Task 44Flexible bioenergy and system integration
Overview on the role of bioenergy in the system integration of
variable renewables

There are 42 currently active Technology Collaboration Programmes, one of which is “IEA Bioenergy”
“IEA Bioenergy” is set up in 1978 by the IEA
Aim: is to improve cooperation and information exchange between national bioenergy R&D and deployment
work of IEA Bioenergy is structured in a number of Tasks (14 ongoing tasks and 33 completed tasks)
Task 44: Flexible Bioenergy and System Integration
IEA Technology Collaboration

DemandNet demand When 40% of
electricity demand covered by wind power in an example system
Note: net demand is also described as residual load

1. Faster cold start up Thermal loads on refractories and
pressure vessel Heat transfer to bed mass
2. Increased speed of load change
3. Wider operational range Lower minimum load (30%, 20%,
