What They Do
Twelve operates in the carbon transformation and chemical technology sector, focusing on converting CO₂ into profitable chemicals and fuels. The company describes its technology as "industrial photosynthesis" (source: twelve.co). Unlike traditional renewable energy companies focused on generation or storage, Twelve's business model centers on capturing emissions and chemically transforming them into useful products. Their breakthrough technology utilizes polymer electrolyte membrane electrolysis to convert CO₂ and water into valuable chemical building blocks (source: twelve.co). This innovative approach allows them to produce a range of products, including sustainable aviation fuel and various chemical feedstocks, thereby addressing the urgent need for sustainable solutions in multiple industries.
Projects & Track Record
Twelve has established significant partnerships and projects that highlight its market traction and innovative capabilities. Notably, in February 2020, Twelve collaborated with Mercedes-Benz and Trinseo to create the world's first C-pillar made with polycarbonate derived from CO₂ electrolysis (source: twelve.co). Additionally, in March 2021, they partnered with Procter & Gamble to produce carbon-negative ingredients for Tide detergent (source: twelve.co). Their technology has also been applied in the aviation sector, with partnerships involving Alaska Airlines and the U.S. Air Force for sustainable aviation fuel applications (source: twelve.co). These collaborations underscore Twelve's commitment to transforming CO₂ emissions into valuable products across various industries.
Recent Developments
In June 2022, Twelve announced a significant $130 million Series B funding round, which was led by DCVC and the Chan Zuckerberg Initiative (source: twelve.co). This funding is intended to support the company's plans to build an industrial-scale carbon transformation platform, allowing them to deploy their reactor systems at partnered manufacturing locations (source: twelve.co). More recently, in May 2023, Twelve partnered with Emerging Fuels Technology to further develop sustainable aviation fuel (source: twelve.co). This ongoing expansion and collaboration reflect the growing confidence in Twelve's technology and its potential to significantly impact the market.
Working There
Twelve operates as a science and engineering company with roles spanning research and development, operations, environmental health and safety (EH&S), product ecosystem management, and business development. Recent job postings indicate active hiring in Moses Lake, Washington, and Berkeley, California (source: jobs.ashbyhq.com). The company prides itself on being mission-driven, focusing on creating a "fossil-free future" and addressing climate change through innovative chemistry (source: twelve.co). While specific benefits documentation is not available, the company's access to world-class resources and purpose-built R&D facilities suggests a strong commitment to employee development and a supportive work environment.
