Geo-spatial economic assessment of the potential development of bioenergy combined with direct air carbon capture (BEDAC) in the USA
Favero, A., Realff, M., Lucas, M., Giarrusso, A., & Lang, K. (2023). Geo-spatial economic assessment of the potential development of bioenergy combined with direct air carbon capture (BEDAC) in the USA. Environmental Science & Technology, 57(51), 21681-21690. https://doi.org/10.1021/acs.est.3c06975
This study presents a geo-spatial and economic framework to localize future bioenergy power plants combined with direct air capture (BEDAC). This framework is applied to two regions in the USA to assess the optimal use of forest biomass and in situ carbon sequestration under three specific short-term sequestration targets. Results show that there are many locations that have both the necessary biomass and geology required for storage. The Southeast has greater potential for forestry biomass due to both the rate of growth and forested areas, but the sequestration potential is mostly limited to a CO2 solution in saline aquifers. The Pacific Northwest has more sequestration potential than the Southeast given the location of managed forests and storage sites in carbonate mineralization in bedrock. The two combined regions have a total potential sequestration of 9.3 GtCO2 for the next 20 years that can be achieved under an implicit carbon value of $249/tCO2.
