"Five cornerstones to unlock the potential of flexible bioenergy";
Report for IEA Bioenergy TCP; Report No. 11/2021, 2021; 8 pages.

This paper is a summary of IEA Bioenergy Technology Collaboration Programme Task 44 to
encourage collaboration and knowledge sharing, to raise awareness for the important
potential of flexible bioenergy in sustainable energy system integration, and to explore issues
and solutions to fully realise this potential. The target audience of this paper are people
interested in energy policy, renewable energy, energy networks, as well as energy industry,
fuel producers, regulators, operators, scientists and informed stakeholders.
A large portfolio of innovative technologies is needed to achieve sustainable development
goals (SDGs) (Frankl 2020i). Achieving least-cost reliable and sustainable energy systems is a
global challenge. Renewable energy sources are key for all energy sectors to achieve climate
neutral energy supply till mid of century at the latest (IEA Net Zero by 2050 2021ii). Driven by
favourable policy environments, market opportunities and substantial cost reductions,
variable renewable energy (VRE) like wind and solar photo-voltaic (PV) are increasingly
important energy sources to expand energy access and enable electrification based on clean
energy. This essentially changes the structure and operation of the power systems, but also
influences the renewable energy provision for heat and transport sector.
Bioenergy, which was in the past mainly applied for heating and cooking, is now a key option
in fields where alternative renewable energy sources are difficult or costly to provide. Those
options for bioenergy are for example seen in the aviation sector, heavy duty transport, in
high temperature industry heat, but also in enhancing renewable energy supply systems for
residential heating during cold seasons or for electricity, especially if it comes to higher
provision from variable renewable energy (VRE) like wind and solar photo-voltaic (PV).
This paper describes the current role of flexible bioenergy in the energy system and identifies
potentials and bottlenecks, future pathways and the need for further work, analyses,
communication and collaboration
