Capturing the massive power generated by waves
Wave energy remains one of the world’s last great untapped sources of renewable energy.
At Artemis Intelligent Power we have been working in wave energy since the 1970s – our company originated as spin-off from the pioneering Wave Power Group at the University of Edinburgh.
Although the industry has seen significant advances in the last ten years, there are are still considerable challenges in making electricity from waves. In particular, wave converters have to capture the highly irregular energy from slow-moving waves and turn this into a reliable and cost-effective stream of electricity.
We are now working with wave engineering consultants Quoceant on a £2.5 million project funded by Scottish agency Wave Energy Scotland to trial a prototype which aims to do just that.
Together we have developed a technology called ‘Quantor’ which for the first time includes the use of Digital Displacement hydraulics to tame the massive but slow and erratic power output of wave energy machines.
We believe our system is a fundamental advance in capturing the mechanical power generated by waves. Quantor combines the established advantages of hydraulic power – controlling tremendous forces in harsh environments at comparatively low cost – with the latest in smart digital control, to enable dramatic improvements in efficiency and controllability of wave energy devices.
Now with Wave Energy Scotland’s backing, we will build and demonstrate a complete hybrid power transmission on a unique laboratory test-rig. This will simulate the behaviour of a wave energy converter responding to a range of different real sea conditions.
The project gives us the opportunity to build and demonstrate a completely realistic power conversion system that has the capacity to work at sea.
