The small solar thermal power plant is being developed
with funding from EU Horizon 2020 Program. The plant is
configured around a 2-kWel Organic Rankine Cycle turbine and
solar field, made of Fresnel mirrors. The solar field is used to
heat thermal oil to the temperature of about 240 oC. This
thermal energy is used to run the Organic Rankine Cycle turbine
and the heat rejected in its condenser (about 18-kWth) is
utilized for hot water production and living space heating.
The plant is equipped with a latent heat thermal storage to
extend its operation by about 4 hours during the evening
building occupancy period. The phase change material used is
Solar salt with the melting/solidification point at about 220 oC.
The total mass of the PCM is about 3,800 kg and the thermal
storage capacity is about 100 kWh. The operation of the plant
is monitored by a central controller unit. The main components
of the plant are being manufactured and laboratory tested with
the aim to assemble the plant at the demonstration site, located
in Catalonia, Spain. At the first stage of investigations the ORC
turbine will be directly integrated with the solar filed to evaluate
their joint performance. During the second stage of tests, the
Latent Heat Thermal Storage will be incorporated into the plant
and its performance during the charging and discharging
processes will be investigated. It is planned that the continuous
filed tests of the whole plant will be performed during the 2018-
2019 period.
