This page is about the intersection of negative emissions technologies and machine learning in the context of climate change mitigation. For an overview of carbon dioxide removal as a whole, please see the Wikipedia page on this topic.
Negative Emission Technologies (NETs), often referred to as Carbon Dioxide Removal (CDR), aim to artificially remove carbon dioxide (CO2) from the atmospere[1], in addition to the natural removal of the atmospheric CO2 by the natural carbon sinks (such as land and ocean)[2]. NETs are not a substitution for climate mitigation and reducing global emission rate, but can be used together with mitigation efforts to speed up the reduction of emissions and reaching the net-zero emission targets sooner, depending on the emission scenario. The mitigation pathways consistent with reaching the 1.5 °C target (reported by the IPCC Special Report on 1.5 Degrees[3]) entail low to moderate levels of CDR (up to 1000 PgC removed; IPCC SR1.5 Chapter 2[4]). NETs are also an underlying assumption of overshoot scenarios -where a given temperature target is temporarily exceeded and then returned to with the aid of negative emission. While global mean temperature has shown to be largely reversible in response to artifical carbon dioxide removal, other components of climate change (such as sea-level rise, ocean acidification, and other terrestrial and marine ecosystem changes) are not easily reversible on human time-scales, even if extremely large amounts of NETs were implemented[5][6][7].
![](http://static.miraheze.org/climatetestwiki/thumb/6/65/NETs_hr.jpg/300px-NETs_hr.jpg)
Different groups of negative emission technologies[9]:
- Direct Air Capture (DAC) with sequestration of the captured CO2 in underground geologic formations.
- Bioenergy carbon capture and sequestration (BECCS)
- Biochar and soil carbon sequestration (SDS)
- Afforestation and reforestation (growing more trees and storing carbon in this biomass)
- Regenerative farming practices
- Enhanced weathering
- Ocean fertilisation
Many DAC technologies are in early stages of commercialization[10][11], though there is still large uncertainty regarding geological storage of captured CO2 on long time-scales, and deployment of negative emission technologies on large-scales and in a sustainable way is unlikely[12][13][14]. The underlying chemical processes are fairly well understood and the design of these systems generally does not require machine learning; however, ML may be useful in designing more effective CO2 sorbents. ML also may have a number of applications in CO2 sequestration, namely in identifying, modeling, and monitoring CO2 sequestration sites.
Many of the ML applications we discuss below are either speculative or in the early stages of development or commercialization[15].
Machine Learning Application Areas[edit | edit source]
- Accelerated materials discovery of new chemical sorbents: One potentially promising ML application for DAC is accelerated materials discovery of new chemical sorbents that either bind to atmospheric CO2 with either greater selectivity or have lower energy input requirements.
- CO2 migration modeling: For carbon capture and sequestration to be effective, it must sequester CO2 for hundreds or thousands of years. Thus, understanding the long-term migration of sequestered CO2, particularly in underground saline reservoir formations but also in basalts, is of critical importance. Machine learning can help speed up computationally intensive reservoir simulation models by orders of magnitude, accelerating the speed at which scientists can answer key questions.
- Identification of CO2 sequestration locations: ML can help identify and characterize potential CO2 storage locations. In particular, oil and gas companies have had promising results using ML for subsurface imaging based on raw seismograph traces;[16] these models and the data behind them could likely be repurposed to help trap CO2 rather than release it.
- CO2 sequestration site monitoring: ML can help monitor and maintain active sequestration sites by analyzing sensor measurements, and by monitoring for CO2 leaks.
