Project Status

Project Update

As of February 21, 2025, the project has commenced and the first year has been completed with project progress (fiscal and technically) proceeding as planned. The Design Package Report was received January 13, 2025, and the CEC is currently awaiting the Full Stack Validation and Procurement Report.

The Issue

Project Innovation

Twelve Benefit Corporation, a California-based startup, is developing a novel and scalable electrochemical process to convert carbon dioxide (CO2), a readily available industrial waste gas, into building blocks for chemicals and fuels. This process utilizes water, renewable electricity, and CO2 as inputs, and produces high value intermediates as outputs.

Project Goals

To fund development, scale-up, and testing of a pathway from carbon dioxide to calcium formate, a cement additive.

Project Benefits

The proposed two step pathway can use flue gas CO2 captured from a cement plant to synthesize CO and subsequently calcium formate, which will be incorporated back into concrete production as a CO2-derived additive.

Environmental & Public Health

Environmental Sustainability

This Agreement will result in the ratepayer benefits of greater electricity reliability, lower costs, or increased safety by reducing renewable energy overgeneration, reducing CO2 emissions state-wide, and stabilizing the electric grid.
