Bury, Burn or Both: A Two-for-One Deal on Biomass Carbon and Energy

  journal={Climatic Change},
Once harvested, there are three general ways in which biomass may be used to manage carbon. It may be used as an almost CO2-neutral substitute for fossil fuels, it may be sequestered away from the atmosphere by burial, or finally, it may be used as a substitute for fossil fuels with capture and sequestration of the resulting CO2 (Keith, 2001b; Obersteiner et al., 2001); for example, we may use biomass to make hydrogen and sequester the resulting CO2 in geologic formations. In ‘To Bury or Burn… 
Equal Opportunity for Biomass in Greenhouse Gas Accounting of CO2 Capture and Storage: A Step Towards More Cost-Effective Climate Change Mitigation Regimes
Carbon dioxide capture and permanent storage (CCS) is one of the most frequently discussed technologies with the potential to mitigate climate change. The natural target for CCS has been the carbon
Biomass with capture: negative emissions within social and environmental constraints: an editorial comment
Biomass has long been investigated both as a (nearly) CO2 neutral substitute for fossil fuels and as a means for sequestering carbon in terrestrial ecosystems (Kheshgi et al. 2000). More recently,
Biomass energy with carbon capture and storage (BECCS or Bio-CCS)
In terms of climate mitigation options, the theoretical potential of biomass energy with carbon capture and storage (BECCS) is substantial; introducing the prospect of negative emissions, it offers
Biomass energy with carbon capture and storage (BECCS): a review.
This is a review paper intended to provide an overview of debates relating to BECCS or bio-CCS, which are alternative terms for the coupling of bioenergy with carbon capture and storage (CCS). The
Carbon Capture and Storage From Fossil Fuels and Biomass – Costs and Potential Role in Stabilizing the Atmosphere
The capture and storage of CO2 from combustion of fossil fuels is gaining attraction as a means to deal with climate change. CO2 emissions from biomass conversion processes can also be captured. If
Carbon Sequestration in Forest Ecosystems as a Strategy for Mitigating Climate Change
Under Kyoto, forestry activities that sequester carbon can be used to create CO2 offset credits that could obviate the need for lifestyle-changing reductions in fossil fuel use. Credits are earned by
Economics of Forest Ecosystem Carbon Sinks: A Review
Carbon terrestrial sinks are seen as a low-cost alternative to fuel switching and reduced fossil fuel use for lowering atmospheric CO2. In this study, we review issues related to the use of
Carbon mitigation with biomass: An engineering, economic and policy assessment of opportunities and implications
Integration of biomass energy technologies with carbon capture and sequestration could yield useful energy products and negative net atmospheric carbon emissions. We survey the methods of integrating
Ocean sequestration of crop residue carbon: recycling fossil fuel carbon back to deep sediments.
This paper shows that removal of crop residues and burial in the deep ocean is 92% efficient in sequestration of crop residue carbon while cellulosic ethanol production is only 32% efficient, and soil sequestration is about 14% efficient.
OxyFuel combustion of Coal and Biomass
Oxy-fuel combustion is suggested as one of the possible, promising technologies for capturing CO2 from power plants. The concept of oxy-fuel combustion is removal of nitrogen from the oxidizer to


To Bury or to Burn: Optimum Use of Crop Residues to Reduce Atmospheric CO2
We argue that sequestering of carbon waste is inherently more efficient andwill probably cost less than using the carbon for biomass burning. The ratioof carbon emitted per unit of primary energy
Sinks, Energy Crops and Land Use: Coherent Climate Policy Demands an Integrated Analysis of Biomass
The large natural carbon fluxes between atmosphere and terrestrial biosphere in combination with our substantial control over terrestrial biotic productivity (Vitousek et al., 1986) grants us a

Sequestering of Atmospheric Carbon through Permanent Disposal of Crop Residue
We propose the sequestering of crop residues to capture a significant fraction(12%) of the present U.S. atmosphericcarbon emission through disposal in deep oceans below the thermocline or inriver
Managing Climate Risk
Increasing deployment of sustainable bioenergy with carbon removal and sequestration, together with structural shift toward low carbon-intensive fuels, will turn out to be instrumental for such a risk-limiting regime and might offer ancillary benefits for sustainable development.
