IEA Bioenergy Task 40: Deployment of biobased value chains (in the triennium 2016-2018 known as ‘Sustainable biomass markets and international bioenergy trade to support the biobased economy’), commonly abbreviated Task 40, was established under the International Energy Agency (IEA) Bioenergy Implementing Agreement in December 2003 with the aim of focusing on international bioenergy technology potential, barriers, and trade as well as its wider implications.

Bioeconomy Synergies Project
Progress & Prospect Report 2019-2021

This document explains scientific findings from the internal Task 40 project on Circular Bioeconomy, in particular with the following outputs:

  • Provide case studies of synergies between food/feed, material and energy uses of biomass
  • Create a first version of a resource flow database for modelling synergies in a Circular Bioeconomy
  • Derive insights for bioeconomy supply network modelling, policy recommendations and the strategic direction of the IEA Bioenergy Task40 including follow-up projects

Carbon accounting in Bio-CCUS supply chains – identifying key issues for science and policy

Task 40 leads the intertask project “Deployment of Bio-CCS/CCU Value Chains” and as a result this report was published in February 2022 as contribution of IEA Bioenergy Task 40/45.

Renewable gas ‐ deployment, markets and sustainable trade

The main objective of the project was to enable more deployment of renewable gases and to underpin their sustainability. It was carried out in collaboration with IEA Hydrogen, EC DG ENER and industrial partners, and was completed in March 2022.
