The POLYPHEM project is a research and innovation action funded by the European Union's H2020 program. It is implemented by a European consortium of 4 research centres and 5 industrial partners. The aim is to increase the flexibility and improve the performance of small solar tower power plants. The concept of POLYPHEM consists in implementing a combined cycle formed by a solarized micro gas-turbine and a Rankine organic cycle machine, with an integrated thermal storage device between the two cycles. The need for cooling is minimal.

Developed from a patented technology by CNRS and CEA, the pressurized air solar receiver is integrated in the micro-turbine cycle. The thermal efficiency targeted for the receiver is 80% with a cost of 400 €/kW. The innovative thermal storage uses a thermal oil and a single thermocline tank with a technical concrete filler material.

The main expected impact of this project is to enhance the competitiveness of low-carbon energy production systems through the technology developed. The expected progress is a better fitting of electricity generation to variable local needs, an overall conversion efficiency of solar energy into electricity of 18% for an investment cost of less than 5 €/W and a low environmental impact. By 2030, the cost of electricity production targeted by the POLYPHEM technology is 165 €/MWh for an annual direct normal irradiation of 2600 kWh/m²/year (North Africa and Middle East) and 209 €/MWh under 2050 kWh/m²/year (Southern Europe). In addition to decentralized power generation, other applications are considered for the deployment of this technology used in poly-generation: industrial heat production, solar heating and cooling, desalination of seawater or brackish water.

A prototype plant of 60 kWel with a thermal storage of 2500 kWh is designed, built and installed on the site of the experimental solar tower of Themis in Targasonne (France). The objective of the project is to validate the technical choices under test conditions representative of actual operating conditions.

# 1. INTRODUCTION

The general engineering presented in this deliverable consists in all the engineering (hydraulic, electrical ...) needed for the construction of plant.

Some issues during the final step of the construction of the solar receiver in summer 2021 yielded a modification of the P&ID and consequently a modification of the prototype plant to be constructed and operated at Themis site.

Please note that this deliverable refers to two plant designs: the POLYPHEM plant featuring the solar receiver, the gas-turbine, the TES and the ORC, called "Initial design", and to the prototype plant as it is actually realized, called "Final design".

# 2. ENGINEERING OF POLYPHEM PLANT: INITIAL DESIGN

## 2.1 ENGINEERING OF THE MAIN COMPONENTS

The detailed engineering of the main components of the POLYPHEM plant was carried out by the partners in charge of the construction and of the delivery of the related components.

The detailed engineering of the ORC was carried out by ORCAN. It is presented in the deliverable D2.5 "Report on the design of the modified ORC system" issued on 03/06/2020.

## 2.2 ENGINEERING OF THE THERMAL OIL LOOP

### 2.2.1 Initial version of plant layout

POLYPHEM is composed of the air circuit and of the thermal oil circuit. The air circuit comprises the gas-turbine (GT) and the solar receiver (SR), and the thermal oil circuit comprises the thermal energy storage system (TES) and the organic Rankine cycle (ORC). Both circuits are interfaced with the recovery heat exchanger (RHX). The general layout of POLYPHEM plant was initially created by the consortium and was presented in the deliverable D4.1 "Report on the Overall Plant Layout" issued on 10/02/2020. In this layout of the plant, the air circuit is located at the top of the solar tower. The RHX transfers the exhaust heat to a closed loop of thermal oil at high pressure located in the tower. The oil circuit at ambient pressure is located on the ground and is interfaced with the pressurized oil loop through a heat exchanger (oil HP/oil LP). The P&ID associated to this layout is presented in Figure 1.

### 2.2.1.1 Hydraulic and thermal simulation

The Fraunhofer ISE simulated the loops in various operating modes using Ebsilon® software tool, assuming a rough set of dimensions for the pipes. The simulation work is reported in the deliverable D4.1 "Report on the Overall Plant Layout" issued on 10/02/2020. For example, the results for the TES charging and discharging are presented in Figure 2 and Figure 3, respectively.

