Bioenergy with Carbon Capture and Storage Approaches for Carbon Dioxide Removal and Reliable Sequestration: Proceedings of a Workshop -- in Brief (2018)Board on Atmospheric Sciences and Climate
Bioenergy with carbon capture and storage (BECCS) is a technology that integrates biomass conversion to heat, electricity, or liquid or gas fuels with carbon capture and sequestration. BECCS could provide a significant portion of the global energy supply if deployed to its theoretical maximum feasible amount. The future role of BECCS is a subject that divides researchers as estimates of potential future biomass supply vary widely due to differences in approaches used to consider factors such as population development, consumption patterns (e.g., diet), economic and technological development, climate change, and societal priorities concerning conservation versus production objectives. Nevertheless, many integrated assessment models use large-scale deployment of BECCS in scenarios that limit climate change to below 2 degrees celsius.
On October 23, 2017, the National Academies of Sciences, Engineering, and Medicine convened a third meeting in Irvine, California, to explore the state of knowledge and research needs related to the potential of BECCS as a CDR approach. Invited speakers gave an overview of biomass production pathways and capacities, implications of various feedstocks, advanced conversion technologies, and capture and storage strategies. Presenters at the workshop also discussed cross-cutting issues that include life cycle impacts of large-scale BECCS deployment, policies and incentives for the implementation of these approaches, and social acceptability barriers. The workshop was preceded by an introductory webinar on October 16, 2017, where invited speakers provided a primer on the prospects of BECCS for negative emissions capacity; the capacity for biomass to meet stationary generation and transportation fuel needs; and the status, challenges, and costs of implemented bioenergy and biofuels. This publication summarizes the presentations and discussions from both the webinar and workshop.
