carbon neutral fresh water to the planet

Freshwater & CETO

The world is running increasingly short of freshwater. It is estimated that nearly 2/3rds of the entire world will be water scarce by the year 2030. Because 97.25% of the world's water is in its oceans and most of the rest is in ice caps, only 0.01% of all the water in the world is accessible without seawater desalination. Currently though desalination is very energy intensive and is therefore a greenhouse gas emitter. A 500kL/day desalination plant operating on Australia's eastern seaboard emits the equivalent of nearly 1,000,000 tonnes of CO2 per year or an extra 220,000 cars on the road every year*.

CETO differs from other wave energy technologies under development by pumping water directly ashore under high pressure rather than generating electricity offshore and transmitting it back to shore via high voltage cables.

This makes CETO the most efficient and cost effective way to desalinate freshwater from wave energy.

Other wave energy technologies will need to bring electricity to shore under high voltage, in order to run pumping stations that pump seawater ashore and deliver it to a desalination station. This introduces an inefficient additional step (electricity conversion to mechanical energy for pumping with associated losses), additional capital and operating costs associated with the pumps and additional onshore footprint.

By acting as an offshore pump, CETO delivers large volumes of high pressure seawater ashore ready for desalination via traditional (reverse osmosis) means (but without the greenhouse gas emissions).
