As? Together An innovation in its design,
The device is called Zired and the key lies in its compressed air storage system, which allows it to save energy without using external batteries. To achieve this, it uses a special compressor located in the nacelle and which is itself activated by the rotation of the blades of the wind turbine.
Key: Compressed Air
Thanks to this rotation, the air is compressed in an internal tank, releasing what the company calls “potential energy”. When necessary, for example because the wind gusts are not strong enough, the system releases it with the help of motors and generators, convert it into electricity,
“Zired is a long-term storage device that conserves energy in the form of compressed air, a type of potential energy,” details the firm. over the gondola”.
Each motor and compressors have a weight about 100kg, Among its advantages is the Optimetron’s ability to produce electricity on demand, its low cost and the use of “only environmentally friendly materials” in the design, among which it explicitly cites the amount of ceramics, steel or concrete, which It assures, much less than other wind turbines.
Thanks to its potential energy, a zire motor located on the ground is fed, which is responsible for converting the energy into electricity by means of a commercial generator.
“Storage capacity of up to 2 GWh can be achieved in full and up to 4 GWh retroactively,” says the company, which claims that the compressor will continue to produce electricity even if renewable energy sources are no longer available. is capable of “day, week or month”Depends on both storage capacity and daily consumption.
The device focuses on one of the big challenges of renewable energy: its intermittency, which makes adjusting generation to demand a challenge and requires resorting to batteries and other backup sources. With its new development, Zyred has opted for a somewhat different strategy: a wind facility capable of conserving potential energy when needed.
