JRC coordinates 'SETIS', an Information System for strategic planning and priority setting in Strategic Energy Technologies:

• Implementation progress
• Global technology and market

developments

• Dissemination portal

https://setis.ec.europa.eu

Knowledge management for the EU Energy Union

Aim

• explore/illustrate use of densification (network theory

metric) to shed light into technology evolution Approach

• use JRC Tools for Innovation monitoring (TIM) software
• bibliometric & network analysis on Scopus publications

• JRC is developing TIM and building institutional

capacity in applications of text mining and network analysis for policy support

• Our network theory & bibliometric analysis results

provided potentially relevant metrics for gauging technological development stages

Final remarks – analysis

• Densification patterns for three renewable energy

technologies in line with their developmental stages

• Technology granularity levels and approach

potentially applicable to wider ranges of upcoming renewable energy technologies

Final remarks – results
