COMPANY DESCRIPTION
Yuanchu, is a leading start-up dedicated to developing disruptive direct air mineralization (DAM) technology for removing CO2 from air and permanently sequestering it into solid carbonated material at gigatonne scale. The mineralization products keep stable for 1000 years.
CORE INNOVATION
There are three main differentials with our technology:
1. Capture and sequestration of carbon dioxide are completed in one step;
2. High reaction efficiency (>90%);
3. Low capital cost, less than $100 per tonne CO2 when scaling up to the megatonne level or gigatonne level.
CO2 CAPTURE
The CO2 in the air flows into the YAM mineralization reactor and reacts with Ca2+ from the feedstock (natural minerals, industry waste) to directly form calcium carbonate. It combines the carbon capture and mineralization into one step, which significantly reduces the CapEx and OpEx.
CO2 SEQUESTRATION
Calcium carbonate, as the main reaction product, is the most stable chemical form of carbon and can stably sequester carbon dioxide for over thousands of years.
CO-BENEFITS OR PRODUCTS
We are utilizing the calcium resource from either industrial waste or natural ores. Once we use the industrial waste as the feedstock to form carbonates, it can be used as mine fillers, bulk building materials aggregates or road materials, forming a circular economy to recycle industrial waste materials.
