Twelve plans to recycle CO2 emissions into liquid fuels and chemical precursors cost-competitively with petroleum-sourced products. Pairing their technology with renewable electricity and using water and electricity as the only inputs, Twelve's industrial processes would be carbon neutral and even carbon negative for some products. The core of their technology is an energy-efficient reactor that is scalable and readily integrated into a number of industrial manufacturing process flows. Twelve was in the inaugural cohort at the Cyclotron Road accelerator at Lawrence Berkeley Labs, was the winner of the Transformational Idea Award at the 2015 DOE/Caltech FLoW competition, and won Fortune's clean tech startup competition.
