New Publication – Roles of bioenergy in energy system pathways towards a “well-below-2-degrees-Celsius (WB2)” world
Report of a workshop held on 25 November 2019 in Berlin, and synthesis of presented studies
Under the IEA Bioenergy Inter-task project ‘The Role of Bioenergy in a WB2/SDG world’, a workshop was held in Berlin, on 25 November 2019. The objective of the workshop was to examine, synthesize and disseminate information from recent studies that investigate how bioenergy and associated technologies may contribute to achieving the reductions in greenhouse gas (GHG) emissions that are needed to meet the WB2 target. The report summarises the workshop contributions and discussions, assesses the role of bioenergy in WB2 strategies, identifies the current state of knowledge as well as gaps in knowledge that need to be addressed.
- Many scenarios that limit global warming to well below 2°C (WB2 world) include a significant and increasing contribution of biomass-based energy supply (bioenergy), often in combination with carbon capture and storage (CCS).
- Achieving the level of bioenergy and BECCS deployment found in many global WB2 scenarios will require a large increase in the biomass supply for energy and also establishment of CCS infrastructure to enable BECCS.
- The attractiveness of different bioenergy options differs between countries (e.g., related to biophysical conditions or geological CO2 storage capacity) and bioenergy strategies should not be prescribed at global/continental level, but rather developed within each country, reflecting the local context.
- Decisions concerning development of biomass resources and bioenergy systems are determined by the global as well as national and regional context. Therefore, analyses using models with different geographic scope and spatial resolution, ranging from global IAMs to more fine grained models are needed.
- As BECCS and other CDR (carbon dioxide removal) options commonly play important roles in WB2 pathways, it is warranted to intensify investigation and implementation of CDR in the near term.
- Integrated land use planning, applied at the landscape scale, can identify options for deployment of bioenergy and BECCS in ways that support achievement of multiple SDGs.
- Governance is critical to avoid or mitigate adverse side-effects and to promote synergies among important objectives, not the least associated with biomass supply systems.
