The company Emrgy creates “EnergyFlume” capable of generating 10 kW with each module of its scalable system. When talking about hydroelectric power stations, the first thing that arises is the need for a large and fluid flow, this system works by means of large generators capable of meeting the needs of small towns. Although the method is expensive and disruptive to the environment, it is effective, however, the Emrgy company set itself a bigger challenge: to create a modular system that manages to extract electrical energy from slow water currents. Like the canals. or rivers.
Emrgy is an Atlanta-based ‘startup’, whose field of action is based on the treatment of aquifers for energy, in this research it attempts to achieve two objectives, the efficiency of its methods as well as the respect the environment.
In the quest to limit global warming, one of the issues that arises is the production of energy from renewable sources, as well as the reduction of the environmental impact of production systems. Water is one of them, capable of generating continuously, 24 hours a day all year round, so taking into account hydropower systems is a potentially viable solution.
Emrgy has succeeded in developing a module-based management system that manages to generate power from slow water currents, including canals or rivers. Each module of this system manages to generate 10kW, because the system is scalable, it is easier to use.
The method the company has created is based on a design that seeks minimal environmental disturbance, both in the orography and in the local aquatic population.
Emrgy’s patented structure is called EnergyFlume, it consists of modules built with inert materials, they do not decompose over time, adding debris or foreign matter to the local water supply. Each element is prefabricated, so it does not require a construction base where it is to be implanted, which reduces costs and simplifies installation.
The design allows individual stability to each module, capable of accelerating water flow by up to 200%. A pair of twin blades in the turbine complement each other and can capture up to 70% of the energy available at the time.
An automatic start system on each part allows flowing water to be directed in specific directions. It also has a magnetic gearbox which provides the rotational movement of the turbines to the generator with greater efficiency than a mechanical gearbox, this compensates for conditions of excessive speed or excessive force that may be generated. One of the first prototypes of this system has already been installed in Denver, the company Denver Water was commissioned to carry it out.
The implementation of a small-scale hydropower system results in a reduction of almost 4% in energy needs in the world, on a larger scale. At the same time, around 4 gigatons of carbon dioxide would be avoided in the atmosphere, which is equivalent to more than 800 million vehicles running on fuels such as petroleum, coal or natural gas, among other fossils.
