During the last week of February, a group of researchers from the Josip Juraj Strossmayer University of Osijek (Croatia) visited the Renewable Energy Research Institute as part of the European University Alliance COLOURS, to which both UCLM and the aforementioned university are affiliated. During their visit, they toured the laboratories and facilities of the Grid Energy Integration section and the Biomass section. Due to the synergies found with the latter, the researchers expressed great interest in establishing research collaborations and promoting the joint application for European or international projects.
