Challenges and Opportunities for Bioenergy in Europe: National Deployment, Policy Support, and Possible Future Roles

TL;DR

This paper reviews Europe's bioenergy landscape, highlighting challenges in supply security, inconsistent sustainability definitions, and competing demand uses, while proposing opportunities for better policy and research strategies to enhance future bioenergy roles.

Contribution

It identifies key challenges and opportunities in European bioenergy deployment, emphasizing the need for harmonized sustainability definitions and strategic use of bioenergy resources.

Findings

Supply security is challenged by import dependency and high consumption in some countries.

Inconsistent sustainability definitions hinder policy and modelling alignment.

Sector-coupled energy system models can guide optimal bioenergy use.

Abstract

Bioenergy is currently a major renewable energy source in Europe but faces an unclear future because of conflicting modelling results and the lack of long-term policy. This paper identifies three challenges and potential opportunities by reviewing bioenergy historical national deployment, current policy support, and possible future roles in Europe. The first challenge is on the supply side. Analysing the supply-consumption dynamics and import dependency of EU bioenergy, we find that the security of bioenergy supply is challenging for liquid biofuels and those countries with the highest per-capita bioenergy consumption in Europe. Second, the definition of sustainable bioenergy in modelling studies is sometimes inconsistent with how EU policies label it. Third, on the demand side, there are unique but competing uses for bioenergy without a clear long-term strategy in Europe. We conclude with three opportunities to tackle these challenges for future research. First, utilising the untapped bioenergy potential with low environmental impacts could improve supply security. A clear and harmonised definition of sustainable bioenergy could better convey modelling results to policymaking. Finally, understanding where best to use limited sustainable bioenergy supply through sector-coupled energy system models can provide direction for a clearer EU bioenergy strategy towards 2050.
