Why Tidal?

It all begins with an idea. Maybe you want to launch a business. Maybe you want to turn a hobby into something more. Or maybe you have a creative project to share with the world. Whatever it is, the way you tell your story online can make all the difference.

The Yourbrook Edge

Yourbrook’s patented technology offers a number of competitive advantages:

  • STORAGE: Using pump-storage, our system efficiently harnesses and stores tidal energy providing a continuous power source from an intermittent resource

  • SURFACE-MOUNTED: Our system is permanently mounted above the surface, not submerged, which minimizes seafloor impacts, reduces complications arising from biofouling, and simplifies component access for easy maintenance

  • SMART: Not only can the turbine operate both ways (i.e., on each flood and ebb tides), the inclination of the swash plate can be adjusted to increase/decrease the pump stroke, maximizing mechanical advantage over a range of tidal stream velocities, including low speeds

  • SCALEABLE: Depending on the site, more than one pump unit could be stacked out into the tidal stream, increasing electrical production capacity

Why Tidal?

Tidal energy is natural, abundant, and largely untapped. Our technology allows us to harness this power without significant disruptions to marine ecosystems or creating carbon-intensive emissions. For many off-grid coastal communities, utility-scale renewable projects are often too expensive due to large energy storage requirements while limited access complicates infrastructure development.

Technology Highlights

  • Pump

    Yourbrook has innovated a variable stroke swash plate pump that is driven by the tidal stream. It has the ability to maintain a constant output pressure regardless of incoming torque. This design has been field-tested via a prototype that, to date, has successfully operated for over 6000 hours.

  • Dynamic Blades

    Yourbrook has also developed and patented a dynamic tidal turbine that is based on an elliptical blade path, which vastly increases swept area and power output. Initial test results have exceeded expectations and indicate superior energy extraction.

  • Pump-Storage

    Yourbrook’s design incorporates two reservoirs: an upper (accumulator) and lower (sump), which can operate either via closed freshwater loop or open seawater intake, depending on site topography. During times of high current velocity in a given tide cycle the volume of water pumped will exceed the required volume of the hydro turbine; this excess volume will accumulate in the upper reservoir and flow back down through the hydro turbine during periods of slack tide, thus providing continuous power.
