The economics of direct air carbon capture and storage

by Eric Williams, Global CCS Institute, 26 pp.

This paper explores the economics of DACCS. The intent is a thought experiment to show how DACCS deployment (based on different cost assumptions) might affect the global energy system through 2065 while maintaining a net-zero CO2 pathway consistent with a 1.5°C global average temperature increase. The analysis relies on the economic model described in the methodology, in which the actors within the energy system are free to pursue least-cost options in meeting the net-zero CO2 pathway.

Bio-oil Sequestration: Prototype Protocol for Measurement, Reporting & Verification

Carbon Direct and Eco-Engineers have developed a prototype protocol (“proto-protocol”) on bio-oil sequestration, the first in a series of science-led draft protocols. In collaboration with Charm Industrial, this analysis focuses on the carbon accounting, life-cycle analysis, and monitoring, reporting, and verification (MRV) foundations for a new carbon removal practice: bio-oil sequestration and geological disposal. It also includes an understanding of the energy requirements in biomass cultivation, harvesting, and conversion as well as a focus on subsurface characterization and operational excellence.

Policy brief: Soils Research to deliver Greenhouse Gas Removals and Abatement Technologies (SOILS-R-GGREAT)

UK GGR Research Programme

Through new research on global croplands SOILS-R-GGREAT researchers have estimated that arable farming has produced a loss of around 25 Gt carbon relative to the natural state in 1975 but, since that time, there has been an addition of about 4Gt of soil organic carbon (SOC) due to improved agricultural practices. Alongside agricultural management, approaches such as addition of biochar or enhanced weathering of silicate rocks on soils can improve carbon storage. Researchers present possible CO₂ sequestration from these two techniques in Sao Paulo State, Brazil.

Report: Barriers to scaling the long-duration carbon dioxide removal industry

by Na’Im Merchant, Freya Chay, Danny Cullenward, Jeremy Freeman on carbonplan.org

The private market for CDR is growing. But what about quality standards? In a series of interviews with stakeholders from the field, nonprofit research group CarbonPlan asks how the lack of third-party verification for carbon removal purchases could impact the industry and if government policy can help.

Building a shared language: Carbon Gap releases French-language carbon removal brief

Carbon Gap’s core announce the release of Understanding Carbon Dioxide Removal (French title: L’élimination du carbone atmospherique), a collaboration between Carbon Gap, Zenon Research, and Mines Paristech, to develop French-language carbon removal content that will serve to inform and inspire future commitments to carbon removal by the French government. The six-page brief provides a general overview of the science of carbon removal, its role in addressing climate change, and the various methods that can safely and reliably remove carbon directly from the air and store it, including forestation, direct air capture, biochar, mineralization, and more.

DACC Report Library

by daccoalition.org

Whether by academic institutions or NGOs, there are many reports looking at this climate solution, in terms of its technology, potential, future costs, and scalability. The DAC Coalition plans to commission reports on the state of DAC and the roadmap to scaling the DAC ecosystem. The library is indexed by topic area, author(s), date, publisher and publisher type which can be easily sorted/filtered via the Airtable layout.
