Abstract
Fossil
fuel electricity generation CO2 emissions vary considerably on any given day. Generation
profiles vary greatly between plants. Authors explain that understanding this
variability is critical for determining a carbon price. It is also important
for identifying if and how much CO2 a power plant will capture.
A CO2 emissions price, or tax, of between $85/tCO2 and $135/tCO2
will be required to incentivize a gas power plant to manage all its capturable
CO2. The range is due to differences in CO2 emissions profile. In addition,
carbon price is very sensitive to system-wide costs including the CO2 value for
enhanced oil recovery and, in particular, the costs for CO2 transport and
storage. Integrating fossil fuel power, particularly natural gas, into a
large-scale CO2 capture and storage system is a complex problem that will
require detailed research and modeling.
