2. Technology readiness level (TRL)
Science & Engineering · Engineering Abbreviations
Nine-step scale for gauging the maturity of a technology, from TRL 1, basic principles observed, to TRL 9, a system proven in actual operation. Government agencies and investors use TRLs to judge development risk and decide what to fund.
Example: The battery chemistry is at TRL 4, validated in the laboratory but not yet in a full-size prototype.
NASA researcher Stan Sadin conceived the scale in 1974, and NASA formalized nine levels in the 1990s. The US Department of Defense, the European Union and many energy agencies now use adapted versions. Projects often stall in the "valley of death" around TRL 4-6, between lab success and commercial deployment.
