Sumitomo and Graphyte launch U.S. venture to scale biomass carbon removal, expand CDR credits, and accelerate durable decarbonization efforts.
Sumitomo Corporation and Graphyte, a U.S. decarbonization startup, have established a joint venture in the United States to scale the Biomass Carbon Removal and Storage (BiCRS) business and accelerate the generation and sale of Carbon Dioxide Removal (CDR) credits. Sumitomo Corporation holds a 49% equity stake, while Graphyte retains 51% in the new entity. This collaboration aims to address the rapidly growing demand for high-quality, verifiable, and durable carbon removal solutions crucial for achieving global net-zero targets.
The core of this venture lies in Graphyte's proprietary "Carbon Casting" technology. This innovative process involves collecting biomass residues, such as wood by-products from timber operations and agricultural waste like rice hulls, which would otherwise decompose and release CO2 into the atmosphere. These materials are then processed, compressed into dense blocks, sealed to prevent decomposition, and stored permanently underground, ensuring carbon sequestration for over 1,000 years. Graphyte emphasizes that this technology is characterized by its high durability, cost-competitiveness (reportedly under $100 per ton, with potential for further reduction), and immediate scalability, leveraging existing, off-the-shelf equipment and readily available biomass feedstocks. The company is backed by Breakthrough Energy Ventures, a climate and clean energy investment fund founded by Bill Gates.
The joint venture will initially focus on Graphyte's operational "Loblolly" project in Pine Bluff, Arkansas, which utilizes rice hulls and is currently expanding its capacity to remove approximately 50,000 metric tons of carbon dioxide annually. Graphyte has a proven track record, having made on-time credit deliveries and securing significant purchase agreements with major corporations like American Airlines and JPMorgan Chase for its CDR credits.
This partnership is driven by the increasing global emphasis on decarbonization and the recognition that emissions reductions alone are insufficient to meet climate goals, necessitating substantial carbon dioxide removal. The market for carbon credits, particularly those generated through negative emission technologies like BiCRS, is projected for substantial growth, from an estimated 2.1 billion to 80 billion by 2030.
Economically, the venture is poised to create a robust market for CDR credits, attracting significant investment and fostering job creation, particularly in rural communities where biomass resources are abundant. For instance, projects like Loblolly in Arkansas and a developing site in Arizona, Project Ponderosa, aim to generate additional income streams for local farmers and mill operators by utilizing agricultural and forestry residues. From an industry perspective, this collaboration validates and accelerates the deployment of BiCRS as a viable, durable, and scalable carbon removal solution. It also highlights Sumitomo Corporation's strategic commitment to carbon neutrality, viewing carbon capture, utilization, and storage (CCUS) as a crucial tool. Environmentally, the initiative offers a pathway to permanently remove billions of tons of CO2 from the atmosphere, significantly contributing to global efforts to combat climate change. The joint venture plans to further accelerate the development and expansion of its business portfolio through participation in multiple projects across North America.
