Why Tidal?
Tidal power is uniquely well-suited to diesel-dependent coastal grids because it’s abundant and predictable: tide cycles can be forecast years in advance. This enables communities to plan confidently and displace a meaningful share of diesel. In energetic channels, tides also offer high power density, delivering substantial electricity within a compact footprint where land is limited or onshore impacts matter. And because tides move day and night, tidal can provide a steady backbone that complements wind and solar, reducing the storage and grid-balancing required for a resilient energy system.
The Yourbrook Edge
Yourbrook’s patented technology is built around four principles:
Storage built in
Pump-storage efficiently captures energy during high-velocity periods and sustains generation through slack tide, turning intermittency into firm supply.
Surface-mounted access
Key components remain accessible above the surface, reducing seafloor disturbance, simplifying inspections, and lowering maintenance risk.
Smart mechanics
The turbine operates on both ebb and flood, while swash plate inclination can be tuned to optimize mechanical advantage across variable tidal speeds.
Scalable architecture
Depending on site conditions, multiple pump units can be stacked to increase generating capacity.
Technology Highlights
-

Variable-stroke pump
A tidal-driven variable stroke swash plate pump designed to maintain constant output pressure regardless of incoming torque, validated through prototype field testing (>6,000 operating hours)
-

Dynamic foils
A patented dynamic foil based on an elliptical blade path, designed to increase swept area and energy extraction; early testing indicates strong performance.
-

Pump-storage
Up to two-reservoir configuration (upper accumulator and lower sump, if needed) that can operate as a closed freshwater loop or open seawater intake depending on site topography, enabling continuous output through an entire tide cycle.
