Polaris Solar Photovoltaic News : Recently, the Cypriot government has successfully passed a 60.2 million euro national guarantee proposal (26 votes in the House of Representatives with 26 votes in favor and 23 votes against). The funds will come from the EU NER300 support plan and be used in Cyprus graphite tower 50MW solar thermal power project --EOS construction projects, and this is the fourth attempt Cyprus government on the adoption of the proposal.

As a matter of fact, the EOS project , the world's first graphite-based commercialized CSP plant , should have been officially put into operation in June this year, and the above-mentioned EU funding plan was announced publicly as early as 2014.

However, the domestic opposition party in Cyprus has been delaying and demanding further clarification, while other photovoltaic power plant operators are also protesting the state's use of the funds to support a private investor, which eventually led to the project being suspended for many years due to financing issues.

It is reported that the EOS project was approved by the Cypriot government as early as March 2014, and will be built in Alasa, Cyprus ’Limassol region. The technology used in this project comes from Australia's Solastor, a modular tower CSP technology using graphite as a heat transfer and heat storage working medium.

The developer of the project, Alfa Mediterranean Enterprises, plans to build 300 graphite tower CSP projects, resulting in a total installed Eos project of 50MW. After the project is completed, the annual power generation will be 172GWh, and the total investment is expected to reach 175 million euros.

▼ Modular tower CSP technology with graphite as heat transfer and storage medium:

The EOS project will use a three-meter-high working fluid tank on the top of a relatively low 20-meter-high heat-collection tower, which will be placed in the middle of the heliostat.

This steel working fluid tank stores high-purity graphite blocks, and stainless steel pipes are embedded in the graphite blocks, and hydraulic fluid is circulated inside. The thermal energy absorbed by graphite exchanges heat with the water in the steel pipe, heating the water to superheated steam, and driving the turbine to generate electricity. After the work is done, the steam is cooled to the next working cycle.

Graphite is an ideal working medium for high-temperature heat storage. Its maximum working temperature can reach 3500 degrees Celsius. Its high specific heat capacity allows it to store a large amount of thermal energy. High-purity graphite has a storage capacity of 300kWh / ton at 750 ° C and a storage capacity of 1000kWh / ton at 1800 ° C.

Based on its high-efficiency thermal insulation performance, Solarastor's CSP system does not require additional heat storage systems such as molten salt, and its heat collection system and heat storage system are integrated.

The single heliostat used in this technology is about 10 square meters, and the number of heliostats used in a single tower is 100 ~ 120 sets. This modular design is very suitable for uneven terrain in Cyprus. Each module can be distributed in different locations. The requirements on terrain are very low.

This photothermal power generation superheated steam generation system can generate electricity through the drive of a steam turbine, integrate it into the power grid or supply special power facilities, and can also provide thermal energy output for use in other thermal energy utilization fields such as industrial steam utilization.
