Utilización de energía hidráulica con elementos de centrales energéticas sumergidas


Oferta Tecnológica
Una pyme húngara especializada en ingeniería civil y actividades de I+D ofrece un método de utilización de energía hidráulica. Sus principales ventajas son su sistema modular que se divide en elementos más pequeños, la inversión relativamente baja que requiere la solución y que alcanza una alta cuota de mercado, su gran versatilidad y mantenimiento y funcionamiento sencillos. La empresa busca socios con el fin de establecer acuerdos de licencia, investigación y cooperación técnica.


Hydropower utilisation with underwater power-plant elements
A Hungarian SME dealing with civil engineering and R+D activity offers a hydropower utilisation method. The major benefits are its modular system which can be divided into smaller elements; the relatively small investment that the solution requires can deliver high market share and given the smaller components involved, its greater versatility, improved ease of maintenance and simple operation. The company looks for partner interested in licensing, research and technical cooperation agreement.
The company has been operating successfully on the Hungarian market for 20 years and in that time has gained extensive experience in civil engineering and R+D activity, and obtained a number of patents and considerable know-how. Hydropower utilization is one of the greenest solutions currently available and is less visually intrusive and harmful on the landscape.

Maintenance and operation
The ring generator elements are of standard construction and linked to one another by means of a changeable standard closing panel.
These connections simply dissolve and can easily be replaced. Installation is quick and simple, and can be carried out within a relatively limited underwater area. Modules are identical and therefore entirely interchangeable. Maintenance work, such as repair, assembly and disassembly, the maintenance ship transport to the land, such as the repair work can be carried out under normal operating conditions.

Time of return on investment does depend on the state subsidies available, but will nevertheless be much shorter than that on traditional land water plants. Calculated on the basis of 4 cents/kWh, and without factoring in operational costs, over a 10-year period a 1MW underwater power plant would generate $21,000 of electricity, a 5MW plant $264,000, and an 11MW plant $580,000 (almost 220days/year).
A non-profit organisation can produce one ring generator for $140 at most, which would cost a profit-oriented enterprise twice as much.
Even without state subsidies being forthcoming, this kind of renewable energy can become increasingly used.

Water is 800 times denser than air. This means low flow rates using a smaller diameter wheel can deliver greater efficiency, particularly in comparison to wind power plants, besides the clear advantages in sustainability and continuous, calculable energy supply.
A 4-knot (7 km/h) ocean current is flowing at ˜2m/sec when it passes through the contracted area of the cylinder causing the flow rate to increase to 6m/sec/m³. Significantly higher currents may be generated by river regulation and other water engineering solutions.
The novelty is that there is no central axis towards the periphery of the circular center panel hanging paddle boards handed over to the generated torque to the ring. The two rings are separated by an intermediate layer of air (floated) or water (lubricious).The generator may be permanent magnetic or electromagnetic, or mixed.
The Hungarian SME is looking to enter into a licensing- and/or research- and technical co-operation agreement with H2020 partners, constructors and licensed trading companies. The type and size of the partner can range from university research teams to private companies with up to 500 employees.
Advantages and Innovations:
Previous solutions
Large underwater areas are required and, due to the length of wiring involved, maintenance work is difficult. The significant height of generators can pose a danger to shipping and clear warning signs need to be positioned demarcating such hazards. Traditional solutions significantly impact the landscape and natural environment. Typically, given that mechanically engineering large hydropower plants requires water to be raised to and then forced down from a great height, thereby causing turbine blades to spin at high speeds, considerable infrastructural development is required, impacting water levels and the natural habitat of the local wildlife, while generating relatively low levels of energy.

Advantages of the new solution
The major benefit of the underwater power plant is that it comprises a modular system, meaning it can either be divided into smaller elements or optionally combined to increase capacity as necessary. The solution requires relatively small investment and can deliver high market share, and, given the smaller components involved, offers greater versatility, improved ease of maintenance and simple operation. Avoiding visual pollution is also a key consideration, which is not possible with the placement of underwater wind turbines and conventional land-river hydroelectric power plants.
The innovation is to build a modular underwater generator using barrel-shaped cylinders. These are connected to one another both horizontally and vertically, secured to the substrate and fixed by means of beams. A slow-speed (10-30 rpm) ring generator with no central axis utilizes the movement of the flowing water and, given that water 800 times denser than air, a much smaller water blade is required than would be the case in a wind power plant. In accordance with Bernoulli´s principle, the center of the cylinder elements is contracted, thereby increasing the useful speed of the water flowing through it by up to two or three times.