<figure><img src="image_7.png" /><figcaption>Figure 3: POLYPHEM plant: TES discharging</figcaption></figure>

### 2.2.1.2 Technical specifications

The design values for the primary and secondary oil loops are issued from the simulation work carried out by Fraunhofer ISE and are summarized in Table 1.

### 2.2.2 Revised version of plant layout

The detailed engineering of the thermal oil circuit was sub-contracted by CNRS to an external engineering company. The company carried out the following studies:

* Hydraulic and thermal engineering

* 2D/3D Plans

* Electrical engineering

* Assistance for the tender and selection of offers for the construction and delivery of the thermal oil loop.

The detailed engineering of the TES tank imposed some major constraints. In particular, the sealing of the top cover cannot guarantee the perfect tightness. Consequently, it was agreed that the TES is open to the air (at atmospheric pressure) and serves as expansion vessel. The heat exchanger at the bottom of the tower to separate HP and LP oil circuits was skipped, due to the high cost of construction of this component. A single thermal oil circuit was therefore proposed. However, a regulatory pressure valve was installed at the bottom of the tower, to prevent the TES tank to be exposed to a high pressure resulting from the difference of temperature between the hot down-coming pipe and the cold up-coming pipe. The P&ID of the thermal oil circuit was modified accordingly.

The revised P&ID was presented in the deliverable D6.1 "Measurement techniques and experimental protocols for the testing and evaluation of the prototype of plant" issued on 19/05/2022, at page 10/41. This P&ID is presented in Figure 5.

### 2.2.2.2 Container

The main thermal process will be installed in a prefabricated maritime container (size 20"), to protect the equipment against bad weather conditions and to facilitate the collection of thermal oil in case of leakage. The container will be positioned on a specially adapted foundation.

It includes:

- Access doors

- Internal supports

- Metallic frit licker

- Inside and outside lighting

- Alarm indicator (3 colors)

### 2.2.2.3 Electrical heater

The consortium decided to implement an alternative heat source in the thermal oil circuit, to be used when solar resource is not available, or in case of failure of the solar receiver, or to be able to operate separately and independently the air circuit and the thermal oil circuit.

The subcontractor proposed an electrical heater manufactured by CETAL with a specification of 312 kW.

Rough dimensions:

<table><thead><tr><th></th><th>Heater</th><th>Electrical Cabinet</th></tr></thead><tbody><tr><th>Dimension (L x W x H)</th><td>3 m x 0,8 m x 0,6 m</td><td>2 m x 1,6 m x 0,6 m</td></tr><tr><th>Weight (kg)</th><td>500 kg</td><td>750 kg</td></tr></tbody></table>

### 2.2.2.4 Size of pipes

The thermal specifications were conserved unchanged. Two levels of temperature were considered: 15°C and 323°C. The influence of the size of the oil pipes on the pressure loss was analysed. To this end, the subcontractor carried out simulation work of the thermal oil flow using the software Comsol Multiphysics® and the module "PipeFlow". The length of pipes has been assessed in the revised version of the plant layout and it was kept constant, whereas the diameter of pipes was varied, from DN25 to DN50. The simulated results are presented in Figure 6, Figure 7, Figure 8 and Figure 9.

From these technical results and considering the cost figures, the dimension DN25 was selected for the oil pipes.

All the piping will be made of seamless drawn black steel pipe, used at high temperatures, with smooth ends, according to the NF A 49-211 standard. The steel grade is P265GH.

Welded assemblies are preferred to limit the risk of leakage. At the interfaces with the equipment, single interlocking flanges with stainless steel spiral graphite gaskets should be used. Piping tests will not be performed with water but with nitrogen. The prefabricated elements intended to equip the tower will not exceed a unit length of 6 meters.

