Capturing waste biogenic CO₂
Fermentation sources are a relatively unexplored carbon removal source. Carbon Capture Scotland, who has recently rebranded to The Carbon Removers, focuses on capturing waste biogenic CO₂ from whisky distilleries and storing it permanently. Their proprietary technology reduces the cost and energy footprint of capturing and processing high-purity CO₂ and allows for accurate measuring and reporting along the supply chain.
Durable carbon removal (CDR)
CDR is one of the most crucial solutions to reach and maintain net-zero emissions and limit global warming. To counterbalance fossil emissions from the long carbon cycle, the carbon removed needs to be stored durably. While solutions for durably removing carbon are still nascent, pre-purchasing carbon removal from startups can help kickstart the sector, making it an affordable and climate-relevant solution in the future. When credits or certificates are bought, they will be retired, meaning they cannot be resold and will not be counted as financial instruments.
Bio Energy Carbon Capture and Storage (BECCS)
In BECCS, biomass that absorbs CO₂ while growing is combusted in power plants or used for biogas production, releasing CO₂. Flue gases (emissions from burning fuel) are captured by a Carbon Capture and Storage (CCS) unit, where the CO₂ is separated and liquefied for transport. The CO₂ can then be transported to storage sites injected deep underground, storing it permanently.

Backwater introduces an innovative, shallow-depth geological storage method for dissolved CO₂. This novel approach expands geographic accessibility, enabling co-location of CO2 capture and underground storage. By eliminating transport and reducing well costs, Backwater makes smaller projects cost-effective and unlocks untapped CDR potential in storage-constrained regions.

South Africa
CHAI will work on the high impact project of transitioning a portfolio of hospitals in South Africa's Western Cape Province to renewable energy. This could be a high impact measure that is currently not occurring due to the limited capacity of the department of health and because of bureaucratic hurdles to innovative financial and energy contracts. The project has the potential to reduce emissions by hundreds of thousands of tons, and leverages CHAI's extensive experience in health sector procurement and innovative finance.

Tanzania
This project develops a mobile app for regreening techniques like Farmer Managed Natural Regeneration (FMNR). The app delivers real-time, location-specific advice directly to farmers' phones. This approach reduces intervention costs by eliminating the need for in-person visits to every location. We already support Justdiggit’s regular work since 2021, and now added this project because it builds on proven FMNR methods, increasing cost-efficiency and potential for rapid scaling in dry landscapes.
