NMANews2015.5.3---澳大利亚CETO海浪转化能源和淡化海水系统
An Australian company has been working on a system that uses underwater buoys to convert sea waves into zero-emission energy and desalinated water.
Australian firm Carnegie Wave Energy has been developing a system called CETO, which aims to utilise sea waves to generate power. Steel-made buoys that can currently generate 240 kilowatts are the main part of the system.
At the Australian naval base HMAS Stirling, three buoys are placed 11 kilometres apart. The buoys are less susceptible to extreme weather damage, while underwater waves are sufficient to generate power.
The buoys’ pumps drive the high pressure water to an onshore power plant via a subsea pipe. The high pressure water spins the turbines, which then generate zero-carbon electricity.
The CETO system can be used to power a desalination plant as well. High pressure water can be utilised to remove salt from seawater through a permeable membrane in a process called reverse osmosis.
The Australian company believes that the cost of electricity generated by the CETO system will be competitive with diesel if it is deployed at a large scale.
一家澳大利亚公司一直使用水下浮标海浪转化成零排放的能源和淡化海水的系统上。
澳大利亚公司卡内基波能量已经开发了一个名为CETO系统，该系统旨在利用海浪发电。钢制浮标，可以目前产生240千瓦是该系统的主要部分。
在澳大利亚海军基地HMAS斯特林，三浮标放置11公里分开。浮标不易受到极端天气损坏，同时水下波浪足以产生电力。
浮标“泵经由海底管道驱动所述高压水到陆上发电站。高压水旋转的涡轮机，然后产生零碳电力。
该CETO系统可以用来驱动一个海水淡化厂，以及。高压水可以利用从海水通过渗透膜在一个称为反渗透过程以除去盐。
澳大利亚公司认为，电力由CETO系统产生的成本将与柴油竞争力，如果它部署在一个大的规模。
