I've seen several opportunities/companies that could do the half a gigaton and meet the other criterion really fast, but raising money is a grind:
* Advanotech.com - makes fully functionalized silicon nanoparticles at a fraction of the current cost. This automatically gives a performance enhancement to batteries that hits double digit percentiles.
I hope that whoever leads up this fund has deep chemistry competency to be able to fund things that will move the needle on gigatons of carbon emissions.
Bill Gates's statements on energy have been far more in line with the realities of minerals, carbon emissions, and lithospheric realities the statements of many other billionaires.

* http://www.powertechwater.com/ also does something pretty awesome by removing solids from brackish water.
