0:00:08i'm just clicking i am a system that's of energy policy here at the ohio
0:00:12state university where i have a joint appointment between the department of civil environmental and
0:00:17genetic engineering and the journal and public affairs and recently i've gotten into investigating innovative
0:00:25ways to use carbon dioxide two
0:00:28produced geothermal energy a few years ago some researchers at the university of minnesota came
0:00:35up with the idea to use you to carbon dioxide to produce due to thermal
0:00:41electricity
0:00:43by taking advantage of
0:00:46a concept called carbon dioxide capture storage
0:00:50where we
0:00:51put a large device and a big power plant or other facility that produces carbon
0:00:58dioxide and this device rather than allowing the carbon dioxide to be ended in the
0:01:02atmosphere is captured
0:01:04and then alternately injected underground where
0:01:07it is stored away or sequestered the atmosphere for a long period of time
0:01:13and the idea that these researchers had
0:01:15well as well if we can use that karma dioxide in places
0:01:20where the
0:01:22she walks from the earth is high enough we could actually circulate that common backside
0:01:28back up to the surface where we would withdraw he or extracted from this the
0:01:33carbon dioxide and used actually indeed a power plant
0:01:37as we pulled if you know the carbon dioxide would cool and we will injected
0:01:41back underground
0:01:42so and s that we would have a low carbon dioxide between the surface and
0:01:48subsurface
0:01:49more recently colleagues of mine and i have
0:01:54worked and
0:01:55a newer ways
0:01:56to use this carbon dioxide and combined with the geothermal heat
0:02:02the
0:02:03results of been quite remarkable actually
0:02:06one of the things that we've done as we taking advantage of
0:02:10ability
0:02:11two
0:02:12do directional drilling underground we're actually using this the directional drilling to create concentric rings
0:02:19all the wells
0:02:20where we moderate the amount of carbon dioxide that's being injected
0:02:24and two in order to create a
0:02:28pressure conditions under the under the ground where we can actually store energy in produced
0:02:34it when it's needed
0:02:35so not only are we circulating the carbon dioxide through the ground after each step
0:02:40bring it back up to the area and running through a power plant rows to
0:02:43able to store energy in these two
0:02:46concentric rings
0:02:48and this allows us to then
0:02:51alter or time shift
0:02:53a lecture see that's produced by other renewable sources such as wind and solar
0:02:58so their number of complementary is by using this view to first it enables us
0:03:03to deploy this carbon dioxide capture and storage approach to keep carbon dioxide from being
0:03:08admitted to the atmosphere
0:03:09it's like it allows us to use these renewable resources the geothermal heat
0:03:14to produce electricity and third and allows us to use the time index identity with
0:03:19our resources to level eyes fluctuations in wind and solar energy output
0:03:24as a consequence we expect we can make a pretty good dance
0:03:28in our in this instance you to the atmosphere and help to encourage the slow
0:03:34overturn of the energy system towards
0:03:36those the real actors technologies to rely more and we will be
