Wave Power

Wave Power

Wave energy comes from the large untapped currents in the ocean. By concept, it is very simple, however the trick is to reduce the cost of generation plants enough to make the process affordable. This is done in a number of ways, the most successful in Australia to date being the submersed floating buoy method. Hundreds of air filled balloons are submerged about 15 feet below the water surface and oscillate to the ocean currents pumping compressed water back to the coastline for energy generation.

It is perhaps counter intuitive that these currents are largely independent of the waves above them caused by wind, which means that in conjunction with wind farms, these plants increase energy consistency which is an important aspect of any energy mix.

Another advantage is the fact that compressed water can be fed through reverse osmosis plants which provide clean desalinated drinking water. Therefore if we find that there is energy provided than demanded, clean drinking water may be stored. Although a lot of our drinking water comes from rainfall, we are installing desalination plants to provide surplus water requirements, and the energy required to produce this water currently comes mostly from coal. I.e. when we water our garden, have a shower or fill the kettle we are burning coal to produce the desalinated water. If future water requirements were fed by wave energy, we would be harnessing clean water by the power of the ocean.
