and sna senator shaheen was par that for large corbin capture and storage. my question would be, what is the pathway and what can the department give us in terms of information as to what your scientists believe is the way to move to commercially viable demonstration projects? >> sure. first, the carbon capture technologies that are being tested today, and i'll divide them into two categories. this is after combustion, you capture the carbon. there are mea-type technology, chilled technologies. those are being tested and since they're by and large in the commercial sector, we feel that we would like to develop less expensive means, because if you make -- if you put in an estimate how much would increase the electricity bills we think this would not -- would not spur not only the united states but china and india to use these technologies. woe like to improve them. there are potential ways to improve them. one of those ways to put very large high surface areas. we're investing a lot of research to decrease the size of these capture stacks. totally different w
