The future of renewable energy lies in the rivers

What is the Energyfish by Energyminer?

The Energyfish is an innovative system for power generation that operates in perfect harmony with nature. This forward-thinking and highly sustainable energy source harnesses the power of water and produces electricity continuously in a river, 24 hours a day. This innovative micro-hydropower plant is capable of supplying energy to entire communities. What sets it apart is that the energy source is mostly submerged underwater and is hardly visible. The micro-hydropower plant operates silently and has been designed to pose no threat to fish. Unlike wind or solar power, the Energyfish is capable of providing baseload power, meaning it reliably produces electricity in all weather conditions throughout the year.

This means 100 percent clean renewable energy is available 24 hours a day generated locally all year round.

Each Energyfish directly feeds electricity through a low-voltage line into the local grid. The Energyfish is 100 percent flood-resistant, capable of submerging itself to continue generating power. Additionally, it requires minimal maintenance and has been engineered for maximum availability.

The Energyfish by Energyminer is the hydrokinetic power plant for clean energy generation in harmony with nature and the landscape.

The operating principle of the Energyfish underwater power plant

The Energyfish is a compact hydrokinetic underwater power plant designed for use in rivers. Within the Energyfish, there is a robust and highly efficient turbine system that is driven by the natural flow velocity of the river. A fish protection system, especially developed by scientists, reliably safeguards fish from disturbances or injuries in their natural movement. In the event of high water or ice formation, the Energyfish adapts to the situation by automatically sinking to the riverbed for safety while continuing to generate power. The Energyfish installations are monitored 24/7 by an intelligent remote monitoring system. Due to the well-thought-out design, the surfaces of the Energyfish remain free from algae and from catching other floating objects in the river. Water sports enthusiasts are also protected as the Energyfish installations can be easily pushed downward or aside without any risk of injury or impairment.

Answers to the most common questions

The Energyfish offers a variety of unique benefits:

  1. The installation of the Energyfish does not require any dam walls or concrete structures. The natural watercourse of the river remains unchanged, preserving its natural state.
  2. The operation of the Energyfish is completely silent, and its visibility is minimal, as it remains submerged underwater over 90% of the time.
  3. The design of the Energyfish ensures that it does not pose a threat to fish and instead offers special protection measures to ensure their safety and unhindered movement. Our hydrokinetic system is fully compatible with fish and their habitats.
  4. The Energyfish generates electricity continuously, serving as a reliable and consistent base load power source, operating 24 hours a day, 7 days a week.
  5. Rivers represent an inexhaustible and abundant source of energy for power generation, capable of providing constant power for centuries to come.

The Energyfish's unique advantages make it a sustainable and reliable source of energy.

In principle, the Energyfish can be used in many river sections.

An ideal river for Energyfish deployment must meet the following conditions:

  1. The river should have a minimum depth of 1 meter with a flow rate of at least 1 meter per second. It should also be wide enough at the desired location. A single Energyfish measures 2.4 meters in width and 3 meters in length.
  2.  Energyfish installations on large rivers are strategically positioned outside the shipping channels to ensure that they do not obstruct or interfere with shipping traffic.

After obtaining approval from the relevant authority, the installation of Energyfish can be swiftly carried out, enabling prompt commencement of electricity production. The installation of 10 systems typically takes approximately 3 days to complete. Subsequently, it is necessary to connect the Energyfish farm to the local power grid operator for integration into the low-voltage grid. This process ensures efficient and timely commissioning of the system.

The Energyfish is specifically designed to be low maintenance and self-cleaning. Due to its construction, floating debris simply floats by and algae cannot settle.

The long-term operational capability of the Energyfish was planned with a service life of well over 10 years. Each Energyfish is continuously monitored by an intelligent monitoring system that monitors power production, flow rate and relative location. In the event of irregularities, the system reacts immediately and notifies a service team to quickly intervene.

Thanks to this reliable and automated monitoring, the Energyfish can be operated efficiently and ensures high availability and performance over a long period of time.

It is not possible to purchase a single Energyfish. However, Energyminer offers the opportunity to participate in Energyfish schools. As a result, everyone can contribute to developing this innovative energy source and at the same time benefit from the advantages, such as protection against rising electricity prices.

Energyminer provides an all-round carefree package and takes care of the installation, operation and maintenance of the systems.

When developing the Energyfish, great care was taken to protect aquatic life. The Energyfish has been specially designed to ensure that it does not harm or negatively impact fish. The front grid of the Energyfish prevents larger fish from entering the rotors, while allowing smaller fish to swim through the slowly spinning rotors safely. Even in the unlikely event of a collision, the fish is only gently pushed away without sustaining any harm.

Furthermore, the implementation of the Energyfish does not disrupt the natural condition of the river. This sustainable approach simplifies the approval process and fosters a high level of acceptance within the affected community.

We place significant emphasis on safeguarding the environment and the fish population, and we ensure that the Energyfish operates in harmony with nature.

The Energyfish was developed with robust protective mechanisms to work reliably even during flood events where the river may be susceptible to a lot of floating debris. In high tide conditions, the Energyfish automatically dives and lets larger floating debris float over it unhindered. In addition, the Energyfish withstands the impact of large objects.

For the extremely rare case that debris accumulates on the Energyfish and a blockage occurs, provisions are in place. The Energyfish uncouples itself and is safely guided to the riverbank by an emergency anchor. In such a situation, the service team will be notified immediately to take the necessary measures.

The Energyfish was designed in such a way that there is no danger to people or animals.

The entire system works with a safe extra-low voltage of 60 volts. Even if the cables are damaged, there is no risk to people or animals. In addition, the streamlined design of the Energyfish ensures that swimmers and water sports enthusiasts cannot injure themselves.

The Energyfish is anchored to the river bottom by a steel cable and can be easily pushed deeper or sideways to ensure safe passage for swimmers and water sports enthusiasts.

The Energyfish only has a minimal and localized impact on the flow of the river. In the immediate vicinity of the Energyfish, the flow speed is slightly slowed down, but this does not represent a significant obstacle. After a short distance of 20 meters, the river recovers to its original flow speed.
