Unlocking the ocean
Hydrakraft has solved the fundamental challenges of exploiting the vast wave energy resources along the coast and in the world's oceans.
Patented extreme wave handling
Low cost of energy
Lean and rapid installation
Smallest footprint of all renewables
How it works
(1) A float absorbs energy from the waves on rising wave motion.
​
​​(2) The absorbed energy is geared up by a submerged seabed anchored pulley system and transferred mechanically to land by means of a wire/rope (3).​​
​
The wire motion causes a winch (4) on land to rotate.​​ Inside the winch unit, the absorbed mechanical rotational energy is converted to hydraulic energy, and then to electricity.
