Two milestones for industrial solar-thermal production of fuels

In August, Synhelion S.A. (Lugano, Switzerland; www.synhelion.com) became the first company in the world to produce synthesis gas (syngas) on an industrial scale using only solar heat as an energy source. The milestone occurred on the multifocus solar tower of…

Rare-earth recovery from magnet scrap is being scaled up

Rare-earth materials are a crucial part of high-performance magnets in many electronic devices. Right now, only about 5% of these magnets are recycled, but tapping into end-of-life electronics is a promising and more sustainable source for rare-earth materials, the vast…

Extracting pressurized hydrogen from ammonia, methane and biogas

Proton ceramic cells that couple endothermic steam reforming with heat from electrochemical gas separation and compression have been scaled up. These cells, developed by CoorsTek Membrane Sciences AS (Oslo; www.coorstek.com), the University of Oslo (both Norway; www.uio.no) and the Institute…

Silicate-rock-based material can replace flyash in cement, lowering costs and CO2

Flyash, a waste byproduct from coal burning, has been used effectively as a supplementary cementitious material (SCM) in Portland cement to displace a portion of the cement and lower the CO2 emissions associated with cement making. But because coal burning…

A new electrolyte supercharges sodium-ion batteries

Sodium-ion batteries have many advantages over lithium-ion batteries due to sodium’s abundance and low cost. However, there are several performance challenges to overcome with sodium-ion batteries because there is typically a tradeoff between energy density and lifecycle. Now, a research…

A step closer to transition-metal catalysis with aluminum

Chemists from the Institute of Inorganic and Analytical Chemistry at the University of Freiburg (Germany; uni-freiburg.de) have synthesized a cationic, low-valence aluminum complex salt. “So far, there has been only one example of a cationic, low-valent aluminum compound, but it…

This particle sensor exploits quantum effects for real-time process optimization

Last month at Achema 2022 (August 22–26; Frankfurt am Main, Germany), Q.ANT GmbH (Stuttgart, Germany; www.qant.de) introduced what is said to be the world’s first industrial-grade quantum sensor (photo) for particle analysis. By the use of super-fast software, electronics and…
