I mentioned SiGNa Chemistry last week regarding their recent Green Chemistry award from the Environmental Protection Agency (EPA).One particular interesting application for SiGNa’s technology is in fuel cells and you can read more about it in this article I’ve written for ICIS News:
US SiGNa targets green chemicals marketNEW YORK (ICIS News)–Advanced materials company SiGNa Chemistry plans to develop its green chemistry materials in fuel cells and pollution prevention, the company’s CEO said on Thursday.
“Our materials can destroy polychlorinated pollutants such as dioxins and polychlorinated biphenyls (PCBs) as well as chlorofluorocarbons (CFCs), which are difficult to break down and dispose of,” said Michael Lefenfeld, SiGNa’s CEO, in an interview with ICIS.
“SiGNa’s non-pyrophoric powders can destroy these toxins either in a batch or in a continuous-flow process by converting their halogenated atoms, such as bromine, chlorine and fluorine, into harmless molecules,” he said.
For fuel cells, SiGNa’s materials can produce under 10 weight percent hydrogen without a catalyst, just by adding water, according to Lefenfeld.
“SiGNa’s powder will be a great source of emergency, single-use fuel-cell power such as battery packs for soldiers,” Lefenfeld said.
“The material is not recyclable or regenerable so it’s good as a back-up power in general,” he said.
