Infrastructure

The infrastructure is divided in four areas, three of them related to testing at different scales and one related to computing facilities:

1. Laboratory equipment
2. Test rigs
3. Pilot plants
4. Computation cluster

This infrastructure has allowed the group to carry out more than 15 international and 20 national research projects, and this has been and continues to be an attraction for many researchers who come to GREiA to carry out part of their research.