All devices (such as circulation pumps, exchangers, control devices, etc.) must be able to be isolated from the rest of the circuit. The isolation on the inlet and outlet will allow the draining, purging, dismantling or removal of the equipment for repair, cleaning or replacement, without complete emptying of the installation. The name and number of the equipment will be marked with a medal on a chain or riveted near the device concerned.

### 2.2.2.8 Thermal energy storage tank and Expansion vessel

ARRAELA brought some modifications to the tank design in order to comply with the construction constraints. In particular, the cylindrical geometry of the tank has been replaced by a dodecagonal geometry. Significant efforts were dedicated to the engineering of the formworks, of the top cover, and of the HTF pipes and diffusers. Electrical heaters have been incorporated into the tank to preheat the HTF in the commissioning step under cold weather conditions, or after a long interruption of operation. The thermal energy storage tank (TES) is at atmospheric pressure. It serves as expansion vessel for the thermal oil circuit. A sufficient volume is left above the upper diffuser to accommodate the volume needed by the thermal expansion of the oil. A radar level gauge is installed in the upper part of the storage tank. This gauge measures and transmits the fluid level, which must remain permanently above the upper diffuser. The maximum measuring range is 1 meter. The resulting design of the thermal energy storage tank is presented in Figure 10 and Figure 11. The tank is equipped with 80 thermocouples to measure the distribution of temperature of the oil and of the walls. The thermocouples are represented by red bullets in the drawing of Figure 10 and Figure 11.
<figure><img src="image_14.png" /><figcaption>Figure 10: Vertical cross section of the thermal energy storage tank</figcaption></figure>
<figure><img src="image_15.png" /><figcaption>Figure 11: Horizontal cross-section of the thermal energy storage tank</figcaption></figure>

When the oil circuit and all the components (RHX, ORC and TES tank) are filled with thermal oil, or heat transfer fluid (HTF), the total volume occupied is 7669 l. The TES tank contains 7200 l, while the rest of the circuit contains 469 l. When the HTF is heated from 0°C up to 350°C (maximum heating), the variation of density (from 1059 kg/m3 at 0°C to 799 kg/m3 at 350°C) yields a variation of volume of 2495 l. An additional volume is left at the top of the TES tank to accommodate this thermal expansion of HTF.

The mass of HFT in operation, referred to the temperature of 0°C, is 8121 kg. In practice, 9780 kg of thermal oil was delivered on site for the need of POLYPHEM on 04/04/2022. The surplus allows modifications of the circuits or of the components.

The mass of filler bricks stacked in the TES tank is 22765 kg.

The main physical parameters of the TES system are summarized in Table 3.

### 2.2.2.9 Thermal oil storage tank ST-200

The thermal oil is stored in a tank which is located beneath the circuits. The oil is pumped out of this tank to fill-in the circuits. When the circuits are drained, the oil is collected and directed back to the storage tank by gravity.

<footnote>(*) Derived from deliverable D3.4 “Report on the lab-test of the thermocline storage system” issued on 16/02/2022.</footnote>
The storage tank must have a double wall to avoid leakage of oil in the environment, and it must be able to accommodate the 330°C fluid in case of emergency draining. The tank will be hydrostatically tested on site and carefully dried.

<figure><img src="image_17.png" /><figcaption>Figure 13: Power supply of turbine and lubrication cabinets</figcaption></figure>
The bottom electrical cabinet on the ground level, called “THEMIS” with 1000 A capability, supplies the top cabinet at 83 m through a “Reverser” of 800 A capability. Finally, this top cabinet dispatches the power over the “Turbine” cabinet and the “Lubrication” cabinet at 79 m according to the plan presented in Figure 13. CNRS “Sensors” cabinet at 79m is supplied from another existing cabinet at 75m.

### 2.2.3.2 Bottom of tower

The bottom electrical cabinet on the ground level, called “THEMIS” with 1000 A capability, supplies the “POLYPHEM” cabinet located outside on the ground near the thermal process. Equipment in orange do not exist and need to be bought and created/fabricated. Equipment in blue exist already. All electrical cables do not exist and need to be installed at the Themis site.

