Continued independent production of sound and independent TEA and/or LCA for existing and new DACCS technologies refers to the urgency of conducting independent TEA and LCA studies for emerging and already existing DAC technologies while ensuring that measured performance data (e.g., from pilot and demonstration plants) becomes publicly available to underpin TEA and LCA studies. Both types of studies rely on vast amounts of good quality data input and, therefore, it is critical that key system parameters and resource requirements are disseminated to the public domain. This becomes more important as commercial-scale plants come online so the field can quickly learn and evolve.
