Carbon-dioxide Fixation01:28

Carbon-dioxide Fixation

872
Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

The Carbon Cycle01:14

The Carbon Cycle

45.6K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

Bioremediation

22.9K
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

C4 Pathway and CAM01:27

C4 Pathway and CAM

50.7K
Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.

Area of Science:

  • Environmental science
  • Climate technology
  • Carbon capture and storage

Background:

  • The voluntary carbon market (VCM) supports carbon dioxide removal (CDR) technologies.
  • Direct air capture with storage (DACS) is an energy-intensive CDR technology.
  • Accurate emissions accounting is vital for DACS to qualify for the VCM.

Purpose of the Study:

  • To assess the impact of different electricity emissions accounting methods on DACS net removal.
  • To evaluate the sensitivity of DACS net removal to various operational and grid factors.

Main Methods:

  • Simulated hourly operation of sorbent- and solvent-based DACS in diverse US locations (CA, LA, TX, WY).
  • Analyzed the influence of weather-dependent energy consumption and grid compositions.
  • Quantified the effect of various electricity emissions accounting methodologies.

Main Results:

  • Electricity emissions accounting method is the most critical factor, causing net removal variations from -1049% to +108%.
  • Other factors (e.g., construction, natural gas) caused variations of at most ±14%.
  • No single accounting method proved universally conservative or accurate across all scenarios.

Conclusions:

  • Accurate DACS emissions accounting is highly sensitive to the chosen electricity accounting method.
  • Current data and models for electricity emissions accounting lack the necessary resolution and quality.
  • Urgent need for standardized, high-quality data and models for accurate emissions impact assessment of DACS and similar technologies.
