynamic requirements
The AM8300 servomotors expand this company’s portfolio to include a modular motor series with integrated water cooling (photo). Due to the efficient cooling, an extremely high power density is achieved, so that a rated power of up to 40 kW…
Fouling-immune membrane available for brackish-water RO applications
In November 2023, the first commercial test was initiated for a novel, fouling-immune membrane for brackish-water reverse osmosis (BWRO) applications through an early-access program. Membrane developer ZwitterCo (Woburn, Mass.; www.zwitterco.com) says its membrane is fouling-immune in cases where fouling of…
Focus on Performance Materials
Remove PFAS from water with this ion-exchange resin MonoPlus TP 109 (photo) is a new macroporous anion-exchange resin for the selective removal of contaminants, such as per- and polyfluoroalkyl substances (PFAS) from water. Lewatit MonoPlus TP 109 is especially suitable…
