Barclay Rogers CEO of Graphyte Explains “Carbon Casting” as New Carbon Removal Technology
In this video, Barclay Rogers, CEO of Graphyte, joins ESG News’ CEO Matt Bird to explain “Carbon Casting” and its carbon removal process and technology.
Graphyte is a climate tech startup focused on carbon removal, backed by Breakthrough Energy Ventures, a fund established by Bill Gates. The company has developed a technology called “Carbon Casting,” which combines natural photosynthesis with engineered storage methods to capture and permanently sequester carbon from the atmosphere. This process involves transforming biomass—such as timber and agricultural waste—into dense carbon blocks. These blocks are then stored in underground facilities, where they are protected from decomposition, ensuring long-term carbon storage for over 1,000 years.
One of Graphyte’s key advantages is the low cost of carbon removal, estimated at less than $100 per ton. This affordability aligns with the U.S. government’s “Earthshot” goal, making it a competitive solution compared to other carbon capture technologies. Additionally, the company’s method is scalable, with the potential to significantly impact global carbon emissions by using materials that would otherwise contribute to atmospheric CO2.
