Seattle Startup Converts Carbon into Graphite, Secures $600K
A Seattle-area startup is making carbon capture more than just a climate solution—it’s creating a valuable resource. Homeostasis, a Tacoma-based sustainability tech company, has secured a $600,000 pre-seed investment to advance its technology. This technology removes CO₂ from the air and converts it into graphite, a critical material used in batteries, steel production, and defense applications.
The funding round comes months after the Washington State Department of Commerce awarded Homeostasis $700,000, highlighting the increasing focus on carbon removal innovations.
Startup Transforms CO₂ into High-Demand Graphite for Energy & Industry
Homeostasis’ proprietary carbon capture process, known as aqueous mineralization capture, traps CO₂ and transforms it into graphite. Currently, most graphite is mined, with China dominating global supply chains. The U.S. government has identified graphite as a critical mineral for renewable energy and national security.
With a working prototype already in place, Homeostasis is preparing pilot projects for deployment in late 2025 or early 2026. The company plans to sell its technology to industrial clients before expanding into its carbon capture facilities.
A Vision for Sustainable Industry
Co-founders Julien Lombardi (Chief Scientist) and Makoto Eyre (CEO) bring expertise in chemistry, engineering, and sustainable innovation. Investors include Kayak Ventures, the Shakopee Mdewakanton Sioux Community, and angel investors.
In a market where carbon capture startups raised $12.2 billion in 2024, Homeostasis is positioning itself as a key player in sustainable tech, solving climate challenges and critical resource shortages.
With the growing demand for domestic, sustainable graphite sources, Homeostasis’ technology could reshape industrial supply chains while reducing global carbon emissions.
