Meeting our Energy Challenge
“Fossil fuels will remain the dominant source of energy worldwide, meeting 83% of the increase in energy demands”
Why is this?

Transforming CO2; Two main approaches
1. Use high chemical-energy starting materials
2. Supply high physical-energy;
heat, light, electricity, solar

Transforming CO2
The Top 10 emerging technologies for 2012
6. Utilization of carbon dioxide as a resourceCarbon is at the heart of all life on earth. Yet, managing carbon dioxide releases is one of the greatest social, political and economic challenges of our time. An emerging innovative approach to carbon dioxide management involves transforming it from a liability to a resource. Novel catalysts, based on nanostructured materials, can potentially transform carbon dioxide to high value hydrocarbons and other carbon-containing molecules, which could be used as new building blocks for the chemical industry as cleaner and more sustainable alternatives to petrochemicals.
