Document Description
Twelve Benefit Corporation has developed a versatile technology platform for conversion of CO2 emissions and renewable electricity to value-added chemical and fuel end products. This project conducts basic research and will result in scaled down prototype construction in a laboratory setting. One of the proposed end products is calcium formate, which can be incorporated into cement to enhance stability and drying in wet or low temperature environments. This project will optimize electrolysis technology, develop a pathway to calcium formate, demonstrate the ability to utilize CO2 from cement plant flue gas, and test the product with an industrial partner. This project will explore the full lifecycle of renewable carbon: from industrial capture to conversion to long-duration storage in cement.

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
Cal. Code Regs., tit. 14, § 15301; Cal. Code Regs., tit. 14, § 15306
Reasons for Exemption
Cal. Code Regs., tit. 14, § 15301: A project that consists of operation, repair, maintenance, permitting, leasing, licensing, or minor alteration 2) of existing structure, facilities, or mechanical equipment, 3) which involves negligible or no expansion of use beyond that existing or former use is categorically exempt from CEQA. This project includes the fabrication and assembly of electrolyzer stacks and integration of those stacks into a commercial scale electrolyzer unit for testing. The commercial scale unit is designed to fit in a standard shipping container. The commercial scale electrolyzer will be skid mounted for demonstration inside an existing facility used for research purposes. The project will not involve any construction activities such as excavation or digging. Therefore, this project is exempt from CEQA.
Cal. Code Regs., tit. 14, § 15306: The project includes conducting paper studies for LCA, TEA, and FEL-1 design, and conducting laboratory research on electrolyzer experiments, and design/planning work for CO2-to-formate pathway design and fits within the following criteria: Project consists of basic data collection, research, experimental management, and resource evaluation activities 2) Which do not result in a serious or major disturbance to an environmental resource. This project is exempt from CEQA under section 15306.
This proposed project does not impact an environmental resource of hazardous or critical concern where designated, precisely mapped, and officially adopted pursuant to law by federal, state, or local agencies; does not involve any cumulative impacts of successive projects of the same type in the same place that might be considered significant; does not involve unusual circumstances that might have a significant effect on the environment; will not result in damage to scenic resources within a highway officially designated as a state scenic highway; the project site is not included on any list compiled pursuant to Government Code section 65962.5, and the project will not cause a substantial adverse change in the significance of a historical resource. Therefore, none of the exceptions to categorical exemptions listed in CEQA Guidelines section 15300.2 apply to this project and this project will not have a significant effect on the environment.
