IEA Bioenergy, also known as the Technology Collaboration Programme (TCP) for a Programme of Research, Development and Demonstration on Bioenergy, functions within a Framework created by the International Energy Agency (IEA). Views, findings and publications of IEA Bioenergy do not necessarily represent the views or policies of the IEA Secretariat or of its individual Member countries.

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

DemandNet demand When 40% of

electricity demand covered by wind power in an example system

Note: net demand is also described as residual load

www.ieabioenergy.com

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%,

15%...) Emission performance Efficiency, steam properties

Increasing the flexibility of biomass boilers

www.ieabioenergy.com

1. Co-generation with flexible output ratios Heat + Power Fuels + Power Fuels + Heat + Power

1. Only chemical energy source in a non-fossil energy system

1. Naturally easily storable as Solid Liquid
