As suspected the Commercial Demonstration Plant , as originally designed is just a pilot plant at this stage. Contrary to Tim's explanation of TRL8 (requiring the first commercial deal), ARENA says this. (Perhaps they are imposing further capacity performance). We've been told the tech was "proven" at the pilot stage. This wait is excruciating.

Systems operations

TRL 9

Actual system operated over the full range of expected mission conditions

The technology is in its final form and operated under the full range of operating mission conditions. Examples include using the actual system with the full range of wastes in hot operations.

System commissioning

TRL 8

Actual system completed and qualified through test and demonstration

The technology has been proven to work in its final form and under expected conditions. In almost all cases, this TRL represents the end of true system development. Examples include developmental testing and evaluation of the system with actual waste in hot commissioning. Supporting information includes operational procedures that are virtually complete. An Operational Readiness Review (ORR) has been successfully completed prior to the start of hot testing.

TRL 7Full-scale, This represents a major step up from TRL 6, requiring similar demonstration of an actual system prototype
