Italian and European technologies that will lead us to the energy transition – Corriere.it

The windows store light and convert it into energy, and the sandblaster battery allows you to store and release excess energy in the absence of sun and wind

a Photovoltaic system that can be installed without the need for technicians in the garden or on the balcony To produce electricity independently. Many startups, from Austria to France to the Netherlands, but also in Italy are trying to spawn technologies that could change the race towards solar energy.

Austrian startup Eet has created the LightMade board With a yield of about 425 kWh, roughly one-sixth of the average annual consumption of a family of three. In France, on the other hand, the photovoltaic organic roof was opened (which replace crystalline silicon with polymers and other photoactive components) in the world, in a middle school in La Rochelle is able to cover about 15% of the needs. Produced by German Heliatek. It is a roof-adhesive thin film solar (HeliaSol) connected to pre-made wires to turn facades and rooftops into clean energy plants.

Optical Italian windows

In Italy glass to force, which was listed on Euronext Paris a few days ago and was born as a subsidiary of the University of Bicocca in Milan, produces photovoltaic insulating glass units that can be assembled in series. These glasses – attached Emilio Sassoon CorsiFounder and CEO – They can be installed on any type of window, but they work best on continuous glass because they generate more energy. With sunlight, nanoparticles in the plexiglass plate inside the double glass convert visible light into infrared: This moves towards the tiny invisible photovoltaic cells on the edges of the glass that converts them into energy. The yield is 20/30 watts per square meter, which is about one-eighth the yield of classic solar panels, which will increase with new versions of the technology.

towards moving

We need to take advantage of innovative solutions, such as floating photovoltaic platforms and wind power, several miles from the coast. Only then will we be able to talk about the transition, and only then will it make sense to buy an electric car, he said Energy Transition Minister Roberto Cingolani
. To achieve the goals set by the Paris Agreement, it will be necessary to quickly switch to sun, wind and batteries. This will save us trillions of euros and reduce the impact of fossil fuel prices. However, factory facilities must be huge, as happens, for example, in the Netherlands, a country that uses technologies such as technology solar duckwho realizes Offshore PV Platforms.

Overcoming clean energy cuts

One of the problems clean energy As is known, the sources are cut off. Solar and wind energy depend on weather conditions. This deficit is still being compensated today by resorting to the production of energy from fossil sources. But, back in our country, technologies made entirely in Italy such as Magaldi Green EnergyWhich offers the first solutions to the problem: a storage system that allows you to use clean energy on demand, in the absence of sun and wind. This is an accumulating technology based on a fluidized sand bed, also known as a sand battery. It can be charged with excess electrical and thermal energy, managed to store for a period of 4 hours to weeks, with very limited losses, and then discharged when no sun and wind are available.

The situation in Italy

Italy is well ahead compared to other European countries, but it lags behind the Paris goals. According to the Director of Energy Services, in the electricity sector, 37% of Italian consumption in 2020 was satisfied with renewable sources. So far, about 32 gigawatts of solar and wind power have been installed in Italy – he says Diego Biasi, CEO of Quercus Real AssetRenewable energy investment fund. The goal is to double what has been accomplished in the past 15 years by 2030. We need a change of pace that starts with reducing bureaucracy. Data published by Terna estimates that dozens of projects related to PV and wind energy are still on the waiting list; Interventions that would lead the country to a complete energy transition. Countries have set ambitious goals for 2030-2050, which cannot be achieved in the current legislative context, which is why some governments are trying to make regulatory processes more efficient and quickly build new infrastructure to meet the goals, concludes Biasi.

The Sky Limits Carbon Tracker 2021 report argues that the amount of sunlight hitting the Earth’s surface in one hour will be enough to cover the world’s energy needs for a year. Moreover, the cost of renewable energy plants is gradually decreasing. In the meantime, experimentation with transition techniques that seek to mitigate the impact of fossil resources is multiplying: from carbon capture In the Planting trees to offset energy expenditures and CO2 emissions. When it is enough to appeal to the sun that lights us every day.
