1. What are Technology Readiness Levels (TRLs)?
Technology Readiness Levels (TRLs) are a set of criteria used to assess and track the development of a technology as it moves from concept to commercialization. Initially developed by NASA, TRLs are now widely used across industries such as aerospace, defence, and manufacturing, as well as in research and development (R&D) for software, medical devices, and energy technologies.
The nine levels of the TRL scale provide a step-by-step guide to the technology development process, helping organizations and innovators:
- Evaluate the maturity of a technology
- Identify gaps and risks in the development process
- Communicate progress to stakeholders and investors
- Make strategic decisions about further investment and testing
2. The 9 Stages of Technology Readiness Levels
Here’s a breakdown of each TRL stage, from the earliest conceptual research to the final commercial product:
TRL 1: Basic Principles Observed and Reported
At TRL 1, the focus is on scientific research and the identification of basic principles. This is the very beginning of the innovation process, where ideas are conceptualized and theories are developed. At this stage, the technology is still theoretical and far from any practical application.
Example: Researchers discover a new material with potential applications in energy storage, but it’s still at the experimental stage with no practical design or testing yet.
TRL 2: Technology Concept and Application Formulated
In TRL 2, the basic principles observed in TRL 1 are used to formulate a technology concept. This is where the practical applications of the idea begin to take shape. The goal is to create a vision for how the technology might solve real-world problems.
Example: Scientists propose that the new material could be used to create more efficient batteries, but the concept remains largely theoretical and requires further exploration.
TRL 3: Experimental Proof-of-Concept
TRL 3 is where the first experimental proof-of-concept is demonstrated. This often involves building small-scale, laboratory models or simulations to test whether the concept works in practice. It’s a critical stage for identifying the feasibility of the technology.
Example: A small test cell using the new material is built to see if it can indeed store energy more efficiently than existing battery technologies.
TRL 4: Technology Validated in a Lab Environment
At TRL 4, the technology moves beyond theoretical testing to real-world validation in a laboratory environment. Here, the focus is on creating a functional model or prototype that demonstrates the technology’s core components and performance.
Example: A prototype battery using the new material is developed and tested under controlled laboratory conditions, showing promise for further development.
TRL 5: Technology Validated in a Relevant Environment
TRL 5 involves taking the technology out of the lab and testing it in a relevant environment – one that closely mimics the conditions in which the final product will be used. This is an important step for understanding how the technology will perform in more realistic scenarios.
Example: The new battery prototype is tested in a simulated industrial setting, where it’s subjected to various stressors, such as temperature changes and load cycles, to see how it holds up.
TRL 6: Technology Demonstrated in a Relevant Environment
At TRL 6, the technology is further developed into a more sophisticated prototype and demonstrated in a relevant or operational environment. This is where more rigorous testing occurs, and the prototype may undergo iterations based on feedback from initial tests.
Example: A full-scale battery system is integrated into a pilot plant or an industrial site to assess its real-world performance, efficiency, and durability over time.
TRL 7: System Prototype Demonstration in an Operational Environment
In TRL 7, the technology is nearing maturity, with a prototype system being tested in an operational environment. The prototype should now closely resemble the final product and is put through extensive trials to verify its functionality and integration with other systems.
Example: A near-final version of the battery system is installed in a working power grid or energy storage facility, undergoing long-term testing under actual operating conditions.
TRL 8: Actual System Completed and Qualified Through Testing
At TRL 8, the technology is now a complete system that has been fully tested and validated. The product is finished, and extensive trials confirm that it meets performance, safety, and regulatory requirements. At this stage, the technology is nearly ready for market launch.
Example: The battery system is now fully operational and has passed all safety, efficiency, and durability tests. It is ready to be manufactured and deployed on a larger scale.
TRL 9: Actual System Proven in Operational Environment
TRL 9 is the final stage, where the technology is proven to work in real-world operational environments. It has been manufactured, deployed, and is now in regular use, demonstrating its reliability and effectiveness in the market.
Example: The battery system is commercially available and widely used in energy storage facilities, providing a reliable solution for grid stabilization and renewable energy integration.
3. Benefits of Using TRLs in Technology Development
The Technology Readiness Levels framework offers several key advantages for both innovators and organizations:
a) Clear Roadmap for Development
TRLs provide a structured pathway, helping teams understand where their technology currently stands and what steps are needed to move forward. It helps avoid skipping crucial stages and ensures that the technology is fully tested at each phase.
b) Improved Communication with Stakeholders
Whether you’re seeking investment or working with development partners, TRLs provide a common language to describe the maturity of your technology. This helps manage expectations and communicate progress clearly.
c) Risk Management
By following the TRL framework, you can identify risks early in the process and address potential issues before advancing to the next level. This reduces the chances of costly failures later in development.
d) Informed Decision-Making
Understanding your technology’s readiness level allows for more informed decision-making regarding funding, resources, and timelines. It helps you determine when a technology is ready for market entry or needs further refinement.
4. Navigating the Transition from One TRL to the Next
Successfully advancing through the TRL stages requires careful planning, resource allocation, and collaboration between different teams. Here are some tips for managing transitions between TRLs:
a) TRL 1 to TRL 3: From Research to Proof-of-Concept
During these early stages, the focus is on research and experimentation. Work closely with R&D teams to explore the feasibility of the concept. Identify potential technical challenges early to guide future development.
b) TRL 4 to TRL 6: From Lab Validation to Real-World Testing
At this point, you’ll need to start building more functional prototypes and testing them in environments that reflect real-world use cases. Gather feedback from initial tests to refine your design and ensure that the technology can handle practical conditions.
c) TRL 7 to TRL 9: From Prototype to Market
As you approach the final stages, focus on rigorous testing, certification, and regulatory compliance. Ensure that your technology meets industry standards and is ready for commercialization. Collaborate with manufacturers, partners, and early adopters to prove the system’s operational reliability.
