Italy's Solar Thermal Legacy

Historical and Modern Achievements in CSP

Italy has been at the forefront of solar thermal technology for over a decade. The Archimede plant, inaugurated in 2010, was the first CSP demo plant in Italy to utilize molten salt for heat transfer and storage in a parabolic trough system. This pioneering project set the stage for future advancements in the field.

In recent years, Italy has continued to lead the way with the commissioning of its first commercial CSP plant and several others in advanced stages of construction. This blend of historical innovation and modern progress makes Italy a fitting host for the 30th SolarPACES Conference, where tradition and cutting-edge technology converge.

Innovative Thermodynamic Solutions: effective and efficient coupling of CSP and desalination technologies

Innovative Thermodynamic Solutions: effective and efficient coupling of CSP and desalination technologies

Discover our groundbreaking work over the past year in advancing CO2 mixtures for thermodynamic cycles, pushing the boundaries of energy efficiency and sustainability.

The research team from the Energy Department at Politecnico di Milano (POLIMI), DESOLINATION project coordinator, has successfully simulated large-scale Concentrated Solar Power (CSP) plants using innovative CO2 mixtures, enhancing their efficiency and performance. Additionally, they introduced the CO2+SiCl4 mixture in literature for trans-critical cycles, showcasing its potential in improving cycle efficiency.

Our Journey in Thermodynamic Cycle Development

Over the past year, POLIMI has made significant strides in the development and simulation of thermodynamic cycles using CO2 mixtures. Here are some of the key milestones and achievements.

Introduction of CO2+SiCl4 Mixture Research

Introducing the CO2+SiCl4 mixture into the literature for transcritical cycles

With regard to the application of CO2 mixtures in thermodynamic cycles, the work was developed both on the simulation of the large-scale CSP plant with innovative CO2 mixtures, introducing the CO2+SiCl4 mixture into the literature for transcritical cycles, and adding details on the simulations and design of the DESOLINATION project’s demonstration plant, the 1.8 MWel cycle operating with the CO2+SO2 mixture.

Simulation of the large scale CSP plant with CO2+SiCl4 mixture

POLIMI combined CSP with CO2-mixtures power cycles and forward osmosis desalination system, performing simulations in Dubai.

Using these innovative technologies, our CSP plant showed high solar-to-electric efficiencies (around 19% on yearly basis) and very low freshwater specific thermal consumption (about 10 kWhth/m3) when the PABG2000 is used as draw agent.

Specifically, when comparing the CSP (concentrated solar power) +FO (forward osmosis) studied in DESOLINATION with the CSP+MED assuming the same solar plant and power cycles, the freshwater production is incremented by more than 50%.

When the solution of DESOLINATION is compared with a PV+RO plant, a reduction of reflective area of 28% is foreseen, if both freshwater and electricity are produced with the PV+RO plant.

Finally, POLIMI also conducted an experimental campaign on the coalescer using a solution of water and PAGB2000, obtaining an expression of the separation efficiency, to be deployed in the simulations.

The research team from the Energy Department at Politecnico di Milano will shortly be publishing an article on the results of its Experimental study on coalescer efficiency for liquid-liquid separation.

Commercial thermo-responsive polyalkylene glycols as draw agents in forward osmosis

Commercial thermo-responsive polyalkylene glycols as draw agents in forward osmosis

Forward osmosis (FO) is a promising technology for efficient water reclamation at low operating costs. It has shown potential in producing fresh water from seawater; however, the regeneration of the diluted draw solution (DS) still holds back further development. Thermo-responsive polymers, especially polyalkylene glycol (PAG) based copolymers with hydrophilic ethylene oxide and hydrophobic propylene oxide units, have shown suitability as DSs in FO using low-temperature waste heat to regenerate the DS. In this study, we explored five commercially available copolymers: Pluronic® PE 6400, Pluronic® L-35, Pluronic® RPE 1740, Unilube® 50 MB-26, and Polycerin® 55GI-2601 as DSs in a laboratory FO setup, with DI water as the feed solution (FS). The water
flux and reverse solute flux varied from 1.5 to 2.0 L⋅m􀀀 2⋅h􀀀 1 and from 0.04 to 0.4 g⋅m􀀀 2⋅h􀀀 1, respectively.

Furthermore, all polymer solutions showed the ability to be recovered and reused using temperatures below 100◦C. Therefore, the tested PAGs turned out to be promising as draw solutions for FO systems that utilize low-grade waste heat. The re-usage in FO was shown for regenerated Pluronic® L-35 through a three-step experiment where its recovery was 91.1 %, 93.1 %, and 91.9 % for each FO cycle, respectively.

Keywords: Forward osmosis, Draw solution, Osmotic pressure, Polyalkylene glycols, Lower critical, solution temperature, Reuse of polymer.
