Our Vision

In the HiFlex project, a pre-commercial power plant based on Concentrating Solar Power will be developed, built and tested at a pasta plant in Italy.
The EU co-funded project will demonstrate, that it is possible to run the plant 24/7 and continuously generate renewable energy.

Barilla, one of the leading pasta producers worldwide, can use the thermal energy for its pasta production in order to partly reduce its consumption of fossil fuels.

Technology

A solar power plant with storage for
the supply of flexible energy.

Concentrating Solar Power

Concentrating Solar Power (CSP) systems use mirrors to focus sunlight on a small spot, where a absorber medium gets heated. The absorbed heat can be directly used to generate electricity, process heat or stored for later use.

Heliostats

Heliostats are movable mirrors, which reflect sunlight to the top of a tower. Computers control the heliostats to ensure their proper and correct alignment according to the movement of the sun during the day. In HiFlex, a heliostat field will be developed and built with special focus on cost reduction and improved manufacturing

Solid particle systems and Particle receiver

Solid particle systems are considered a promising option for future CSP. Small ceramic particles are used as absorber and storage medium. Temperatures up to 1000°C are possible due to the direct absorption concept and advantageous particle properties. Unlike state-of-the-art molten salt, the particle system does not experience the danger of fluid freezing and thus does not need any trace heating. The low cost of the particles and the significantly reduced need for high-temperature metallic alloys lead to lower receiver and storage costs.

In the HiFlex project, solarradiation is concentrated onto a so-called Centrifugal Particle Receiver (CentRecÒ) with 2.5 MW peak thermal power which is mounted on top of the tower. Small ceramic particles as the absorber medium passes through the receiver and get thereby heated up to 1000°C. The basic concept of the receiver is a rotating cylinder with an inclined rotation axis. Particles are fed into the receiver and forced against the inner cylinder wall by centrifugal forces, where they form a thin, but optically dense particle film. While slowly moving along the wall towards the receiver outlet, the film is gradually heated by incoming solar radiation.

Electric particle heater & Backup heater

In times, when there is not enough direct radiation for CSP available or the increasing share of photovoltaic (PV) and wind energy leads to excess power in the grid, an electric particle heater (100 kWel) is employed to heat up the particles with PV or wind electricity. This avoids curtailment of renewable power systems and enables further increase of PV and wind capacity. In this way, the HiFlex system can act in a controlled manner both as power supply as well as power sink, and thus contribute to grid balancing with positive and negative power.

On cloudy and windless days however,a simple burner for renewable fuel (800 kWth), like biogas, cellulosic ethanol or renewable hydrogen, is foreseen to heat up the particles, ensuring the full production capacity for grid stability. This feature avoids the need to keep other conventional power blocks in stand-by that would only be used for a limited number of hours during the year. Due to the limited usage of this feature the total amount of renewable fuel is expected to be quite small (< 5%).

High density storage

The heated particles can be directly stored in an insulated tank for later use, allowing the generation of dispatchable power. Due to the large temperature span from 300°C to 700°C between hot and cold state of the particles the volumetric storage density is about 2.5 times higher than current solutions. Together with low cost particles this results in reduced specific storage costs (about 50% of current solutions).

After passing the steam generator, the cooled particles are stored in a second tank. Both tanks are sized large enough to smooth out the variable energy inputs.

icons / 30 / a-icon-plus-default Created with Sketch.

Steam generator & turbine

In order to generate steam for power production the heated particles are led through the steam generator.

The high driving temperature difference in the steam generator results in a low heat transfer area and smaller units with reduced thermal inertia. Therefore, a faster ramping of the power cycle is allowed which improves the response to grid demand fluctuations.

Depending on the demand of the energy user, high temperature, high pressure steam is produced from the hot particles and subsequently converted to electricity with a steam turbine. If low temperature heat is needed, the steam is not expanded completely, but extracted from the steam turbine at a sufficient temperature. This combined heat and power scheme allows the use of waste heat coming from the turbine. In the actual HiFlex project however, the steam turbine is left out as it is state-of-the art technology.

Particle transport

The particle transport from the cold storage tank to the receiver inlet is done batchwise in insulated containers with an elevator system, incorporating a small heat losing surface. For the short distance from receiver outlet to hot storage an insulated pipe with a gravity driven transport of the hot particles is foreseen.

Grid

The electricity produced using renewable sources is provided to the power grid. The HiFlex system is able to deliver secure electricity on demand. Due to the included storage system it is moreover capable of providing flexibility to the grid. It can either function as a power source or a power sink.

icons / 30 / a-icon-plus-default Created with Sketch.

Pasta Production

The HiFlex system is intended for continuous operation over a period of 18 months. The partner Barilla is especially interested in a future combined heat and power (CHP) application. Preliminary cost estimations for the Barilla production site near Foggia, South Italy, indicate attractive cost for both, electricity and heat production, and CO2 reductions for the pasta production. Barilla is therefore interested to have the demonstration system installed on their premises, allowing the integration of process heat from the pre-commercial HiFlex system into the existing pasta production and learning about the operation and economics of the system.

Life Cycle Assessment

The environmental performance of the HiFlex system will be assessed by means of an environmental life cycle assessment (LCA). It will focus on impact categories like greenhouse gas emissions (carbon footprint), non-renewable primary energy use (energy footprint), water use (water footprint) and land use, as well as on impacts on ecosystems and human health.

Our partners

The pan-European consortium of HiFlex brings together internationally recognized experts from eachtargeted development area, with the aim to leverage their complementary skills to fully cover all development aspects of the high temperature particle CSP concept. Together they will demonstrate the technical and economic feasibility of the HiFlex system and its potential to considerably contribute to carbon emission reduction.