<figure><img src="image_18.png" /><figcaption>Figure 14: Electrical connections – Bottom tower (blue: existing equipment)</figcaption></figure>

The electrical "POLYPHEM" cabinet dispatches power to:

- electric heater control cabinet: 400V 50Hz

## 3. ENGINEERING OF THE PROTOTYPE PLANT: FINAL DESIGN

In August 2021, the consortium of the project decided to cancel the installation of the solar receiver at the Themis site. The reason for this decision is a major failure in the manufacturing process of the receiver. This sequence is reported in the deliverable D5.2 "Manufacturing and installation of the solar receiver" issued on 11/01/2022. Eventually, the prototype plant erected in Themis slightly differs from the POLYPHEM plant initially designed, and it will be operated off-sun. The consortium also decided to cancel the installation of the gas-turbine at Themis site, since the operation of this component in fuel mode has already been demonstrated in the test facility of KAEFER. This demonstration was reported in the deliverable D2.7. "Demonstrator on the factory pre-test of gas turbine package and ORC module" issued on 17/05/2022.

In practice, the test program will be restricted to the testing of the RHX, the TES system and the ORC. The engineering of the prototype plant was again modified to be suited to the work plan. The gas turbine is substituted by a combustor, the electrical heater is skipped, the oil circuit in the tower is skipped. The combustor delivers hot gas at atmospheric pressure, it simulates the exhaust of the gas-turbine. The RHX is unchanged. All the components are installed at the bottom of the tower.

### 3.1 FINAL P&ID

The final P&ID is presented in Figure 17.

### 3.2 PLANT LAYOUT

3D and 2D plans of the POLYPHEM plant have been established. The plans are presented in Figure 18.

The RHX and the thermal oil circuit are installed in a container. The oil tank is placed on the ground near the container. The container is placed on two concrete supports. The combustor is installed on the roof of the container. The TES tank and the ORC group are installed on a platform near the container. The platform is surrounded by a small wall, making a retention tank which can collect and contain all the oil in case of leakage, thus avoiding any pollution of the environment. The components are placed at different levels, so the draining is obtained by gravity.

## 3.3 EQUIPMENT

### 3.3.1 Combustor

The combustor was designed, assembled and delivered by AALBORG CSP. It is made of a burner associated to an air fan. The burner provides a very hot gas flow, which is mixed and diluted in a cold annular air flow delivered by the air fan. The flow of dilution air is regulated by the rotation speed of the air fan to obtain the targeted temperature at the outlet of the combustor, in the range 180°C-495°C. The design of the combustor is presented in Figure 20.

The burner is the model WL40Z-A supplied by Weishaupt. It is shown in Figure 19. It burns domestic fuel, supplied from an existing fuel tank installed at Themis near the container. The range of thermal power is extended from 140 kW to 570 kW. Two nozzles are used, resulting in two values of operating power. For the need of POLYPHEM, the thermal power is set to 145 kW (1 nozzle, part load) or 330 kW (2 nozzles, full load).

<figure><img src="image_30.png" /></figure>

Example: WL30/WL40, version LN (Low NOx)

<caption>Figure 19: Burner Weishaupt WL30/WL40</caption>

The air fan is supplied by Hoyer. The rotation speed of the fan is regulated by a Danfoss frequency converter. The design dilution air mass flow of 0.82 kg/s is expected with a frequency of 50 Hz and outdoor temperature of 15°C. The maximum frequency admitted by the fan is 55 Hz.

<figure><img src="image_32.png" /><figcaption>Figure 21: Layout of the air circuit (combustor, by-pass valve, RHX and exhaust)</figcaption></figure>
### 3.3.1.1 Layout of the air circuit

The layout was designed by CNRS. It is shown in the drawing of Figure 21. The combustor is placed on the roof of the container. It is mounted onto reinforcement beams transverse to the roof. The burner and the air fan are located inside a shelter. The fuel is supplied by a duct from the fuel tank to the burner. The suction of fuel is made by the fuel pump of the burner, with a maximum capacity of 350 mbar. The combustor outlet is made of a bellow which accommodates the thermal expansion. It is connected to the EV-Air (by-pass valve) which directs the air flow to the RHX or directly to the exhaust. The bellow, the by-pass valve and the RHX are located inside the container.

