Bioenergy w CO2 removal and disposal
6
Principal methods for CO2 removal
7
Specific CO2 emissions of power/CHP plants with
CO2 removal (incl. compression to 100bar)
8
CO2 removal costs (incl. compression to 100bar)
around US 20-30 /t CO2 for transportation and
disposal

Summary removal technologies system
considerations
14
Is CO2 from biomass tradable?

• Ways to certify emission reduction credits
• reducing anthropogenic emissions by
  sources,orenhancing anthropogenic removals by
  sinks?

15
Implementing bioenergy w CO2 removal disposal

• CO2 disposal schemes are being developed by
  companies from the fossil-fuel sector. Will they
  welcome disposal of CO2 from biomass?
• Disposal of CO2 from biomass may require
  cooperation
• CO2 disposal projects are large-scale
• Pulp paper producers are increasing their focus
  on core competencies, and less resources are
  available for energy management
• Bioenergy producers are small and independent

16
Research and development
Integration of biomass energy and fossil-fuel
energy RDD is required

• Introduce biomass energy into CO2 removal and
  disposal RDD
• Large-scale biomass energy applications with CO2
  removal and disposal
• Identify opportunities for synergies and phasing
  in biomass in CO2 disposal schemesFor example
  through
• Co-firing coal and biomass w CO2 removal
• Introduction of biomass-based methane in natural
  gas networks
