A new type of steam-reforming system that produces — in a single step — purified, compressed hydrogen from methane has been developed by a team of scientists from CoorsTek Membrane Sciences AS (Oslo; www.coorstek.com), the University of Oslo (both Norway;…
A team from the National University of Singapore (www.nus.edu.sg) led by professor Boon Siang Yeo has developed a prototype device that uses artificial photosynthesis to produce ethylene using only sunlight, water and CO2, at room temperature and pressure. The team…
Perovskite solar cells have attracted much interest in the past few years as the next-generation solar cells capable of surpassing silicon cells’ efficiency. However, because the perovskite materials are easily decomposed in moist conditions, they must be properly encapsulated, which…
Scientists from ExxonMobil (Irving, Tex.; www.exxonmobil.com) and the Institute of Chemical Technology (ITQ; Valencia, Spain; http://itq.upv-csic.es) have discovered a new material that could significantly reduce the amount of energy and emissions associated with the production of ethylene. Depending on the…
Photocatalytic reduction of CO2 into a fuel is an attractive way to reduce CO2 emissions into the atmosphere, and there are many projects underway around the world to find ways of converting CO2 into chemicals, such as H2, CH4, ethanol,…
High-surface-area beads filled with microbes are being used to reduce biosolids in wastewater. In one case, Drylet LLC (San Francisco, Calif.; www.drylet.com) has developed engineered porous particles that provide large surface areas (the equivalent of 12 football fields of surface…
A biodiesel fuel blend known as B20 contains oils derived from waste coffee grounds, and will be used to power mass transit buses in London. The fuel is made through a partnership among bio-bean ltd. (London, U.K.; www.bio-bean.com), which has…
Foam dyeing, a new technology for dyeing cotton yarn that is being applied to denim production for the first time, eliminates the use of several chemicals and can reduce water use by up to 90% compared to traditional dyeing. The…
Landfill leachate and other challenging wastewaters incur rising treatment and disposal costs. Technology developed by Heartland Water Technology, Inc. (Hudson, Mass.; www.heartlandtech.com) can lower costs for treating wastewater by slashing wastewater volumes by 95% or more, using waste heat as…
H2SO4 Catalyst BASF SE (Ludwigshafen, Germany; www.basf.com) has introduced a new catalyst for making sulfuric acid. The cesium-based O4-115 Quattro catalyst has a unique geometrical shape — a combination of four strands — leading to a 30% greater catalytic surface…
