Temporary renewable energy on 78.5 GW of electricity in 2030

Le rinnovabili flottanti a 78,5 Gigawatt di potenza nel 2030

floating renewable energy they can reach 2030. About 80 GW of electricity between wind and photovoltaics in, This is the figure around which we discussed in the Free Coordination Conference ‘Floating Renewables – Innovative Solutions for Renewable Sources: Photovoltaic and Floating Wind Power’.

Coordinamento Free (Renewable Sources and Energy Efficiency) is one such association that currently brings together a wide range of entities, along with 24 other associations. Free coordination aims to promote the development of renewable energy and energy efficiency within the framework of an environmentally sustainable social and economic model, decarbonization of the economy and reduction of emissions.

An actual seminar organized by Coordinamento Free was an actual seminar with the idea of ​​providing competent authorities to develop an analysis on the opportunities and growth potential of these technical solutions.

Floating renewable, photovoltaic and wind power

It is these technologies that allow, in the case of wind power, to be achieved in Italy. offshore plantsis otherwise prevented by the depth of the Italian sea floor, whereas in the case of photovoltaic Hydropower allows to exploit the wide availability of free surfaces in basins and reservoirs.

The Global Wind Energy Council expects 16.5 GW of floating wind capacity to be installed globally in 2030. On the same date, offshore wind potential in the Italian seas, estimated by ANEVE (National Wind Energy Association), begins with current and projected technologies. is 5.5 gigawatts. However, the global capacity of floating photovoltaics will reach 62 GW in 2030, according to expert assessments reported by Solar Energy Europe.

For the Italian power sector – it is explained – the new European REPowerEU plan translates into a target of increasing power to 85 gigawatts of renewable energy by 2030 which will allow us to reach 84% renewable energy in the electricity mix. For Italy, accelerating renewable energy in line with REPowerEU 2030 benefits the economy, society and the environment.

We are talking about 309 billion cumulative investments by 2030 in the power sector and its industrial supply chain, 345 billion cumulative economic benefits by 2030 in terms of value added by the supply chain and driven, and an increase in national consumption, 470 thousand new jobs. are. supply chain and in the electricity sector in 2030 (which will increase to about 120,000 today) and a 75% reduction in CO2 emissions from the power sector in 2030 compared to 1990.

Among the fundamental measures to move forward on this front, an amendment to the Bolet decree was approved by the Faciamoisco deputy Rossella Muroni in the Chamber’s Environment Committee which provides “Simplified authorization procedure for the construction and operation of floating photovoltaic solar plants on wet surfaces or on reservoirs and artificial water basins, both large and small, where conducive to other uses. For this typology, simplifications up to a power of 10 mW are applied”. it is also expected “Possibility to include it in the next stimulus decrees”,

Photovoltaic and floating wind power, advantages

among the benefits of floating photovoltaic Certainly the fact that it does not consume soil and valuable areas are not used for agriculture, the evaporation of water inside other reservoirs is low; The plant also generates a higher percentage of energy due to the cooling of the modules due to the presence of water.

The largest floating photovoltaic plant in Europe is under construction in the Alqueva hydroelectric dam basin in Portugal. With a launch by ED Renewables, it is targeted to start from July 2022. More than 12 thousand solar panels which make up the Alceva Floating Photovoltaic; There is a maximum power value of 5 MW for an estimated output of 7.5 gigawatt hours per year. The first Italian floating photovoltaic plant in the artificial basin of the Germanaire mine will be in Piedmont. Once the plant is ready, it will be possible to reduce pollution emissions, with savings of 3,500 tonnes of CO2 per year.

Ale’offshore wind Swimming is particularly beneficial where the sea floor is deep and so it is complicated, if not possible, to use shovels with traditional fixed foundations. The technology therefore broadens the possibilities of offshore marine areas that were previously closed due to the depth of the ocean floor. For example, the Scottish off-shore power plant, Kincardine, which went into operation last October and immediately won the record for the world’s largest floating wind farm, The project consists of 6 wind turbines of 50 MW total, Built at a distance of 15 kms. The coast of Aberdeenshire, where the sea level reaches even 80 meters deep.

The largest floating wind project in the Mediterranean is in the Egadi Islands, off the coast of Sicily; It will light the homes of 3.4 million households, and reduce CO2 emissions by about 2.7 million tonnes per year. Built by Toto Group’s Renexia, the Sicilian project, called Medwind, involves an investment of nine billion and involves the construction of an offshore wind farm with floating technology consisting of 190 floating turbines for approximately 2.8 gigawatts of installed power and estimated annual capacity. Production of 9 terawatt hours per year.
