WAVE ENERGY

Wave energy converter

Wave Energy is store of renewable energy found around the world in our oceans and seas. The World Energy Council estimates the available energy to be approximately over six times today’s global electrical energy needs.

Sigma is dedicated to environmentally friendly usage of wave energy and promotes a patented technology that is based on a simple, effective concept which has minimum impact on the environment, can be used in wave fields as small as one meter, is modular allowing sizing and number of units to suit specific requirements, and also need minimum maintenance.

The entire device consists of the offshore section that includes a a wave driven cylindrical float, a hydraulic piston and the anchoring system, in conjuction with the shore section that uses the energy to produce water or electricity, or both.

The waves cause a reciprocating motion of the piston due to the buoyancy of the float. Thus, seawater is pressurised and conveyed through a pipeline to a pressure chamber in the shore section, which regulates sea water pressure and flow in order to be stable. This pressurised water can then be channeled either for desalination through R.O. or for electricity through a hydroelectric turbine.

It is designed for the harsh conditions found at sea and can continue operating even under storm conditions no matter how high the waves are. Its exceptional ability to make use of the smallest waves to provide fresh water also stand out.

Whether the need is permanent or temporary, its modular design is ideal for providing an autonomous solution for any application: such as community drinking water, bottled water, farming, industry, Hotels, pumping water, fisheries, cooling water, humidity production, air conditioning, swimming pools, seawater agriculture, or even personal use.
