Identification of locations for introducing Bio-CCS
Master(2015) Shota Kobayashi
In the recent years, Bio-CCS has drawn attention as a mitigation policy for climate change. Bio-CCS is a technique that separates and stores CO2 emitted by conversion of biomass into energy.
This study analyzes the best location for CO2 capture/storage area assuming that Bio-CCS will be introduced in western Japan. Simultaneously, the lowest cost for identified areas is calculated.
For example, the world in 2030 is assumed to be changed from a middle-level world, in terms of climate change, to a strict level.
In this case, this study can assess the locations and utilization rates introduced as capture/storage areas as shown in the left figures; the cost for identified areas also can be estimated.
On the other hand, different locations, utilization rates and costs are identified by changing input data such as cost for facilities, CO2 reduction target and so on.
Left hade figures:
a) Utilization rates for CO2 capture areas
b) Utilization rates for CO2 storage areas
This study can analyze the locations and the lowest cost for introducing Bio-CCS from various assumptions. Though, Bio-CCS hasn’t been popular.
Therefore, this study can contribute when we consider the way to mitigate climate change and the role of Bio-CCS in mitigation policies.
