![]() ![]() in Engineering with a minor in Mechanical Engineering from Lafayette College. Through these assessments she applies tools such as Life Cycle Analysis (LCA), techno-economic assessment (TEA), and energy system modeling. During her time at LLNL, Hannah has assessed several energy technologies and policies that focus on carbon capture, reducing life cycle emissions of carbon dioxide to the atmosphere, and those that produce negative emissions. ![]() Hannah assesses the cost and performance of technologies that reduce the environmental climate impacts of energy and materials production. Since starting at LLNL, Hannah has been involved in many diverse projects including the LLNL Flow Chart initiative, the Carbon Initiative, cyber security and more recently joining the Nuclear Enterprise Working Group. Hannah is an Energy Technology Analyst at the Lawrence Livermore National Laboratory (LLNL). His research is focused on the enhancement and acceleration of natural carbon sequestration pathways, and techno-economic modelling of the commercialization of these pathways. He previously spent time as a Technology-to-Market Summer Scholar for the Advanced Research Project Agency, and also as a delegate and policy consultant for the Consortium for Advanced Bioeconomy Leadership Education. Specific interests include integrating CO2 capture in existing and emerging bioprocesses, such as fermentation, anaerobic digestion, chemical pulping, and graphitization.Įthan Woods is a PhD student at North Carolina State University and a Graduate Research Assistant in the Biocarbon Utilization and Sequestration Lab. His lab takes an interdisciplinary and applied approach to identify low-risk, near-term opportunities to leverage the bioeconomy for carbon removal. Prior to his current appointment, he conducted research at the US Department of Energy and scaled up an advanced biofuel technology. Joe Sagues is an Assistant Professor in Biological & Agricultural Engineering at North Carolina State University and Principal Investigator of the Biocarbon Utilization & Sequestration Lab. ![]() Specific interests include bioenergy with carbon capture and sequestration, carbon storage in biopolymers, biochar, and harvested wood products, and economic valuation of non-permanent carbon storage using integrated assessment models. He previously collaborated with Lawrence Livermore National Lab to understand decarbonization options in the corn ethanol industry. He is an interdisciplinary scholar with a recent emphasis on life cycle and technoeconomic assessment of biomass carbon removal and storage (BiCRS). John Dees is a PhD Candidate at the Energy and Resources Group, University of California, Berkeley and Graduate researcher under Dr Dan Sanchez. Finally, we highlight the need to characterize both the magnitude and permanence of carbon drawdown as a means for policymakers and technology developers to deploy limited biomass resources to maximize mitigation benefits. We identify three engineering strategies for enhancing carbon drawdown: reducing biomass supply chain emissions, maximizing carbon stored in long-lived products, and extending the term of carbon storage. However, non-BECCS pathways achieve 34–64% of the drawdown magnitude relative to BECCS and retain 55–67% of their initial drawdown over 100 years (central estimate). We find that the BECCS pathway has the greatest magnitude and durability of CO 2 storage over all time horizons. We analyze the life cycle greenhouse gas emissions and disposition of sequestered carbon over 10 000 years for four bioproducts representative of each broader category: an advanced BECCS pathway, biopolyethylene, oriented strand board, and biochar soil amendment. There are numerous opportunities to incorporate carbon removal and management within the bioeconomy, but the majority of immediate carbon removal potential exists in four bioproducts: bioenergy, bioplastics, biochar, and wood products. This article provides a qualitative overview of prominent BiCRS technologies from which a set of the most promising technologies are assessed quantitively through life cycle assessment. The concept of BiCRS has the potential to enable a future where the climate mitigation value of biomass resources is more valuable than the energy value, due to the potential to remove and sequester large quantities atmospheric CO 2. Recently, attention has shifted further from a relatively narrow focus on BECCS to a broader focus on Biomass Carbon Removal and Storage (BiCRS). Amongst drawdown technologies, bioenergy with carbon capture and sequestration (BECCS) has received considerable attention in the climate mitigation literature. Stringent climate change mitigation scenarios rely on large-scale drawdown of carbon dioxide from the atmosphere.
