The key results of Deliverable 3.1 are two technology inventories for promising low-emission technologies in the steel and petrochemical industries as part of the EU-China BRIDGE project. These inventories are intended to support the transition to climate-neutral industries in Europe and China. They contain detailed descriptive and quantitative data on selected breakthrough technologies, including TRL and development status. The technologies were selected based on criteria such as net-zero compatibility and high CO₂ reduction potential. The inventories are publicly available as Excel files on Zenodo and are used internally for technology roadmaps and techno-economic modelling. The technology data are also converted to an interactive interface on the I2AMParis platform.
