Fuel For The Future... Tidal Power

It's official, the Earth is warming up faster than at any other time in its history – Our life style over the last 50 years has created vast amounts of CO2. As CO2 is a heavier gas than air, it acts like a blanket around the planet keeping the heat inside. As the atmosphere warms up, so the polar ice caps are melting, causing sea water levels to rise and weather systems to change. Many countries around the globe are looking to cut down their dependence on fossil fuels.

There are other sources of energy out there, such as wind and solar but they undependable and are often geographically limited. So they can only offer some of our energy needs. As for nuclear energy, well it too comes with its problems not least, its a dangerous power source and its waste elements are deadly.

So there are limitations in all of the various sources of energy, so we need to explore other options, something new, interesting and constant? And that is when scientists found that wave power could be the perfect solution for our clean energy needs. The tremendous power of the waves and tides can be used create clean and green energy.

But harnessing the power of the waves is no cheap matter, new technology can cost millions. The ferocious ocean play a part in this and create a very testing environment for the design and harnessing of all this power. Various countries and their governments are confident of overcoming these obstacles and developing the wave power to fuel our future needs.

Countries are coming together to share the costs related to the wave energy projects. One such country is taking a key stance in this arena, Australia – is taking steps to utilize the wave power to produce green electricity.

The Perth Wave Energy Project is the world’s primary commercial wave energy range that is linked to a grid which can desalinate water. Wave energy is harnessed when electricity generators are kept on the surface of the ocean. The powerful waves are used to turn turbines which are responsible for generating electricity. The green energy thus produced is commonly used in power plants, desalination plants and in water pumps.

The high-pressure water generated by the CETO Units can be utilized to power a reverse osmosis process in a desalination plant, to a large extent reducing the need for dependence on fossil fuels, which produce the greenhouse gases otherwise produced by the fossil fuel dependant pumps.

The Perth Wave Energy Project will sell the green power to the Department of Defence for HMAS Stirling, which is Australia’s prime naval base situated on Garden Island in Western Australia.

Military defence bases and distant islands usually face problems such as high power bills, freshwater shortage and dependence on fossil fuels to produce power. Carnegie’s CETO Wave Energy technology is the best solution to generating both clean power and desalinated water. This is a significant milestone in the process of exploring and utilizing the huge wave energy potential in Australia.
