Research has shown extreme weather like heat waves, are closely connected to human-caused global temperature increases.

7. what is BECCS Introduction to BECCS A system,a combination
Bio-energy with carbon capture and storage (BECCS) is a future greenhouse gas mitigation technology which produces negative carbon dioxide emissions by combining bio-energy (energy from biomass) use with geologic carbon capture and storage.

8. Bio-mass energy Introduction to BECCS
Biomass is an industry term for getting energy by burning wood, and other organic matter.
CO2 emission:
>= 1.25
Rnewable

9. CCS:carbon capture and storage
Introduction to BECCS
CCS:carbon capture and storage
Carbon capture and storage (CCS)is the process of capturing waste carbon dioxide (CO2) from large point sources, such as fossil fuel power plants,and transporting it to a storage site.
Capture efficiency >80%.
The stage for CCS: capture,separation,transport,storage,leakage and monitoring,and life cycle analysis.

10. carbon capture Introduction to BECCS
Main shortage:CCS full chain technologies not proven at full commercial scale.
Contribute to around 70–80% of the total cost of a full CCS system.
There are three main CO2 capture systems:
post-combustion
pre-combustion
oxyfuel combustion

11. carbon capture Introduction to BECCS post-combustion:
This process removes CO2 from the flue gas after combustion has taken place.
Cost of electricity would increase:
·32% in gas plants
·65% in coal-fired plants

12. carbon capture Introduction to BECCS pre-combustion:
In this process, the fuel (normally coal or natural gas) is pre-treated before combustion. and is mainly free from other pollutant gases
Efficiency loss：7%

13. carbon capture Introduction to BECCS oxyfuel combustion:
Use oxygen instead of air for combustion.
Contain high concentration of CO2 (80–98% depending on fuel used ).

14. carbon capture Introduction to BECCS
Pre-combustion:coal-gasification plants
Post-combustion and oxyfuel combustion: both coal and gas fired plants
(7%extra energy consume)
Moreover, the post-combustion CO2 capture is normally the least efficient option, with an energy penalty of about 8% and 6% for the coal-fired and gas-fired plants, respectively .

15. storage Introduction to BECCS Deep ocean storage——a feasible option
Geological storage:CO2 can be stored directly into geological formations
unmineable coal beds
saline aquifers
depleted (or nearly depleted) oil and gas reservoirs

16. storage Introduction to BECCS Depleted oil and gas reservoirs(EOR):
CO2 can be injected into depleted (or nearly depleted) oil/gas reservoirs to increase their pressure and provide the driving force to extract residual oil and gases, while the injected CO2 remains stored there permanently.
economical incentive
Recovery rates can be raised by about 30%~60%.

17. utilization of CO2 Introduction to BECCS
CO2 can also be used in other areas such as food beverages, refrigerants and fire extinguishing gases.

18. 2% utilization of CO2 Introduction to BECCS 700 Mt/year potential
forecasts predict chemical utilization
Current CO2 utilization
far greater than the combined potential of nuclear, wind and cellulosic biofuel technologies(data from 2014)

21. challenges Analysis of BECCS
The sustainability of BECCS relies heavily on intelligent management of the supply chain.
Choices made throughout the supply chain including:
transport
fossil energy required
land use
...

23. Possible solutions Analysis of BECCS
measuring and limiting the impacts of direct and indirect land use changes
using carbon neutral power and organic fertilizers
prioritizing sea and rail over road transport
increasing the use of carbon negative fuels
......

24. Prospect A reliable option under the right conditions
Fundamental to achieving the 1.5 °C goal as articulated by the Paris COP agreement.
A burden on ecnomics?
