Thanks to Rabbit_042, we know that work is being done to find  a less expensive method of anchoring the buoys.

"This project aims to develop an economic and efficient anchoring system for taut-moored wave energy converters to enable us to exploit sustainable wave energy resources. Australia’s potential near-shore wave energy resource is four times larger than the current total capacity of our installed power generation. But the development of ocean wave energy is presently hampered by expensive, traditional anchoring systems. Using better estimation of extreme loads, the project will use multidisciplinary approaches to investigate unique anchoring concepts with the aim of developing novel strategies to avoid the most extreme loads and enabling optimum anchor design. The outcomes of the project are intended to help to deliver economically viable wave energy projects."
