What Graphyte does

Graphyte, Inc. is a privately held U.S. carbon dioxide removal (CDR) company founded in 2023 and headquartered in Memphis, Tennessee, that sells durable carbon removal credits to corporate buyers using a proprietary process the company calls Carbon Casting. The five-step process collects agricultural and forestry biomass residues, dries and sterilizes them to eliminate microbial decomposition, compresses the material into dense carbon blocks, wraps them in an impermeable polymer barrier, and stores them in monitored underground chambers (dry-tomb storage) with sensors and tracers. The company reports up to 98% carbon removal efficiency, 1,000+ year durability, and roughly 10% of the energy requirements of direct air capture, making the technology deployable in electricity-constrained markets.

Graphyte operates as a single-product company through its flagship Loblolly Project in Pine Bluff, Arkansas, which opened in April 2024 and is described as the world's largest carbon removal plant, with annual operational capacity of 50,000 tCO2e achieved by early 2025 and a target expansion to 65,000 tCO2e/year by August 2026 via a project-level joint venture with Sumitomo Corporation. The company has issued over 15,000 durable CDR credits through the Isometric registry and earned the world's first CCP-labeled credits (ICVCM) and the first 'AA' BeZero carbon rating for a biomass-based CDR method. Revenue is generated through transaction-based, multi-year credit purchase agreements with large enterprise buyers including JPMorgan Chase (60,000-ton, 10-year deal), Microsoft, and NYK Group, supplemented by project-level equity investment from strategic partners (Sumitomo, 49% of the Loblolly subsidiary).

The go-to-market is sales-led, combining direct enterprise sales of negotiated multi-year offtakes with channel partnerships through Carbon Direct (offtake and quality alignment), Isometric (registry and distribution across 30+ marketplaces), and international strategic partners (Sumitomo, NYK). Expansion is under way into new geographies (Arizona, British Columbia, and via Sumitomo into Japan/Asia) and new verticals (shipping's residual emissions and wildfire fuel reduction). The company is backed by Breakthrough Energy Ventures, Carbon Direct Capital, Overture Ventures, and Prelude Ventures, with total disclosed funding of approximately $43.5M plus a $30M Series 2 in July 2024.

Revenue model

1. Carbon Removal Credit Sales: Graphyte generates revenue by selling durable carbon dioxide removal (CDR) credits to corporate buyers. Credits represent one metric ton of CO2 removed and permanently sequestered via the Carbon Casting process. Credits are certified through the Isometric registry and priced at a fraction of competing technologies. Deals include both forward purchase agreements (e.g., 10-year JPMorgan deal for 60,000 tons) and spot/annual credit purchases (NYK shipping credits). Deliveries are guaranteed within 2 years of purchase year.
2. Project-level Equity Investment: Sumitomo Corporation acquired a 49% equity stake in the Graphyte subsidiary operating the Loblolly project, valued in the billions of yen. This project-level financing model generates capital for expansion in exchange for a percentage of additional revenue from the Loblolly facility and future projects.

Direct peers

• Vaulted Deep: Vaulted Deep uses subsurface burial of biomass waste for durable CDR. It is one of Graphyte's closest direct peers in the BiCRS category, sharing the durable CDR registry (Isometric) and a comparable funding scale ($48.3M raised).
• Charm Industrial: Charm Industrial converts biomass into bio-oil and sequesters it underground as a form of durable CDR. Like Graphyte, it operates in the BiCRS category, is one of the top three Isometric credit issuers, and has raised substantial venture funding ($125M).
• Heirloom Carbon: Heirloom uses limestone-based direct air capture to remove CO2 from the atmosphere and mineralize it for permanent storage. It is a direct peer in the durable CDR market, targeting the same enterprise buyer base seeking high-integrity removal credits.
• CarbonCure Technologies: CarbonCure injects captured CO2 into concrete for mineralization-based permanent storage. It is comparable to Graphyte as a mineralization/carbon-cured-materials CDR developer and sells to enterprise customers seeking durable, measurable removal.

Emerging players

• CarbonCapture Inc. CarbonCapture Inc. develops direct air capture systems focused on scalable, modular designs. It overlaps with Graphyte in the durable CDR enterprise sales motion but uses a different (DAC) capture mechanism and is at an earlier commercial stage.
• Carbofex: Carbofex produces biochar from forestry residues and sells carbon removal credits. It overlaps with Graphyte's biomass-based approach but uses thermal pyrolysis rather than the Carbon Casting dry-tomb storage method, and operates primarily in Northern Europe.
• CarbonOrO: CarbonOrO uses enhanced rock weathering (olivine-based mineralization) to permanently sequester atmospheric CO2. It is comparable to Graphyte as a durable CDR provider targeting corporate buyers, though its mechanism (mineralization) is distinct from biomass burial.

Broad incumbents

• Climeworks: Climeworks is the global leader in direct air capture, operating the Orca and Mammoth plants and serving the same enterprise buyer base for durable CDR. It competes for corporate offtake commitments and is a broad incumbent in the high-integrity CDR category.
• 1PointFive: 1PointFive (Occidental's DAC subsidiary) operates Stratos, one of the world's largest DAC facilities, and markets CDR credits to enterprise buyers. It is a broader incumbent competing for the same corporate offtake demand with significantly larger capital backing.

Others

• Carbon Direct: Carbon Direct is both an offtake partner and investor in Graphyte, providing scientific quality assurance, advisory services, and a buyer channel. It is an enabling ecosystem participant rather than a direct competitor but is highly relevant given its strategic position in the durable CDR market.
