Technology Readiness Levels

Understanding Technology Readiness Levels (TRL)

In the realm of innovation, the Technology Readiness Level (TRL) serves as a pivotal gauge of a technology's development stage and its readiness for practical application. Embraced within the IEA's Innovation Gaps framework, the TRL scale delineates the evolution of a technology solution from its conceptualization to its full-scale deployment.

Each stage represents a significant milestone in the technology's journey towards practical implementation. These assessments provide insights into the progress and readiness of various technologies within the AFC TCP's purview, guiding stakeholders in strategic decision-making and resource allocation.

Breakdown

TRL Stages

Initial Idea

Fundamental principles are conceptualized.
1
2

Application Formulated

Concept and application of the solution are articulated.

Concept Needs Validation

The solution requires prototyping and practical validation.
3
4

Early Prototype

A prototype is validated under controlled test conditions.

Large Prototype

Components are validated under conditions mimicking real-world deployment.
5
6

Full Prototype at Scale

Prototype is validated at scale, ready for deployment.

Pre-Commercial Demonstration

Solution operates in expected conditions, nearing commercial viability.
7
8

First-of-a-Kind Commercial
