The fourth Coordiantion Meeting of LIFE NEXUS was held on 22th April, 2021. Due to the Covid-19 pandemic, the meeting was telematics and was attended by the entire consortium together with the external monitor, Mrs. Cristina Vicente Álvarez, from IDOM-NEEMO.

The main advances carried out during the previous year were presented. On the one hand, the European inventory of potential mini-hydro energy recovery locations has continued to grow and currently houses data from 101 facilities from 10 European countries.

In addition, the work carried out in the demonstrator of the drinking water treatment plant of the city of Leon in Spain was presented. Once the micro-hydraulic generation prototype (pump working as a turbine and battery storage) has been desgined and the tender for its construction has been awarded, it is awaiting the approval of the building license. Once this permit has been given, the construction, legalization and commissioning works will begin, so that the turbine will be in operation by the end of 2021.

Finally, the 18 ongoing replication studies on potential and existing energy recovery locations in Spain, Lithuania and Poland were described.
