Definition of Technological Readiness Levels TRLs

Technological Readiness Levels (TRLs) serve as a metrics framework designed to evaluate the maturity of technologies. Originally conceived by NASA in the late 1970s as part of the Space Shuttle program, the purpose was to enable a structured way to assess the readiness of emergent technologies for inclusion in space missions. TRL assessments help in identifying technological gaps and in making informed decisions about project funding, planning, and risk management.

The TRL scale consists of nine distinct levels, each representing a phase of development. Level 1 denotes the basic principles observed, while Level 9 signifies that the technology has been proven in an operational environment:

Level	Description & details (note: exemples are fictive, for understanding)
TRL 1	Basic principles observed: scientific research begins to translate into applied research and development. Activities might include paper studies of a technology’s basic properties. Quantum-enhanced solar cells: researchers would discover that incorporating quantum dots into solar cells can potentially increase efficiency by exploiting quantum tunneling effects. Biodegradable superconductors: scientists would identify a naturally occurring polymer with properties that could allow it to function as a superconductor at room temperature.
TRL 2	Technology concept formulated: invention begins. Once basic principles are observed, practical applications can be invented. Activities are limited to analytic studies. Self-sealing Concrete: engineers would propose a concrete mix that incorporates bacteria capable of producing limestone to self-repair cracks over time. Wireless power transfer for Electric vehicles: a concept that would be developed for charging electric vehicles without physical connectors by using magnetic resonance.
TRL 3	Analytical and experimental proof of concept: active research and development begin, including both analytical studies and laboratory experiments to validate that the theoretical predictions are correct. Solar-powered water purification: a prototype device built that uses solar energy to distill and purify water, demonstrating the basic functionality in a lab setting. AI-driven drug discovery: an artificial intelligence algorithm that would be developed and tested in a controlled environment to predict molecular structures that could lead to new pharmaceuticals.
TRL 4	Technology validated in lab environment: technology validated through designed investigation. Examples might include analysis of the technology parameter operating range. The results provide evidence that envisioned application performance requirements might be attainable. Biodegradable packaging material: a prototype of a new biodegradable plastic that would be tested in a laboratory to ensure it decomposes within a specified time frame without releasing harmful substances. Electric aircraft propulsion system: components of an electric propulsion system that would be integrated and tested in a laboratory environment to verify their performance and efficiency.
TRL 5	Technology validated in relevant environment: reliability of technology significantly increases. Examples could involve validation of a semi-integrated system/model of technological and supporting elements in a simulated environment. Autonomous delivery drone: a semi-integrated drone system that would be tested in a controlled outdoor environment to simulate real-world delivery scenarios. Advanced water filtration system: a water filtration unit that would be installed in a simulated urban setting to assess its performance in treating contaminated water sources. A well-documented case is NASA’s Mars rovers: it progressed from simulation models (TRL 4) to functional prototypes (TRL 5) before actual deployment.
TRL 6	Technology demonstrated in relevant environment: prototype system verified. Examples might include a prototype system/model being produced and demonstrated in a simulated environment. Smart traffic management system: a prototype system that would be deployed in a mid-sized city to manage traffic flow using real-time data analytics and adaptive signal control. Wearable health monitoring device: a fully functional prototype that would be tested in a clinical setting to monitor patients’ vital signs and detect early signs of health issues.
TRL 7	System prototype demonstration in operational environment: a major step increase in technological maturity. Examples could include a prototype model/system being verified in an operational environment. Electric bus fleet: a fleet of electric buses that would be deployed in a metropolitan area to assess their performance, energy consumption, and integration with existing infrastructure. Smart grid energy distribution: a smart grid system that would be implemented in a regional area to optimize energy distribution and integrate renewable energy sources effectively.
TRL 8	Actual system completed and qualified through test and demonstration: system/model produced and qualified. An example might include the knowledge generated from TRL 7 being used to manufacture an actual system/model, which is subsequently qualified in an operational environment. Commercial solar-powered desalination plant: a fully operational desalination plant that would be powered entirely by solar energy is constructed and being tested to provide potable water in arid regions. Autonomous public transportation network: an autonomous vehicle network that would be established in a city, providing public transportation services without human drivers, and is fully integrated into the city’s infrastructure.
TRL 9	Actual system proven in operational environment: system/model proven and ready for full commercial deployment. An example includes the actual system/model being successfully deployed for multiple missions by end users. Global electric aviation network: a network of electric...
