Renewable energy: breakthrough in chemical storage technology

Researchers at the University of Calgary have made a breakthrough in cheap and efficient catalysts for converting electricity into chemical storage through electrolysis. This could have a major impact in efficient use and regulation of power from renewable energy sources like wind farms and large scale solar energy power stations.

"This breakthrough offers a relatively cheaper method of storing and reusing electricity produced by wind turbines and solar panels," says Curtis Berlinguette, one of the study authors and associate professor of chemistry and Canada Research Chair in Energy Conversion.

Curtis Berlinguette and Simon Trudel from the University of Calgary Chemistry Department turned their attention to simpler and cheaper catalyst electrodes. They conducted laboratory tests using abundant metal compounds or oxides (including iron oxide or 'rust') to create mixed metal oxide catalysts having a disordered or amorphous, structure. The new catalysts they devised perform as well or better than expensive catalysts now on the market, yet theirs cost 1,000 times less.

Award for groundbreaking research in capturing Carbon Dioxide

A University of Sydney researcher has received an award for ground breaking work into capturing carbon emissions - research important to mitigating climate change by reducing atmospheric carbon pollution. Dr Deanna D'Alessandro, a post-doctoral fellow based in the School of Chemistry at Sydney University, was awarded a L'Oréal Australia For Women in Science Fellowship for her research on ways to capture and release carbon dioxide, hydrogen and other gases using molecular sponges.

Atmospheric CO2 is currently at 390 ppm (parts per million) and increasing. At our current business as usual rate of carbon pollution we should pass 400 ppm within 10 years. Research published in 2010 estimates that the CO2 level that will lead to collapse of the Greenland ice sheet is between 400 to 560 parts per million (ppm).
