Renew Blue is the first licensing entity of the Seadog Pump from Independent Natural Resources. The Seadog Pump technology  harnesses wave-power to generate electricity. The pump uses wave motion to drive a piston which pumps water through an exhaust pipe. This water is then collected and passed through standard turbines to make electricity when needed, returning the water to its source. Renew Blue will bottle and distribute the freshly desalinated water which it claims to be the first 100% fossil-fuel free bottled water.

 

Renew Blue will place an offshore modular platform about one mile (1,500 m) off the coast of Freeport, Texas, in roughly 25 ft (8 m) of water at the end of 2009/beginning of 2010. The platform, being manufactured in Houston, will store up to 30,000 gallons in a sealed, stainless steel tank before the water is transported to the bottling plant. The Seadog pump system claims significant cost savings and minimal environmental impact compared with use of power generated by fossil fuels. Further environmental benefits accrue from the manner in which reject brine is disbursed.

Preliminary estimates based on results from the sea trial suggest that a one-square-mile field of Seadog pumps could generate 30-1,500 MW electricity. The amount of electricity generated is dependent on how large the waves are in any given area of the world.
