IGeS WORLD srl proposes a Decarbonization Intervention in the Taranto Plant (Ex-ILVA).

Proposal for the Realization of Temporary Energy Source.

The plant is configured as a temporary installation of a Photovoltaic Plant meant to supply electricity from Renewable Energy sources (REN) for the production of hydrogen.

It is intended to convert the iron ore smelting process line for steel to systems that avoid the use of harmful coke and blast furnace. One of these is the direct reduction process line, or DRI – Direct Reduced Iron.


The temporary nature of the Plant would allow to supply hydrogen in a short time and partially satisfy the needs of the industrial plant while the construction of specific decentralized infrastructure for production and transportation are prepared; like the North African plants forecast by the Italian energy economists.


In this sense, the use of Green Hydrogen becomes economically sustainable during the phase of production, and satisfies the conditions of high availability of REN at zero distance from the site of use.

The project considers the installation of a Floating Photovoltaic Power Plant (FPV) on large surfaces of water mirrors. One hypothesis is to use the Mar Piccolo of Taranto as a host. A usable area of 4.5 sq. km is assumed for a net production capacity of 500 MW with a loading factor of 4000 hours.

The Plant could be divided into 5000 hubs of 100 kW, each one equipped with its own inverter and transformer. The power would be delivered to the ex-Ilva site with an offshore-onshore transmission line of approximately 10 km.

The 200 set of 2.5 MW electrolysers proposed would be located on the ex-ILVA industrial site, considering an hourly production of 500 Nm3 at a 32-bar pressure. The storage tanks could be sized for a cycle of 10 hours, for a capacity from 50 to 100,000 cubic meters. In this way it would be possible to ensure continuous supply to the generators with hydrogen turbines.

guardate l’ossigeno al suo fianco dormire”

look at the oxygen beside it sleeping.”

The Project name is TeSPI – Temporary Solar Park Installation, and recalls the name of the Greek Tragedian of the sixth century BC. In addition to the theatrical genre itself, Tespi also invented the traveling chariot with the same name, and completed it with scenes and orchestra to bring the representations all around Greece. In the following centuries, the chariot was intensively used to disseminate the culture of Tragedy and Comedy representation among the peripheral populations. Furthermore, during the difficult moments of the Nation, it was used to raise the soul energies of the depressed citizens who could not get close to the big cities during the Persian Wars first, or the Peloponnese-ones later.

Correspondingly, our TeSPI has a similar purpose, to supply large amounts of renewable energy to industrial sites that are undergoing a conversion path of sustainability – energy-intensive industrial infrastructures, which are close to the coast, such as refineries, cement factories, chemical industries. The reversibility of the installation is made possible by the recovery of all the anchoring panels and of the inverter-transformer hubs by lifting the ballast weights made of water-filled bags, or inflatable air cushions.
