| 1~4 (Lab-level research) | Screening-level life cycle greenhouse gas analysis- Contribution and sensitivity analysis shall be used to assess opportunities for improvement- 1-3 shall demonstrate the potential to have lower GHG emissions than the Comparison Product System with identified research areas/actions to reduce the GHG emissions. TRL 4 LCAs must demonstrate the project has a lower life cycle GHG emission profile than the comparison product system. Comparison Product System shall be modeled based on the level of known market information.Industry standard or proxy data are considered acceptable for TRL 1-3. |
| 5~6 (Scale-up demonstration) | Project-level life cycle greenhouse gas analysisAt this stage in the technology development, knowledge from the scale-up demonstrations shall be used to inform the LCA modeling, site specific conditions shall be used where applicable (known), and the scale of technology market potential shall be considered (consequential effects of market scale). |
| 7 (Commercial scale system demonstration) | Project-level life cycle greenhouse gas analysis- Same as 5-6 Scale-up Demonstration requirements. Expectation is to update the technical performance and site-specific knowledge to validate real-world performance. |
| 8 (Commercial scale learning) | Project-level life cycle greenhouse gas analysis- Modeling assumptions shall reflect real-world conditions based on primary data collection from commercial scale system demonstration. |
