L’tidal energy attracts growing interest in the field of renewable energies. A remarkable innovation in this sector has just been validated by a recent study. THE screw-shaped tidal energy converterdesigned by the British company Spiralis Energy, has demonstrated its effectiveness during extensive tests.
Technology inspired by nature
The unique design of this converter is inspired by marine shellsthus combining biomimicry and cutting-edge engineering. Spiralis Energy developed this technology with the aim of creating one device at a time resistant and durable. Unlike other marine energy exploitation systems, this converter is distinguished by its characteristic helical shape.
One of the most innovative aspects of this project lies in the use of plastic waste for its manufacture. This approach fits perfectly into a logic ofcircular economythus reducing the environmental impact of the device. Guy Levene, CEO of Spiralis Energy, highlights the importance of this approach: “Our technology can provide a renewable energy source that does not harm marine life and is part of the circular economy. »
Validated by rigorous testing
Marine technology consultancy Cape Horn Engineering conducted a validation analysis in depth of the converter. The results obtained are particularly encouraging:
- Prediction by numerical simulation: 2.59 kilowatts (kW)
- Actual measurements on the prototype: 2.50 kW at 21 rotations per minute (RPM)
- Difference between prediction and measurements: only 1.5%
This remarkable precision shows the reliability of the simulation model used and supports the predictions for future large-scale versions of the converter. Rodrigo Azcueta, Managing Director of Cape Horn Engineering, says: “With this validation stage completed, we can have even more confidence in our prediction that the full-scale unit will exceed the 250 kW threshold. »
Promising prospects for the energy future
With these convincing results, Spiralis Energy is preparing to move on to the next phase of its trials. A large-scale tidal energy converter is in preparation, with impressive dimensions:
| Characteristic | Dimension |
|---|---|
| Length | 16 meters (52 feet) |
| Diameter | 5 meters (16 feet) |
The company plans to install two of these converters in the Some to evaluate their performance in more severe winter conditions. Fluid dynamics analyzes carried out by Cape Horn Engineering will optimize the shape of the converter and identify structural loads, thus ensuring maximum performance.
Spiralis Energy has considerable ambitions for the UK’s energy future. The company aims to provide 11% of annual energy demand of the country thanks to the electricity produced by its marine converters. This perspective is in line with national efforts to develop renewable energy and reduce dependence on fossil fuels.
Modular and ecological technology
The innovative design of the screw-shaped converter has several major advantages:
- Partial submersion: only the lower part is submerged
- Generating electricity above water: drier and safer conditions
- Modular design: facilitates maintenance and repairs
- 3D printing: allows local manufacturing of spare parts
This approach modular and decentralized provides increased flexibility in facility management and maintenance. In the event of damage, necessary parts can be printed and replaced quickly, reducing downtime and logistics costs.
L’tidal energy stands out as a particularly promising source of renewable energy. Available 24 hours a day and predictable, it can provide a continuous and reliable electricity supply. The success of Spiralis Energy’s converter marks an important milestone in the development of innovative and sustainable marine technologies, paving the way for a new era ofclean energy infrastructure.
