the carbon transformation company™

Twelve is the carbon transformation company, on a mission to eliminate global emissions and build a fossil-free future by transforming CO2 into essential products through the power of electrochemistry. Our breakthrough Opus™ Carbon Transformation System is an industrial-scale electrolyzer that that that works like photosynthesis, converting CO2, water and renewable energy into hydrocarbons, the building blocks for chemicals, materials and fuels. By using CO2 as a feedstock, we can eliminate emissions from products and supply chains, and eliminate the need for fossil fuels as a feedstock for thousands of industrial and everyday products.
