IEA 2050 road map
The Cyprus Institute
CSP plants will be the dominant technology in the future for Middle East and African countries and they will play a significate role in other regions
20/12/2017 The EOS CSP Green Energy project in Cyprus - NER300 meeting 2
The International Energy Agency predicts a bright
future for CSP: 11% of world energy needs in 2050
Up to 4.350 TWh by 2050 according to the hi-Ren scenario (Energy Technology Perspectives 2014), meaning CSP/STE will account for 11% of the electricity generated worldwide and 4% in Europe
From the quoted figures of IEA above the expected world energy that will be generated through CSP systems in 2050 requires 25.000 systems of the current size of Alassa! We are just at the beginning of a mammoth future …
Europe is responding: The agreed strategic European target in Solar Thermal Electricity that comes out of the Declaration of Intent is: Short-term: > 40% cost reduction by 2020 (from 2013) translating into Supply price < 10 c€/kWh for a radiation of 2050 kWh/m2/year (conditions in Southern Europe).
The good news is that the EOS technologies are already there and improving …

50 MW PROJECT - CYPRUS
The EOS (Green Energy) project at Alassa in Cyprus was proposed in June 2013 for a grant under the 2nd call of the NER300 program, that as we all know here, it offers grants to installations of innovative renewable energy projects. The project was successful in the application and has been granted the amount of €60.2 million after completing all due diligence procedures of the EC and EIB. The CSP plant is to be constructed in Cyprus with a total budget of €175 million.

CSP project of EOS / SOLASTOR in Cyprus
The project Alassa is a multi tower Concentrated Solar Power (CSP) system providing the annual electricity demand of more than 65.000 households.
The CSP power station consists of 2 main subsystems: 300 heliostat fields, each with individual control system
300 solar thermal receivers (STR) incl. storage and steam generation system and
1 conventional power block with high efficiency steam turbine of 50 MWe net capacity
The modular architecture, using a low height tower system (25 m) is highly suitable for hilly areas found in Cyprus or elsewhere in the Mediterranean
20/12/2017 The EOS CSP Green Energy project in Cyprus - NER300 meeting 5
Validation of technology
The EOS Green Energy project has gone through two independent due diligence processes and have successfully completed both with positive recommendations for the project. These were: European Commission and European Investment Bank for
constructing the project in Cyprus with total budget of €175 million and after the positive results has been granted the amount of €60.2 million.
FICHTNER GmbH & Co. KG of Germany after a formal application of Alfa Mediterranean Enterprises Ltd with the request of providing an independent review of the solar resource and the annual electricity production which have been calculated for the project by the developers.
20/12/2017 6 The EOS CSP Green Energy project in Cyprus - NER300 meeting
First of its kind in the Mediterranean
The project utilises new technology developed in Australia, which has built-in energy storage.
The project will be the first of its size and type in the entire Mediterranean basin and will feed electricity to the island’s grid.
Technology is already operated in demonstration plants in Australia and China
Most environmentally friendly and efficient CSP technology with storage, no heat transfer media as molten salt or synthetic oil, no risks for spillage or gas emissions
An important alternative to molten salt central receivers or parabolic trough
20/12/2017 7 The EOS CSP Green Energy project in Cyprus - NER300 meeting
Plant Concept - Simplicity Modular CSP system
Each module consists of:
Heliostat field
Tower including receiver, storage and steam generation in one package
Conventional plant technology
Feed water and steam piping
Steam turbine and generator
Electrical and control systems

Technology – Modular System
The EOS CSP Green Energy project in Cyprus - NER300 meeting
300 individual modules, each can yield 4.5 MWh thermal energy per day
Cavity receiver and graphite heat storage with embedded steam generation as core of each module
Fully engineered and certified package that is 100% factory made (no field works)
The system receives CE certification and complies to EC pressure equipment directive, highest quality standards are mandatory
Graphite is well known as material in high temperature applications
20/12/2017
Graphite as Thermal Energy Storage
Material
Graphite is an ideal medium for energy storage because of its high chemical stability and high heat storage capacity (1.75 kJ/kgK at 500°C)
Today’s technical storage capacity ranges is around 300kWhth per tonne at 750oC, but could go to about 1000kWhth per tonne at 1800oC.
Graphite can be heated from a solar system to very high temperatures
Graphite has high thermal conductivity, thus excellent heat transfer within a graphite module
20/12/2017 The EOS CSP Green Energy project in Cyprus - NER300 meeting 10
Energy Balance of 1 Module
Energy Captured into STR = 4.9 MWh/day
Storage Capacity of STR = 3.2 MWh/day
Throughput Capacity (24hrs) = 4.9 MWh/day
(at average DNI 6.5 kWh/m2/day)
24 HOUR OPERATION CAPABILITY

Land Requirements
Each module 65m x 35 m = 2300 sq metres
Allowance for access and piping between modules
= 2500 sq m very high field density due to multiple tower system
i.e. 4 modules per Ha (approx.), Power Block ~ 150 x 200 m
CYPRUS 1 PROJECT − 300 modules
LAND AREA(adding access) − 850,000 sq m (85 Ha)
ANNUAL OUTPUT − 185,000 MWh
PRODUCTIVITY = = 2,176 MWh/Ha/year
(This compares to about 1,000 to 1500 MWh/Ha/year for other CSP technologies and 1,900 MWh/Ha/year for PV without storage)

Thermal Power input comparison
The system’s high efficiency level is
due to five key factors
The high accuracy toroidal heliostat optimally arranged in small fields provide high annual field efficiency of over 70% since geometric as well as optical losses are very small
The energy concentration ratio of the toroidal mirrors to the STR is more than 1,000:1 and is delivered with pinpoint accuracy to the target.
Irradiation is focused on a down-facing cavity receiver, reflection and radiation loss are minimized
STR modules are thermally insulated, low heat losses from the storage
Steam production is at high temperatures and pressures which allows high steam turbine cycle efficiency

Electricity Market Study
Purpose of the study is to determine future wholesale electricity prices at Cyprus for the years 2020, 2030 and 2040.
The electricity prices are an important factor for the economic viability of renewable energy projects.
The strategic direction of the study is to provide an assessment of the expected market development based on technical facts and basic rules of energy economics
Where assumptions are needed, these are based on reliable sources, generally the more conservative numbers have been used

Parameters for modelling the electricity
prices The study of Fichtner aims at determining the future wholesale electricity
prices in Cyprus for the years 2020, 2030 and 2040 based on the development of
electricity demand
renewable energy sources
fuel types, fuel prices and CO2 prices
development of conventional power generation fleet (considering decommissioning and replacement/modernization of power plants, capacity increase to cover residual load (i.e. electricity demand not covered by renewable energies)
change in policies e.g. fuel switch due to stricter industrial regulations concerning emissions, potential deployment of LNG in the conventional power plant fleet
Change of energy market rules in Cyprus
Development of a market model which reflects all these parameters
The EOS CSP Green Energy project in Cyprus - NER300 meeting 20/12/2017
Results: Average wholesale electricity prices
2020 – 2025 Price increase due to fuel cost increase (low impact of RE on price)
2025 – 2030 RE start to reduce the overall price level; most inefficient conv. Units not price relevant any more
By 2030 Replacement of old conventional plants due to retirement necessary
2030 – 2040 Increased RE generation reduces price level, while fuel cost further increase
