💡What are the most promising carbon dioxide removal (#CDR) technologies?💡

AlliedOffsets have developed the world's largest project database for the carbon offsetting industry. Detailed data on the 500 projects already incorporated provides invaluable insights for our users and contributes to making the CDR market more transparent and navigable. Their Carbon Dioxide Removal (CDR)

Report for Summer 2023 presents an overview of five of the most promising CDR technologies:

1. Biochar carbon removal (#BCR)

2. Direct air capture (#DAC)

3. Bioenergy carbon capture and storage (#BECCS)

4. Ocean alkalinity enhancement

5. Enhanced weathering (#EW)

My take?

These overviews can be very helpful, especially for people less familiar with the market and its technologies. Having said that, they oversimplify and - based on the underlying data - can lead to wrong conclusions.

A few things to highlight:

🇺🇸This overview seems to imply that the US is the hub for pretty much all CDR technologies. In reality, Europe is leading the way for biochar carbon removal and enhanced weathering is certainly happening outside of the US, especially in India, Brazil, and Europe.

⏰ The sequestration potential is difficult to compare, as timelines (2030 vs 2050 vs ?) are left implicit. Further, the sequestration potential for enhanced weathering (#EW) is inexplicably low (read my post on the potential for EW here).

🏡Co-benefits did not find their way onto the comparison. A focus on benefits to communities, farmers, and individuals is crucial when comparing different CDR technologies.

I am excited for this new data set by AlliedOffsets and keen to see what knowledge assets they will continue to create for the CDR community.

❓What do you think are the most promising CDR technologies and why? Do you agree with their assessment?
