Flow batteries have been widely deployed in large-scale energy-storage applications in recent years, but the low energy density and high cost of the incumbent vanadium electrolyte limit the long-term return on investment of such systems. A new organic redox flow-battery…
The PEM (proton exchange membrane) electrolysis process, which is particularly suitable for producing green hydrogen when the supply of electricity from wind power and photovoltaic systems fluctuates, is still very expensive compared to production using fossil fuels. Sustainability is also…
Inpex Corp. (Tokyo) and Osaka Gas Co., Ltd. commenced demonstration operations of a methanation test facility for a joint technology development project aimed at the practical implementation of a CO2 methanation system to achieve carbon neutrality for city gas. This…
MAIRE S.p.A. (Milan) announced that NEXTCHEM, through its subsidiary CONSER, a technology licensor for high-value chemical derivatives and biodegradable plastics, is reinforcing its portfolio with the introduction of the new NX CONSER PolyFlexTM technology to produce polytetramethylene ether glycol (PTMEG),…
SUEZ and PYREG, a global leader in organic waste pyrolysis solutions, are pleased to announce the deployment of Pyrolis® S2B, an innovative integrated solution for pyrocarbonization. This cutting-edge technology converts sewage sludge into biochar, offering a sustainable carbon sequestration solution…
As green hydrogen emerges as a key next-generation clean energy source, securing technologies that enable its stable and cost-effective production has become a critical challenge. However, conventional water electrolysis technologies face limitations in large-scale deployment due to high system costs…
In late December 2025, a system that uses electric fields — rather than mechanical means — to generate nanometer-sized gas bubbles entered operation at a commercial site in Saudi Arabia. The nanobubble-generating technology was developed by the startup company AquaB…
Post-consumer absorbent hygiene products (AHPs), such as infant diapers, feminine hygiene products and adult incontinence products, present unique challenges for recycling, because they contain compound materials like superabsorbent polymers and non-woven fabrics, as well as bio-hazardous waste, which are difficult…
The search for a new ammonia-synthesis method has now driven research and development work underground, literally. Addis Energy (Somerville, Mass.; www.addisenergy.com) is launching a subsurface synthesis technology that takes advantage of geologic chemistry to produce ammonia. “Addis Energy’s process uses…
Electrochemical water-treatment technologies facilitate the adsorption of ions, effectively removing contaminants such as calcium, magnesium, bromine and more. Such processes, however, are often hampered by the high costs associated with electrode regeneration and the use of ion-exchange membranes. A new…
