Fuel-cell solution lowers operating costs using nanostructured catalysts
The two main barriers to widespread use of fuel cells have been securing a reliable source of hydrogen that avoids CO2 emissions, and cost — they have traditionally depended on expensive platinum and palladium catalyst materials. GenCell Energy Ltd. (Petach…
Advanced water electrolysis launched
Last month, thyssenkrupp Industrial Solutions AG (Dortmund, Germany; www.thyssenkrupp-industrial-solutions.com) launched industrial-scale water electrolysis systems that make large-scale hydrogen production from renewable electricity economically attractive. The advanced water electrolyzer (diagram) features a well-proven cell design paired with an especially large (2.7…
The commercial launch of 3-D-printed membranes
Last month, Nano Sun, a water technology start-up founded by a scientist from Nanyang Technological University (NTU; Singapore; www.ntu.edu.sg) launched a 3-D-printing facility to manufacture a new type of water-treatment membrane. Unlike conventional membrane-manufacturing processes, which use acids to make…
An inexpensive, renewable aerogel shows promise for handling oil spills
Many methods have been developed to remove spilled oil and organic pollutants from water, but they all entail shortcomings, such as low absorption ability and poor buoyancy. Now, a team from the School of Light Industry and Chemical Engineering, Dalian…
Testing the limits of cryogenic distillation
CSIRO (Perth, Australia; www.csiro.au) and the University of Western Australia (www.uwa.edu.au) have developed a first-of-its-kind pilot plant for high-pressure cryogenic distillation processes. “Although cryogenic distillation is practiced in industry and there are some models that can be applied to cryogenic…
Extracting lithium from waste brine without ponds
The growing demand for lithium-ion batteries (LIBs) has created incentives to improve processes for extracting lithium from brine. Current Li-extraction processes involve pumping brine from underground into shallow pools for evaporation and concentration. But the traditional method has several significant…
More scalable method for membrane separations
Membranes present a lower-energy alternative to distillation for the separation of hydrocarbons, but these processes are often limited by prohibitively expensive materials or intricate fabrication steps. Now, a team of researchers from Texas A&M University (TAMU; College Station, Tex.; www.tamu.edu)…
The first commercial power-to-liquids plant planned
Nordic Blue Crude A/S (NBC; Porsgrunn, Norway; www.nordicbluecrude.no) intends to build the first power-to-liquids (PtL) plant in the Norwegian industrial park of Heroya, located 140 km southeast of Oslo. Although the date for the startup has not yet been released,…
Fast-pyrolysis process recovers valuable materials from tires
Each year, more than 1 billion automobile tires are replaced worldwide. Together, the used tires contain 4.4 million metric tons of valuable products, such as carbon black, metals, fuels and chemicals. In an effort to recover these materials, the University…
Making amine-based CO2 adsorbents more stable
Amine-containing solids have been investigated as promising adsorbents for CO2 capture, but existing amine-containing adsorbents degrade by oxidation, making them unreliable for repeated CO2 adsorption-desorption cycles over a long period. The low stability requires the continuous addition of fresh adsorbents,…
