Commercial debut for a low-cost stationary energy-storage system

A novel battery chemistry that uses a water-based electrolyte has allowed developer Aquion Energy Inc. (Pittsburgh, Pa.; www.aquionenergy.com) to achieve a low-cost and safe battery with long cycle life for stationary energy-storage applications. The Aquion battery technology, now entering its…

In-situ chemical remediation of soil and groundwater

Geo-Cleanse International, Inc. (Mata- wan, N.J.; www.geo-cleanse.com) has developed a new method for ridding soil and groundwater of chloromethanes, Freon and other difficult-to-treat contaminants without the need for digging and offsite soil treatment. The Geo-Cleanse process was inspired by research…

New ceramic membranes for oxygen separation

Researchers from Curtin University’s Fuels and Energy Technology Institute (Perth, Western Australia; www.curtin.edu.au), led by professors Gordon Parkinson and Chun-Zhu Li, have won the Mitsubishi Corp. Western Australia Innovator of the Year award for creating a new membrane that speeds…

Recovering and purifying byproduct and waste ethylene glycol

GlyEco Inc. (Phoenix, Ariz.; www.glyeco.com) has developed a process for recovering and purifying ethylene glycol from a number of industrial byproduct and waste streams so that it meets an ASTM International (West Conshohocken, Pa.; www.astm.org; formerly American Society for Testing…

Global Air-Pollution Regulations: Variation is the Norm

The chemical process industries (CPI) are, by their very nature, global in scope. While chemical process operators share many common aspects (in terms of the use of chemical engineering unit operations), the location of their operation brings about different requirements…
