Powder could help cut CO2 emissions
Scientists at the University of Waterloo have created a powder that can capture CO2 from factories and power plants.
The powder, created in the lab of Zhongwei Chen, a chemical engineering professor at Waterloo, can filter and remove CO2 at facilities powered by fossil fuels before it is released into the atmosphere and is twice as efficient as conventional methods.
Chen said the new process to manipulate the size and concentration of pores could also be used to produce optimized carbon powders for applications including water filtration and energy storage, the other main strand of research in his lab.

Of course it is only in the lab right now. I'll get excited if it can be scaled up to a full-sized operating plant, but it's a step in the right direction.
