As the world’s largest emitter of greenhouse gasses (GHGs), China plays a central role
in the suite of options for climate change mitigation. To analyze the importance of
biomass and carbon capture and storage (CCS) availability in China, varying levels of
these parameters are created and then global climate scenarios are simulated using TIAM
(TIMES Integrated Assessment Model). TIAM is a 16-region global energy system
optimization model that includes a climate module that calculates the global
concentrations of GHGs in the atmosphere.
We analyze the potential for using biomass, CCS, and bioenergy CCS (BECCS) in China
under the constraint of meeting a climate stabilization target such that dangerous climate
change (as defined by the Copenhagen Accord) is avoided. When considering
hypothetical scenarios where GHG emissions are constrained, China consumes all
available domestic biomass as a relatively inexpensive fuel source. However, while
BECCS does have a small role to play, in general it is cheaper to use biomass for the
transportation sector and CCS with fossil fuel in order to meet both the energy demand
and emissions reduction goals in the cheapest way possible.
Therefore, we find that while both utilization of biomass and CCS are essential options
for reducing emissions in China, BECCS is not the most cost effective option in China.
CCS is nevertheless an important option for China; in the climate mitigation scenarios
modeled, by 2050, China is projected to employ CCS on at least 70% of fossil energy
electricity generation. When CCS is excluded, the cost of mitigation is more than
doubled compared to the scenarios where CCS is included as a mitigation option.
