In addition to wind energy, other innovations in renewable sources were exhibited during Show Rural Coopavel 2022

Never has so much energy been invested and consumed from renewable sources, such as wind energy, as it is today. In the last year, the increase in energy bills rose by 30% in Brazil, according to the Brazilian Association of Energy Traders (Abraceel), which encourages even more discussion about renewable sources.

At the Coopavel 2022 Rural Show, innovations in renewable energy stand out among exhibitors, such as the Paraná Rural Development Institute (IDR-PR), through the RenovaPR project, which encourages distributed generation (GD) of energy from renewable energy in rural units in Paraná. In total, 150 m² were used to expose wind energy and other renewable sources, such as solar, biogas and biomethane.

RenovaPR, a partnership between IDR and Ocepar (Organization of Cooperatives of Paraná), has means that can reduce energy expenses by up to 95%. So far, more than 1.600 projects have been assisted by IDR Paraná, with an amount of R$ 275,3 million. In all, the program has 431 companies registered in solar energy proposals and 15 in biogas/biomethane.

Featured renewable sources

According to the original text by Dirk Lopes for the rural channel, one of the highlights in the Rural Show space is the wind energy producer Hotek, a technology entirely from Paraná that should occupy the medium-sized equipment market. The Hotek Wind Generator is 23 m high and has the capacity to produce 24 hours a day, and can be used in rural or urban areas. Furthermore, the wind power generator uses aerodynamic duct, not blades.

Another piece of equipment worth mentioning is the electric generator, which starts producing wind energy with less than 1 m/s of wind, an excellent performance in relation to products that are already on the market, which start at 3,5 m/s of wind. It works both connected to the DG power grid and offline, having the capacity to sustain battery packs that allow energy independence for an enterprise.

The Hotek wind energy generator is installed in the RenovaPR environment for the experiment and measurement stage of energy production for field testing and final product certification. After the process, the responsible company and the equipment will be registered in RenovaPR and used as an option for producers and agroindustries.

Night lighting

In addition to renewable energies, the Rural Show also presents, through the Fienile Group together with the Itaipu Technological Park, the Irriluce Technology: artificial lighting for farming, which is already present in several states, such as MG, BA, SC and RS. Vilmar Steffanello, a wheat producer who has been using the Irriluce technology for more than a year, says that he had more than 50% growth in production in the last harvest.

For the first time in Santa Catarina, there was a second hop crop in the same year, due to light supplementation in the crop. The study is being carried out by Hyan de Cásio Pierezan, a master's student assisted by the State University of Santa Catarina.

The innovation uses LED modules juxtaposed to the pivot, to enhance the light and complement the photosynthetic process of plants throughout the night, which generates countless benefits.

Gustavo Grossi, CEO of Grupo Fienile points out that this is an excellent way to publicize the company's work. Due to the results achieved by the technology, he explains that the work does not correspond only to light, and that without soil nutrition, recovery of structures, management linked to remineralization technologies, innovation is not functional. “It's not just about investing in Irriluce Technology [...] You have to be willing to contribute to research, receive researchers on your property to evaluate the development of the project at least in the first three years”, he says.

The Fienile Group Research Director, Ernane Lemes, discusses the results obtained so far: “Luminous Supplementation is the culmination of a joint effort, which begins with a consultation with each producer to understand what his area presents in terms of possible limiting factors and what can be improved in terms of management, soil structure, soil chemistry, plant nutrition. It would be no use to position the light if the plant is unable to extract nutrients, extract water to develop”.

The presence of the Fienile Group is essential to correct misperceptions regarding the project. “The importance of being at the event is to position a correct idea of ​​the project and serve those participants, those producers who are interested in technology, to do beyond the commercialization and sale of the project, the positioning of the project that goes beyond the light, but what a crown with the implementation of light supplementation”, concludes Ernane.
