Query: BIOSTIRLING-4SKA : A cost effective and efficient approach for a new
  generation of solar dish-Stirling plants based on storage and hybridization;
  An Energy demo project for Large Scale Infrastructures",   The BIOSTIRLING - 4SKA (B4S) is a EU demonstration project dealing with the
implementation of a cost-effective and efficient new generation of solar
dish-Stirling plants based on hybridization and efficient storage at the
industrial scale. The main goal of the B4S demonstration project is the
generation of electric power using simultaneously solar power and gas to supply
an isolated system and act as a scalable example of potential power supply for
many infrastructures, including future sustainable large scientific
infrastructures. B4S build an interdisciplinary approach to address
reliability, maintainability and costs of this technology. In April 2017, B4S
successfully tested in Portugal the first world Stirling hybrid system
providing about 4kW of power to a phased array of antennas, overcoming
challenges in Stirling and hybridization and smartgrid technologies. B4SKA
Consortium, with fourteen companies from six European countries, has performed
the engineering, construction, assembly and experimental exploitation, under
contract signed with the European to develop on off-grid demonstrator in
Contenda (Moura) Portugal.
