1/Why?
The global energy demand is growing and so are the associated emissions.
In order to meet goals of Paris agreement, cutting greenhouse gas emissions (GHG) are needed.
Current CO2 concentration in atmosphere: 410 ppm
Target to meet 1.5 deg rise: 350 ppm

2/Carbon Capture
Adopting low carbon and renewable sources of energy along cannot help reach target emissions .
Carbon (CO2) capture at-scale is a bridge as the energy mix shifts.
* CO2 can removed from flue / burnt gases
* Pulling from ambient air, direct air capture

3/ CCS vs. CCUS
Carbon capture and sequestration (CCS): Remove CO2 and bury it underground in saline aquifers.
Problem: There is no economic value
$$ by Carbon capture utilization and storage (CCUS): Inject CO2 for enhanced oil recovery or convert CO2 to useful products

4/ Utilization: EOR
The only current carbon sequestration industry at scale and leaves CO2 permanently buried.
Hang on...to reduce emissions, we inject CO2 to get more fossil fuels?
Need to think in terms of net-carbon impact.
Production with and without carbon capture.

6/Costs and recent projects
Almost all projects have received government support.
Projects are capital intensive and as NRG energy found out difficult to operate.

7/ Policy support
In the US, the primary policy support for CCS is the 45Q federal tax credit:
* $35/ton for CO2 sequestered by EOR
* $35/ton for other beneficial uses of CO2
* $50/ton for CO2 sequestered outside of EOR.

8/Bottom line
Carbon capture projects are in million tons whereas the target is in Gigatons.
Long way to go.
Policy will have a big impact on adoption.
CCUS is another arrow in the decarbonization quiver.
