Technologies for Flexible Bioenergy (Updated)

Task 44 new report published

As the share of variable renewables like wind and solar increases, flexibility becomes a key requirement for stable and resilient energy systems. This report explores how sustainable bioenergy can provide flexibility to the energy system in multiple dimensions, including temporal, spatial and sectoral flexibility, as well as flexibility with respect to feedstock, operation, and end-products.

Bioenergy contributes to both short-term flexibility (e.g. balancing electricity grids, providing peak-load heat) and long-term flexibility (e.g. storing and transporting biomass-based energy carriers, enabling cross-sector use). The report presents core technologies that demonstrate how bioenergy can inherently or in combination with other energy sources enhance system controllability and stability.

A concise overview of these technical options is provided, with more detailed information and references available in the appendix.
