Key Concepts Explained
Cleantech (Clean Technology)
Cleantech refers to technologies that reduce environmental impact, improve sustainability, and promote efficient use of resources. Examples include renewable energy systems, smart devices, and advanced materials.
Technology Readiness Level (TRL 2–6)
TRL indicates how developed a technology is:
- TRL 2–3: Concept and proof of concept
- TRL 4–5: Lab validation and early prototype
- TRL 6: Prototype tested in relevant environment
The program targets innovations that are beyond idea stage but not yet fully commercialized.
Defensible Intellectual Property
This refers to technologies protected by patents (issued or pending), ensuring competitive advantage and preventing easy replication.
