Even with advanced AI, LCA will always require expert oversight to define appropriate system boundaries, capture bifurcation points, and validate whether results align with expected system behavior. A model that processes data quickly is not equivalent to a model that understands the underlying dynamical system it's analyzing.

The maintenance plan should outline how the Project Proponent will ensure the structural integrity of the reactor vessel to mitigate against potential material loss events. This includes suitable monitoring and mitigation for mechanical, thermal and corrosive events which may lead to failure of the vessel and subsequent release of reaction materials into the environment. All maintenance plans should be in compliance with a suitable local standard which provides regulations for the maintenance of pressure vessels, such as 2014/68/EU or an appropriate regional equivalent standard in the region o…

An appropriate reactor maintenance plan should be in place, and must be detailed in the PDD.

Suitable mass/volume flow meters must be placed on all material inlets/outlets from the reactor to allow for characterization of reactor performance and to monitor any material losses to the environment. These sensors should be positioned immediately upstream/downstream of the reactor, as appropriate. Suitable sensors to measure pressure, temperature and pH (if applicable) should be implemented to allow for accurate characterisation of the reactor performance through a combination of measurements and modeling.

The reactor design must include sensors necessary to quantify any loss of CO₂ from the feedstock during operation of the reactor to leakage. This should include, at minimum, sensors to determine the inflow/outflow of CO₂ from the reactor, which can be used in conjunction with a suitable reactor model to determine the amount of CO₂ reacted and to estimate any loss of CO₂ to leakage. Only CO₂ which has been determined by this calculation to have undergone complete chemical reaction into a solid mineral product is eligible for carbon Credits issued under this Module.

the positioning of sensors for the monitoring of flow rate, reactant/product chemical composition, temperature and pressure, details of any internal equipment such as agitators or heating/cooling coils and details of any external heat transfer equipment (including heat exchange fluid entry/exit points and corresponding sensors for flow rate and temperature). A sufficient number of viewpoints must be included in the engineering design diagram to show the positioning of all of the key components listed above. Any other process equipment essential to the safe and effective operation of the reacto…

In a Project that injects CO₂ into cement during mixing, or a Project incorporating carbonated materials into concrete, the point of storage would be verification of carbonate content. This does not include carbonation that occurs as a result of environmental exposure under ambient conditions.

Corporate office buildings, which are more likely to change in alignment with trends, may be designed with replaceability, adaptability or de-constructability in mind. It is important to note that design life of an asset is not necessarily equivalent to functional service life, which may be longer or shorter than the design life based on a variety of factors such as asset ownership, changes in regional regulatory environments, societal preferences and asset performance. A study of buildings in North America found that the majority of demolished buildings were less than 50 years old14 and the R…

Critically, appropriate humidity levels must be maintained in carbonation curing to ensure that the mechanical properties of the resulting concrete are equivalent to conventional concrete products11.

In carbonation curing, CO₂ is introduced during the curing process, resulting in carbonation according to Equations 2-4 above. Carbonation curing is applicable primarily to precast concrete elements.

carbon injection during concrete mixing has a neutral to positive effect on several key markers of concrete durability, including compressive strength 6 7, chloride penetration resistance 6, and drying shrinkage6. This is because the formation of nano-CaCO3 acts as a nucleation site, promoting hydration and may result in improved mechanical properties8. The magnitude of these effects has shown some dependence on CO₂ dose, with potential impacts to long-term concrete durability at higher doses

he relationship between CO₂ injection and concrete durability is an active area of research and is critical for furthering use cases of CO₂-storing concrete.

Using less material in the built environment and using lower embodied carbon alternatives to PC both play a key role in efforts to reduce the climate impact of the construction industry. CO₂ storage in concrete by carbonation, in which CO₂ reacts with Ca-bearing species to form carbonate minerals, is another rapidly emerging approach. On geologic timescales, carbonation of silicate rocks is part of the natural weathering process that regulates atmospheric CO₂ concentrations; this is leveraged in several Carbon Dioxide Removal (CDR) pathways, including Enhanced Weathering (EW) and in-situ or ex…
