Hollow silica particles (HSPs) are materials of interest for thermal insulation applications because of their very low thermal conductivity, but the particles pose health hazards and the powder is impractical to use, so scientists have been trying to incorporate HSPs…
Last month, Metso Outotec Corp. (Helsinki, Finland; www.mogroup.com) introduced NextGen Pelletizing — a visionary concept for the next generation of iron-ore pelletizing plants that strive to be carbon neutral and autonomous. According to the company, the combination of innovations —…
Polymer electrolyte membrane (PEM) electrolysis uses a membrane-electrode assembly (MEA) that integrates the electrolyte membrane and electrode (diagram). Large-scale hydrogen conversion of electricity requires a large number of MEAs, which is a drawback for scaleup, because the MEA relies on…
New materials, digitalization and simplified user interfaces reduce downtime and ensure safety in pressure-measurement applications Optimizing uptime and safety are among the two highest priorities for chemical processors, making reliability in pressure-measurement devices essential to ensuring that key processes are…
Magnesium metal is important for several emerging potential sustainability-related applications, including carbon capture, low-carbon cement and energy storage. These potential applications are driving efforts to efficiently produce magnesium hydroxide, the raw material for manufacturing Mg metal. It is possible to…
A new paper material developed at Northeastern University (Boston, Mass.; www.northeastern.edu) is capable of passive cooling, potentially reducing the energy load required for air conditioning in buildings. “The paper is made from fibers of a calcium-based material called hydroxyapatite. The…
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…
At Achema 2022 (Frankfurt am Main, Germany; August 22–26), a new compressor designed for hydrogen service was launched by Aerzen Machinenfabrik GmbH (Aerzen, Germany; www.aerzen.com). “We consider this solution to be the game changer in the market,” said Michael Leitsch,…
Plant Watch Gevo breaks ground on commercial-scale SAF facility in South Dakota September 16, 2022 — Gevo, Inc. (Englewood, Colo.; www.gevo.com) announced the groundbreaking in South Dakota of its first commercial-scale sustainable aviation fuel (SAF) facility, Net-Zero 1 (NZ1). This…
An expanding array of CO2-capture approaches are quickly developing for hard-to-abate industrial sectors. The key objective is to significantly lower the costs of traditional CO2-capture techniques, which are based on aqueous alkanolamine absorption and desorption Achieving climate mitigation objectives, such…
