Injecting CO₂ into cement to make super-strong low-carbon concrete

Description

CarbonCure's carbon dioxide removal (CDR) technology offers permanent, verifiable, and scalable carbon reductions for the concrete industry. The retrofit technology is installed in hundreds of concrete plants globally, and the company is continuing to launch new innovative products and technologies. CarbonCure's technology won the grand prize in the $20 million NRG COSIA Carbon XPRIZE competition, selected as the most scalable breakthrough technology to convert CO₂ emissions into usable products. CarbonCure was also recognized as Cleantech Group's North American Company of the Year in 2020.

For blended vintages of 2022 to 2024, CarbonCure may deliver credits with a vintage falling within any of those years (inclusive).

Technology and mechanism

Concrete Injection

Injecting captured CO₂ into concrete mix during the production process to create strengthened concrete, as the CO₂ becomes chemically converted into a mineral.

Mechanism

Avoidance & Removal

Durability

The durability of this project is extremely high as a result of the technology used. CO₂ mineralization in concrete is a permanent storage solution. The CO₂ is stored for thousands of years and will not be released, even if the concrete is eventually crushed.

Project details

Emissions reduced or carbon removed on an annual basis

32,027 tonnes

How the project approaches risk of reversal

The project is not exposed to reversal risk. The reductions are measured, and VCUs issued, ex post. Carbon removal cannot be reversed (no situation under which end of life concrete is treated such that CO₂ is re-released). That said, a monitoring report is published for each issuance and so any updates to the project are made public.

What actions would be taken by the project developer if anticipated emissions reductions do not take place, or if carbon removal is reversed in the future?

This is not applicable for this project type.

What calculation methods are used to independently reproduce and verify the carbon impact of the project?

Please refer to Section 8 of the methodology document.
