Global and regional potential for bioelectricity with carbon capture and storage

Among technological options to mitigate greenhouse gas (GHG) emissions, biomass energy with carbon capture and storage technology (BECCS) is gaining increasing attention. This alternative offers a unique opportunity for a net removal of atmospheric CO2 while fulfilling energy needs. Empirical studies using bottom-up energy models show that BECCS has an important role to play in the future energy mix. Most of these studies focus on global BECCS potential, whereas it is of interest to understand where this mitigation option will be deployed. This key issue will strongly depend on regions' biomass resources and possession of storage sites. The aim of this study is to assess the global and regional potential of BECCS up to 2050 in power generation. This analysis is conducted using the multiregional TIAM-FR optimization model. The climate policy scenarios investigated lead to a considerable expansion of renewable energy and CCS and BECCS technologies in the power sector. CCS from fossil fuel is mainly deployed in fast developing countries (India and China) and BECCS is highly distributed in developing countries, even though biomass resources are widely available in all regions. - Highlights: ► We assess the global and regional potential of BECCS in the power sector up to 2050. ► This analysis is conducted with the multiregional TIAM-FR optimization model. ► BECCS plays an important role in the electricity mix to achieve ambitious targets.