### 3.3.1.2 Power supply and control of the burner

The diagram of the electrical interface of the burner is presented in Figure 23.

Terminals T1 and T2 (B15) are the “ON/OFF” of the burner. These terminals are remotely controlled by a 24 VDC digital output coming from CNRS control cabinet. When 24 VDC is sent, the burner is activated. When 0 VDC is present, the burner is deactivated.

Terminals T6, T7, T8 are responsible for the 2 operating modes of the burner, part load and full load. A rotative button disposed in front of the cabinet controls the operating mode. Half charge corresponds to T6 and T8 connected, full charge corresponds to T6 and T7 connected.

The combustion manager (W-FM25) is permanently supplied in 220 VAC. The line is protected by a 6 A circuit breaker.

## 3.3.2 Recovery Heat Exchanger (RHX-AA-01)

The RHX has been specially designed by AALBORG CSP for the needs of POLYPHEM. It is a shell and tubes heat exchanger. Two venting valves were added at the inlet and outlet of thermal oil before the RHX was delivered on site. The plan is presented in Figure 24.

### 3.3.3 Expansion vessel (VE-01)

The construction of the TES tank was delayed for about 6 months because of the COVID-19 sanitary situation. The TES tank serves as thermal expansion vessel of the oil circuit. The consortium decided to integrate a small expansion vessel of capacity 360 l, in order to allow the commissioning and testing of the oil circuit before the completion of the construction of the TES tank. The small expansion vessel is a horizontal cylinder 120 cm in length 120 cm and 60 cm in diameter. It is installed besides the combustor on the roof of the container. The maximal temperature of utilization is 393°C. It is shown in Figure 22.

The recirculation pump P-ORC is manufactured by KSB under the reference is Etanorm SYT. The total head is 20 m. The maximum mass flow is 16 m³/h. The suction pipe is DN50 and head pipe is in DN 32.

### 3.3.10 Frequency converters

The 3 pumps of the thermal oil circuit and the air fan for the dilution air of the combustor are controlled with frequency converters, manufactured by KSB and by Danfoss, respectively.

#### 3.3.10.1 KSB

The 3 frequency converters manufactured by KSB control the oil pumps. They are of same technology. The only difference is the power output for each one.

In "Automatic mode", the frequency drive is remotely controlled by CNRS with a 4-20 mA command signal.

In "Local mode", the velocity of the pump is set through the digital interface of the frequency drive.

#### 3.3.10.2 Danfoss

The Danfoss frequency converter controls the air fan for the dilution air of the combustor. In "Automatic mode", the frequency drive is remotely controlled by CNRS with a 4-20 mA command signal.

In "Local mode", the velocity of the fan is set through the digital interface of the frequency drive.

### 3.3.11 Cameras

Two cameras "TRENDnet TV-IP1318PI" are installed at Themis site in order to visualize the prototype plant POLYPHEM. The cameras are connected to the local digital network. The data (video records) are saved on a NAS and can be viewed in case of failure of process to facilitate the understanding of the incident.

Samples of images delivered by the cameras are presented in Figure 26 (camera #1) and Figure 27 (camera #2).

## 3.4 ELECTRICAL NETWORK

The technical specifications for the electrical network are summarized in the diagram of Figure 28.

## 3.5 DIGITAL NETWORK

The digital network was realized by CNRS in order to ensure the transfer of data and information between all the equipment connected to this network, in the prototype plant located at the bottom of the tower and in the control room located in a separate building. The digital network is presented in the diagram of Figure 29. The network is organized with two VLANs. A specific IP is allocated to each component.
